Two JUMBO 6 lb sterilized rye mushroom spawn bags with injection port(s)

Description

These bags are tall, so you can just add substrate from the top after it is entirely occupied with mycelium. I can add an extra injection port as well upon request.
Bags are new and freshly made, with 0.2 micron air filter and injection port.
with gypsum, and
water at full capacity, waiting for mushroom culture (not included).
