Top Rated Inline Fans For Cannabis Grow Rooms: 2017 Reviews, Guides and Coupons

To successfully grow cannabis in a grow room or tent, inline fans are vital. You can grow more seasons each year, with higher quality, when growing indoors, as long as you have the right equipment. Growing indoors properly also means the outside conditions don’t affect your grow space.

Inline fans are there to prevent your cannabis from burning. Growing lights produce heat which burn plants if not dealt with properly. Having the correct ventilation system expels CO2 and balances the humidity levels. Using inline fans gives you less to worry about and keeps your cannabis growing healthily. Be sure to check out our hugely popular article on the Best LED Grow Lights for Cannabis while you’re here. 

How Do You Pick The Correct Fan Size?

You need to figure out how large the size of your grow space is. An easy formula to use when picking the most suitable inline fan is this:

Length x width x height (feet) x 1.25 (125%)

The added 25% is there to provide you with a little extra room so things aren’t too tightly compacted. The number you have at the end of this equation is the amount of air that should be removed by the fan every single minute.

You also need to think about the type of lighting you’re using when determining which fan size to use. The more heat the light produces, the more heat there is to be dispersed. LEDs tend to create considerably less heat. But if you went with HID lights, you’d need a higher CFM fan due to a considerable amount of heat being produced.

So take a look at your growing space to help you decide which inline fan would be the best. We’ve compiled a list of the top inline fans to support cannabis growth in grow rooms and tents.
