I ended up taking the eggplant and the bell pepper and putting them outside in the pond setup as neither would set fruit inside, guess maybe need to work on the pollinating skills. The bell already has at least a dozen peppers on it about an inch or so big. The eggplant puts out dozens of flowers but nothing sets and now is going downhill. Have added eggshell and epsom salts to no avail, just not destined to have eggplant. The ghost pepper is still inside and flowering like crazy but no peppers. How much distance is needed between species to help prevent cross pollination?
