Hello again, just gotta say I love this site. Gotta question. I'm thinking about moving all of my Phals to the basement. Right now I have them in a shaded west window with a two tube fluorescent fixture. How many more fixtures do I need for good growth and flowering. There would be little to no natural light, I would rather have a sunroom but, I gotta work with what I have. So any advice would be great! Thanks
