OK, you lost me. What cooling are you referring to? The units on the page you sent me to look almost identical to what I was looking at. I know I am missing something, but I am unsure to what it is.

Also, I am going to need a HPS and a MH bulb right? MH for my vegging and HPS for flowering.

How about this unit?

It also comes from Pittsburgh :thumbsup: Go city of champions...
