Spawn: The unsung hero of the mycological world! This oat substrate colonized with mycelium is the feisty precursor to beautiful mushrooms. The mycelium has woven itself into a dense, weblike structure throughout the grain and created ready-to-use mushroom spawn. So why purchase grain spawn? Well, it gives you the freedom to grow mushrooms in your own way. Straight from a fruiting block, in a bucket, a  log, or even an old peanut butter jar. It’s a choose your own adventure - mushroom edition. Though, don't get too carried away. Make sure you do your research. Mycology is a tricky business. A sterile environment is always recommended. Once inoculated, your spawn will produce several bountiful, vibrant flushes and you can literally eat the fruits of your labour.

Blue oyster spawn will arrive fully colonized. All you need to do is cut open the spawn bag and inoculate the contents into a substrate.

However, oyster (Pleurotus) species are resilient and can grow from several substrates such as straw, coffee grounds, etc.
