Growing tomatoes in containers : Each bucket has two 6' pipes zip-tied to the inside with 3 zip ties on each side, then two elbows at the top and a 10" piece between them. The goal is to do a Florida weave between the two pipes in each bucket as its resident grows.
One tip is to get the zip ties closed loosely in place, then slide the pipe down into the loops, then tighten.
