What type of grains do you use for spawn production?

Rye and Millet — both available for all strains.

Rye is popular for its larger kernel size and moisture retention. Millet offers faster colonization and easier break-up. Your choice depends on your substrate and growing methods.

Do you offer organic spawn?

Yes — both organic and non-organic options available.

Organic spawn uses certified organic grains for growers requiring organic certification. Specify your preference when requesting a quote.

Are your strains commercially proven?

Yes — tested through years of commercial production.
