Mushroom Substrate Recipes
Mushroom substrate recipes are grouped here by material and growing method. Read each guide for its preparation scope and limitations. Historical reference recipes are not owner-verified trials, and a prepared product should be used according to its own instructions.
Recipes are grouped by material. If you're not sure which material you need, start with the complete substrate guide.
Manure-based
The standard for Agaricus — white button, cremini, portobello — and dung-loving species generally. Higher nitrogen than straw or wood.
Buy it ready: 1 lb, 5 lb, 25 lb, or the horse manure and straw blend.
Don't forget the casing. Agaricus species will not pin without a casing layer. This is the most common reason a button grow colonises perfectly and then produces nothing.
Straw
Cheap, fast, forgiving. The default for oyster and wine cap.
Buy it ready: pasteurized straw, 5 lb.
Hardwood and sawdust
Slower than straw, higher yielding. What the wood-lovers want: lion's mane, shiitake, reishi, maitake, chestnut, enoki.

Grain spawn
Grain isn't a fruiting substrate — it's the carrier you colonise first. Must be pressure sterilized, never pasteurized.
Buy it ready: grain bags and grain jars in rye, popcorn, milo, millet, oats and multi-grain.
Before ordering, compare sterilized grain bags and colonized grain spawn. For a prepared bag, follow the 1lb rye grain bag manual or 1lb multi-grain bag manual for that exact product. For receiving materials, browse prepared mushroom substrates and casing soil and match the supplied stage to your method.
Coir, vermiculite and BRF
Consistent, easy to hydrate, low contamination risk. Popular for small indoor grows.
Buy it ready: BRF and vermiculite jars or the 12-pack.

Make it or buy it
Choose between DIY and prepared mushroom substrate by comparing the work your method requires with the work included in the supplied product. These guides distinguish reference formulations from validated procedures; they do not establish that every recipe was tested by this store.
