Worm Factory 360 Worm Composter

We absolutely love this worm composting bin! Sure, composting with worms in a standard box works just fine, but it also has major drawbacks. It’s a pain to sort out the worms, often too little oxygen gets into the mixture causing odor and other problems, and then there’s managing the runoff.

The Worm Factory 360 Worm Composter is a self-sorting worm composting bin. Here’s the difference between using a self-sorting method and using a standard box method for worm composting.

There are two main drawbacks to composting with worms using the standard box method (having just one container or box housing both the organic material and the worms). First, there’s the process of having to sort out the worms from the finished compost, second, there’s the issue of managing the excess moisture that drains from the bottom of the box, and third, there’s the issue of keeping air circulation in the mixture.

The Worm Factory 360 Worm Composter uses multiple trays, each modified with a grid bottom which can be stacked one on top of another. The grid bottom allows the worms to move from one tray to another. You begin by adding organic matter and worms to the first (bottom) tray. Once the first tray is filled with organic matter you can add a new tray on top. This process continues, adding additional empty trays once the lower tray is filled with material. As the worms process the contents of the lower tray, some of the worms migrate upward to the new food in the tray above. This removes the chore of separating the worms by hand. After a few months, the compost in the first tray at the bottom of the worm factory will be finished and ready for use with your garden or house plants. Excess moisture (which is rich in nutrients and microorganisms) drains down to the bottom of the worm factory into a resevoir at the bottom where you can drain it out with a spigot. Because the unit is raised off the ground, it’s very easy to get a container or watering can under the unit to collect the “worm tea.”

Finally, there’s the issue of keeping air circulating through the compost material. The worm factory bins have great air circulation. The rising heat and compost gases create a thermo siphon, drawing air up through the trays. The air enters the base on all four sides and is pulled upwards through the trays (through the channels created by the worms) and up through the lid. The manufacturer claims that this design allows for ten times more air circulation than similar composters. All in all, this is a fantastic worm composting system.
