I have some buckets tah we're going to turn into tomato growers. I wonder if regular sized tomatoes can be grown like that too? Anyway I'm going to plant marigolds on the top of the pots.
Here is a link with a picture and a description of what I got. The frame is supported by pvc pipe, so I don't have to rig any kind of system. Supposedly, all I have to do is fill the bottom part with sand, the top part with upside down tomatoes and dirt and whatever herbs I want with the tomatoes, and sit back to wait for my 'maters (LOL!).
