Thanks for the kind words and advise HARDON.

I asked Zandor if it would be beneficial to run both bulbs and he said that mixing lights was a good thing. I still plan on buying a pair of 42W 6500K bulbs to help with side lighting during veg.

So you wouldn't run both during veg? What about while flowering? My budget wont allow another 125W bulb + socket at the moment.

If you say the 2700K bulb won't do any good until flower, how do some people only use HPS from start to finish? No offense, just wondering.

The heat off the AC unit is very tolerable at 1/3 power, which is what I'm running. I can double check temps later when I get back. I crack the closet open a few inches with a fan blowing air out and then a 20" box fan installed in the window is furiously sucking air out of the entire room.

The passive exhaust will be located on the top section of the cabinet. It will be sandwiched like this...

grate
furnace filter
activated carbon
furnace filter
^ air flow

You can see the uninstalled filters just chillin on top of the white grate in one of the pics. Damn, I wrote a lot... must be because I haven't smoked Her Majesty.
