How do varieties affect space and yield?
Greatly. For instance, if vertically caged, indeterminate tomato plants can reach 16′, so you have to think about the varieties you choose ahead of time. The Urban Farm produces such extraordinary results that you can become overwhelmed. For balconies and other limited spaces bush varieties help. The real answer is pruning and training, since our experience is that the best tasting tomatoes come from indeterminate (vineing type) varieties. Once you become brave enough to start nipping here and there you can grow even the large ones and control them.
