All-in-one mushroom grow kits are designed to simplify the process of growing mushrooms. These kits typically include everything you need to start cultivating mushrooms, including substrate which is often sterilised CVG (coco coir, vermiculite, gypsum) and rye grain. Simply inject your spores or liquid culture into the self healing injection port and wait for mycelium start to colonise the grain. Once the substrate has fully colonised, it can the be put into fruiting conditions. Because the substrate and grain are sterilised together, the risk for contamination is greatly reduced.
