Fresh Air RequirementHigh

What is Fresh Air Exchange (FAE)

Fresh air exchange, or FAE is when the air in a growing room, or similar environment like a monotub is exchanged. The use of fans for grow rooms, or “fanning” for monotubs is necessary to eliminate excess C02 in the growing chamber.

In high CO2 environments, the Blue Oysters tends to produce elongated, thick stems and smaller caps. They also generate a significant amount of spores, rapidly filling your growing area with a dense cloud of spores.

Can You Forage Blue Oyster?

Blue Oysters flourish on agar, particularly favouring malt yeast agar. The mycelial growth can be rhizomorphic and eventually becomes thick and fluffy.

What Type of grain spawn is best?

Rye grain serves as the most effective spawn, although sawdust is also a viable option. Some growers have reported higher yields when using straw instead of grain. The spawn has a unique, mushroom-like scent and can be easily broken up for simple bulk substrate spawning.

Most commercial growers use a grain spawn like millet, or rye berries. These are well-known and readily available materials that should be in your mushroom toolkit.

What Substrates Work Best?

Pasteurized straw logs are highly effective for growing Blue Oyster Mushrooms. These logs can yield multiple flushes if contamination is avoided. Supplemented sawdust blocks are another good choice, and definitely the most popular among commercial oyster farms.
