All in One Mushroom Grow Bag

All-in-One Mushroom Grow Bags

An all-in-one mushroom grow bag combines sterilized grain spawn and the growing substrate in a single sealed bag, with a self-healing injection port and a filter patch built in. You inoculate through the port, let the bag fully colonize, then fruit your mushrooms right inside it. There is nothing to mix, sterilize, or transfer, which keeps the process simple and the contamination risk low.

Out-Grow offers 22 different all-in-one mushroom grow bags, the widest selection available anywhere, including our trademarked Inoculate and Wait® substrate system. We have been producing all-in-one mushroom grow bags since 2014, longer than nearly any seller in the industry, and we still pack more substrate per bag than the competition.

How to Choose Your All in One Mushroom Grow Bag

Choosing the right all-in-one mushroom grow bag comes down to the species you want to grow. Manure-based all-in-one mushroom grow bags suit dung-loving species, while wood-based all-in-one mushroom grow bags are formulated for wood-loving mushrooms like lion's mane, shiitake, and oyster. We also offer grain-specific options including golden grain, red milo, white milo, brown rice flour, and our Mega Mix blend, in standard and mini sizes from small test grows up to 10 lb bulk bags.

Every all-in-one mushroom grow bag is fully hydrated, sterilized, and ready to inoculate on arrival.
