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. 

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

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.

Frequently Asked Questions

How long does it take to grow mushrooms?

Most oyster mushroom grow kits have the first harvest (or “flush” in mushroom terms) ready in 7-10 days of starting your grow kit.

Lion’s Mane can take a little longer and is usually ready to harvest in 2-3 weeks of starting your grow kit.

Did you know you can 3-4 flushes (harvests) of mushrooms per grow kit?

Each round of fresh mushrooms is smaller than the previous but keep spraying your kits to get as much as you can out of them.

Do I need a humidity tent?

No...unless you want bigger, fresher mushrooms.

Our grow kits are made to be used without a humidity tent, but having 100% humidity creates a growing environment for mushrooms to flourish.

Our flexible humidity tents have ventilation holes for fresh air exchange (mushrooms breath oxygen just like we do) and are easy to store when not in use.

They also help protect and keep clean your grow kit, table top, kitchen counter, or shelf.

Is it safe to grow mushrooms in my house?

Yes. If you are worried about mushroom spores in your house don't be! Mushrooms should be harvested or picked before they spore. If you don't catch them in time, they produce a miniscule amount you can easily wipe up.

If you have mushrooms growing out of the walls of your house, you need to clean your house more often (respectfully😅).

A humidity tent also helps contain any unwanted spores.

How many rounds of fresh mushrooms will my grow kit produce?

We 100% guarantee your 1st flush (harvest) of mushrooms.

Your grow kit can easily produce a 2nd and 3rd round of fresh mushrooms (even a 4th if you push it).

Just keep in mind that every new flush of mushrooms is subsequently smaller than the previous.

We recommend getting a new grow kit after your second harvest if you are trying to grow mushrooms as a consistent food source to cook with.

When done, crumble up your mycelium block and use it as garden soil or compost!

Do I need special equipment to grow?

No, not at all. Our beginner-friendly mushroom grow kits come with a free spray bottle included and are made to be used upon arrival with no additional equipment needed.

Mushrooms are low maintenance. All they need is a few sprays of water 2-3 times a day and some love.

Can I grow mushrooms year-round indoors?

Yes! Our mushrooms grow kits are made to be used indoors. This stable environment allows you to grow them anytime, anywhere inside.

Does you home temperature fluctuate?

So does the temperature outside where mushrooms naturally grow.

Lion's mane and oyster mushrooms can tolerate a range of temperatures from 60-85 degrees.

What do I do with the grow kit once it is done?
