Knna, thanks that exactly what I want to do. What you have descriped right now I have 4 pc fans with 2 150 clfs and it 70 degs. I am going to get a dimer or speed control so I can slow them down to get it a little warmer in there. As for yield I would like to get about 8 oz out of two plants on a reg basis of two to 3 months. Its will be a learing experiance but seems alot of fun to grow in the chambers.
