my daughter has started an Oliver Wendall-Douglas farm, (lol), tomatoes being some of the crop. she grows them in pots & uses reclaimed h2o for watering -so far so good, but the Florida heat & sun have presented a challenge. the plants need light watering through the day to keep leaves from getting crispy, but not too much or it will produce poor results in fruit. i think it's more or less a hobby now, hit or miss to see what will grow or not.
