Lion's Mane Mushroom Growing Kit - 5 LBS Spray and Grow

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.

The best mushroom grow kits for beginners to start with are Spray and Grow tabletop kits. We recommend starting with lion's mane grow kits blue oyster mushroom kits.

Lion's mane mushroom grow kits will take a little longer but are very easy and low maintenance for first time growers.

Blue oyster mushroom grow kits are aggressive growers and ready in 7-10 days.

We recommend using your lion's mane mushroom grow kit upon arrival or as soon as possible for best results. If you would like to wait, you can store your mushroom kit for up to 6 months in the refrigerator or a dry, cool, dark space inside. Remember, your lion's mane grow kit is a living organism.

Fresh lion's mane mushrooms are normally ready to harvest 2-3 weeks after starting your spray and grow kit.

Other signs your lion's mane grow kit is ready to harvest:

• The spikes or teeth of the lion's mane mushrooms start elongating
• The lion's mane mushrooms turn yellow, brown, or start drying out.

You should spray your mushroom kit at least twice a day. If you can spray it four to five times a day, your grow kit will be much happier.

If your block appears dry, you should add more water. We recommend 8-10 sprays each time.

A humidity tent will help keep up the humidity level in between sprays and is helpful to us.

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. Your first harvest should be 2 to 2.5 pounds of fresh mushrooms.

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!

Mushroom Grow Kit Co. is consistently the best value for your money when you look at quality, price per pound of fresh mushrooms grown, and reliability.

Our mushroom grow kits perform better than North Spore's for a few different reasons.

At Mushroom Grow Kit Co., we use first-generation grain spawn for all of our grow kits (which means it is stronger and younger). We also use organic master's mix for our substrate. Master's mix consistently grows the most mushrooms because of how nutrient-packed the organic hardwood oak and soy hulls are when combined with our grain spawn. This is why our grow kits actually work so well for home growers.

High-quality substrate and grain spawn makes high-quality mycelium, which in turn grows high-quality mushrooms.

We autoclave and fully sterilize every mycelium block so our mushroom grow kits come completely hydrated and healthy.

Other mushroom grow kit brands like North Spore and Back to the Roots use supplemented sawdust for their substrate. Using only sawdust cuts the yield in half compared to master's mix. It also tends to lead to drier, less hydrated blocks, especially if the blocks are steam pasteurized and not sterilized in a proper autoclave.

Our customer service team is made up of actual mushrooms farmers who grow mushrooms on the daily for a living. We are willing to go the extra mile with personalized grow tips to make sure your grow kit is a success.

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.

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.

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.

A fruiting block is a mushroom grow kit that comes in bag, not a box. They also do not include a free spray bottle. Otherwise the fully colonized block of mycelium is the same heart and soul of our boxed grow kits.

This allows us to keep our prices low (without compromising on quality) and pass on the savings to you, our beloved customers.

Fruiting block grow kits are a better choice for those who want to grow mushrooms in a martha tent set up, grow tents, or anything with an automated humidifier running.

Our mushroom fruiting blocks are also perfect for your BoomRoom from North Spore if you have one.
