Hi- Regarding the light bulb wattage: I went back downstairs to the basement, got up on a chair and took a closer look at the fluoro tubes. They said 40CW; I had read that C as a 0, and not being familiar with fluoro lights I didn't question it. Guess if I had tri-focals I would have read it correctly! Thanks for the help, everyone. Bill, stay tuned for more questions, especially when seeds get started. Diane
