Hubby wants to try something new this year. He wants to find a source for 5 gallon buckets and put tomatoe plants in them and sell them to people who have like an apartment situation, but have just enough room outside to set something like this to grow. His question is, how much could you charge for these and come out okay. We have very rich soil here and raise rabbits, so we could make up our own little fertilizer rich soil for the plants. What do you think? Also, any suggestions of other little plants that people might like to grow this way.
