made-to-order
A$20.00
Out of stock
Ready-to-go bags! Simply cut your bag open, add to your pre-sterilised or pasteurised substrate allow it to colonise fully.
GENERAL INFORMATION
500gm/1kg/2kg of grain spawn of your choice in mushroom bags with breathable port
Fully colonised and contaminant-free
Grains
Calcium Carbonate added for supplementation
Gypsum is added to prevent grains from clumping together
It comes with a little Sawdust to expose mycelium to its final substrate and reduce the lag period.
Grains 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 if your substrate is sterilised or pasteurised, your experience level, type of mycelium used (Reishi and Oysters require less spawn compared to shiitake or Almond or Portobello).
The grains can also be transferred to more Sterilised Grain bags and expanded further.
If you are using pasteurised substrate instead of the Sterilised Substrate, a higher grain spawn rate MAY lead to fewer chances of contamination as higher grain spawn leads to faster colonisation.
Bags are assured 100% contaminant-free due to their sterilisation process of 2.5h at 15psi in a commercial autoclave. Moreover, we inoculate and heat-seal our bags in front of a 0.1 Micron laminar flow-hood. These strains are vigorous and fast-growing, reducing the chances of contamination once the substrate is added.
