I use LEDs for my veggies. But I am using 4' T-5 Fluorescents for the Bananas. If you look at my picture gallery you will see they are progressing just fine. I have the lighting hung on the wall vertically every 2' on slides that I can raise as the plants get taller. They are putting out leaves appr. every 2 weeks. I give them 1/2 gallon of water every week. The room is kept at 70*f @ 60% RH. Even the citrus and coffee trees are doing well under this lighting and they are mostly covered by the banana leaves.
