Coffee can worm farm

Coffee can worm farm: I use a coffee can to collect my grounds and teabags for  composting. I find the tight fitting lid prevents odors and spills. I know coffee grounds also will keep away snails so I wanted to keep them separate from my other vegetable matter. I change it two to three times before a new can replaces it and the old can goes out to surround my hostas and tender plants. I started turning them over so the liquids can seep out. Less nastiness as I spread the grounds around the plants! Next thing I know I have tons of earthworms I thought how perfect for someone that can't have a huge compost bin in their yard! It's easily hidden too!
