Why we love them:
Lion's mane mushroom kits are the easiest of all our Spray & Grow Kits and produce plump, dense, shaggy mushroom clusters. Lion’s mane is highly versatile and can be enjoyed cooked, dried, extracted, or even steeped as a tea! And because it contains brain-supporting compounds, it’s also a popular medicinal mushroom in addition to a delicious fungi fan favorite. (Meatless crab cakes, anyone?)
Our lion's mane mushroom kits are reliable producers and tend to yield large flushes of beautiful creamy white mushrooms when given adequate humidity. With continued proper care, you may be able to get multiple flushes. (We 100% guarantee your first flush of mushrooms, but hope you'll try for 2 or 3!)
Note: Lion's mane can be prone to drying out if the ambient humidity is too low, so we recommend that you water it generously.
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 Lion's Mane Spray & Grow Kit can be refrigerated or stored in a cool dry place, out of direct sunlight, for up to 3 months.

Due to its consistency and flavor, lion's mane can be used as a seafood substitute in recipes. We like to slice it into rounds and pan-fry it in olive oil or butter, or try ripping it up and making 'Lion's Mane Cakes' by following a crab cake recipe with the lion's mane subbing in for the crab meat.
-
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! Lion's mane 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.

easy to grow
Lion's Mane, my first grow kit. Easy to grow, now ready to harvest. Cooked up a small amount in butter with a little salt and pepper. Great flavor and consistency!

Amazing product and a great gift!
I ordered the lion's mane spray and grow kit for my wife's birthday and it was the perfect gift. Super easy to grow and harvest the mushrooms and we even recycled the substrate to keep the fun going. We made krab cakes out of the fruiting body and they were delicious. I would recommend this to anyone who's curious about mushroom cultivation....and I have!

Fun and tasty
So easy to grow and delicious, too! Our kit produced two flushes and may have made more if we'd taken better care of it.

AMAZING gifts!!!
I purchased many Spray & Grow kits to send out for gifts. It was so much fun to introduce everyone to the thrill of growing these amazing mushrooms! This was definitely a hit with ALL that received them and I highly recommend these! In addition, the customer service is wonderful.


Didn't have luck at first and now they are one their fourth round!
There was nothing wrong with the kit but I had some initial trouble with my first flushes due to it being the middle of winter in the NE. Even with a humidity tent and trying a few places around the house they just weren't doing well (I learned later using a humidifier next to the kit really helps). I watched some of North Spore's videos about keeping your box going and decided to try crumbling up the mycelium in some aspen wood chips (I just used pet bedding) in a laundry basket in my basement, covering it with a garbage bag, and forgot about it for a month or so. I was not convinced it would really work. I'm glad I decided to check on it today because I found it covered in new mushrooms! Honestly it was the most incredible surprise and I'm now forever obsessed with fungi + North Spore.
