Too much negative pressure?

Your exhaust far exceeds your intake, and its trying to find places to suck air from.

Just take a length of flexible aluminum tubing. Make an "S" shape or a loop, so light can't come in or out. Start with a 4". You may need to add more, if the diameter is not big enough. Seal the end coming into your tent with (duct) tape. Some filter material in the intake end will keep out dust, etc.

Couldnt i just not zip the tent up all the way leaving larger intake vents? This is what ive done and my tent walls are still being sucked in but not nearly as much. I figured as long as those walls are being pulled in then basically no smell is escaping. But now you have me worried about sucking shit into my tent that doesnt need to be there.

Finishing up a tent grow and used positive pressure for the first time and I think I will continue doing it.

My intake is much stronger than outgoing, tent balloons, there are light leaks and smell leaks, but I keep it in a dark room at lights off and smell doesn't matter for me.

That being said, my plants look very happy, even though they are pretty close to the lights. There is no stale air, it is circulating around until it gets exhausted. No harsh winds from oscillating fans but steady, consistent air movement.

My next grow room might just be a big climate controlled room with a bunch of tents in it, each with their own positive vibration.bongsmilie
