I'm planning a small lowland chamber as an experimental project, to be possibly done on a larger scale if it works out. I'm planning on basically constructing an aquarium, but out of mirror, so that I will get maximum reflectivity for the lights. Has anyone tried this? I've investigated glass cutting a little, and it doesn't seem too hard. I have a giant mirror that we pulled out of the bathroom when we remodeled, so that's free. I'm planning on attaching the edges with superglue, then sealing with aquarium silicone.
I'll probably do something in the front like others have done with the plastic track with sliding glass for doors. Other suggestions for the door are also appreciated. The top will be partly mirror and partly clear glass for the lights to shine through.
One other question: how tall should I make this chamber? I want to give the plants some room to grow so that I don't have to make a new chamber too soon, but don't want the lights to be too far away. The lighting will be 4 2-foot t8s. Right now the plants are in an aquarium that is 30" x 12" x 18", with only 2 bulbs, and the plants seem happy, with temps over 80 during the day, 70 at night, and 90% humidity.
Thanks in advance!
