Well , i had a rubbermaid grow box going , with 4 24W CFL's , and im aware that this is enough light to keep 1-2 plants happy. But with 4 bulbs the temps inside the box soar to a scorching 90F. By removing 2 bulbs i managed to down the temp to 80 - 82, my concern is , will i still be able to keep 2 plants happy with 2 24W Bulbs inside a rubbermaid style box. I have 1 big CPU exhaust fan pulling air out , and 2 internal CPU fans blowing air inside. And the temps are still a problem!! Any suggestions on cooling things down ? And will my plants be happy with 2 bulbs ? :confused:

ok you have exhaust and circulation fans, um what about intake?? How are you bringing cooler air into your growbox?? and loose the 2 fans inside the box they are only blowing hot air all over the place, keep your exhaust, create a passive intake that is twice the size of the exhaust and you should be fine, I have a 2 sq ft grow box, it has 3 42w and 5 26w, my temp peaks at 80-85
