    The Blue Oyster Mushroom is celebrated for its swift fruiting period and low-maintenance nature, making it an attractive option for both beginners and seasoned cultivators. This variety is capable of withstanding chilly conditions, even down to 55 degrees, and is frequently incorporated in gourmet cuisine due to its subtle yet intricate flavor. The Blue Oyster has rapidly gained popularity among mushroom enthusiasts, featuring a vibrant blue hue and sizable fruiting bodies. With its exceptionally aggressive growth, the Blue Oyster is among the simplest strains to grow and can produce up to 3 pounds of mushrooms from a 5-pound cultivation kit. To utilize the kit, simply slice and mist the bag daily or position it in a transparent container with a minimal amount of water. The resulting mushrooms not only provide a delectable taste but also furnish health advantages and a visually stunning display.

      One Of Three Kits For First Time Grower

      Pros:
      Cons:
      The Blue Oyster kit was one of the three kits for my first time grow. The kit came well packaged and was ready to take off upon arrival. I placed the kit in a Martha tent on 10/30/22 and the first signs of pinning came on 11/03/22. These babies grew fast and furious, by 11/08/22 they were ready for harvest. First flush produced 24.1 ounces of delicious mushrooms.

      I noticed the pinning for the second flush on 11/17/22. At the time of this review, I have not harvested the second flush.

      Very happy with the quality, shipping speed, and products I've received from Myco Labs.

      Large Yield
