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.

United StatesApology for Yesterday’s Review
I wrote a review yesterday stating that my Golden Oyster mushroom kit did not grow properly. It seems I may have been premature. Later in the day, larger globules emerged that look like cauliflower, and they are beginning to form small yellowish bumps on the surface. I think it might be working, even though it is much slower than the Blue Oyster kit. Please ignore yesterday’s 1 star review.
United StatesNot Growing Properly
I purchased 4 blue oyster kits and 2 golden oyster kits in the past month or so. They have been a huge success, except for the golden. One has grown mushrooms that were very delicate and pale yellowish. The other does not seem to be emerging properly at all. There have been 4 smooth hard white ball shaped protrusions so far, with none of finger-like projections. I will give it a bit more time, as it has only been 2 weeks, but it does not appear to be growing mushrooms. I would gladly give 5 stars to the Blue Oyster kits.
United StatesFirst Golden Oysters - LOVE them
These mushrooms are very delicate and deicious. I've got a small 2nd "bloom" going, so that makes me happy.
United StatesEasy and beautiful
These mushrooms are beautiful! I’ve never seen them before, and thought they would be a fun to try. I’m going to make a mushroom soup tonight with these and the other ones I got as well! Thank you for such a great product, I can’t wait to continue to growing them and trying different recipes.
