Instructions
Instructions
- Slice an 'X' into the plastic underneath with a sharp knife.
- 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.) - 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.
- 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
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.
- 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.
- 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.
Storage
Storage
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.
Our Guarantee to You
Our Guarantee to You
We 100% guarantee your fruiting block with grow mushrooms or we 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.

This is my second time ordering from Mushroom grow Kit co. We probably should have cut open the lions mane and pink oysters already but there are only so many mushrooms you can eat in a week. Super happy :)
A repeat purchase from a customer is the best compliment we can receive. Thank you Tom! Let us know when you need more mushroom growing blocks. You can always refrigerate the lion's mane block to prevent in from fruiting in the bag. With pink oyster mushrooms we would suggest using that block first since it can't be refrigerated unlike the blue oyster mushroom blocks.
I got over a pound off the first harvest of blue oysters and then had to make a humidity tent to provoke the 2nd flush. The 1st flush of lion’s mane mushrooms look gorgeous so far.
Arrived quickly and all three blocks produced a ton of mushrooms. I can't believe how big the first flush of lion's mane was.
Thank you Matt! Happy to hear our fruiting blocks are working out for your home grow :)

My go to for lions mane fruiting blocks anytime I need fresh lions mane

These pink oysters are super vibrant when they first pop out.

This is my second time ordering from Mushroom grow Kit co. We probably should have cut open the lions mane and pink oysters already but there are only so many mushrooms you can eat in a week. Super happy :)

I threw these lion's mane fruiting blocks in our little grow tent in the garage. They are amazing! I still can't believe how many mushrooms they have produced. Great quality and fast shipping.

These blue oysters look amazing! I haven't even harvested them yet but the first flush is huge so far. I've tried other mushroom grow kit brands and haven't had much luck with them. I can't wait to eat these and will definitely be ordering more soon. Thank you Mushroom Grow Kit Co!!

Arrived quickly and all three blocks produced a ton of mushrooms. I can't believe how big the first flush of lion's mane was.
