Discover everything Mushroom Grow Kit Co. has to offer in one place. Featuring premium oyster mushroom growing kits and lion's mane grow kits. Ideal for beginners and experienced growers, our edible mushroom kits include everything you need to easily cultivate your own bountiful harvests at home.

All of our mushroom grow kits and fruiting blocks are made with an organic master's mix substrate base and first-generation grain spawn. This is why our mushroom kits work so well for home growers.  

Grow Mushrooms Indoors and Outdoors

Elevate your indoor gardening experience with our Spray and Grow Mushroom Kits. They are the best mushroom growing kits for beginners and very easy to use. 

Are you a more experienced grower? Our fruiting block mushroom grow kits are perfect for throwing in your automated grow tent or to use outside in your garden.

Plant them in your garden bed, a bucket, or pot like you would a basil or tomato plant (or crumble up the block and mix it in with your garden soil and wood chips). Packed with nutrients and delicious flavor, these gourmet mushroom kits will thrive in your home garden.

You can also use a mushroom fruiting block as a spray and grow kit.

The Mushroom Grow Kit Co. Difference

We take pride in both the quality of our mushroom kits and our customer service. 

At Mushroom Grow Kit Co., we use organic master's mix for our substrate (50% hardwood oak and 50% soy hulls). Master's mix is known as a fast-fruiting substrate because it is densely packed with so many nutrients. This gives you the best yield and largest amount of mushrooms per grow kit.

When we switched from supplemented hardwood sawdust substrate to master's mix, our 5 lbs grow kits went from producing 1-2 lbs per grow kit to 2-3 lbs per grow kit. 

We use first-generation grain spawn for all of our mushroom kits, which means they are stronger and younger.

Since we autoclave and fully sterilize every mycelium block, our mushroom grow kits come completely hydrated and healthy. 

"Huge Yields and Delicious Results. I purchased both the oyster mushroom grow kits and the lion's mane mushroom grow kit. They all produced amazingly well. The setup took less than 5 minutes. Just mist with water and they do the rest. What really impressed me was the yield. I got more mushrooms from this mushroom grow kit than I did from previous kits I’ve tried from other brands. These grew restaurant-quality clusters. If you want a reliable at home mushroom grow kit that produces consistently, this is the one to get!"

-Blake Parrish, 5-star review, 3 Pack - Lion's Mane, Pink, and Blue Oyster Mushroom Growing Kit

"Farmers market blocks. We have a microgreens booth at the farmers market and got these grow kits with an AC Infinity tent setup. Customer service set us up with a wholesale pricing for bulk fruiting blocks. Very happy so far."

-Eden, 5-star review, 4 Pack - Lion's Mane, Gold, Pink, and Blue Oyster Mushroom Grow Kit Fruiting Blocks

"Much better than North Spore. Bigger, better mushrooms. There was no need to rehydrate the mushroom mycelium as it was only 3 weeks old. We got over 2.5 pounds of fresh lion's mane on the first harvest. North spore's grow kits are smaller and a few months old. You can definitely tell a difference in quality. Thanks Mushroom Grow Kit Co!"

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.

You can also make your own out of a plastic bag or clear plastic bin.

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?

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

Mushroom mycelium makes a nutrient dense, healthy soil for your plants and food. Depending on the climate, you may get additional flushes of mushrooms popping up in your garden.

What is the difference between a fruiting block and boxed mushroom grow kit?

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.

Who makes Mushroom Grow Kit Co.'s grow kits?

All of our mushroom grow kits and fruiting blocks are hand made by Phoenix Mushroom Farm, our family farm in Phoenix, Arizona.
