Wow...thats a great idea...good job (on the write up as well, very detailed)...but if you had a problem finding a glass tube big enough, then damn, I got a huge Gavita enhanced spectrum 400w bulb...probably about the size of your glass cool tube and the shape of a MH bulb.

Would this work for the single source of exhaust in a smaller room? (along with an intake of course)
indicloset Reviewed by indicloset on . Homemade 1000w cool tube! First off let me say! that I asked around this forum several months ago about cool tubes for lights,we all know how exspensive those cool tube's with fans can be!...............by the time you buy the hood with glass $200 then you have to buy the fan and the duct work another $160 or so,it can get exspensive and odds are you will have to order most of it through the mail,which has a shipping and handling rate of another $50 to $80 bucks depending on where you live!......... So believe it or Rating: 5
