Produced in Berkeley California from locally sourced walnut shells, this high-temperature biochar is low tar and electrically conductive, to enhance the electron exchange of the microorganisms in your compost pile and allow you to achieve better temperatures and a faster composting process. 

Once in the soil, the increased cation exchange capacity, will result in a higher plant growth rate.

The Biochar also stimulates the production of humic acid so you will have more compost (and less emissions) starting from the same amount of veggie material. 

Addition of biochar to the compost pile has a significant climate impact. Your yearly subscription has a positive climate impact of up to 1 ton CO2e – that is equivalent to 1.3 acres of US forests storing carbon for a year.

This insulated steel tumbler allows you to maintain high composting temperatures with relatively small amounts of organic material. It is also resistant to outdoor weather, is easy to tumble and resistant to pests.

The subscription allows you to pay off your tumbler over a full year.
