• MILLET SUBSTRATE: Millet is the preferred choice of grain by mycologists because it is less prone to contamination and the smaller grain size allows for more points of inoculation for the same volume of grains as compared to rye berries.
• PERFECT FOR ALL MUSHROOMS: From growing gourmet mushrooms to exotic mushrooms, millet substrate provides the nutrients needed to get your mycelium to produce mushrooms.
• STERILIZED: At Olympus Myco, we take extra steps for the sterilization process in order to make sure the bags arrive to you sterilized and ready to be inoculated.
• SIMPLE TO USE: Whether you are a hobbyist or a professional cultivator, Olympus Myco bags will get your mycelium to spawn with optimal growth and development. Our millet bags can be inoculated via spore injection, grain to grain, or directly transferring mycelium from agar plates.
• INJECTION PORT NOT NEEDED: Inject your liquid culture syringe directly into the bag without the need for a self-healing injection port. Once the liquid culture has been injected, please make sure to cover the injection site with tape.
