Red Mountain Makers shows you how to make charcoal for biochar using a 55 gal drum and 30 gal drum retort as originally designed by Living Web Farms.
Makes 10 gallons of crushed biochar for composting. This video walks you through making the charcoal part, DO NOT put this straight into your garden, you must compost it first for at least 30 - 45 days.
