The Mini hut is doing great, thanks for asking. I just got everything switched over on Sunday and reppotted my seedlings yesterday. The temperatures in the hut with the 400w cooltube are a marvelous 1 degree above the outside room temps so the fans are doing their job just fine! There is more radiant heat from the bulb than I expected but if I keep it 15" - 20" away, it should be fine. At this time, I'm more like 36" away because they are just seedlings and actually they are struggling seedlings at that. I think I had them in too "hot" a soil for seedlings and a few appear near death. I transplanted them into some Fox Farms Lite Warrior yesterday so hopefully they will live despite my best attempts at murdering them.

I'll post a pic or 2 of the hut tonight when I get home...
