I make my own Bio char.
I was hoping to get a better yield out of my Potting mix using some of my own ingredients.
Hoping for better nutrient and water retention for my indoor grow.
Also figured that coffee grounds would add some ferts, at least nitrogen.
Hoping to do away with black cow and using compost from our recycle center, and hoping the coarse biochar reduces the need for lime and perlite.

After the indoor grow, potting mix will be used in the pond for my aquaponic peppers, then at the end of the season they'll be dumped in the hugelkultur beds. Figured I could add a bit more biochar to help filter the pond.
Well that's the plan anyway
