These liquid cultures can be injected directly into a wood-based substrate bag with injection port, or into grain bags/jars for expansion and spawn-to-bulk transfers.
NOTE: Wood-loving species can be added to wood substrates without the need for a grain transfer – to get more mileage out of your culture, inoculate grain and add to your substrates in a still air box or flow hood at a 5-10% grain to substrate ratio.
Storage
For best results, store your liquid culture in the refrigerator until ready to use. If you plan to use the culture within 1-3 weeks, refrigeration is not necessary. When refrigerated, liquid cultures can remain viable for up to 6 months. Do not freeze, as freezing may damage the mycelium. Keep out of direct sunlight and avoid exposure to heat.
Liquid Culture Instructions
PREPARE YOUR ENVIRONMENT: Wash your hands and put on a pair of disposable gloves. Use a laminar flow hood or a still air box for best results. Thoroughly clean your workspace and gloves with 70% isopropyl alcohol.
DISINFECT PACKAGING: Spray syringe and needle packaging thoroughly with 70% isopropyl alcohol.
ASSEMBLE SYRINGE: Remove the cap from the liquid culture syringe and attach the needle, twisting to lock it in place. Leave the guard on the needle until you’re ready to inoculate.
DISINFECT GRAIN JARS OR BAGS: Disinfect items to be inoculated with 70% isopropyl alcohol.
INOCULATE: Carefully remove the needle guard and inject the culture. For best results, use a new needle for each injection or flame sterilize between uses.
For smaller grain jars, use 3-5mL of liquid culture per jar.
For larger bags of grain or wood substrate (3 lbs+) use 10mL of liquid culture per bag.
