Adding nitrogen-rich material — soy hulls, lupin hulls, bran — dramatically increases what mycelium can pull out of a block, but it feeds moulds and bacteria just as readily.

Each bag is autoclaved at 121°C \/ 15 PSI, with hold time scaled to the bag's finished weight so heat penetrates fully to the core of the substrate mass rather than just the outer layer. We add 3% by weight of calcium sulphate (gypsum) and calcium carbonate (chalk) — gypsum improves substrate structure and stops the mass compacting as mycelium runs through it, and chalk buffers pH toward the slightly alkaline range gourmet species prefer, quietly disadvantaging the bacterial and mould competitors that favour acidic conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- ============ SECTION 6: APPLICATION \/ USE GUIDE ============ --\u003e\n\u003ch2 style=\"font-size: 22px; font-weight: bold; color: #2f3b26; margin: 0 0 16px; border-bottom: 2px solid #dfe3d3; padding-bottom: 8px;\"\u003eHow To Use\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 0 0 16px; font-size: 14px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background: #2f3b26;\"\u003e\n\u003cth style=\"color: #ffffff; text-align: left; padding: 10px 12px; font-weight: 600;\"\u003eStep\u003c\/th\u003e\n\u003cth style=\"color: #ffffff; text-align: left; padding: 10px 12px; font-weight: 600;\"\u003eWhat To Do\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background: #f7f7f0;\"\u003e\n\u003ctd style=\"padding: 10px 12px; border-bottom: 1px solid #e3e5da; white-space: nowrap;\"\u003e\n\u003cstrong\u003ePrepare\u003c\/strong\u003e \u003cspan style=\"display: inline-block; background: #5c7a4a; color: #fff; font-size: 10px; font-weight: bold; border-radius: 4px; padding: 2px 6px; margin-left: 6px;\"\u003e1\u003c\/span\u003e\n\u003c\/td\u003e\n\u003ctd style=\"padding: 10px 12px; border-bottom: 1px solid #e3e5da;\"\u003eWork inside a still air box or in front of a flow hood, in a room with no air movement.

This product is intended for mushroom cultivation only and is not for human or animal consumption. Keep away from children and pets. If a bag arrives torn, punctured, or with a damaged or wet filter patch, photograph it and contact us before spawning — sterility cannot be assured once the seal is compromised. Sterile technique at the point of spawning is the grower's responsibility; a sterile bag opened in a dusty room won't stay sterile.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- ============ SECTION 8: SPECIFICATIONS ============ --\u003e\n\u003ch2 style=\"font-size: 22px; font-weight: bold; color: #2f3b26; margin: 0 0 16px; border-bottom: 2px solid #dfe3d3; padding-bottom: 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003cul style=\"margin: 0 0 28px; padding-left: 0; list-style: none;\"\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eFinished weight:\u003c\/strong\u003e 2.2KG per bag, hydrated to field capacity\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eMasters Mix:\u003c\/strong\u003e 50% Australian hardwood sawdust, 50% Australian soy hull pellets\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eMasters Mix (Lupin):\u003c\/strong\u003e 50% Australian hardwood sawdust, 50% Australian lupin hull pellets\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eHardwood \u0026amp; Organic Wheat Bran 80\/20:\u003c\/strong\u003e 80% Australian hardwood sawdust, 20% organic wheat bran\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eHardwood \u0026amp; Organic Wheat Bran 90\/10:\u003c\/strong\u003e 90% Australian hardwood sawdust, 10% organic wheat bran\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eAmendments:\u003c\/strong\u003e 3% by weight calcium sulphate (gypsum) and calcium carbonate (chalk), all variants\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eBag type:\u003c\/strong\u003e Heat-resistant polypropylene grow bag with 0.2 micron breathable filter patch\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eSterilisation:\u003c\/strong\u003e Autoclaved at 121°C \/ 15 PSI, hold time scaled to bag size\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eSpawn rate:\u003c\/strong\u003e 10–20% by weight — 220g to 440g of grain spawn per bag\u003c\/li\u003e\n\u003cli style=\"padding: 6px 0; font-size: 14px;\"\u003e\n\u003cstrong\u003eInoculation:\u003c\/strong\u003e No injection port — open, add grain spawn, seal and shake.
