Compost with a kick!

Activated Compost is an OMRI Listed, plant-based compost which has gone through a Secondary Activation Phase. In this stage organically approved ingredients are added at a specific time, resulting in a unique bio-catalytic effect, where microbial life flourishes. Nutrients are metabolized by microbes in the compost and are more readily available to your plants. Purple Cow Activated Compost makes nutrients more available for plant uptake, and is an ideal amendment to improve soil and growing media.
