HELP! Ventilation Exhaust Fan Concern

[allmyown]

I just put this exhaust fan carbine filter combo iPower 6 Inch 442 CFM Inline Fan, with 6 Inch Carbon Filter and 16 feet duct combo, 2 clamps included, grow tent ventilation system, in my 4x4x7 grow tent , i have it inside just like you see in photo . plugged it in and closed the tent up. OMGGGG my tent walls sucked in like 2", sealing the tent, and the exhaust is blowing out a strong steady flow of air. But im scared it might be to strong and hurting my plants .

Hey allmyown, I'd look in to a speed controller if you don't have one. It will allow to dial it down to the perfect setting and they're only like 15 bucks, I don't think it will hurt your plants.

[Mr.furley]

Iv got this one cheap and easy

The tent walls sucking in is good it means negative air pressure so no smells getting out

[allmyown]

More clear now , i read about negative pressure .

hey allmyown I did the same thing the first time I hooked mine up I sh-- myself turned it off installed more intake air and it still sucked in so I tried it out for a couple of days no damage to plants ,its been running ever since happy growing

Thanks oldjarhead100 for the insight . i actually bought a speed controller , and reduce the power . works great now , noise level reduce too.

[Mr.furley]

Those little speed control boxes are Priceless for environment control in a tent.
