Picture 6: Top view of the box. You'll notice that two of the flaps are at an angle. I did this for 2 reasons. To strengthen the maximum weight support of the top, and secondly, to act as a sort of reflector.

Picture 7: This is a picture of the underside of the piece of plywood. I just about ran out of mylar here and pretty much pieced it together using scrap pieces. Do what you gotta do.

Picture 8: This is everything setup and lit up. No plants in there yet. Currently (not shown in the pic). I have my thermometer/humidity meter gauge in there for the next 30 minutes to an hour to see what the peak temperature is with the new setup before I put plants in there.

I'm anticipating at least DECENT results. There was alot of great airflow moving through the box.

All in all total time of making this box was about an hour or 2. Which 90% of that time comprised of me trying to hang mylar with my bad back.

What do you guys think? Any input?

Thanks

edit: Just wanted to note that My camera in the last picture had the shutter speed set as fast as it could go and the aperture almost completely down. Basically I told my camera to let in as little light as possible so the image would come out clear. The actual Light that comes out of that box is BLINDING!. 13000 Lumens Spread out over a 23"x23" area, a total of 8 1300 Lumen 6500k spectrum bulbs and 4 640 Lumen 6500k Specturm bulbs. They are 27watt (100 watt equiv) and 14watt (60watt equiv) respectively.. That's about 6500 Lumens per sq ft. Which is, from everything I've read, Pretty good?
