Mario’s Mushrooms™ All-In-One Sterilized Mushroom Grow Kit | Complete Bag with Grain & Substrate

The easy way to start a mushroom project at home.

The Mario’s Mushrooms All-in-One Grow Kit arrives pre-sterilized, sealed, and ready to inoculate. Each bag is packed in a clean environment with a balanced layer of nutrient grain spawn topped with premium substrate—measured to create reliable conditions for fast colonization.

No extra tubs, pasteurizing, or guesswork. Just inject through the self-healing injection port, then let the built-in filter patch handle gas exchange while helping block contaminants. Ideal for beginners and a time-saver for experienced growers.
