Why Out-Grow Liquid Cultures Are the Best

Our liquid cultures contain vigorous, actively growing mycelium suspended in a sterile nutrient solution, ready for immediate use. Produced by professional mycologists in a controlled laboratory environment, these liquid cultures deliver faster colonization, reduced contamination risks, and more consistent results than spores or other inoculation methods. Since 2010, we've perfected our techniques to provide the cleanest, most reliable mushroom liquid cultures on the market.
