Ventilation Question

[curious101]

Well i grow in a 3 wall room with a curtain and use fans continuously during the light cycle...i then turn them off with the lights because i've given the curtain about 8 inches of open space on both the top and bottom....temp drops between 7-8 deg F...is that alright or should i leave one of my fans on during the night for a little extra air movement...thanks

if you r talking bout an exhaust fan mine goes off when the lights do but i always keep a circulating fan on. outside air movement never stops, so just think about trying to replicate a perfect outside environment. good luck

All ventilation/circulaltion fans should be on 24/7, unless you are running co2. When temps drop, relative humidity rises. If you have a decent sized grow (ie running a couple thousands watts HID w/ two dozen plants or so) then temps drop enough to form dew. You don't want dew to form so you got to keep that air circulating.

Even a small grow benefits from constant fresh air and a stem-strengthening breeze.
