Question about vent fans...

Have a 6 inch vent on the top of my grow tent and a 4 inch one near the bottom. Will I suffocate my plants if I have a 6 in fan drawing air out and a 4 in one drawing it in? Or will it equalize itself? Thanks.

WTF do you want an intake fan for?

I thought it would help keep the air fresh inside the tent. But I am just starting out (haven't even started the grow yet). So you are saying I should only have fans drawing air out (and that as many of them as possible is good or I should go with a set amount)? Thanks again.

Exhaust fans are all you'll ever need. Intake fans create bottlenecks. The amount of airflow you'll need is dependent on wattage, grow space, and layout. I suspect the 6" will be fine.

Yeah, it's a small tent with one stealth bubbleponics grow. I would imagine one 6 incher would get the job done. Thanks again for the info. Mods can close this thread if need be.

you need fresh air comming in. either from outside or via co2 tank.
