Thanks to our subscriber packages we are able to provide free biochar to local community gardens and double your climate impact. Currently our product is available for pick up only at our Berkeley hub in California. (Please contact us if you would like to become a pick up spot for us in a different region).

The subscriber packages cover your yearly biochar needs and come with or without the Joraform tumbler.

SkyCarbon Biochar

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.
