Cascadia Mushrooms

Who it’s best for#

Cascadia Mushrooms is a good fit for Pacific Northwest growers, gift buyers, and anyone who wants USDA-certified organic kits and plug spawn from a founder-run farm with real operational history. It’s one of the longest-running retailers in the directory — Alex Winstead started the farm in his rented Bellingham basement in 2005 after finishing a mycology degree at Evergreen State College, built the permanent North Bellingham facility in 2010, and still runs it today. The farm also supplies two dozen local restaurants, grocers, and farmers’ markets, so the retail storefront is attached to a working commercial operation rather than being the entire business.

The catalog leans toward finished products and log growing rather than the DIY sterile-lab stack. If you want grain spawn in jars, liquid cultures, or bulk substrate, you’ll need to look at Out-Grow or North Spore instead.

What they do well#

Cascadia’s kit lineup is unusually diverse. Most competitors stick to the standard blue oyster, lion’s mane, and shiitake trio, but Cascadia sells 10 species at a flat $30 — including Cosmic Queen Oyster, Italian Oyster, Elm Oyster, Coral Tooth, and a Reishi Antler kit. That variety matters if you want to experiment beyond the usual gourmet starter species without hunting across multiple suppliers.

The USDA Organic certification applies to everything they sell, and the About page is specific about what that means in practice: no pesticides, spawn and grain sourced from other organic growers where possible, and all plastic recycled through a Puget Sound-based processor. If you’re growing for sale or supplying a farmers’ market stall of your own, the provenance is meaningful in a way it isn’t for most direct-to-consumer suppliers.

Plug spawn is the other standout. Each $18 bag contains 100+ plugs — enough to inoculate 3–5 logs 3–4 feet long — and Cascadia sells the two accessories you actually need alongside it: sealing wax ($5) and a plug tool kit ($20). For small-scale log cultivation, you can build an entire starter project from one cart.

The tinctures are also formulated more transparently than most. Dual-extraction, concentrated to 333 mg of mushrooms per mL at a 1:3 ratio, from organically-grown or ethically wild-foraged US sources. That’s a level of specificity most tincture brands don’t publish.

Where they fall short#

The catalog is narrow if you’re a DIY grower. Cascadia sells plug spawn but no grain spawn, no sawdust spawn, no liquid cultures, no agar plates, and no bulk substrate. This is a kit-and-log supplier, not a cultivation lab supplier. If your workflow involves inoculating your own grain or pouring agar, you won’t find what you need here.

Shipping is US-only and narrower than it looks. Standard mainland US shipping is free at $150, but Alaska, Hawaii, Puerto Rico, and US territories all incur additional fees, and Canada isn’t offered at all — the country isn’t even selectable at checkout. Canadian readers and non-mainland US readers will need to look elsewhere.

The 4-day shipping window is another small friction. Cascadia only ships Monday through Thursday, so orders placed late in the week sit over the weekend before dispatching. It’s a reasonable policy for live mycelium — better than shipping a kit into a weekend transit delay — but worth planning around.
