What's in the box
- 6 × 5 lb bags of Willy's Blend manure-based substrate (30 lbs total)
- Pasteurized and hydrated, sealed and ready to use
What growers report
- Strong, fast colonization
- Thick, resilient mycelium
- Good water retention without a muddy texture
- Reliable fruiting from a forgiving substrate
How to use it
- Start with fully colonized spawn. Grain spawn bags or jars should be completely white before you spawn to bulk.
- Break up the spawn. Massage the bag or shake the jar until the grain separates into loose kernels.
- Open the substrate. Crumble any clumps so the substrate is loose and even.
- Mix it in the tub. Combine spawn and substrate evenly in a clean monotub or tray, then level and lightly press the surface.
- Colonize, then fruit. Cover and leave it undisturbed until the surface is colonized, then introduce fruiting conditions.
Spawning to bulk: break up the grain and mix it through the substrate.
How much spawn per bag?
- 1 to 1.5 grain spawn bags per 5 lb bag
- About 3 quick-colonizing 24 oz jars per bag
- About 6 half-pint jars per bag
- For the full 6-pack, plan on roughly 6–9 grain spawn bags
