'Harbor Blue' PO1 (Pleurotus ostreatus) is a very productive commercial strain of Blue Oyster from Pennsylvania that fruits dense clusters with dark grayish-blue caps. It produces best in cooler temperatures but also performs well during the warmer months. Averages 1-2 lbs first flush off of 5 lb supplemented sawdust blocks but will also produce off sterilized straw substrate.

Our liquid culture syringes are ~10ml and come with a sterile 16 gauge needle and alcohol wipe.
