Next week sometime I'm ordering a 125w compact floro. measures about 21" by 14.5" by 9". Comes like a HID lamp, only smaller.. HEHE.
The output in lumens is roughly 6800. I'm going to set up another area so I can move those plants out of there for maybe a couple weeks, I want the light to be closer than that.. it cant be right now, the ro0m is small, so the heat just stays right under the hood. (Its like foot 1/2 above them now!) After the plants get at least 12 to maybe 24" Ill move them back to HID, I think its to much for them.
The heat will be greatly reduced because the lamp will be higher. More air can flow UNDER the light, and the fan will do its job a lot better.
