Hello, I have a dark house. I decided to try some house plants that I couldn't pass up. Right now the plants are enjoying the summer outside, but I am wondering how to light them when I move them indoors. If I kept a few in each room, what would be a good option? If I opted for keeping them all in one room, is a T5HO fixture really needed or would a standard fluorescent fixture work? I have been reading a lot, and the T5HO seem to be a favorite suggestion, but I worry about the amount of heat it would generate. Thanks for any help.
