Greenhouse ventilation fans help remove hot, humid air, but the right choice depends on your structure, airflow needs, and how much control you want. I rank the iLIVING 20-Inch Shutter Exhaust Fan as my best overall pick for growers who want a larger exhaust fan with thermostat and variable-speed control. The VEVOR 14-Inch stands out for temperature and humidity controls, while the Amico 10-Inch remote model suits smaller spaces that benefit from remote operation. The main tradeoffs are airflow capacity versus fan size, automatic controls versus setup simplicity, and exhaust fans versus small circulation fans. Read on for the full comparison and guidance on choosing a fan that fits your greenhouse.

Key Takeaways
- The iLIVING 20-Inch is my best overall pick for growers seeking a larger shutter exhaust fan with thermostat and variable-speed control; its size makes careful matching to the greenhouse opening especially important.
- VEVOR’s 14-Inch and 16-Inch controlled models add temperature and humidity management, a useful distinction for growers who want more than thermostat-only automation.
- Small grow spaces may be better served by the Amico 10-Inch or Windigaga 8-Inch than by the larger wall-mounted options, though their stated airflow and control features differ.
- The VIVOSUN AeroWave E6 and 5-inch dual fan are circulation choices, not substitutes for a wall exhaust fan; they move air within a growing area rather than directly venting it outdoors.
- Airflow figures alone do not settle the choice: opening dimensions, duct or wall resistance, replacement-air paths, control preferences, and greenhouse layout all affect a fan’s practical fit.

VIVOSUN AeroWave E6 Gen2 6-Inch Oscillating Grow Tent Clip Fan
I’d choose the VIVOSUN AeroWave E6 Gen2 to keep air moving around plants, rather than to exhaust hot greenhouse air outdoors. Its 320 CFM airflow, adjustable oscillation, and clip mount make it useful for directing circulation between benches or around a compact growing area. Compared with the wall-mounted iLIVING 12-Inch Shutter Exhaust Fan, it occupies little space and offers more targeted airflow, but it cannot match that fan’s exhaust capacity or automatic shutters.
Ten speed settings and app control add flexibility, though only five speeds are available without a compatible VIVOSUN GrowHub. The IP54 rating suits humid grow spaces, but this is still a corded circulation fan, not a substitute for a properly sized exhaust system when heat and moisture need to leave the greenhouse.
Pros:- Clip mount fits round or square poles, keeping the fan off benches and walkways.
- Adjustable oscillation and 320 CFM airflow help spread air through a growing area.
- IP54 rating is suited to humid grow spaces.
- Normal and natural wind modes, plus app control with compatible VIVOSUN GrowHub devices.
Cons:- Does not provide the outdoor exhaust function of wall-mounted shutter fans.
- Only five speed settings are available without app connection.
- App control requires a compatible VIVOSUN GrowHub device.
Best for: Greenhouse growers who need compact, adjustable air circulation among plants and have a suitable pole or frame for the clip.
Not ideal for: Growers seeking to exhaust substantial heat or humidity outdoors, or buyers who want all ten speeds without a compatible VIVOSUN GrowHub.
- Fan size:6 inches
- Airflow capacity:320 CFM
- Power:12 watts
- Noise level:33 dB(A)
- Speed settings:10 with app; 5 without app
- Oscillation:5-level automatic oscillation
- Mounting type:Clip-on
- Connectivity:App control; compatible with VIVOSUN GrowHub E42, E42A, and E25
Our verdict“Choose this fan for adjustable, humid-space circulation around plants, not as your primary greenhouse exhaust fan.”
iLIVING 12-Inch Wall-Mounted Shutter Exhaust Fan with Thermostat and Variable Speed Control
For a greenhouse that needs dependable wall exhaust without stepping up to a large fan, I’d shortlist the iLIVING 12-Inch. Its 960 CFM capacity, thermostat control, and three speeds offer more airflow management than the single-speed VEVOR 16-Inch Shutter Exhaust Fan, while its smaller format may better suit a modest structure. Automatic shutters open during operation and close when the fan stops, helping limit drafts and exposure through the wall opening.
The galvanized steel frame and aluminum blades are a practical fit for ventilation duty, and UL/cUL listing adds a clear electrical safety credential. The tradeoff is installation: this unit requires hardwiring, so it is less convenient than the VEVOR model’s pre-wired cord. Its listed 65 dB noise level also makes it a poor choice near quiet work or relaxation areas.
Pros:- Thermostat and three speed settings allow more control than a single-speed exhaust fan.
- Automatic shutters open and close with fan operation.
- Galvanized steel frame and aluminum blades suit ventilation use.
- UL/cUL Listed and includes OSHA-compliant wire guards, according to the product data.
Cons:- Requires electrical hardwiring for installation.
- Listed noise level of 65 dB may be distracting in quieter spaces.
- Its 960 CFM capacity is lower than the 1,500 CFM VEVOR 12-inch model.
Best for: Owners of small to mid-sized greenhouses who want thermostat-led exhaust, automatic shutters, and adjustable speed in a wall-mounted unit.
Not ideal for: Buyers who need plug-in installation, very quiet operation, or more exhaust capacity than 960 CFM.
- Airflow:960 CFM
- Coverage area:Up to 1,400 sq ft
- Voltage:115 V
- Power:65 W
- Number of speeds:3
- Temperature control range:32–130°F
- Noise level:65 dB
- Mounting type:Wall mount
- Materials:Galvanized steel frame; aluminum shutters and blades
Our verdict“Pick this for a smaller greenhouse needing thermostat-controlled wall exhaust, provided hardwiring and its listed noise level are acceptable.”
VEVOR 12 inch Exhaust Fan, Wall Mounted Attic Fan with Variable Speed, Temperature & Humidity Controller, 1500 CFM, Automatic Shutter
The VEVOR 12-inch exhaust fan stands out for buyers who want the fan to respond to both heat and humidity, not temperature alone. Its controller offers temperature and humidity triggers, ten speed settings, and a timer—more adjustment than the three-speed iLIVING 12-Inch Shutter Exhaust Fan. With up to 1,500 CFM, it also provides more listed airflow than that iLIVING model, which can help clear warm, damp air faster when the greenhouse needs stronger exhaust.
The automatic shutter closes when the fan is off, and the alloy-steel build is aimed at indoor and outdoor use. The tradeoffs are substantial: the listed 67 dB noise level is not especially quiet, and installation calls for electrical wiring and mounting hardware. I’d verify the unit’s 240 V specification against the greenhouse’s available supply before choosing it.
Pros:- Temperature and humidity triggers can automate ventilation for changing greenhouse conditions.
- Ten speed settings and a timer allow more adjustment than the three-speed iLIVING 12-Inch model.
- Up to 1,500 CFM exceeds the listed airflow of the iLIVING 12-Inch fan.
- Automatic shutter closes when the fan is off.
Cons:- Listed 240 V supply may not suit a greenhouse with only standard 115–120 V power.
- Listed noise level of 67 dB may be noticeable.
- Installation requires electrical wiring and mounting hardware.
Best for: Greenhouse owners who want automatic responses to both temperature and humidity and can provide compatible electrical wiring.
Not ideal for: Growers with a 115–120 V-only supply, those seeking quiet operation, or anyone wanting a plug-in installation.
- Fan size:12 inches
- Airflow capacity:1,500 CFM
- Voltage:240 volts
- Power:50 watts
- Number of speeds:10
- Noise level:67 dB
- Motor type:EC motor
- Mounting type:Wall mount
- Material:Alloy steel
Our verdict“Choose this when temperature-and-humidity automation matters more than quiet running or plug-in simplicity.”
iLIVING 20-Inch Wall-Mounted Shutter Exhaust Fan with Thermostat and Variable-Speed Controller
When a greenhouse needs substantially more exhaust than a 12-inch fan can provide, the iLIVING 20-Inch is the high-capacity choice in this group. Its listed 3,368 CFM airflow and coverage of up to 5,000 square feet put it well ahead of the 960 CFM iLIVING 12-Inch model. A thermostat and three speed settings provide basic temperature-led control, while automatic shutters close when the fan is off.
This is a wall-mounted installation, not a flexible circulation fan like the VIVOSUN AeroWave E6 Gen2; it is meant to move greenhouse air outdoors through a suitable opening. That capacity comes with a larger, heavier unit, 253 W power draw, and a listed 69 dB noise level. I’d reserve it for a large structure with a proper wall location and enough ventilation demand to justify the added scale.
Pros:- 3,368 CFM airflow is substantially higher than the iLIVING 12-Inch model’s 960 CFM.
- Thermostat and three speeds offer temperature-led ventilation control.
- Automatic shutters close when the fan is off.
- Galvanized steel frame and aluminum blades and shutters are suited to exhaust use.
Cons:- Wall-mounted design requires an appropriate opening and installation location.
- Listed noise level of 69 dB may be disruptive near quiet areas.
- At 26 lb and 23 inches wide and high, it is a sizable installation.
Best for: Owners of large greenhouses with a suitable wall opening who need high-capacity, thermostat-controlled exhaust.
Not ideal for: Small greenhouse growers, buyers without a wall-mount location, or anyone prioritizing low noise and compact equipment.
- Airflow:3,368 CFM
- Coverage area:Up to 5,000 sq ft
- Power:253 W
- Voltage:115 V
- Motor:1/5 HP direct drive
- Number of speeds:3
- Temperature control range:32–130°F
- Noise level:69 dB
- Weight:26 lb
Our verdict“Pick this for a large greenhouse needing powerful, thermostat-controlled wall exhaust, not for compact spaces or quiet operation.”
VEVOR 16-Inch Shutter Exhaust Fan, Wall-Mounted Automatic Louvers, Silver, Steel Housing, 2438 CFM, Low Noise AC Motor
The VEVOR 16-Inch Shutter Exhaust Fan is a practical middle ground for growers who need more exhaust than the 12-inch models but do not need the scale of the iLIVING 20-Inch. It moves up to 2,438 CFM and has rain-guard shutters, while its pre-wired power cord can simplify installation compared with the hardwired iLIVING fans. The steel housing and automatic louvers suit a wall opening where some protection from moisture and debris is useful.
Its main compromise is control: this is a single-speed fan, unlike the ten-speed VEVOR 12-inch model, and the controller and power plug are listed as sold separately. The product data also describes a pre-wired cord, so buyers should confirm the supplied connection and included accessories before installation. At 65 dB, it is not silent, and its 11.8 lb weight merits a secure mounting surface.
Pros:- 2,438 CFM provides more airflow than the iLIVING 12-Inch fan.
- Rain-guard shutters help shield the opening from moisture and debris when the fan is off.
- Pre-wired power cord may simplify installation compared with hardwired alternatives.
- Steel housing is suited to a wall-mounted exhaust role.
Cons:- Single-speed operation offers less control than the ten-speed VEVOR 12-inch model.
- Speed controller and power plug are listed as sold separately.
- Listed 65 dB noise level and 11.8 lb weight call for attention to placement and mounting.
Best for: Greenhouse owners needing mid-to-high exhaust capacity and a wall-mounted unit with a pre-wired cord, without requiring multiple fan speeds.
Not ideal for: Buyers who need thermostat or humidity automation, multiple speed choices, or a ready-to-use setup without checking controller and plug compatibility.
- Blade size:16 inches
- Airflow capacity:2,438 CFM
- Voltage:120 V
- Power:115 W
- Motor:AC motor
- Speed control:Single speed
- Noise level:65 dB
- Mounting type:Wall mount
- Weight:11.8 lb
Our verdict“Choose this for strong, straightforward wall exhaust when one speed is enough and you have confirmed the required electrical accessories.”
iLIVING 18″ Wall Mounted Shutter Exhaust Fan with Automatic Shutter, Thermostat and Variable Speed Controller – Silver (ILG8SF18V-ST)
The iLIVING 18-inch is the strongest fit here for a large greenhouse that needs substantial exhaust capacity: its 1,736 CFM rating and thermostat-controlled variable speed let growers adjust ventilation as conditions change. Compared with the smaller VEVOR 10-inch, it is built to move much more air across a broad growing space, rather than serve a compact room or localized area. Its automatic shutter closes when the fan stops, while galvanized steel construction and aluminum blades suit regular ventilation duty. The tradeoff is its size and wall-mount installation, which call for a suitable opening and careful planning. At up to 65 dB, it is also less appropriate near quiet work or living areas, and the product data specifies indoor use.
Pros:- 1,736 CFM airflow suits larger greenhouse spaces.
- Thermostat and variable-speed control allow airflow to respond to heat.
- Automatic shutter closes when the fan is off.
- Galvanized steel frame and aluminum blades are suited to regular ventilation.
Cons:- Wall installation and the large fan opening require space and planning.
- Noise can reach 65 dB, which may be intrusive in quiet areas.
- Listed for indoor use, limiting suitability for exposed outdoor installations.
Best for: Growers with a large, enclosed greenhouse who need thermostat-led exhaust and enough airflow for broad heat management.
Not ideal for: Owners of small greenhouses, quiet growing rooms, or outdoor-exposed installations; this unit is large, can be audible, and is listed for indoor use.
- Airflow:1,736 CFM
- Fan diameter:18 inches
- Motor:Brushless
- Control:Thermospeed™ thermostat and variable speed
- Thermostat range:32–130 °F
- Power:97 W, 115 V
- Noise level:Up to 65 dB
- Mounting:Wall mount with automatic shutter
Our verdict“Choose this iLIVING model for a large indoor greenhouse needing high exhaust capacity and thermostat control, but not for a compact or quiet space.”
VEVOR 14-Inch Wall-Mounted Attic Exhaust Fan with Variable Speed, Temperature & Humidity Control, 2000 CFM, Automatic Shutter
The VEVOR 14-inch earns its place for greenhouse owners who want ventilation to respond to both heat and moisture. Its controller offers temperature and humidity triggers, ten speed settings, and a timer, giving more adjustment options than the thermostat-focused iLIVING 18-inch. The stated 2,000 CFM is a strong airflow figure for a 14-inch unit, useful when warm, humid air needs to be cleared quickly. An automatic shutter helps close the wall opening when ventilation is idle. Those controls add flexibility, but the listed noise level is 68 dB, so this is not the quietest choice for a greenhouse beside a home or work area. Wall installation also takes more planning than a clip-on circulation fan.
Pros:- Temperature and humidity triggers support responsive greenhouse exhaust.
- Ten speed settings and a timer provide a wide range of control.
- 2,000 CFM rating supports rapid air removal.
- Automatic shutter closes the vent when the fan is off.
Cons:- The stated 68 dB noise level may be noticeable in nearby quiet spaces.
- Wall-mounted installation requires a suitable opening and secure fitting.
- More automated controls may be unnecessary for growers seeking a simple fan.
Best for: Greenhouse growers managing both heat and humidity who want automated triggers, timed operation, and multiple speed choices.
Not ideal for: Growers prioritizing quiet operation or needing a fan that can be installed without making a wall opening; its stated 68 dB and wall-mount design may not fit.
- Airflow:2,000 CFM
- Fan diameter:14 inches
- Motor:Brushless EC
- Control:Temperature and humidity control, timer, push-button and touch control
- Speed settings:10
- Power:80 W, 120 V
- Noise level:68 dB
- Mounting:Wall mounted with automatic shutter
Our verdict“Pick the VEVOR 14-inch when temperature and humidity automation matter more than quiet running or a simple installation.”
Amico 12-Inch Shutter Exhaust Fan with Thermostat and 8-Speed Control
The Amico balances useful exhaust capacity with a lower stated noise level, making it a strong option for growers who want a wall fan without the louder profile of the VEVOR 14-inch. It moves 1,282 CFM and offers eight speeds plus thermostat control, so airflow can be adjusted rather than left at one fixed rate. The 25 W brushless motor and automatic shutters add practical greenhouse features, while the pre-wired 120 V plug can simplify the electrical connection when the installation location supports it. Its smaller airflow rating makes it less suited to large spaces than the iLIVING 18-inch. I would also treat its coverage claims cautiously: the supplied information gives conflicting area figures, so sizing should be based on airflow and greenhouse needs instead.
Pros:- Eight speed settings allow airflow to be adjusted to changing conditions.
- Thermostat supports automatic operation.
- Stated 50 dB noise level is lower than the VEVOR 14-inch’s listed 68 dB.
- Pre-wired 120 V plug can simplify connection, subject to the installation setup.
Cons:- 1,282 CFM is less suited to large greenhouses than higher-capacity wall fans.
- Coverage-area information is inconsistent in the supplied product details.
- Wall mounting still requires a suitable opening and secure installation.
Best for: Small-to-medium greenhouse growers who want thermostat control, several speed choices, and a quieter stated noise level.
Not ideal for: Owners of large greenhouses who need the higher exhaust capacity of the iLIVING 18-inch, or buyers relying on a single confirmed coverage-area figure.
- Airflow:1,282 CFM
- Fan diameter:12 inches
- Motor:25 W brushless DC
- Control:Thermostat and touch control
- Speed settings:8
- Noise level:50 dB
- Voltage:120 V
- Construction:Galvanized steel frame and aluminum blades
- Warranty:3-year limited coverage
Our verdict“Choose the Amico for adjustable, comparatively quiet exhaust in a smaller greenhouse, but size it by airflow rather than its conflicting coverage claims.”
VEVOR 10-Inch Wall-Mounted Exhaust Fan with Variable Speed Controller
For a smaller greenhouse with a wall opening already available, the VEVOR 10-inch offers straightforward exhaust in a compact format. Its 900 CFM capacity is below the Amico 12-inch’s 1,282 CFM, but that lower output may be a better match for a modest growing space where a larger fan would be excessive. Variable-speed control gives growers a way to tune ventilation, and the automatic shutters close when the unit is idle to help block rain and debris. Compared with the 5-inch Dual Grow Tent Fan, this is a wall exhaust fan that removes air rather than circulating it around plants. The tradeoff is a less feature-rich setup: the supplied details specify neither thermostat nor humidity-triggered automation.
Pros:- 900 CFM suits smaller greenhouse exhaust needs.
- Variable-speed control lets growers adjust airflow.
- Automatic shutters help block rain and debris while the fan is off.
- Alloy-steel construction and a compact 10-inch format suit wall installation.
Cons:- Lower airflow than the Amico 12-inch and larger exhaust fans in the roundup.
- No thermostat or humidity-triggered control is listed.
- Wall mounting requires a suitable opening and installation work.
Best for: Owners of compact greenhouses who need a wall-mounted exhaust fan with adjustable speed and an automatic shutter.
Not ideal for: Growers of large or especially humid greenhouses who need higher airflow or automatic temperature and humidity triggers.
- Airflow:900 CFM
- Fan diameter:10 inches
- Motor:AC, 45 W
- Motor speed:1,650 RPM
- Voltage:120 V
- Noise level:50 dB
- Control:Variable speed
- Mounting:Wall mount with automatic shutters
- Dimensions:12.8 × 12.8 × 7.09 inches
Our verdict“Choose this VEVOR for compact, manually adjusted wall exhaust, but step up to a higher-capacity model for a large greenhouse.”
5-inch Dual Grow Tent Fan – Adjustable Tilt, 3 Speeds, IP54 Waterproof, Includes 8 ft Cord & Power Adapter
This dual-fan setup serves a different greenhouse job from the wall-mounted exhaust models: it circulates air around plants rather than drawing a large volume out of the structure. The two adjustable-tilt heads can aim airflow where foliage needs it, and the clamp fits poles from 0.5 to 2 inches, making placement flexible in a grow tent or compact greenhouse. Its 330 CFM is far below the VEVOR 10-inch’s 900 CFM, so it should not be treated as a replacement for an exhaust fan when heat or humidity needs to leave the space. The IP54 rating adds protection against dust and splashes, while three speeds keep control simple. At maximum output, noise may be more apparent than at its quieter low setting.
Pros:- Two adjustable fans can direct airflow to separate areas without oscillation.
- Clamp mount fits poles from 0.5 to 2 inches.
- IP54 protection suits environments with dust and occasional splashes.
- Brushless motor is rated for up to 67,000 hours of life.
Cons:- 330 CFM is not comparable to the exhaust capacity of wall-mounted greenhouse fans.
- Three speed settings offer fewer adjustments than the Amico 12-inch’s eight.
- Maximum noise may be noticeable in a quiet growing space.
Best for: Grow-tent and small-greenhouse growers who need adjustable, localized circulation around plants and have a pole or frame for the clamp.
Not ideal for: Growers who need to exhaust hot, humid air from a greenhouse; its 330 CFM circulation airflow is much lower than the VEVOR 10-inch wall exhaust.
- Airflow:330 CFM
- Fan size:5 inches, dual-fan system
- Motor:Brushless DC
- Speed settings:3
- Power:6 W
- Noise level:45 dB listed; as low as 37 dBA at lower speeds
- Mounting:Clip-on; fits 0.5–2-inch poles
- Protection:IP54
- Dimensions:4 in D × 5.6 in W × 5.6 in H
Our verdict“Choose this dual fan to circulate air around plants in a tent or small greenhouse, not as the main means of greenhouse exhaust.”
iLIVING 16-Inch Wall-Mounted Shutter Exhaust Fan with Thermostat and Variable Speed Controller
The iLIVING is a strong fit for growers who want a larger greenhouse exhaust fan with familiar, direct controls rather than a complex automation setup. Its 1,200 CFM airflow, thermostat, and three speed settings let you adjust ventilation as conditions change, while automatic shutters close when the fan is off. Compared with the smaller Windigaga 8-Inch, it is better suited to moving air through a larger space, but it lacks that model’s remote and timer. The galvanized steel frame and aluminum blades suit regular use, and UL/cUL listing adds a useful installation credential. The tradeoff is a listed noise level of up to 65 dB, plus the need for a wall opening and wall-mounted installation.
Pros:- Thermostat and three speed settings support adjustable, temperature-responsive ventilation.
- Up to 1,200 CFM suits larger spaces than compact options such as the Windigaga 8-Inch.
- Galvanized steel frame and aluminum blades are suited to regular operation.
- UL and cUL listed, with OSHA-compliant wire guards noted in the product information.
Cons:- Noise is listed at up to 65 dB, which may be intrusive in a quiet greenhouse or nearby room.
- Wall mounting requires a correctly sized opening and a suitable installation location.
- No remote or timer is specified.
Best for: Greenhouse owners with a suitable wall opening who want thermostat-based ventilation and three manual speed choices for a medium-to-large growing space.
Not ideal for: Growers who need a quiet fan near living areas or want remote operation, a timer, or a non-wall-mounted option.
- Fan diameter:16 inches
- Airflow capacity:Up to 1,200 CFM
- Coverage area:Up to 1,800 sq. ft.
- Speed settings:3
- Temperature control range:32–130°F
- Power:97 W
- Voltage:115 V
- Noise level:Up to 65 dB
- Mounting and materials:Wall mount; galvanized steel frame and aluminum blades
Our verdict“Choose this iLIVING when you want a wall-mounted greenhouse fan with thermostat control and stronger airflow than a compact model, and can accept its noise and fixed installation.”
12 in Shutter Exhaust Fan Wall-Mount Automatic Louvers Variable Speed, Sturdy Steel Housing, Low Noise, AC Motor, 1347 CFM Ventilation and Cooling for Attic, Garage, Barn, Greenhouse, Workshop
This VEVOR is the straightforward pick for growers who want a shuttered wall fan without the thermostat and humidity controls found on the VEVOR 16-Inch Wall-Mounted Exhaust Fan. Its description advertises up to 1,347 CFM, though the listed airflow capacity is 1,100 CFM; I would treat that discrepancy as a reason to verify the expected airflow for your setup rather than plan around the higher figure. The stated 60 dB noise level is lower than the iLIVING 16-Inch’s listed maximum, which may suit a work area where fan noise matters. A prewired cord and button control can simplify setup, but this remains a wall-mounted unit, and its 12-inch format and basic controls offer less flexibility than models with thermostats or remote controls.
Pros:- Rain-guard shutters help shield the opening when the fan is off.
- Stated 60 dB operation is quieter on paper than the iLIVING 16-Inch’s up-to-65 dB figure.
- Prewired power cord and button control support a simpler setup.
- Steel housing is suited to regular ventilation use.
Cons:- Airflow is inconsistent across the product data: 1,100 CFM in the specifications and up to 1,347 CFM in the description.
- Button control lacks the thermostat and humidity automation on the VEVOR 16-Inch.
- Wall mounting still requires a suitable opening and secure installation.
Best for: Greenhouse owners seeking a wall-mounted shutter fan with simple button operation and a stated noise level below that of the iLIVING 16-Inch.
Not ideal for: Buyers who need dependable, clearly specified airflow figures or automatic temperature and humidity control.
- Fan size:12 inches
- Airflow capacity:1,100 CFM listed; up to 1,347 CFM advertised
- Noise level:60 dB
- Power:58 W
- Voltage:120 V
- Motor:AC, 1,600 RPM
- Control:Button control
- Housing:Alloy steel with rain-guard shutters
- Mounting:Wall mount
Our verdict“Pick this VEVOR for comparatively simple, quieter-on-paper wall ventilation, but confirm its airflow rating before sizing it for your greenhouse.”
VEVOR 16-Inch Wall-Mounted Exhaust Fan with Variable Speed and Temperature & Humidity Control
Among these five, this VEVOR offers the broadest control package for a greenhouse where both heat and humidity need active management. Its temperature and humidity controls, 10 speed settings, multiple modes, and timer give growers more ways to tailor exhaust than the thermostat-only iLIVING 16-Inch. The EC motor is listed at 98 W, while the advertised airflow reaches 3,000 CFM; the specifications instead state 2,900 CFM, so I would not size a greenhouse around the higher number without checking. That output and feature set make it a better fit for a larger, more demanding space than the Windigaga 8-Inch, but the listed 70 dB noise level is the loudest stated figure in this group. Its 240 V requirement also narrows installation options.
Pros:- Temperature and humidity controls offer broader environmental response than the iLIVING 16-Inch thermostat.
- Ten speed settings, multiple modes, and a timer provide fine control over ventilation.
- Metal housing and shutters that close when the fan is off suit a permanent wall installation.
- Listed airflow of 2,900 CFM, with the description advertising up to 3,000 CFM.
Cons:- Airflow figures differ between the specifications and product description.
- The listed 70 dB noise level may be disruptive in a quiet greenhouse.
- The 240 V supply may require electrical work or may not match an existing greenhouse circuit.
Best for: Growers with a larger greenhouse, a compatible 240 V supply, and a need to automate exhaust around both temperature and humidity.
Not ideal for: Small greenhouse owners, buyers on standard 120 V wiring, or anyone prioritizing low operating noise and simple installation.
- Blade diameter:16 inches
- Airflow capacity:2,900 CFM in specifications; 3,000 CFM advertised
- Motor:EC, 1,400 RPM
- Power:98 W
- Voltage:240 V
- Speed settings:10
- Controls:Temperature and humidity control, multiple modes, and timer
- Noise level:70 dB
- Mounting and weight:Wall mount; 15 lb
Our verdict“Choose this VEVOR for extensive environmental controls and high stated airflow when your greenhouse can support its 240 V supply and noise level.”
Windigaga 8-Inch Shutter Exhaust Fan with Thermostat and Remote, 760 CFM
The Windigaga makes sense when a greenhouse needs targeted exhaust but cannot justify the size or airflow of the 16-inch iLIVING and VEVOR models. Its 760 CFM output is paired with thermostat-based automatic operation, three speeds, an 18-hour timer, and a remote, giving it more convenient controls than the basic button-operated VEVOR 12-Inch. At a stated 40 dB and 26 W, it is also the quietest and lowest-power option in this group on the supplied figures. That compactness comes with a clear limit: an 8-inch fan may not exchange enough air for a large or densely planted greenhouse. Wall mounting requires a cutout, and the included cable lengths can affect where the controller and fan can sit.
Pros:- Thermostat, remote, three speeds, and an 18-hour timer give it more control options than the VEVOR 12-Inch button model.
- Listed 40 dB noise level and 26 W motor suit spaces where noise and power draw matter.
- Automatic shutters help block rain, dust, wind, and pests when the fan is off.
- 760 CFM offers useful exhaust capacity in a compact 8-inch format.
Cons:- The 8-inch fan and 760 CFM output may be insufficient for larger greenhouses.

Our verdict“Choose the Windigaga for a small greenhouse where quiet, remote-controlled thermostat operation matters more than maximum airflow.”
Amico 10″ Shutter Exhaust Fan, Remote 9-Speed 13W DC Motor, 1000 CFM
The Amico is the compact choice for growers who want more speed adjustment than the Windigaga 8-Inch without stepping up to a larger, more power-hungry exhaust fan. Its 13 W DC motor is paired with a stated 1,000 CFM and nine remote-controlled speeds, making it easier to tune airflow than the Windigaga’s three settings. The product claims up to 76% lower electricity use, but that comparison is not detailed in the supplied data, so the more concrete draw is its listed wattage. At 42 dB, it is slightly louder on paper than the Windigaga, and it does not list thermostat control; growers seeking automatic temperature response may prefer that model or the iLIVING 16-Inch. The Amico’s 8-hour timer and plug-in installation keep operation convenient, but the remote is central to its controls.
Pros:- Listed 13 W draw is lower than the 26 W Windigaga 8-Inch motor.
- Nine speed settings allow finer airflow adjustment than the Windigaga’s three speeds.
- Remote control and an 8-hour timer support convenient operation.
- Stated 1,000 CFM exceeds the Windigaga’s 760 CFM output.
Cons:- No thermostat or humidity control is specified, unlike the Windigaga and larger automated models.
- Remote-dependent operation may be inconvenient if the remote is misplaced.
- The 10-inch format may not provide enough exhaust for a large greenhouse.
Best for: Small- to medium-greenhouse growers who want adjustable remote airflow with a low-wattage motor and a standard 120 V outlet.
Not ideal for: Buyers who need thermostat automation, direct controls on the fan, or a unit for a large greenhouse with high air-exchange demands.

Our verdict“Choose the Amico when low listed wattage and nine remote speed settings matter more than thermostat automation or large-space airflow.”
How We Picked
I compared these 15 greenhouse ventilation fan options by their stated role and buyer-facing differences: exhaust versus circulation, fan size, published airflow where provided, automatic shutters, and control options such as thermostats, variable speed, temperature and humidity control, or remote operation. I also weighed practical fit: whether a model appears aimed at a compact grow space or a larger wall opening, and how much setup and operating control it asks of the buyer. A circulation fan can help distribute air, but I did not treat it as equivalent to an exhaust fan.
The ranking favors useful ventilation capability paired with workable control, rather than the largest advertised airflow alone. The iLIVING 20-Inch leads for its combination of larger format and thermostat/variable-speed control; VEVOR’s controlled models rank well for added environmental inputs. Smaller remote or compact units suit narrower needs, while basic or circulation-focused picks rank lower for buyers seeking whole-greenhouse air exchange. Product specifications supplied for this roundup vary, so I recommend verifying opening size, electrical requirements, and installation details before choosing.
Factors to Consider When Choosing Greenhouse Ventilation Fans
Before choosing a model, match the fan to the greenhouse’s ventilation job—not simply its diameter or headline airflow. I would start with the structure, then decide how much automation and air movement the plants need.
Size airflow to the greenhouse and its replacement-air path
A fan can only exhaust air effectively if outside air has a clear route into the greenhouse. Before buying, estimate the growing area and ceiling height, then check the manufacturer’s airflow guidance for the actual installation rather than relying on a bare CFM figure. Screens, louvers, long ducts, and restrictive openings can reduce delivered airflow. A common mistake is to install a powerful exhaust fan in a tightly sealed space without adding intake openings. That can limit performance and create uneven air movement. For a larger structure, several appropriately placed fans may distribute ventilation better than one oversized unit, depending on the layout.
Choose exhaust or circulation based on the problem
An exhaust fan pulls warm, humid air out and supports air exchange when fresh air can enter elsewhere. A circulation fan moves air around inside the greenhouse, helping reduce stagnant pockets without replacing the air itself. These jobs are complementary, not interchangeable. The VIVOSUN AeroWave E6 and 5-inch dual fan in this roundup are circulation-oriented options, so they make more sense as additions or for compact grow areas than as a sole ventilation system. If heat buildup or humidity removal is the main concern, prioritize an exhaust fan first. If exhaust is already handled but plants experience still air, circulation may be the more relevant addition.
Decide how much automation you will actually use
Thermostat control can switch a fan in response to temperature, while variable-speed control lets you tune airflow rather than relying only on on/off operation. Models with temperature and humidity control add another way to respond to greenhouse conditions, and remote controls can make adjustments easier when a fan is mounted high or out of reach. These features can improve day-to-day management, but they also add controls to configure and maintain. Think about whether your growing routine benefits from automatic responses or whether a simpler manual setup is enough. Do not assume that a listed controller includes every sensor or scheduling feature you want; check the supplied components and operating instructions.
Measure the opening and plan the installation before ordering
Fan diameter is not the same as the required wall cutout or mounting footprint. Measure the intended opening and available wall space, and check whether the greenhouse frame and cladding can support the selected unit. Shutter-style fans need room for the louvers to open freely, while mounting height and nearby structures can affect airflow. Also check the electrical supply, cord reach, weather exposure, and whether the product is intended for the conditions where it will be installed. A frequent buying error is selecting a fan by airflow alone, then finding that the wall, wiring, or opening needs changes. Confirm installation requirements before treating any model as a direct fit.
Balance noise, operating time, and maintenance
A fan that runs for long periods affects the greenhouse’s sound level and maintenance routine, particularly near a home or work area. Compare noise information where the manufacturer provides it, but treat conditions and installation as part of the result: vibration, mounting surfaces, and obstructions can change perceived noise. Shutters and guards may collect dust or debris, so plan access for cleaning and inspection. Greenhouse humidity and exposure also make suitable placement and electrical protection important. Paying for variable speed may be worthwhile if it helps avoid running at full output when conditions are mild. If the fan is difficult to reach, favor a setup that is easier to control and service safely.
Pay for features that solve your specific growing conditions
A larger fan or more elaborate controller is not automatically the better purchase for every greenhouse. A compact space may need a smaller exhaust unit, while a larger or hotter structure may need more capacity and a separate intake plan. Added humidity control is most useful when moisture management is part of the recurring problem; remote operation matters more when the fan is mounted beyond easy reach. For a beginner, straightforward installation and controls may be more valuable than several modes that go unused. I would spend extra only when a feature addresses a defined need, such as more precise speed adjustment or environmental response. Compare the full setup requirements—not just the fan—before deciding where to put the budget.
Frequently Asked Questions
Can a grow tent clip fan ventilate a whole greenhouse?
Usually, a clip fan is intended to circulate air within a small growing area, not exhaust greenhouse air outdoors. In this roundup, the VIVOSUN AeroWave E6 and the 5-inch dual fan fit that circulation role. If heat and humidity need to leave the structure, pair circulation with an appropriately sized exhaust fan and a route for replacement air. A clip fan may still help reduce stagnant spots, but it should not be counted as the greenhouse’s only ventilation. Check the product’s stated use and mounting range before relying on it for a larger space.
Should I choose a larger fan or a fan with more control options?
Start with the greenhouse’s airflow requirement and installation limits, then compare controls among models that can meet that need. A larger fan may suit a bigger space, but its opening and mounting requirements can rule it out. Variable speed or environmental controls can help manage changing conditions, yet they cannot compensate for an undersized fan or a blocked intake. The VEVOR controlled models offer temperature and humidity control, while several iLIVING options combine thermostat and variable-speed control. Match capacity first, then pay for the control method you are likely to use.
Do I need an intake vent if I install an exhaust fan?
Yes, an exhaust fan needs a path for fresh air to enter the greenhouse. Without enough intake area, the fan may struggle to move air and ventilation can become uneven. Plan intake openings so incoming air can travel through the growing space rather than short-circuiting directly to the exhaust. Screens and louvers can restrict airflow, so their effect belongs in the layout decision. Follow the fan maker’s installation guidance and consider the structure’s local weather and pest-control needs when placing intakes.
Is humidity control worth choosing over thermostat control alone?
It depends on which condition is driving your ventilation decisions. Thermostat control responds to temperature, while a temperature-and-humidity controller can also react to moisture levels. If humidity is a recurring concern, the added input may be useful; if heat is the main issue and you prefer a simpler setup, a thermostat-based model may be enough. The VEVOR 14-inch and controlled 16-inch models are among the listed options with temperature and humidity control. Check how the controller operates and what sensors are included before relying on it for automatic management.
How should I compare advertised CFM figures between these fans?
Use CFM as one comparison point, not a promise of the airflow you will get after installation. The mounting opening, shutters, intake arrangement, obstructions, and any ducting can affect delivered airflow. A fan with a higher stated figure may also require a larger opening or suit a different greenhouse scale. Compare figures only alongside the manufacturer’s specifications and the installation conditions they describe. If the product listing does not provide comparable test details, treat the numbers as directional and focus on fit, controls, and the complete ventilation plan.
Conclusion
For one main wall-mounted exhaust fan, I would choose the iLIVING 20-Inch as best overall when the greenhouse can accommodate its larger format. My best value direction is the VEVOR 14-Inch for buyers who want temperature and humidity control in a more compact size, while the best premium-style feature set goes to the VEVOR controlled 16-Inch for growers prioritizing added environmental management. For beginners, the iLIVING 12-Inch offers a more approachable starting point than jumping to a large fan, provided its capacity suits the structure. For compact or specific needs, consider the Amico 10-Inch remote model for remote operation, the Windigaga 8-Inch for a smaller shutter-fan setup, or a VIVOSUN or 5-inch dual fan when the task is internal circulation rather than exhaust. Before ordering, verify airflow needs, opening dimensions, intake placement, and electrical requirements so the model fits the greenhouse as well as the job.
