What are the best fans for growing pot? The top 10 fans for growing pot are the AC Infinity Cloudline, TerraBloom 6″ Inline Fan, Vivosun 6, Can Fan Pro Series, Active Air, iPower, Vortex 347, Hurricane Inline Fans, Tjerlund M-6, and VIVOSUN Oscillating Fan.
This post is about the best brands for space ventilation. The fans below come in a wide variety of sizes that will carry your operation to a higher level.
Importance of Ventilation for Growing Pot
Pot plants need fresh air for two reasons:
Plants need fresh air to fuel the method of photosynthesis. Photosynthesis will allow them to convert ambient light, water, and carbon dioxide into food.
Plants breathe to convert glucose and oxygen from photosynthesis to energy. This is the only way to fuel their growth.
Without fresh air, your pot plants will starve to death. However, before this occurs, a breeding ground will be created for viruses and pests. Without adequate ventilation, stale, warm air will pile up around your plants.
Inadequate ventilation causes a moist, humid atmosphere. Many pests and plagues enjoy this sort of atmosphere.
Things to Consider Before Buying a Grow Fan
Pot plants consume all the CO2 available around them within a minute. For this reason, you need to set up fans near your plants.
Fans disperse any fresh air around the growing room. For this reason, all the plants should have access to a continuous stream of CO2.
Growing pot indoors is very relaxing. Yet, monitoring the volume of light, temperature, and humidity is a struggle. Fortunately, you don’t have to deal with room temperatures when you buy the right ventilation.
Best Grow Fans You Can Find
See below for a thorough evaluation of each of the growing tent fans.
AC Infinity CLOUDLINE T6 6” Inline Duct Fan
The new CLOUDLINE series features a state-of-the-art EC motor. It uses reliable electronic pulses with smart programming to control the speed of the fan. This results in a 40% noise reduction over traditional AC duct fans.
Voltage suppression reduces fan speed, which produces increased engine noise and heat. Each system uses a DC or EC engine powered by Pulse Width Modulation. This enables them to work more quietly and save more energy than AC fans.
It also includes an integrated temperature sensor that regulates the speed of the fan. It is ingress-protected from dust and liquids.
The full package includes an inline fan unit, controller, user manual, and everything you need for installing the fan and powering it through the outlet.
The fans sustain the greatest output in high-static pressure conditions.
TerraBloom 6″ Inline Fan
This 6-inch fan comes with a CFM rating of 395, which allows for proper intake or outflow of air in a standard grow tent.
The speed controller shows three configurations: low, medium, and high. It encourages you to reduce the flow of air and the amount of noise and energy bills.
The materials are made from ABS plastic. This inline fan comes in three sections, with a removable central part. This results in quick washing and repairs. To detach it, pop the buckles and rotate the center piece at an angle of 30 degrees.
TerraBloom, while not as feature-rich as AC Infinity’s Cloudline, is still durable. It is a cheap option if you are okay with a few fewer features to regulate your airflow.
This fan can work at temperatures of up to 140 degrees Fahrenheit and includes thermal protection. If your growing room hits 130 degrees Fahrenheit, the fan shuts down immediately.
VIVOSUN 6-Inch 390 CFM Inline Duct Fan
Vivosun is popular for making world-leading room fans and filters. While other inline fans are more universal, Vivosun is the best when it comes to hydroponic goods.
The Vivosun 4-Inch 190 CFM fan is a heavy-duty blower with a fan speed of 2300 rpm. The airflow travels quickly to your particular position for optimal ventilation.
The Vivosun 6 is an energy-efficient and quiet operation. It is super easy to mount because of its light weight. Balanced blades are suitable for improving the air supply and ventilation of exhaust air.
Another nice thing about the Vivosun 6 is that it is built for full power with low noise.
Can Fan Pro Series 420 CFM Max Fan, 6″
You can keep warm places colder with the Can-Fan 736746 Max Fan Pro Series 6-inch CFM 420. The fan automatically props up on its own, and it can function as a stand-alone.
You can also install it with the in-line of your existing ductwork to improve airflow. The sturdy housing blends with the surroundings, while the gentle breeze does not topple or damage planters and containers.
It includes high-speed ventilation with 420 CFM, which means it can transfer air and ventilate indoor areas quicker. This prevents your hydroponic garden from getting too warm.
You can install inline booster fans to maximize air pressure with the current ductwork.
Quiet-running, it requires a 120V power cord and 420 CFM plug. Requiring just 69 watts of electricity, this fan will save you from high energy bills.
Several fan blades rotate the air to create enough ventilation to reduce stuffiness and keep the air cleaner.
Hydrofarm Active Air Inline Fans
Active Air is another brand for inline hydroponics enthusiasts. It sells 4′′, 6′′, 8′′, 10′′, and 12′′ versions. This brand is known for its reliability, versatility, and outstanding style.
The fans have ceramic coatings to avoid metal corrosion and deterioration. It contains the appropriate mounting brackets and hardware.
If you are growing a lot of weed and want to grow op properly, you need to get professional-quality equipment.
Active Air inline fans will certainly fulfill the criteria. Active Air fans don’t come with a built-in speed controller, so you’ll need to buy one separately.
iPower 6-Inch Inline Fan w/ Carbon Filter, Ducting, & Speed Controller
The iPower 6-Inch Grow Tent Fan is made of UL quality components for quiet work. There are composite fan blades and a central hub that eliminates noise and vibration. It comes equipped with a 6-Inch 1050+ IAV Australia Charcoal Filter.
This fan is one of the most absorbent carbon filters available. It also contains 25 feet of uninsulated aluminum duct + 2 stainless clamps. There is a control switch with variable speed settings: OFF, HIGH, MED, LOW.
A free pre-filter is included. It is best to replace the pre-filter every six months to secure the filter.
An iPower combination has everything you want. The price and versatility of an all-in-one kit make it a decent choice.
Vortex 347 CFM S Line S-600 Fan
This fan comes with fantastic features, all of which are crafted to improve its performance. Like most quality fans, the Vortex 347 CFM Line S-600 fan comes with a user manual, which will help you mount it quickly and seamlessly.
It has double insulated walls, an energy-efficient AC motor, and a silencer. The silencer minimizes the sound it emits along with the other features.
It generates a wind vortex to make the air travel longer distances than bigger diameter fans with non-tapered holes.
Hurricane Inline Fans
Hurricane inline fans are unusual because they come in not three sizes but five. Hurricane fans vary from four-inch to 12-inch capacities. If you have a wide operation that requires many airflows, this is the brand for you.
All Hurricane fans have mounting brackets with easy-to-follow assembly directions. The steel housings of all the fans are powder-coated with an elegant matte black finish.
The coating can avoid corrosion in damp growing space conditions.
Tjerlund M-6 Inline Fans
Tjernlund inline fans deliver top-of-the-line quality for mid-size growing operations.
They have been around since the 1930s. The company concentrates on developing rooftop heating and cooling devices. It sells 4′′, 6′′, 8′′, and 10′′ fans with and without variable speed controllers.
Depending on your lighting, these fans could be used for any size of grow room, from small to extra-big. The thing that sets Tjernlund apart is that its fans are particularly strong.
For example, its six-inch model is 460 CFM, meaning it can be used for medium growing operations and larger-sized growing ops.
VIVOSUN Clip-On Oscillating Fan
You can install this growing tent oscillating fan on the wall or place it on a tent frame. This fan is flexible and handy. It will ensure detailed circulation of the air within the room.
The fan is powerful and easy to use. Thus, it’s preferred for indoor gardening. For indoor grow activities, you don’t need to drive through hundreds of cubic feet of air.
These oscillating fans keep the air flowing, which is why you don’t need crazy-strength blade size/fan diameters.
Understanding Grow Room Fans
Now that you know the best-growing fans, let’s get through the specifics of what a growing fan is. There are a few more things you should know before you make your choice.
Grow Room Fan Types and Sizes
Several fans exist, each serving a certain function. Purchasing a fan without understanding the features of each will leave you wishing you’d done more research. Below are the five main fan styles.
- Oscillating Fans
- Inline Fans
- Outtake or Exhaust Fans
- Booster Fans
- Intake Fans
There are many factors to consider when choosing the right fan for your grow tent. Strong oscillating fans may be used in a big grow space to increase air coverage over a wide area.
This is not possible in a small grow tent, where clip-on fans attached to a pole are a safer choice.
The typical sizes for clip fans used in grow tents are six inches and eight inches. Go for the greater size. Bear in mind that it calculates the actual size of the grill and not the length of the fan blade.
Clip fans are cheap. They do not move air a lot, but they do the trick in a small to a medium-sized tent. They are also a perfect way to conserve energy.
Clips fans installed on tent poles will spin only in some directions. The angles are limited because the material itself can get in the way of the form of the clip and prohibit you from spinning it entirely.
Using many clip fans is a perfect over-the-clip option in a growing tent.
Oscillating Stand Fans
The bigger your growing space is, the bigger the solution you need. Oscillating fans come in many sizes, including 8′′, 10′′, 12′′, 16′′, 20′′, 24′′, and 30′′. The bulk of the larger sizes are available as stand fans.
Because they deliver air in several directions, they are a perfect option to ensure airflow. If you have a big room, go for it.
Big oscillating fans on stands operate well in wider tent settings. Many fans are required in larger spaces. If you are using a big growing tent, you probably want to read this guide on selecting the right tent fans.
At the same time, tower fans will provide circulation both above and below your pot. Many versions oscillate so that they can fill the whole tent.
They are a little more expensive than some of the cheaper tent fan options above. However, if they can cover double the field, you’ll need fewer fans, which offsets the cost.
Deciding on the Proper Grow Tent Fan Size and Power
The first questions you might be asking are: “What’s the right size of a grow tent fan?” and “What’s the right growing tent fan power?” Read the information below for a quick guide.
- When you replace the air in a grow space, the general rule of thumb is that you should replace all the air once per minute. It is the CFM ranking that you’ll read below.
- The exact fan diameter—four, six, or eight inches—will be calculated by the CFM (cubic feet per minute) rating. You will need to keep your tent cold, so think about the CFM ranking. You’ll find that most of the 200 CFM inline fans are four inches in diameter.
- Then make a few extra considerations, such as a 25% reduction in fan power when you install a carbon filter, as well as a 30% reduction in power per each 90-degree bend in your conduit.
There are two choices for putting a growing fan in your tent: either inside or outside. What’s the difference?
If you choose outside, the ventilator pulls the ventilation from your tent’s interior to the outside. This is done through a duct at the top corner of your tent.
If you want inside, you will need a fan and a vent if you use a filter. Hang it at the top of the tent where the hottest air flows naturally.
You are going to need hangers to hang your fan and filter from the inside ceiling of your growing tent. Not all fans include hangers, so make sure you’ve got them.
I find that it’s better to hang inside the shelter. The bottom of most growing tents has passive air intakes.
These are sharp openings that allow fresh air to flow into the tent. The fresh air is drawn in as the fan produces a low-pressure atmosphere within the tent.
Tips for Choosing a Fan
Inline fans are the perfect solution, particularly if you are using a growing tent. You can attach them directly to the current ducting or mount them as a spare part of the machinery.
They provide the most powerful and cost-effective way to cool down your growing room. Aside from that, they can be operated with variable speed controllers for various degrees of cooling.
Larger fans with larger CFMs should be used in larger grow rooms, particularly those with HID lighting. HID lights emit a lot more heat than LED lights, so more insulation is required to protect the plants from burning.
For this reason, a large growing room with LED lights will require less ventilation than a small room with HID lights. Always remember this when you are looking for inline fans.
One issue that new growers often ignore is ventilation. It is important to maintain a safe atmosphere within your growing field.
It doesn’t matter whether you are using a growing tent, a growing cabinet, or a warehouse; be sure to secure good ventilation.
