Premium Blue Oyster Mushroom Fruiting Block Grow Kit – 5 lbs

Enjoy fresh, gourmet mushrooms at home with our Premium Blue Oyster Mushroom Fruiting Block Grow Kit. This beginner-friendly indoor kit makes mushroom growing simple, fun, and rewarding—no prior experience or special tools needed.

Each kit arrives fully colonized and ready to fruit. Just cut an “X” into the plastic, mist with water 2–3 times daily, and watch your mushrooms flourish within days. The Blue Oyster variety is known for its rich, savory flavor and meaty texture, making it a favorite for stir-fries, soups, and sautés.

Our fruiting block kits are 100% guaranteed to grow, chemical- and pesticide-free, and made with organic substrate for clean, safe, and delicious results. With proper care, each kit can yield up to 3 pounds of fresh Blue Oyster mushrooms, bringing farm-to-table freshness right to your kitchen counter.

Why It Costs Less

This budget-friendly option includes the same high-quality fruiting block as our boxed kits—but without the branded cardboard box or spray bottle. By simplifying the packaging, we pass the savings directly to you while maintaining the same exceptional quality and performance.
Instructions

1. Slice an 'X' into the plastic underneath with a sharp knife.

2. Fill a spray bottle with water and spray where you sliced your 'X' at least twice a day - more if you live in a dry climate. You should give your kit 8 -12 sprays each time you mist it.
(If mushrooms start to grow but dry up and die, your growing conditions are too dry and you should make a humidity tent.)

3. Place your grow kit in a warm, humid part of your home and out of direct sunlight. It takes 5-14 days for 'pins' or 'baby mushrooms' to form.

4. Harvest 4-5 days after pin formation.

Did you know mushrooms can double in size every 24 hours once they start fruiting?

    How to Make a Humidity Tent?

    If you live in a dry climate, it's a good idea to cover your kit with a humidity tent to help keep moisture levels higher.

    1. Take a trash bag or other large loose bag and cut plenty of ½ inch holes throughout it. THIS IS IMPORTANT: Mushrooms breathe in oxygen and exhale CO2 just like we do. They will suffocate and abort if there is not enough airflow. 
    2. Gently place the bag over your block and mist the inside of the bag every day. When you start to see baby mushrooms form (pinning), you can remove the bag and keep misting the block. 

    Pro Tip: You can also use a clear plastic tote with holes cut in it instead of a plastic bag. This is a great option if you are going to be ordering recurring mushroom grow kits in the future. 
    What is the proper Storage for your Growing Mushroom?

    We recommend using your mushroom grow kit upon arrival for best results. If you're not ready to use your mushroom growing kit immediately, it can be stored in a cool dry place, out of direct sunlight, for up to 6 months. Keep in mind that mushroom mycelium is alive!

    Lion's Mane, Blue Oyster, Golden Oyster, and Gray Oyster mushroom grow kits can be refrigerated for up to 6 months (preferred storage method if possible).

    PINK OYSTER MUSHROOMS: Do not refrigerate pink oyster mushroom grow kits. They can be stored in a cool dry place, out of direct sunlight, for up to 6 months.
    What's the Mushroom Growing Kit Guarantee?

    We 100% guarantee your fruiting block with grow mushrooms orwe send you a new block for free(or refund your money if you really don't feel like trying again). 95% of the time a customer can't get one of our blocks to produce mushrooms its due to low humidity in the growing environment. We highly suggest you make a humidity tent to maximize the chance of producing a large flush of mushrooms to harvest.
