Why thank you, thank you very much. Im gonna get some more pics tomorrow. These plants blew up overnight. We bumped up their nutes, started giving them bloom nutes, gave them a little beasti bloomz, and started them on 12/12. I dont know what did it, but i was amazed this morning. Ill get some pics tomorrow and you can see the product of that room :)

Nope, that duct you see coming in the room is just the duct on the left side of the light going out of the building, making a little U then coming in right beside itself.

Why do you do that with running the duct out an then back in again? Why don't you just take the hose off the left side of the reflector and let the fan suck the air in through your lower intake hole and then it will flow into the reflector, through the fan and then the charcoal filter?

Because then it wouldnt be sucking from a higher level. We tried that, and it being just those 3 feet higher did wonders. It slows it down a little bit. Trust me, everything in this room serves a purpose.

get a squirrel cage or inline fan. calculate the cubic feet of your box. you will want a fan that will change that amount in less than a minute with a 600 in there. C.F.=C.F.M. so u can change the air every minute. u will want alot of good ventilation in that box. if not your going to run into more problems than ya got now.

same predicament. do you still need to circulate it every minute if you vent your light separately? i heard somewhere that you only need to circulate it once every five minutes mathematically because the circulating fans move the CO2 around the plants sufficiently within the five minutes. yes or no?:joint::peace::blsmoke:

yeah 5 minutes is like the minimum. i would say u need to change the air more often for heat issues than co2 issues. but they always need fresh air.
