  Day 19. Colonization Period UpdatesIn just two weeks (actually, in 10 days) after inoculation, the grain bag with my Antler Reishi was fully colonized.Reishi is considered a slow-growing mushroom (especially during the fruiting stage), but colonization was surprisingly fast. The mycelium was very hungry, aggressive, and rapid — it’s one of the fastest genetics I’ve ever grown! For comparison, here’s my bag with Antler Reishi and Lion’s Mane. Both were inoculated two weeks ago, but the difference is incredible!It’s time to take the next step!
