Blue Oyster (Pleurotus Ostreatus)
Our Certified Organic Blue Oyster substrate is a fast fruiter and a workhorse in terms of fresh mushroom production. These 10lb Oyster blocks can be initiated by cutting a single line along one side of the block or on all four sides for multiple smaller oyster clusters. As with all of our bagged substrate, it's extremely important that the plastic is held tight around the substrate to lock in the moisture inherent in the block for its reserved use in fruit body production. One way this can be achieved is through the use of several rubber bands, keeping the plastic tight to the block and focusing the fruiting to the cuts made. The colder your fruiting temps the darker the shades of blue on the forming caps.
