im thinking of the 100w one on a 2x2 tent, what about intake/exhaust fans, are they necessary for that 100w qb that barely produces any heat?i need as silent as possible.
Use 1 or 2 small clipon fans inside. Monitor the inside temp. Know that once the plant is in flower and full canopy the temp n humidity will go up.
Intake, tent should have a hole/inlet at the bottom and one for outlet at the top. Inlet can be left open to pull in fresh air/CO2. Outlet, if smell not an issue, a small fan to pull heat out thru the top. KEEP IN MIND LIGHT LEAKS!!!
Hope this helps.
