Gardennut I have seen people grow all the veggies they would want in kiddie pools in apartments on their roof tops. They don't take much soil and I have one that I poked holes in the bottom of and planted it with strawberries. And the berry plants love it and are going crazy.
I think I saw your pics of bags and kiddie pool gardening. Do you use potting soil or garden soil? I assume you drill holes in the bottom of the pool for drainage. My driveway is the sunniest area I have, and I have quite a few pots. But now I may try your kiddie pool suggestion. I enjoy trying different projects like this. I still need to transform a pallet into a planter for my daughter too.
