I am in my third year of planting heirloom tomatoes, peppers, cucumbers, eggplants, and squash in 10-gallon grow bags which are set in medium-size kiddie pools (3 to a pool). I live in inland southern California, so this is a perfect system. I don't have to spend all my time watering. I put about an inch or two of water in the tubs and then let the bags wick it up. About every third day, I let the pools dry out. This is the first year I have done this, and I think the plants look better and it's good for getting rid of mosquitos. I always get lots of vegetables. All plants go in tomato cages and I clip them together at the top with clothespins for stability.
