Query: Not as good as I had hoped

I bought 2 to see how well it worked. I'm about halfway into the tomato season and the plants in the Topsy Turvy are about a 1/3 the size of the tomato plants that were planted in the ground. All the plants were from the same batch, planted the same day, and in the same location. It seems to dry out very quickly. Next year I'll try some different types of plants and see if I get better results.
