Over the past few years, everything that wasn't in a greenhouse, or in front of a window, was in the cellar. Because of the boiler being there, it's warm. (normal room temperatures) Watering was regular house plant type watering, maybe once a week, or so, more if the soil seems real dry. (there are other plants beside bananas there) Lighting is just plain old fluorescent shop lights, and everything does fine.
I once had an aquarium fish import business. We had some of those Gro-lux tubes, that gave off a pinkish or purplish light. They were expensive, and made red fish appear very bright, but I really couldn't notice any difference in plant growth.
