    SAVE YOURSELF $$$ AND TURN ONE SPORE SYRINGE INTO 40 or more! Use this to maximize your next growing project. Our Premium XL Liquid Culture Kit saves you time and money on your grow. There are multiple ways to use a liquid culture. You can simply inject 3-5 cc's of your favorite spores in the culture jar or an even better way is to start your spores on an agar plate, then transfer the best looking mycelium to the liquid culture. Either way in a few days it will be ready to inject into any substrate jar or spawn bag. It will cut down your colonization times by over a week! 

    How it works

    Our proprietary blend of sugars and fermented grain proteins provide the perfect liquid environment for mushroom spores to germinate and turn into liquid mycelium (the first stage of mushroom growing). Simply inject 3-5cc’s of your favorite spores into the jar, incubate at 76-82 degrees for 4-5 days and a white cloud of mycelium will start to form. Stir the jar using the included magnet and magnetic mixing bar to break up the mycelium. Insert the large 60cc syringe back into the jar and fill it up. Now you are ready to inoculate a large quantity of substrate jars or spawn bags! Once the jar is full of mycelium it can be stored in the fridge for up to 3-4 months and used as needed! Liquid cultures should be used within 2-3 weeks of receiving and stored in the fridge prior to use. Please open and check this product upon receiving to ensure no shipping damage or leakage. We guarantee our liquid culture jars & will replace if there are any issues!
