Cool, I'm interested in doing this, also If you can document any difference between the over driven
lights and the lights that are not over driven would be great information. During the summer I may be able to find a place to setup a small place for lettuce in the house, where I would be able to better control the air and
nutrient temps.
P.S. Also the difference in energy consumption. In order to decide weather it's more reasonable to just double the lights rather than the ballasts.
