Since my tomatoes were in containers, I was able to bring them inside a few times this winter as the temps plunged into the lower 40s, so I've been able to get a constant production for months. The second time I brought them in, instead of just "balancing" them on the ledge between the living room and kitchen, I grabbed a couple pieces of an old dock gate out of the back of the truck and with a floor flange and a piece of 3/4" pipe I built a stand which worked out great.
But then at Lowes I found these planters designed to sit on a fence (or perhaps a ledge between two rooms). I've got plenty of sunny space on the dock, several feet from the existing hydroponics, so I ran another line and planted some tomatoes. I think this is going to work out well, especially in the winter.
The tomato on the right in the second picture is actually a decent size chunk I found on my living room floor one cold winter morning, BTW.
