Worm composting is an incredibly efficient way to convert kitchen waste, garbage, and cardboard into nutrient-rich compost for your garden. Compost produced by worms achieves the best results and helps your plants thrive. Just add worms and your organic waste into the bottom tub and the worms begin to process the food. Once the tray is filled, add another tray so that the worms migrate upwards to the newest food source. The bottom tray is full of nutrient-rich compost. The moisture protection filter filters waste through the system and attract nutrient-rich particles. You can drain the organic liquid fertilizer from the tap.
