'Harbor Blue' Oyster 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 sealed in a plastic sleeve with a sterile 16 gauge needle and alcohol wipe.

About liquid culture:

Liquid culture is mycelium suspended in a nutrient-rich medium. Syringes are beginner-friendly and ideal for those looking for an easy way to inoculate grain bags and jars. 

Using liquid culture:

Syringes should be inserted into a self-healing injection port. Always handle using sterile technique and shake thoroughly before use. We recommended inoculation in either a still air box or flow hood to reduce the possibility of contamination. We also recommend sterilizing your needle before use.
