I installed my tomato trellis with 2 1/2" screws and jute twine. I left space behind for air flow.for the trellis I used concrete reinforcement wire. Yes it's an overkill. I had a role on hand so why not. Some of the leaves were looking a little cooked on the jalapeños, Habeneros, and Seranos. I pruned their lower leaves and dimmed the light to 30%.
