North Spore produces 100% of its spawn at its facility in Westbrook, Maine. Spawn is used by mushroom growers much like seeds are used by gardeners and vegetable farmers. It is the genetic material used to grow mushrooms.
Plug Spawn is best used for smaller log inoculation projects.
100 ct. spawn packs usually are enough for 1-2 logs, 500 ct. packs can reliably do 5-10 logs. The more plugs you use per log, the faster the colonization process will be.
