If both of those lights are non air cooled then ur gonna need exhaust and intake fans. I have one 600w cooltube in a 3x3x7 and my 250cfm inline fan isn't enough! Get a big exhaust fan like 500cfm and an intake fan probably a lil smaller so u have a little negative pressure

Im growing in a 3' x 3' by 7' closet with a 600w hps and we have HEAT issues you're gonna need a powerful fan 350-500cfm if you wanna run a HID light

Thanks for all the replies!! :-) @darkdestruction i hope that doesn't happen to my light jeeze.. I went to the hydro store with my ballast, they plugged it in to a light and it worked! So I went home brought back my bulb instead; they plugged it in and nothing happened. Just a dud bulb. And...

What nutes do you have? and it sounds like ur starting from seed For the first week or two from seed dont add nutes. after that use a light dose 200-400ppm (parts per million). As the plant gets bigger you add a solution with higher ppm's but the max u wanna give them is gonna be about 1500...

Ding ding winner I was gonna say the same thing. If you bought a quatro it looks 2gs short yo

250w cooltube might work. i think a 400 would make that lil cab too hot

Water it! Your soil should be moist..

im going to buy a DR80 or DR120. Would a 1000W light work or is it too big for those tents? Plannin on 6" cooltube setup

I've been following bongmans threads cuz i got a closet the same size that i needed to find a way to vent and we went with a 4" exhaust and 4"passive intake and it seems to have slight negative pressure i read you should have a bigger exhaust to create enough negative pressure so u won't have...

How bigs the room? U need some ducting fans and a cooltube. Or an a/c.
