Got about 3 cups of char from my woodstove lat night. It's not much, but it adds up. It's also a bonus for an activity that I am already doing. #biochar #homestead #permaculture #hacks #zap #grownostr

Cool! Whatβs your secret for making biochar in your woodstove?
I have both a chimney flue and and air intake cut off. When I know I am going to bed and don't need to keep adding wood, I close both off. Depending on the coal bed, determines how well the remaining wood chars.
Ever thought of doing this? https://youtu.be/k2sqdvboKl8
I will check this out after work. Thanks
