"The quality of my Blue Oyster kit and the customer service from North Spore is unbeatable. It was my first time experimenting with growing mushrooms and this was a simple and amazing way to start. Now I am hooked!"
"North Spore's spray and grow kits are awesome. I harvested more than a 1/2 lb of mushrooms less than 2 weeks after I opened the box and I already have a second flush going! This was so much fun. I would definitely recommend."

From 'pin' to 'flush' - harvest your kit in about 2 weeks
On average, it takes about 4-9 days for your kit to begin “pinning.” From there, your baby mushrooms should grow rapidly if proper humidity and temperature are maintained. When you have a full flush, it's time to harvest!
Give your kit back to the earth and grow more mushrooms
When your kit no longer produces any flushes indoors, you can still use it to grow mushrooms! Watch this video to learn more about planting your grow kit in the garden.
Frequently asked questions
How long does a mushroom grow kit take?
Once you've activated your mushroom grow kit, it will take approximately 1-2 weeks to start seeing mushroom 'pins' (which are baby mushrooms!) Once you see pins, it takes another 3-5 days before your mushrooms are fully grown and ready to harvest!
How many flushes can a mushroom grow kit produce?
The average mushroom growing kit produces 2 flushes, but some can produce up to four! When your grow kit has finished producing indoors, you may be able to get more life out of it outside!
Are North Spore mushroom growing kits beginner friendly?
Our mushroom growing kits are specifically designed for beginners! They are super easy to use, take no prior experience, and need no other equipment. Their small size means they fit into most spaces. (Just make sure they have adequate air flow and humidity.)
What is the shelf life of a mushroom grow kit?
Our mushroom grow kits can last up to several months if stored in a cool, dry place away from direct sunlight. But, because mycelium is a living organism, we suggest you activate your kit as soon as possible. Otherwise it might start growing on its own, right through the box!
How often should I water my mushroom grow kit?
We recommend giving your mushroom kit a few spritzes a few times per day, but if you live in a very dry climate you may want to spray it more often.
Can I use a mushroom grow kit any time of year?
Yes! Our mushroom growing kits allow you to grow mushrooms indoors all year-round. (Depending on where you live, you may need to provide a little more humidity or warmth for pink and golden oysters in the winter.)
How many mushrooms will one grow kit produce?
A mushroom grow kit typically produce 2-3 flushes ranging from .5lb to 1.5lbs each.
When should I harvest my mushroom grow kit?
With oyster mushrooms, we recommend harvesting before caps become brown and concave. With lion's mane mushrooms, we recommend harvesting when it forms a large pom pom or visible teeth -- and before it dries out. (See photos on the product pages for reference.)
How do I harvest my mushrooms?
Gently hold your flush and twist from the base, careful not to rip off much of the block itself.
Should I eat my mushrooms raw or cooked?
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. Uncooked mushroom fruit bodies contain high amounts of chiton which is difficult to digest until cooked.
Is there a 'best way' to cook my mushrooms?
Frying your mushrooms with butter or oil, and a dash of salt and pepper is the easiest way to cook them! Be sure to cook them until crispy, otherwise they'll be chewy. Also, with lion's mane, be sure to press out excess moisture beforehand for best results.
What do mushrooms taste like?
Oyster mushrooms are earthy and meaty. Lion's mane mushrooms have the flavor and texture of crab. (Many folks even like to make vegan lion's mane "crab cakes" as a comparable meat-free alternative!)
What should I do with my mushroom grow kit once it's finished?
Once you have gotten 2-3 flushes of mushrooms from your kit, there are a few things you can do with it to give it more life! Check out the video below for ideas.
