Our beginner-friendly, USDA-certified organic oyster mushroom countertop kits make growing your own mushrooms so easy. Just open the front of the box, cut an “X” into the plastic bag, spray with water 2-3 times a day, and watch them grow!
Why we love them:
Blue oyster mushrooms are velvety, savory, and mild and pair perfectly with just about any recipe! Blue oysters are a staple here at North Spore (going all the way back to when we began as an urban farm.) After perfecting our blue oyster kits over the years, they’ve become one of the easiest kits to get multiple fruitings from and should produce a second flush of mushrooms (or more!)
About the kit:
Our blue oyster mushroom kits are reliable producers and tend to yield large flushes of beautiful light grayish-brown to deep blue-gray mushrooms when given adequate humidity. With continued proper care, you should be able to get multiple flushes. (We 100% guarantee your first flush of mushrooms, but hope you'll try for 2 or 3!)
That's not mold, it's mycelium!
Your kit includes an amended sawdust block fully colonized with mushroom mycelium. It may appear covered with a soft, white, mold-like substance - that's the mushroom mycelium! It is completely normal. The mycelium of some species is more prominent than others.

1) Inside this box is an amended sawdust block that has been completely colonized by mushroom mycelium. Open the front of your kit along the perforated line and dispose of the remaining cardboard.
2) Slice an 'X' into the plastic underneath with a sharp knife or scissors.
3) Lift open the top of your box to find the sprayer and instruction booklet. Fill the sprayer with tap water and generously spritz the plastic where you sliced your 'X' shape. Spritz your kit at least twice daily - more if you're in a particularly dry climate. (If your mushrooms start to grow but dry up and die, your growing conditions may be too dry and you should make a humidity tent!)
4) Place your kit in the most humid part of your home and outside of direct sunlight. We suggest putting it on a kitchen counter close to a sink. The mushroom mycelium will sense the oxygen in the air and produce mushroom 'pins,' another term for 'baby mushrooms.'
5) It usually takes 5-14 days for pins to form. Once pins begin to form, mushrooms will grow quickly. So when you spot your first pins keep an eye on them. The warmer the environment the faster they will grow. Mushrooms should be ready to harvest 2-5 days after pin formation.

If you're not ready to use immediately, your Blue Oyster Spray & Grow Kit can be refrigerated or stored in a cool dry place, out of direct sunlight, for up to 6 months.

The classic North Spore recipe is to chop the blue oyster mushrooms and sauté them in a heavy pan on medium heat with butter, garlic, and loads of fresh thyme and rosemary (or whatever other herbs you happen to have on hand!). Cook until the mushrooms have released their liquid, then continue cooking until that liquid has cooked off and the mushrooms begin to brown. This can take from 20-30 minutes. Deglaze your pan with a splash of white wine, reduce once more, and finish with a touch of heavy cream. Season generously with salt.

Simply take a trash bag or other loosely fitting plastic bag and put PLENTY of 1/2 inch holes in it (THIS IS IMPORTANT: Mushrooms exhale CO2 and inhale oxygen. They will suffocate themselves if there isn’t adequate airflow! Blue oysters that look stringy or strange are usually growing that way because they need more air!). Spray the slice at least once per day with the included spray bottle. If you choose to use a humidity tent make sure to spray the inside of the tent once per day to maintain humidity.

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.
Mushrooms grow spores as they develop. This is a natural means of reproduction. This is when people with allergies or compromised immune systems may want to consider putting fruiting mushroom kits outdoors or in a well-ventilated area. Spores in mushrooms sometimes cause respiratory irritation. In rare cases, spores may also cause irritation for some non-allergic or non-immunocompromised mushroom growers. If you are one of them, it is recommended to reduce the overall spore load by harvesting mushrooms while they are still in their younger growth stages.

I never want store bought again
This was one of the most easy things I've ever grown. It is exciting to see how fast they grow. You will become hooked and getting a full boomer bin before you know it.

Congrats on your awesome flush! Welcome to the mycology club!
Effortless explosion of mushrooms!
This kit was my introduction to growing mushrooms. Simple to set up and three weeks later I woke up to an overflowing box on my kitchen counter! Couldn't have been easier. Tonight is harvest time. I'm already hoping for another flush. The tiny sprayer in my kit was damaged, but a regular spray bottle worked just fine.

Thank you so much for the review, and congrats on your gorgeous flush!
Worth the effort
This kit gave me some trouble at first and showed no signs of life for nearly 3 weeks. Thanks to some input and feedback from North Spore, (we moved this to our basement as Blue Oyster likes it a little cooler) we just harvested our first flush this morning and are planning on breading it and frying it up nice and crispy.

Awesome, Nick! Thanks for sharing. Our team is here to help if you ever need anything.
Blue Oyster Cult
My brother was very happy receiving. He is excited to spray and watch the mushrooms grow. I surprised him after sharing with him that I purchased a Blue Oyster mushroom kit for someone else. He responded " Blue Oyster Cult"
The Kit That Got Me Into Mycology
The spray and grow kit from North Spore is what got me into mycology several years ago. Simple to use, beyond fun to grow, and incredibly rewarding to harvest and enjoy. 10/10 would recommend to friends and family.

Thank you so much for spreading the spore, Colin!
