I have a small pond so I decided to use a 100 gal stock tank for a grow bed, I have these nice collard greens growing that I feed from draining my fish tanks when I do water changes. I transplanted a couple of the collard green plants into the stock tank, was just curious to see who they'd do. Looks like they are doing fine so far. I plan on planting a dwarf lemon tree this spring and let it shade the pond and plant various veggies around the tree. What do you think?
