Man, I'm really sorry to hear the heat's affecting you guys so bad. Maybe build your own cooltube, I've seen some people on this site do it for pretty cheap, and you might be able to try for even cheaper.

I'll keep thinking about this. It would be sad to see such a waste after so much hard work.
graph Reviewed by graph on . Ballast question Hi all I got a 400W MH lamp with a ballast. Also have a 600W HPS for flowering, also with a ballast. Problem is, I'm vegging with the 400W but the weather is just too hot. I can manage temps with difficulty. If the weather doesnt change soon, I will have major problems with flowering once I switch to 600HPS. What I want to do is to get a 400W HPS bulb for flowering, I'll use the 600W exclusively in winter. Question is, can a 400W HPS bulb be safely connected to the ballast of a 400W Rating: 5
