Please note, we prepare the grains on Monday morning and ship them out on Thursday. To ensure the earliest arrival, please place your order before Friday @2pm

Please note replacement policy, if bags get contaminated during shipping we will send out new bags, please note if you dont contact us within 1-2 weeks after receiving with clear photos we will not send a replacement 

as soon as they arrive, unbox them and store somewhere cool and dark below 24deg

We hydrate the grain in gypsum fortified water for 24 hours, then sterilize for 1.5 hours @ 15PSI

Simply inoculate each 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

You can fruit in vitro in the bag or in a fruiting chamber as you would a standard substrate cake. Nothing could be easier. Just inoculate and wait.

For larger grows the Rye Grain bags can also be used as spawn for a bulk substrate.

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

These bags are suited for beginner and advanced mycologists.
