Description

Pearl Giant Oyster (Pleurotus ostreatus sapidus) Gourmet. (is a giant species of Blue Pearl Oyster), Side fruiting- Fruiting temp: 20ยฐ-30ยฐC

Rootlab is currently transitioning from Millet to Rye, so some spawn may be delivered on organic Rye instead of the advertised Millet.

Check out all the variety of Grain Spawn on offer.

Grain-spawn mycelium, Gourmet and medicinal strains are available fully colonised for mushroom cultivation, made with excellent commercial-quality culture.
Ready-to-go bags! Cut your bag open, add to your pre-sterilised or pasteurised substrate or sterilised grains and allow it to colonise completely.
GENERAL GRAIN SPAWN INFORMATION-
  • Fully colonised and contaminant-free
  • 100% reputable Millet or Organic Rye
  • Calcium Carbonate added for supplementation
  • Gypsum is added to prevent grains from clumping together
  • It comes with a bit of Sawdust/ Manure or Straw to expose mycelium to its final substrate and reduce the lag period.
  • Grains are autoclaved and prepared at field capacity
Method to use:-
  • Add at least 5-20% grain spawn in your substrate. The amount of spawn you add depends on whether your substrate is sterilised or pasteurised, your experience level, and the type of mycelium used(Reishi and Oysters require less spawn than shiitake, Almond or Portobello).
  • The grains can also be transferred to more Sterilised Grain bags and expanded further.
  • Suppose you are using pasteurised substrate instead of the sterilised substrate. In that case, a higher grain spawn rate may lead to fewer chances of contamination, as higher grain spawning leads to faster colonisation.
Bags are assured 100% contaminant-free due to their sterilisation process of 2h at 15psi in a commercial autoclave. Moreover, we inoculate and heat-seal our bags before a 0.3-micron laminar flow hood. These strains are vigorous and fast-growing, reducing the chances of contamination once the substrate is added.
