Does anyone have experience with vertically growing pepper plants? I used to work on a farm that grew bell peppers vertically with Hydrostackers, but, it wasn't as impressive as I thought it could be. I get the impression that vertical grows aren't necessarily the best option for pepper plants as they're just too tall and bulky. Has anyone else had experience with it? Would you prefer growing it in soil close together (i.e. 2 plants per pot) over vertical growing?
