On the subject of the metal stock tank that Debbie said she was using, are they all galvanized? Surely if they are safe for animals to drink water out of, they should be safe to grow veggies in?
I'm also pretty sure that "back in the day" a couple of my Dad's sailboats had galvanized water tanks for people to drink out of. If zinc is the issue, I think it's in some vitamins as a trace mineral, and I know it's in supplements for "eye health" like Ocuvite.
I really like reading Rick's posts when he gets going on soil science, and anti-gravity . . . Hmm, anti-gravity would be great for a lot of things besides gardening. Like keeping my face and other body parts from ahh, sagging?
