70/20/10 oak sawdust, peat moss, and coarse vermiculite formulation with 1% CaSO₄·2H₂O and 1% CaCO₃ mineral amendment. CaCO₃ neutralizes the natural acidity of peat moss to achieve a near-neutral pH compatible with a broad range of exotic species. Oak sawdust fraction satisfies the lignocellulosic requirement for Chicken of the Woods and bioluminescent wood-rotters. Peat fraction provides the soil matrix and moisture retention morels require for sclerotia development. 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
Uniquely capable substrate for the three most challenging cultivation categories: morels, bioluminescents, and Chicken of the Woods. The peat/oak matrix provides the soil-moisture interface morels need for sclerotia formation — results are not guaranteed (morel cultivation is notoriously inconsistent) but this substrate represents the best available approximation of field conditions. Chicken of the Woods: oak sawdust triggers the host-wood signaling that initiates fruiting. Bioluminescent species: lean peat/oak profile avoids the nutrient toxicity that suppresses luminescence.

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.

Validation Links
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.
