Ok here's the plan. I have a closet 2'5x7 with a 30" door in the center that I have divided into three light tight compartments giving me 2 grow chambers 2',5"x 2'5" I have built a soffit across the back wall at the ceiling protruding into each chamber .I have mounted a fan into this soffit in the center space forcing air into each chamber out the bottom back to the center. I plain on using a duel hose portable a/c unit I'm thinking 9000 btu should be sufficient.This will be a sealed environment so I will be using a co2 tank with a solenoid valve on a timer , thinking that I can keep my levels stable if I have a tight enough seal.I'm thinking that I will need to put down 40 to 50 wats of led light per square foot of grow space. I plain on using 7 band lights one in each chamber 150 to 200 wats. Have not decided on which brand yet. Any comments/ suggestions would be greatly appreciated.
I'd exhaust from the top and intake from the bottom for better efficiency and I'd be shooting for an actual draw of 50+w/sqft but that's just my opinion.

I agree that it would be better to move the air in the opposite direction, but with the way the room is configured/space restricions and the type of fan I have (squirrel cage) it be way more diffacult to achieve. Im thinking with the a/c at floor level bringing the warm air down and blowing it across the floor to mix with the heavier refrigerated air will eliminate stratification. Keeping in mind that this is a sealed environment and not actually trying to remove the hot air only mix and cool. Any recommendations on A good light.Seems the led light industry is a treacherous landscape to navigate,full of shyster and swindlers.
