Golden Oyster Mushroom Grow Kit

Retail orders are typically shipped within three business days of purchase (likely sooner). We ship products out Monday – Thursday. Anything purchased after 4pm PST Thursday will be shipped the following Monday. Please note that overnight and/or expedited shipping times refer to the time something takes to ship according to the shipping method, rather than the time it takes to send an order.

If a package is returned due to an incorrect address provided during the checkout, we reserve the right to charge additional shipping. Requests for shipping information can be sent to info@cascadiamushrooms.com.

We send out orders as soon as possible. Please keep in mind that any mushroom kits or spawn will need to be protected from extreme cold and heat. Mycelium (the base of the mushrooms) is alive and should not be left out in the sun or snow. Please be ready to accept your order as it arrives.

What are the key ingredients to growing mushrooms successfully?

High humidity, indirect light, a good amount of fresh air, and temperatures ranging from 55-75 degrees F. For more information, check out our page on growing mushrooms.

When should I start my mushroom kit?

All mushroom kits should be started within a week of receiving them. If you can't start your kit right away it can be safely refrigerated for up to 4 weeks.
