ventilation help

hi all,

im new to the site and growing but am excited. ive been researching for weeks but have been unable to find an answer to this question. if i have an exhaust and carbon filter which would cause neg pressure in my tent and using a passive intake method, would i still need an oscilating fans inside the tent to move air around or will the exhaust take care of that? any help would be appriciated. thanks.

YES, You still need a oscilating fan to have air circulation in the tent..

yes a small fan is a must for proper air circulation

yessir. i use a couple 20"box fans work like a charm! id also try putting it in front of your passive intake bro

i was thinking of getting 2 small 6" fans that i can clip onto the poles but that sounds like a good idea. maybe i'll go with one small 6" and a small box fan also. thanks for all the help.

I've got 7 fans in my small 4x4 tent. They're all small fans @ 6" or smaller. I have one 190cfm for exhaust, two 4" axial fans for intake, a 4" duct fan for intake, 6" oscillating fan blowing between top of canopy and hood, and two 4" fans on the floor blowing cool air upwards.

and you want a fan inside as well to blow on ur plants to help strengthen the main stalk.
