Hi Claudia Mike et al

I put my coffee grounds in the worm farm with the biochar (with food scraps) and then the worms do my work for me as they injest both.  I keep my worm farm outside and when it rains I get this wonderful dark brown to black  liquid full of  very small particles of biochar that are full of a whole range of nutrients.  I will do some scanning electron microscopy of the  particles tonight.    Here is a batch just come out from the worm farm after a small rain event.

…I guess there are tons and tons of coffee remains every day with Starbucks and co. Might be nice to soak the remains and biochar together and let it dry up – accelerated “ageing” and the used coffee powder makes nice soil additives anyway.


cheers, Claudia

As needed, we will soak our wood biochar in a humic acid/kelp extract.  


The coffee idea is a wake up call for biochar.....
