That is all gone now though.....The duckweed pond became a seed germination bed and the stack of pipes were removed for vertical towers that I am messing with. The seedling germination is working so well that I am considering taking the cress bed and turning that into a seed bed too. I have a sump under one of the grow beds that is getting enough light for cress on a raft over its surface.
