What size fan for 2x2 grow tent? 2020 Updated
What Is The Purpose Of A Small Grow Tent?
Basically, a small grow tent is an enclosed self-surviving structure that allows gardeners to grow plants indoors.
A micro marijuana grow tent enables an indoor gardener to have total control over environmental factors such as light, humidity, and temperature, which are all essential to a plant's development and yields.
Overall, a grow tent should be reflective, waterproof, light-proof, sturdy, and non-toxic. Also, it must be built with observation windows and multiple vents.
What Is the Importance of Growing Tent Ventilation?
When you have grow lights for weed, they will emit heat and this can alter the temperature inside the grow tent.
With ventilation in the indoor grow tent, you will be able to get rid of the excess heat that may be detrimental to the plants.
If the humidity is not controlled, then it means that your plants may not grow in a healthy manner. Ordinarily, plants will produce water vapor, which increases humidity. The ventilation system will control the humidity.
Calculating Fan Strength
Calculate the total volume of your grow room by multiplying the length x width x height. This is the cubic feet measurement of your room. Hold on to this number. Next, we are going to multiply it by the efficiency drop.
This efficiency varies based on the age and make of the filter and the length of the duct between the inline duct fan and filter, on top of an endless list of other factors. At the minimum, you want to multiply the volume of your room by 25%, but here is a good rule of thumb: if you have a long duct path, multiply it by three, and if you a short path multiply it by 2.
Your formula should look like this: Volume of room x efficiency drop = CFM
Most 2x2 tents measure 24in x 24 in x 64 in. So the total volume of air in a 2x2 grow tent is 2ft (length) x 2ft (width) x 5.33ft (height) = 21.6 cubic feet. But that doesn’t mean you need at least a 22 cfm fan.
When you consider a carbon filter reducing your fan efficiency by 25%, and one 90 degree duct bend reducing another 30%, a fan with 200 cfm will get reduced to ~100cfm (200cfm x 0.7 x 0.75).
