Thanks for the reply and for the idea on going with the 400 watt in case I upgrade later. Very good point.

On the fan, I was actually thinking of a "glass lensed reflector" with a 4" flange, instead of the typical cool tube. Mostly because of space constraints. I do have a 6" Home Depot fan that I will be upgrading to the 6" Elicent Centrifugal Inline Duct Fan. So thats even better since I won't have wasted my money on that otherwise crappy fan. Do you think the HD fan will be enough to keep an HPS or MH conversion bulb cool enough to not add to the ambient temp?

I am really worried about heat due to my experience with that 6" fan in my veg area. I am using CFL's only (65w x 2 and 26w x4) and the temps are getting in the mid 80's to 90's. I have 2 x 4" passive intakes as well, and haven't even put on a carbon filter. I really hope the Elicent fan fixes that problem...
