Liquid cultures consist of mushroom mycelium suspended in a liquid nutrient broth. Liquid cultures come in 12ml (12cc) syringes. This keeps the mycelium in a sterile environment and allows you to inject the culture for further expansion into new liquid culture or into grain jars for cultivation. Syringes will last for 6+ months if stored in a tightly sealed bag in the refrigerator. We sell a wide range liquid culture syringes of many popular edible and medicinal species from around the world.
