Jan: That's a great use for those plastic kitty litter containers. I have a cat but don't know why I never thought of using the plastic bins when they are empty! I have a 5 gal bucket that sea salt came in for my husbands aquarium and I use it for filling with water and fertilizer when I'm feeding my orchids. The big plastic kitty litter containers would be perfect for storage or holding water/fertilizer too.
