This is the Season Finale and in this episode, I'm interviewing the Char-Man of the Board of Blue Sky Biochar, Michael Wittman.

He shares SO much information in this interview on everything from his background, growing up in the Bronx, NY and his first experiences with Grandmother growing food, to explaining in depth what biochar is, how it works to regenerate soil and how to create living soil.

It's worth the full hour listen, but no matter whether you're a "backyard gardener" or a full on crop grower of hemp, you'll get a little bit of everything in this interview. And if you just want to hear about what you're in to, check out the timestamp list below. And make sure to connect with him on social media or head over to to learn more about his products.
