Jake, Oh those tomato caterpillar are major PITAS! At least they are easy to kill. A trick I do to prep soil where I might plant in the ground is after I chop I take the soil from the pots and dump them in the area and then let nature do its thing over the winter and come spring any nutes left over in the soil has washed into the ground. I just harvested some of my AF's and have another load on the clothes line.
