This process does two useful things for mushroom growers. First, the heat and pressure partially sanitise the raw wood material — reducing the ambient microbial load before sterilisation or pasteurisation even begins. Second, the compressed format means the sawdust particles are intimately bonded, and when rehydrated they break apart into an evenly dispersed, fine-grained substrate with ideal air pockets for mycelial gas exchange. Raw sawdust often clumps unevenly, creating anaerobic zones that invite contamination. Hydrated pellets don’t.\n \u003c\/p\u003e\n \u003cp style=\"font-size:13px; color:#555; line-height:1.7; margin:0;\"\u003e\n \u003cstrong style=\"color:#1a1a18;\"\u003eWhy hardwood specifically:\u003c\/strong\u003e\n Wood-loving mushroom species evolved to digest the lignocellulosic structure of hardwood — the combination of cellulose, hemicellulose and lignin that makes up the cell walls.

This process does two useful things for mushroom growers. First, the heat and pressure partially sanitise the raw wood material — reducing the ambient microbial load before sterilisation or pasteurisation even begins. Second, the compressed format means the sawdust particles are intimately bonded, and when rehydrated they break apart into an evenly dispersed, fine-grained substrate with ideal air pockets for mycelial gas exchange. Raw sawdust often clumps unevenly, creating anaerobic zones that invite contamination. Hydrated pellets don’t.\n \u003c\/p\u003e\n \u003cp style=\"font-size:13px; color:#555; line-height:1.7; margin:0;\"\u003e\n \u003cstrong style=\"color:#1a1a18;\"\u003eWhy hardwood specifically:\u003c\/strong\u003e\n Wood-loving mushroom species evolved to digest the lignocellulosic structure of hardwood — the combination of cellulose, hemicellulose and lignin that makes up the cell walls.

It also adds calcium without significantly shifting pH — making it safe to use alongside other additives.\u003c\/p\u003e\n\u003cp\u003eCalcium carbonate (chalk) complements gypsum perfectly. It acts as a gentle pH buffer, helping to counteract the slow acidification that can occur during sterilisation or pasteurisation and throughout colonisation. It also contributes an additional source of calcium, giving your mycelium the minerals it needs to thrive.\u003c\/p\u003e\n\u003cp\u003eTogether, they create a more forgiving, better-structured substrate that colonises evenly and supports healthier, more productive grows.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eApplication Rates:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge bags (2.2 – 2.5 KG substrate):\u003c\/strong\u003e 2 tablespoons \/ 40g per bag\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall bags (1 – 1.6 KG substrate):\u003c\/strong\u003e 1 tablespoon \/ 20g per bag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMix thoroughly into dry substrate before hydrating and sterilising or pasteurising as normal.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHow Much Will One Bag Treat?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAt 40g per bag → approximately \u003cstrong\u003e25 large substrate bags\u003c\/strong\u003e per 1KG of Gypsum + Chalk\u003c\/li\u003e\n\u003cli\u003eAt 20g per bag → approximately \u003cstrong\u003e50 small substrate bags\u003c\/strong\u003e per 1KG of Gypsum + Chalk\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eFrequently Asked Questions:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat mushrooms is Gypsum + Chalk suitable for?\u003c\/strong\u003e\u003cbr\u003eIt's suitable for the full range of commonly cultivated species — oyster mushrooms (all varieties), lion's mane, shiitake, chestnut mushrooms, and most other wood-loving species grown on bulk substrate bags.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it safe to use with sterilised and pasteurised substrates?\u003c\/strong\u003e\u003cbr\u003eYes. Gypsum + Chalk is added to your dry substrate before hydrating, then sterilised or pasteurised along with everything else. Both calcium sulphate and calcium carbonate are heat stable and will not degrade during the sterilisation or pasteurisation process.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use too much? Will it affect my pH badly?\u003c\/strong\u003e\u003cbr\u003eAt the recommended rates, Gypsum + Chalk is well-tolerated and won't push pH to harmful levels. Calcium carbonate is a mild buffer rather than a strong alkali, so it raises pH gently. Stick to the recommended dosing and you'll be in a safe range for most species.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to add any other pH adjusters if I use Gypsum + Chalk?\u003c\/strong\u003e\u003cbr\u003eFor most standard bulk substrate recipes, Gypsum + Chalk at the recommended rate provides sufficient buffering without needing additional pH adjusters. If you're using an unusually acidic substrate or supplementing heavily with high-nitrogen additives, you may want to test your substrate pH after hydrating.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this food-grade?\u003c\/strong\u003e\u003cbr\u003eNo, both calcium sulphate and calcium carbonate used in this blend are not food-grade minerals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow should I store it?\u003c\/strong\u003e\u003cbr\u003eStore in a cool, dry place away from moisture. Keep the bag sealed between uses. Properly stored, it has an indefinite shelf life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it clump itself during storage?\u003c\/strong\u003e\u003cbr\u003eThe calcium sulphate content helps resist clumping in the product itself.
