Ok so I picked up some foam board insulation cut several holes into it and the put in plant baskets for hydrophonics. I figured Id try growing some regular lettuce and cabbage by floating them in the middle of my pond. Hoping it will work two fold. Give me some roots to help with my pond and produce something I can eat. Every time I try planting things normally the deer eat the heck out of them. Im hoping they wont bother with it floating in the middle pf my 25x38 pond
