Fans & Blowers

Fans and blowers are an integral part of any ventilation system. In order to maintain a healthy environment while eliminating odors, growers will implement exhaust fans and intake fans, to bring in clean air while removing impure air.

Why do you need fans in the grow room?

The most simple of ventilation systems will include an intake and exhaust fan. These are necessary for exchanging the air in the grow room or grow tent, which we want to do every 3 minutes at least.

This is a good start, but to truly get the most out of your ventilation system you should implement at least another fan for circulating air in the room or tent. Using fans will reduce cold and hot spots in the room, bring the temperature down, and distribute CO2 more evenly. A constant breeze on your plants also strengthens stems, and reduces the risk of pests.

Some of the best options for circulating air include wall mount fans, oscillating fans, and floor & pedestal fans. These are great options for grow rooms with lots of space, but if you are tight on room you can use clip-on fans! These are great space saving options.

Our inline fans are great for pairing with an air-cooled reflector or a carbon filter, and we carry a range of sizes to fit whatever equipment you have!

Do you need a fan in a grow tent?

You could argue it is even more important to use fans and blowers in a grow tent, since this is a sealed environment and is less likely to have air flow through it than a grow room. Since grow tents are generally smaller than grow rooms, clip-on fans are a perfect option for circulating air in your grow tent.

How do I calculate CFM for my grow room?

To measure CFM, or cubic feet per minute, you will need to multiply your room’s length x width x height. For example, if your grow tent is 4’ x 4’ x 8’, you are working with 128 cubic feet. Therefore, a fan with a CFM of 128 will recirculate the room with fresh air in about a minute. We recommend getting a fan slightly larger than the CFM necessary for your room, to ensure you are adequately replacing the air in your indoor garden.
