Making an Indoor Greenhouse
One month ago, I built a bottom heated seed bed with overhead grow lights that I keep in my cellar. Here's an address with the instructions how to do it.
It was a helpful guide for me. I used ordinary shop lights, and put in one cool white, and one warm white tube to give a wide spectrum of light. I put plastic curtains around it. Shower curtains will work, and I laid a thin sheet of insulation board over the top of the frame. This is a picture I took when the project was nearly completed. I have a large variety of seedlings growing in it now. They are vigorous with a nice shade of green. I'm very pleased with the results. Good luck. (03/29/2010)
