I was running a 400 in an area about that size in my basement for quite a while. Over the summer temps got a bit high, peeking into the 90's even with an 8 inch exhaust tube and inline fan (ghetto rig household booster fan in a cardboard tube with the inside painted black to block light)

I got the glass for the hood (Sunsystems-2 all in one deal) and pulled the heat from the bulb into the exhaust, dropped the temps into the mid to upper 70's!

The 250 wont properly light that whole area, but it should do nicely over 1-2 smaller plants. specially with the t-5's as side lighting.

High All, I have a closet its about 2-3' deep, 5' wide, 8' tall! for reasons that I wont get into I cant cut holes in ceilings or walls or etcetera! my question is, is there a way to grow some really good product in this givin space? I've vegged with great success in this closet under t-5's! but don't think the t-5's will bud successfully and have no way of venting hid, hps lighting. I have about $300 and am thinking I would like to use this space to flower also, but heat is going to be an Rating: 5
