Do you really have enough room to bring them inside in the winter? That was always the issue I had. I ended up devoting a room to a desk, and two large Ikea wooden shelving structures with grow lights. All my neighbors thought I was growing ganja, but it wasn't me, it was my neighbor downstairs that did that. I could smell it right before he harvested it (long story but he rigged a room off his closet that came up through the wall between my two closets and hung some really large lights (halide in nature), always wondered why my appartment was so warm (and then cold once he moved out)). Building owner asked what he was doing and I played dumb (and laughed hysterically later that evening).
