Trade-offs#

Production lead time, not just shipping. Every order is made fresh — small and medium orders take 1–3 business days to produce before shipping, and orders over 100 lbs can take up to 5 business days to dispatch.
Substrates and live cultures are non-returnable. Damaged or defective items are replaced free of charge, but there’s no satisfaction refund on live goods otherwise. Buyer pays return shipping on eligible items.
US-only shipping. All 50 states covered, but no Canada or international service.
Plug spawn lineup is narrow vs. the culture catalog. Nine plug spawn species (Lions Mane, Shiitake, Reishi, Turkey Tail, Pink Oyster, Pearl Oyster, Grey Oyster, Brown Oyster, Chicken of the Woods) compared to 200+ on liquid culture and plate culture. Log growers shopping by species will hit catalog edges quickly.
