Today I bought 4 Rex begonias that I want to move out to my deck when the weather gets warm. The tag says "Medium Light". Most of my house is pretty dark as far as sunlight goes, but I do have flourescent lights in my basement that I use to grow seeds. Can I put the begonias under these lights for a few hours/day until spring? Will this be too much light (or maybe not enough)? I would actually like to keep them as house plant until spring if possible...do you think the shady conditions in my house would cause them to not thrive? Thanks for any advice.
