How To Make A Flow Through Worm Composter

Make a flow-through worm composting bin using a 13-gallon kitchen trashcan, some scrap wood and string trimmer wire. A flow-through worm composter makes harvesting worm castings easier than hand-sorting by creating a bin with an open bottom. A grid of trimmer string supports the soil column while allowing it to slowly flow through into a catch container. The red wiggler composting worms migrate up while the finished moves down through a compression zone, naturally separating the worms from the castings.

For my worm composters I use worms purchased from Uncle Jim's Worm Farm. Uncle Jim will give you a 10% discount on your online purchase if you use the coupon code "greenshortz" at checkout. website: www.unclejimswormfarm.com
