Our \u003cstrong\u003ePre-Mixed Grain Spawn Bags\u003c\/strong\u003e cut straight to the part that matters: just add your measured water, sterilise, and inoculate. No scales, no guesswork, no soaking pots tying up your kitchen for a day.\u003c\/p\u003e\n\u003cp\u003eEach bag contains a pre-portioned amount of clean, Australian-grown grain — choose from Millet, Organic Wheat, or Organic Rye — filled to the exact dry weight needed to reach your chosen finish weight once hydrated. We add 3% by weight of calcium sulphate and \u003cmeta charset=\"utf-8\"\u003ecalcium carbonate to assist with stopping clumping and raising pH levels.  Available in 500g, 1KG, and 2KG finish weight bags, in heat-resistant, filter-patch grow bags ready straight for the pressure cooker or autoclave.\u003c\/p\u003e\n\u003c!-- 3.

Hydration is critical — grain typically absorbs water to roughly 1.8–2x its dry weight during soaking and simmering. Too little water and the mycelium dries out before colonising fully; too much and excess surface moisture invites contamination. Each of our bags is filled to a dry weight calculated against this ratio, so the listed finish weight reflects what you'll have once your measured water is added and absorbed.\u003c\/div\u003e\n\u003c!-- 6.
