My 1st Grow Room!! Too Hot!!

[Juls7892]

7x2x5 closet, 600w HPS light, I have 4 ventilation fans ($12 bathroom fans 50cfm) I have one large box fan that stays on high, and one of the bathroom fans is actually placed in an open window, with ducting tube blowing the cool air directly at the light, as well as one fan the ducting tube directing the air out into the bedroom. The temp is staying at around 91F. I cant afford much more but I can stop now I have done a lot of work and already spent a lot of money on this, but I want to do it properly! It seems that a lot of air is circulating throughout the room but the temp just worries me. In the pics the thermometer is placed under the light and I have since placed it inside a little cardboard box to shade if from the direct light, it dropped about 5 degrees which brought it down to 91F. Please help any suggestions are appreciated!

hi guy, i can see you have spent some time and cash trying to get
yourself set-up.

what you need to do is,either get a blower for exhaust or use the
fans you have to exhaust the hot air out.
while you definately need air circulation inside your grow room, that
won't help to regulate temps.

here are a few links that might help, a few for DIY and one for buying

The closet has a total of 70 cubic feet of air, you should be all right with 2 or 3 of these 50cfm fan blowing the air outside the close, but still, it depends on where it's blowing the air, if all the hot air is stock in the room it may not really help you out. Getting the air outside the room / house might be the only solution to get the temps down.
