Bags are 100% sterile and processed in our commercial autoclave

core bag temps are monitored during cooking to ensure they hit the correct temperature for the correct time

they are then sealed in our  custom class 100 mushroom laboratory and we place open nutrient-filled agar plates around the room to ensure there’s no chance bags could be contaminated while sealing

directions of use

Unbox as soon as they arrive and rest for 1 week, if no signs of problems show up inoculate (sometimes during shipping problems can happen)

email photos within 2 weeks of receiving if you have any issues before inoculation and we will replace any bags affected during shipping


Simply inoculate each 1.8kg bag with 2-4 cc of your gourmet mushroom spore solution or 5-8 cc of liquid culture and let it grow.

If you have a flow hood, you can do agar and grain transfers

Nothing could be easier. Just inoculate and wait.

Rye Grain bags are great to use as spawn for bulk substrate.

Normally from inoculation to fruiting is around 4-5 weeks.

These bags are suited for beginners and advanced mycologists.
