Golden oyster grow kit.
Golden Oyster (Pleurotus Citrinopileatus)
This kit contains one 5 lb block of colonized substrate. To fruit, cut a 6 inch slit in the bag, cutting into the substrate about 1/4 inch. Spray the opening twice daily. You should see small pins forming after several days. Harvest mushrooms with clean hands just before caps turn convex, continue spraying, and continue harvesting until the block turns moldy. Old substrate blocks make great compost!
