basement growers running muptiple lights, how do you keep it cool?

[glann]

I know basements usually are cooler, but say you're running 4 600's, how would you go about keeping it in the 70's in there?

a little more info would help.... open hoods ? cooltubes ? vertical setup ? do you have access to a window ? size of the room ? got a pic of the room ?

I run multi lights all in dif tents but in one "lung" room. I couldnt do it without my portable ac. I just vent it out of my room into the rest of my basement. I run air cooled hoods but I do not vent them out of the lung room.

a sealed loop intake and exhaust for the lights, a dehumidifier and a mini split ac. perfect control.

This is a hypothetical. I know even in winter my lights get hot in a non insinuated building

Environmental controler. In the winter time i run intake/ exhaust and in the summer i run a 15000btu window ac. My room stays 81° lights on and 66° lights off. Co2 runs whenever exhaust or ac is off.vI run 6x600w aircooled lights in a closed loop. Works great for me. Just have to swap out ac and exhaust once a year.

I have a sealed room in the basement. Flower room is 4 600w air cooled. Dehumid and ac are what you need. My temps range from 74-79. Never changes from that. In the winter I shut off the exhaust fans for the lights and just run the ac. works great

figure out a way to get forced fresh air (outside air) into your grow room during lights on. was the only way I could get temps down in my room without spending a fortune on a/c equipment. added bonus - outside air is 1200 ppm co2.

I know global warming is bad but we're not exactly at 1200ppm of c02 in the atmosphere just yet. Outside air will give you 400ppm at most.

right now im running 3-1000's on a closed loop with one of these http://www.htgsupply.com/Product-GrowBright-Mach-%208-Exhaust-Fan.asp, im not running co2 or dehumidifers or ac right now and my room stays perty much between 78-80 Degrees

Screw the AC hoods and fans and ducting and all the bullshit with dirty glass and condensate on the ducting and neighbors asking what that whooshing sound is and just get a mini split.
4,000 BTU for every 1k of light
