How and when to harvest the compost/castings?

After 2-3 months or when your Subpod is full, you can harvest your Subpod compost. To do this, feed only one compost bay until all the worms migrate to that side. You can then scoop out your finished compost from the other bay after two weeks, and begin the process again. Unlike other compost systems, you don’t need a resting period to collect your compost. By alternating bays, you can keep feeding your system as you collect your compost.
