Oyster Mushroom Farming

Innovation Education Creating Opportunity

(Champions' Club / Site Map / YouTube)

Oyster mushrooms are a relaible and productive crop we can produce inexpensively without sunlight. Local biomass supplies will be evaluated to manufacture grow blocks. This allows us to use small amounts of land efficiently. The model of farm we are currently planning on is described in the following link(s):

We will be culturing mushroom spawn for our own use and to supply local farmers without laboratory facilities. Some typical varieties of oyster mushroom are here:

* **Blue Oyster Amycel 3015:** This quick-growing blue oyster strain will fruit in a wide range of temperatures between 50°F – 75°F, and it will produce a large yield. The fruiting clusters have large caps that range in color from blue to white, depending on the temperature the mushrooms are grown in and the stage of life.
* **Golden Oyster:** Pleurotus cornucopiae, often grown from sawdust spawn, is luminous citrine yellow mushroom with a tangy flavor that tolerates higher temperature ranges.
* **Pink Oyster VDE-1:** This extremely-fast colonizing pink oyster has the ability to grow on a wide range of substrates between 60°F – 85°F, and it produces a medium yield of mushrooms with pink to red fruited bodies. Note that storage and shelf life is limited for this mushroom. This mushroom cannot survive temperatures below 40°F, so take that into account before trying this strain.
* **White Oyster Elm A:** This white oyster aggressively colonizes its substrate and has the ability to combat contaminants. It prefers to fruit in temperature in the 55-80 degrees F range. The caps are large, and the mushroom can fruit singularly or in clusters with large individual mushrooms.
* **Yellow Oyster AM1:** This strain produces a vibrant yellow oyster mushroom when grown in temperatures between 60°F – 80°F, and is responsible for a medium to high yield. The caps are typically small and numerous, and the stems are large and edible, too.

Info on spawn types above is from: https://fungially.com/growing-oyster-mushrooms-strains/. We will be exploring higher temperature strains so that our passive cooling systems can maintain desirable growing temperatures (25°C to 35°C - 77°F to 95°F). Seasonal grow cycles and efficient secondary application of air conditioning through joint HVAC systems is also a design possibility. Development of high temperature strains suitable for the tropics is a viable medium term goal and an excellent research project for our students. Additional information in the link(s) below:
