5lb Lignin-Prime HW/Bran Block
$28.00
80/20 hardwood pellet to wheat bran formulation with 2% CaSO₄·2H₂O mineral fortification. Lower nitrogen profile versus Masters Mix — mandatory for Shiitake and Maitake which stall or pin unevenly on high-N substrates. Wheat bran fraction provides lignocellulosic substrate complexity that upregulates laccase activity in wood-decomposing species. Hydrated to 60% field capacity. Sterilized at 118.3°C / 15 PSI for 229 minutes (elevation-adjusted, 4,984 ft). Validated to F₀ ≥ 120. Shipped with Batch ID, Manifest Card, and QR-linked Digital Birth Certificate.

Species Compatibility
Mandatory substrate for Shiitake and Maitake — high-N Masters Mix causes hyphal stalling and uneven pinning on these species. 80/20 HW/bran ratio mirrors the substrate complexity wood-decomposers encounter in nature. Laccase upregulation via wheat bran cellulose is particularly pronounced in Reishi, Turkey Tail, and Chaga. Chaga: slower colonization than oysters — expect 3–4 weeks at 70°F before dense mycelial coverage. Lion's Mane pins aggressively on this formula at 65–70% humidity.

Post-hold, zero-growth confirmed
Every unit is held in incubation after sterilization. No unit ships until the hold window closes with zero contamination evidence. Dates are recorded on the Digital Birth Certificate.
Digital Birth Certificate
Every unit ships with a Manifest Card carrying a QR code. Scan to access the thermal integration log, F₀ value, sterilization parameters, and operator sign-off for your batch. Data is immutable once published.

Altitude Compensation — 4,984 ft
Sterilization parameters compensated for operating altitude. At 4,984 ft, 15 PSI yields 118.3°C — not 121°C. Hold window is product-specific, validated to per-material F₀ targets. Sea-level timing applied at elevation produces inadequate lethality.
Dense, high-hydration substrate requires extended lethality planning for core-mass sterilization at elevation.
