Superior sterilization process: Our proprietary sterilization process is best-in-class and includes hospital-grade sterility testing. Millet's size maximizes the surface area in which mycelium can grow, and hardwood Oak ensures the moisture content is perfectly distributed.
Works great for at-home hobbyists and large-scale cultivators. Simply insert your needle into the grain bag, inject the liquid culture into the grain, and cover the point of injection with tape. No injection port needed: our team of mycologists designed this product so you can inject a liquid culture syringe directly into the bag without the need for a self healing injection port.



Versatile and easy to use- thick clear plastic construction for durability and easy viewing, built in tub liner no need to use trash bag. Additional features- monotub is 18x10x11 inches inflated and 8x8x1 inches deflated, volume inflated is 35 quarts. Everything you need in a monotub - our monotub/fruiting chamber is equipped with ten built in holes for fresh air exchange; Includes ten plugs for colonization, and ten filters for fruiting stages.
