Strain & Substrate Selection
This section focuses on understanding which substrate Blue Oyster Mushrooms prefer and how to determine the materials to consider for mycelial growth, aka, THE SPAWN RUN [colonization].
We'll also take a moment to examine the different pest and disease concerns for this specific strain.There are many factors to consider when choosing the right substrate.
Here are a few forms of substrate that can cultivate [blue oyster] mushroom growth:
Bulk Substrate/agricultural waste [straw, wood logs, cotton waste, sawdust, cardboard]
Liquid Substrate [coconut water, karo-syrup, water mixture]
Grain Substrate [millet, wheat, rye]
Tissue Culturing and Agar Plates [seaweed, potato-dextrose]
Next, one must consider how they wish to treat the substrate to ensure a sterile growing environment. For bulk and grain substrates, the choice is between pasteurization or sterilization. Liquid substrate requires uncontaminated liquid, clean water, and the proper sugar content level.
Another key note to bear in mind is the types of pests and diseases that can affect or attack our growing fungi. Mites, flies, green mold, bacterial rot, and brown spots, are all potential dangers to growing mycelial spawn and can be brought on by various factors along different stages of cultivation.
Often, these issues are a direct result of variations in humidity and temperature, the water content of the substrate, overgrowth of competing bacteria, and insufficient border control of inoculation containers and fruiting rooms.
