How long does each Worm Factory® tray take to finish?

After you begin composting with your Worm Factory®, the first tray of compost will take 2-4 months to finish. It could be faster or slower depending on how many worms you start with, how often you feed them, and how quickly the other beneficial microbes in the compost become established and multiply. As you add trays, they will all be at different stages of composting, and you will be able to harvest about a tray a month.
