Air circulation is one of the most important accessories to anyone's grow space. Air ventilation is the process of pulling in fresh cool air, while exhausting the heat and odor through a window vent, typically using an Active Carbon Filter. Too much heat in your grow tent can make your plants seem listless, weak, burn, and/or stunt the growth of your crop.
Your grow space is calculated in CFM's (Cubic Feet per Minute), which calculates Length x Width x Height to calculate the CFM's needed from your Wind Tunnel. It's NOT recommended to get a wind tunnel that exceeds your CFM calculation by more than 100cfm's or your plants can experience wind-burn and other detrimental effects from over-cooling. Regardless of who tells you; plants love heat just as much as the love light, but too much heat and too much light can also have damaging effects on their own, so it's important to get it as right as possible....that's why we're here to help!
For example: The recommended grow tent would be 4'W x 4'L x 7'H. To calculate the CFM's (Cubic Feet per Minute), you take 4x4x7= 112 Cubic Feet. Then we want to take our equation and multiply it by 3; to make sure we have positive air flow that keeps the plants happy and vents heat properly for 2 LED lights. We calculate @ 336CFM's which would indicate we need a 400CFM wind tunnel and carbon filter to do the job efficiently.
If you still can't figure it out, or if you wish to have someone calculate that for you - then we offer this useful tool to get you going right away! Grow Space CFM Calculator: https://www.phreshfilter.com/tools/cfm-calculator
