JMG recently mentioned using an Earth pipe, invented by Galen T. Hieronymus, to increase garden production. I've done some searching and found it called a cosmic pipe or a field broadcaster--found lots of background information, too, and a few places selling field broadcasting services for commercial farmers--but have yet to turn up any DIY instructions. Has anyone ever tried one of these before, especially for small-scale home garden? Do you have instructions for building and installing?
