What yield does milky mushroom give and how is it different from oyster?

Milky mushroom yields are broadly comparable to oyster on a substrate basis, commonly in the range of about 700 grams to 1.5 kg of fresh mushroom per kg of dry substrate in well run units, though beginners get less. The key differences from oyster are that milky mushroom needs a casing soil layer to fruit, prefers warmer temperatures, takes a longer total crop cycle, and gives firm white mushrooms with notably better shelf life. Oyster is faster, cheaper and needs no casing, but spoils quickly. Many growers run oyster in the cooler months and milky mushroom in the hot months so the unit stays productive year round. Treat yield numbers as a planning range and verify locally with your KVK and nearby growers.
