Liquid culture is a sterile, nutrient-rich broth containing live mushroom mycelium. It is the preferred method for expanding and storing mushroom genetics because it colonizes substrates faster and more reliably than spore syringes. Whether you are a beginner setting up your first mushroom grow or a commercial cultivator scaling production, liquid culture is an essential tool in your workflow.

Our mushroom liquid culture kit lets you turn a single spore or culture syringe into up to 40 syringes of live mycelium — saving you hundreds of dollars compared to buying individual syringes. We also carry pre-made liquid culture syringes in a range of gourmet and medicinal species, grain media for spawning, and the lab supplies you need to work cleanly and efficiently.

Why liquid culture over spores? Spore syringes contain dormant spores that must germinate before colonization begins — a process that adds 1-3 weeks. Liquid culture contains live, actively growing mycelium that begins colonizing immediately on contact with your substrate. The result is faster turnaround, higher success rates, and more consistent yields.

All of our mushroom liquid culture products are prepared in our research-grade lab environment and pressure sterilized for contamination-free results. Pair any of our liquid culture products with our BRF jars, all-in-one grow bags, or grain spawn bags for a complete cultivation workflow.
