The Forest Roots worm farm is an easy and efficient way to convert organic household waste into liquid fertilizer (the worm wee) and a very rich, nutrient dense organic compost (the worm castings), known as vermicompost. The farm is made up of two tiers. The top tier of this 2 layered system is where you will start the worm farm. The worm wee will filter through the holes and the liquid gold will accumulate at the bottom level where there is a tap to bottle all that goodness as needed. The best part of the Forest Roots worm farm is that you are able to purchase additional levels as your worm farm expands, allowing you to build it up in your own time.
