'Popham' elm oyster (Pleurotus ostreatus) is a popular commercial strain that produces highly branched clusters of off-white/tan mushrooms. This strain is very fast growing and yields well in both cold and warm temperatures. 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. 

Directions for use:

For best results, refrigerate upon receipt. 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. If you plan to re-use your needle, sterilize before and after each subsequent use.
