Thanks for the reply, I'm wondering if there's a way to filter all of that out. I'm really really curious on how to make carts so I'll be doing mad research on this. Also I'm wondering if there's any toxic metals in the carts themselves. This is a bit more complicated then I thought, and I'm assuming I'll need some extra equipment to separate all of that out...how about instead of father figure we an just call you the Dab Daddy
