Why we love them:
Golden oyster mushrooms are aromatic, delicate, and delicious. They also have a hint of nuttiness (similar to cashews) and are beloved by chefs for their texture and flavor. The perfect panko-fried fare, they also pair perfectly with pasta, risotto, noodle stir frys, and more. (We especially love adding them to warm creamy soups, frittatas, tacos, and even quiche!)
Our golden oyster mushroom kits are reliable producers and tend to yield large flushes of beautiful bright yellow to deep golden mushrooms when given adequate humidity. With continued proper care, you should be able to get multiple flushes. (We 100% guarantee your first flush of mushrooms, but hope you'll try for 2 or 3!)
That's not mold, it's mycelium!
Your kit includes an amended sawdust block fully colonized with mushroom mycelium. It may appear covered with a soft, white, mold-like substance - that's the mushroom mycelium! It is completely normal. The mycelium of some species is more prominent than others.

1) Inside this box is an amended sawdust block that has been completely colonized by mushroom mycelium. Open the front of your kit along the perforated line and dispose of the remaining cardboard.
2) Slice an 'X' into the plastic underneath with a sharp knife or scissors.
3) Lift open the top of your box to find the sprayer and instruction booklet. Fill the sprayer with tap water and generously spritz the plastic where you sliced your 'X' shape. Spritz your kit at least twice daily - more if you're in a particularly dry climate. (If your mushrooms start to grow but dry up and die, your growing conditions may be too dry and you should make a humidity tent!)
4) Place your kit in the most humid part of your home and outside of direct sunlight. We suggest putting it on a kitchen counter close to a sink. The mushroom mycelium will sense the oxygen in the air and produce mushroom 'pins,' another term for 'baby mushrooms.'
5) It usually takes 5-14 days for pins to form. Once pins begin to form, mushrooms will grow quickly. So when you spot your first pins keep an eye on them. The warmer the environment the faster they will grow. Mushrooms should be ready to harvest 2-5 days after pin formation.

If you're not ready to use immediately, your Golden Oyster Spray & Grow Kit can be refrigerated or stored in a cool dry place, out of direct sunlight, for up to 3 months.

The classic North Spore recipe is to chop the oyster mushrooms and sauté them in a heavy pan on medium heat with butter, garlic, and loads of fresh thyme and rosemary (or whatever other herbs you happen to have on hand!). Cook until the mushrooms have released their liquid, then continue cooking until that liquid has cooked off and the mushrooms begin to brown. This can take from 20-30 minutes. Deglaze your pan with a splash of white wine, reduce once more, and finish with a touch of heavy cream. Season generously with salt.

The spawn used in our mushroom kits is grown on USDA certified organic grain and made with organic cultures from our own culture bank. Our kits are handmade from a blend of locally sourced, all-natural, organic, and non-GMO woods and supplements from farms and forests in New England and North America.

Simply take a trash bag or other loosely fitting plastic bag and put PLENTY of 1/2 inch holes in it (THIS IS IMPORTANT: Mushrooms exhale CO2 and inhale oxygen. They will suffocate themselves if there isn’t adequate airflow! Golden oysters that look stringy or strange are usually growing that way because they need more air!). Spray the slice at least once per day with the included spray bottle. If you choose to use a humidity tent make sure to spray the inside of the tent once per day to maintain humidity.

If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.
Mushrooms grow spores as they develop. This is a natural means of reproduction. This is when people with allergies or compromised immune systems may want to consider putting fruiting mushroom kits outdoors or in a well-ventilated area. Spores in mushrooms sometimes cause respiratory irritation. In rare cases, spores may also cause irritation for some non-allergic or non-immunocompromised mushroom growers. If you are one of them, it is recommended to reduce the overall spore load by harvesting mushrooms while they are still in their younger growth stages.

Best Golden Kit Out There!
This mushroom kit surpassed my expectations. It took about 9 days to pin (because I had it in a location that was too cold at first.) Then it literally exploded with gorgeous golden mushrooms! And they cooked up like a charm. Nutty and delicious.

effortless and fun!
This was so much fun to grow! I sat the box on my kitchen counter and sprayed it twice a day and in no time had growth. It was amazing how quickly it changed and grew. Today I sautéed some of the mushrooms for breakfast and loved the taste too. All around great experience!


First flush Goldens
Easy to grow! First flush pictured here. Used the goldens in stir-fries - didn't care for the texture of the stems, so with the second flush just used the caps. Will try for a third flush.

Took a while to grow
Overall, my golden oyster mushrooms took over 4 weeks to start and pin. At first I thought it was a bad batch, and it still might be since there isn't a good size section of mushrooms growing. I purchased lions mane and black kings along with the golden oyster. The Lions mane and Black Kings truly yielded a substantial amount of mushrooms. The Black Kings were my favorite mushrooms of the 3 I grew. I guess my advice for any new grower out there, if you don't see results within the first couple weeks, be patient and monitor your growing environment. Even though the Lions Mane and Black Kings grew perfectly fine, maybe another type of mushroom needs different attention. We'll see if this Golden Oyster block might produce a second flush but the way it looks now, I'm probably shooting for a miracle. This is not a negative review at all, just a realistic view that way if someone else comes across the same experience as I, they won't get frustrated or deterred. Happy Growing.


Got off to a rocky start but then came out beautifully
A great company! I had some issues growing my mushrooms at first in the cold, dry NE winter but they helped me figure it out and even sent me a kit when my first one failed. Hint: I put a humidifier directly on it which was the trick. I tried doing the humidity tent but it didn't seem like they got enough fresh air that way. Mushrooms need to breathe! Trying oyster mushrooms for the first time was such a treat! Now I have them living a "second life" on wood chips in a laundry basket. :)
