What Size Fan for a 4×4 Grow Tent
What Size Fan for a 4×4 Grow Tent? The size of the fan you will need for a 4×4 grow tent depends on several factors.
This includes the lights you are using and whether you’re growing in soil or a hydroponic system.
In most cases, a 6”-inch inline exhaust fan will be powerful enough for most 4×4 grow tents.
However, if you plan on running an HID light fixture that’s emitting a lot of heat then you might need to upgrade to an 8-inch fan.
Moreover, if you’re only growing a few plants under an efficient LED light fixture then you might be able to get away with using a 4-inch exhaust fan.
4×4 Grow Tent CFM
Most 4×4 grow tents require an exhaust fan that is capable of moving air at a rate of 200 to 400 cubic feet per minute (CFM)
4×4 Grow Tent Turnover Rate
An exhaust fan should turn over the air in a 4×4 grow tent 1 to 5 times a minute.
When buying an exhaust fan, you want to make sure it is suitable for the size of your grow tent. Choose an exhaust fan that can move at least 200 cubic feet per minute (CFM) airflow, depending on how many plants are inside the grow tent ( higher CFM ratings are better).
