Description
Grow fresh Blue Oyster mushrooms at home with our 5lb ready-to-fruit Blue Oyster Mushroom Grow Kit. This fully colonized gourmet mushroom block is designed for fast, reliable results with minimal setup—just cut, mist, and watch beautiful blue-gray oyster mushroom clusters begin to form.
Blue Oyster mushrooms are one of the most popular gourmet mushroom varieties for home growers because they are fast-growing, beginner-friendly, cold tolerant, and visually stunning. Known for their rich blue-gray caps, tender texture, and mild savory flavor, Blue Oysters are excellent for stir-fries, soups, pasta, tacos, omelets, and sautéed mushroom dishes.
Each kit is made with a 5lb pre-colonized substrate block using vigorous Blue Oyster mushroom mycelium. Unlike starting from spores or grain spawn, this ready-to-fruit grow block arrives already colonized, helping simplify the process and shorten the time between setup and harvest.

Appearance, Flavor & Cooking Uses
Blue Oyster mushrooms produce dense clusters of fan-shaped caps with blue-gray coloring that often fades slightly as the mushrooms mature. Their texture is tender yet meaty, making them a favorite for both home cooks and gourmet mushroom growers.
In the kitchen, Blue Oysters have a mild, earthy, savory flavor with subtle nutty notes. They cook beautifully with garlic, butter, olive oil, soy sauce, fresh herbs, onions, pasta, rice, eggs, soups, and stir-fry dishes. For best texture, sauté until lightly browned and avoid overcrowding the pan.
Best Growing Conditions
- Temperature: 55°F–80°F, with cooler conditions helping preserve deeper blue coloration.
- Humidity: Mist regularly to keep the fruiting area from drying out.
- Fresh Air: Blue Oysters need good fresh air exchange for healthy cap development.
- Light: Indirect natural light or ambient room light is usually sufficient.
- Location: Kitchen counters, shelves, grow tents, or clean indoor areas work well.
Pro Tip: Improve Humidity for Better Results
Blue Oyster mushrooms love humidity. For easier moisture control, pair this kit with our Tabletop Humidity Tent — available as a low-cost add-on when bundled with any gourmet mushroom grow kit. It helps maintain a more stable fruiting environment and reduces the need for constant misting.

Let customers speak for us
I was getting alot of contam with northspore boomr bag strait garbage company. Contamination central at northspore almost everything contams. I tried a couple other companies then tried this blackcow. Its black gold Texas T the biggest dummy in the world will get massive flushes with this. The grain bags are awesome too and sterilized right. I went 14/14 on the grain bags. Midwest know what they are doing and even the packaging is next lvl everything double bagged. I only buy from midwest it's worth every cent
It's been several days since the Ecosphere arrived and I set it up, and I'm still amazed at all I got for the price: heater, fan, humidifier, two plug-in timers, two foil trays, and, of course, the five-tier tent with shelves and the plastic cover. Oh, and the LED light strip and the round air filters. It's everything I need right now, and I've started the growing process. It's a crazy good deal for the price. I'm new to mushroom growing, and I'm thrilled that I bought this setup as a start. Just plain wonderful.
Fast and easy colonization! These grain jars showed growth after just 10 days. My previous efforts with the all-in-one bags are taking MUCH longer but also working. Thank you Midwest Grow Kits 🙏
I love the people and the products. The people at MWGK clearly care about the integrity of the community they serve.
The monotub works amazing only had it a couple of weeks and about to have second harvest I used AIO grow bag for first flush and move to tub for second and its great not having to watch 24/7. Thanks Midwest
Four days after mixing grain, Select substrate, and the Midwest horse manure booster - the results speak for themselves.
It has everything you need for a fast, large flush success with fewer moving parts than a standard monotub. It is a surprisingly versatile option for more advanced students. Pic is 5 grain jar at 8 days. GT LM This is where I shop, now.
Rich, perfectly field-wet, sterile and it is perfect for those many varieties that won’t thrive quite as well in Bulk Substrate and Casing Mix, which I’ve seen as best for psilocybes/cyanescens. I’m using it for the first time with Lions Mane and King Trumpets. So far so good, 7 days and primordial and pins are starting to flourish. It drains better and is lighter than MGK’s Bulk Casing and Substrate. Great product.
Love the heater and how even and exact it heats. I set mine to 76 degrees and my room fluctuates from 64-75 and it holds solid at 75 degrees. I used a probe thermometer to double check the substrate level temp and its exactly 1 degree less than the heater setting. Another tip, I only needed to use the round monotub thermometer to check my humidity levels every so often. I would leave a filter disk on that hole instead of the thermometer. The only time it came in handy was after my first flush when humidity started to drop. I was able to use that gauge and check whether I needed to mist. Overall great kit and worth the money!
Ive bought mutiple jars before i came up with my own recipe, every jar produced healthy cultures, even if ones damaged in shipping they replace immediately, highly recommend
Very small chance that you get a contaminate you already had it and you’re either culture spores etc. their stuff is 100% sterile every time 100% of the time everything is viable never had a problem been shopping with them for sometime
It’s very good product and I highly recommend it to everyone.👏👏👏
I love my magnetic stir plate it works great for Liquid culture jars.
My bag had a slow start, but excellent finish. Oak Ridge.
Great product for my cannabis best deal around arrived fast thank you Midwest grow kits definitely will be purchasing again
