This species generates a heavy yield with many mushrooms. Large caps and short stems can be achieved with low carbon dioxide levels, creating the optimum mushroom. Mushroom bodies may last up to 14 days after harvest in the fridge.
Our grain formula contains the optimum levels of nitrogen required for quick growth of mycelium as well as a high number of inoculation points. Weights of bags are approximated.
We aim to have all our grain spawn ready to dispatch whenever there is an order, but because it is a live mycelium sometimes dispatch may take longer. We will get in touch if this is the case.
Note: We break all of our grain spawn before shipping for your convenience. The grain is fully colonised and can be used as soon as you receive it. The described information has been tested thoroughly and the optimum conditions have been listed. Because of this, results may vary if the appropriate conditions are not met.
Blue Oyster Grain Spawn
Species: Pleurotus ostreatus
Recommended substrate: Hardwood/straw (wheat)
Fruiting duration: 4-6 weeks
Yield: Approx. 200-250g of fresh mushrooms per kg of our recommended wet substrate (1st flush); pre-inoculation
Inoculation % of wet substrate: 2-10%; higher inoculation % leads to a shorter incubation period. Do not exceed 10%.
