  • Ready to use - add to soil and containers for luscious plants and tasty vegetables

  • Lowest biochar prices, free delivery
  • Made in the UK using our propriety composting process

  • Great for the environment - locks carbon into your soil to reduce the impact of climate change.  

Biochar Super Compost (SF60) is the best soil improver, but please note it is not a "growing media" (ie a potting compost)

  • Please do not use it on its own to grow plants in - add it to compost and/or soil (10%, 1 part to 10 parts compost/soil)).   
  • Please note:
    • It does not look or feel like traditional compost - it will arrive damp and sticky
    • It is a mix of biochar, colloidal humus, and compost
    • It is black in colour

We have lots of blogs/articles describing what it is and how it works. If in doubt, we would much rather you contact us or read further before purchase. 

In our Biochar Super Compost (SF60) tests, we have seen an increase in plant and crop growth of 100% over the control soil. All plant growth testing is complex and it takes many test replications over a number of years before we will know the 'average' increase.  We believe most users can conservatively achieve a +20% increase in luscious plants and tasty vegetables.
