Compost Sure (Green) is a mixture of hemp core (stalk) and course sphagnum peat moss. Compost Sure comes in an 8 gallon (30 Litre) bag. It consists of coarse peat moss and chopped hemp stalk. Hemp will decompose where wood shavings and peat moss do not – giving your compost a longer residency time! More importantly, it saves you the time of making your own mix.It holds moisture to help maintain the moisture content in the compost. It also ensures good porosity so that liquid can drain easily, leaving behind free air space for oxygen. Finally, Compost Sure (Green) offers a biologically active matrix.
