Mushroom Strains

Our Species and Strains Library

There are hundreds of Mushroom strains for sale in culture collections around the world today. Our task as a spawn producer is to determine which of those are useful in a cultivation setting. This takes many years of testing. Our library evolves with a quest to provide growers with strains that are stable, vigorous and adaptable to a variety of climates and circumstances. Buy Mushroom Strains below have all been tested and proven in their suitability for cultivators.

Shiitake

We have 13 Shiitake Mushroom Strains for sale which are divided into 3 temperature subdivisions (wide range, cool weather and warm weather) which indicates the temperatures at which they will generally fruit. All strains, regardless of which division it is grouped, grow best at 75°F while getting established (inoculation and spawn run), but actually bear fruit within different temperature ranges. There is usually plenty of overlap between divisions, but it can be safely said that they ALL fruit in the spring and fall, it’s just a matter of when. Growers often utilize all 3 types to get the most production out of a growing season. We recommend a 80:10:10 ratio (wide range:warm:cool) when figuring on how many logs to inoculate from each category. Bear in mind that not all Shiitake varieties respond to force fruiting. The exception to this recommendation would be for indoor growers, who often prefer using strains from the wide range category only. Refer to the chart below for more specific information relating to each Shiitake strain and their division.

Oyster
