Fully hydrated and sterilized ready to inoculate rite out of the box! Out-Grow only uses certified organic whole oats to make this wonderful mushroom substrate. Each bag has 3 quarts (3lbs) of hydrated and sterilized whole oats. The mushroom grow bag has a self healing injection port and a 5 micron filter patch for proper gas exchange while keeping out contamination's. Whole oats are nutritionally optimal for mycelia biomass production. Simply inoculate with 6cc of your favorite gourmet mushroom culture and allow 14 to 21 days in room temperatures for proper germination. Normally it will take 4 – 6 weeks from the time of inoculation until full colonization. Once your whole oats mushroom substrate is fully colonized this bag can inoculate up to 15lbs of bulk substrate!


Enjoy the fun of the hobby and delicious fruits of mushroom cultivation with Out-Grows sterilized mushroom substrates!

Moisture content looks great and shipping was only a few days! One week after inoculation which I made sure to be extremely sterile and I'm seeing small growth in both bags.
