Hello there @samstonehill
This is some very interesting info. But I was wondering what would happen if you placed rods at the corner of each bed in line with the cardinal directions. Copper wire in the soil with magnets, copper wire up each rod then over to a central rod where all the wires meet. Has anyone tried that ? Only reason I've thought about this is, I read a book by Robert Monroe who speaks of the copper pyramid accelerating someones ability to dream awake.
