I’ve been using my Farm Plus gardens for a while now, and have noticed that plants on the left side of each garden seem to grow better than on the right side. I already had a digital level, and I measured that the left side of the garden slopes down by an angle of about one degree. I live in a concrete high rise, and the poured concrete floors aren’t perfectly level. Water flows through the hollow deck of the gardens to trickle down into the pods, and I suspect that the pods on the right side are being deprived of water because of this slope. The slope isn’t enough to be visible to the naked eye. I’ll buy some shims at Home Depot to try to level the garden to see if that helps. I sent a question to AG to ask their advice.
