Oyster mushroom seedlings for the Mushroom Garden

The package contains 25–33 grams of oyster mushroom seeds for the Growkit , which you just need to mix with fresh coffee grounds.
 If you don't start growing right away, don't forget to store the seeds in the refrigerator and use them no later than 3 months from the date on the package.
 Next, you'll only need a Mushroomarium, coffee grounds, and a little care.
