Right o.

Okay, attached are my images, and here's what I've got.

- Totally mylar sheets up everywhere.
- 45W floros (2x), one with tin foil as a reflector on the ground, the other hanging with a reflector dish.
- 100W HPS (1x), hanging in the middle.
- 20W 24" floros (6x), mounted on one of the walls. I figure they'll be in good position as the plants grow a bit.
- 1000W HPS (1x), on order, should be here with more than enough time for the plants to really need it.
- Skylight (1x). Provides a pretty hefty glow of light into the room. Not sure exactly how good that is, but it's free, comes from the sun, makes the room brighter, and doesn't add heat (well, not much anyway since all light has a bit of heat).

In regards to sealing it up during the 12/12 cycle, that would be hard to do at all. It's easy to reach with a ladder, and I'll just tape a trash bag or other opaque object over it when need be.

I'm getting the 1000W HPS system because I don't want to screw around here. I figure if I'm going to go through all the trouble of setting this stuff up, I might as well do it right and have a bunch of plants with a high yield. As good as I can do, anyway.

As far as ventilation, I'm really pretty set I think. There's a nearly constant flow of air through this room, naturally exiting the little window (pictured), which is now greatly sped up by that fan blowing exhaust out. I have another fan which is blowing the pots, and lights. Right now, granted the 1000W HPS isn't in there, the room is quite cool.
