At first I was wondering why you would by 6 rolls of aluminum tape when a big roll of mylar would be better and cheaper. I was wondering why you would need 2 tubs and why you were only using 6 CFL's. After looking at the setup I understand. It's a very sweet looking setup; I only wish he had followed up with a grow journal to see if it really worked out for him. 150 watts isn't much light and from what I read in the thread it got into the 90's in the box - not bad in the winter but during the summer that's going to be a problem unless you have it in an AC'd room.
