Carbon Gold Promo Codes & Coupons September 2026 — Up to 20% Off

Carbon Gold was founded by Craig sam, founder of the Green & black Chocolate company. After years of third-party scientific trials with incredible results on the effects of their rich biochar on plant health, their natural organic biochar product was quickly adopted by the commercial crop growing, tree care and sports turf sectors. Carbon Gold's products are unique and no other horticultural product can be compared! Its biochar products are 100% free of peat and synthetic chemicals and are approved by the Soil Association for organic farming, although they are often used by traditional and organic growers. In addition to being approved by the Soil Association, the sustainability of their products is also guaranteed by the FSC® (Forest Stewardship Council) and RHP approved for use in Dutch cropping systems and Demeter approved for use in biodynamic systems.
