A Pink Oyster cluster on your counter by Tuesday, or a bag of Lion's Mane spawn and a long weekend of tinkering. That is the real split between these two brands. Here is how to decide between them.
You searched for a mushroom kit and ended up on two tabs
Both brands are real. Both ship. Both have customers who swear by them. The reason you ended up comparing is that they solve the same job in two completely different ways.
North Spore is a Portland, Maine company. Their catalog is wide: dozens of species as spawn, sealed sawdust blocks, liquid culture, agar, foraging books, cordyceps powder on grocery shelves. They are a mushroom supply house that happens to also sell beginner kits.
Lykyn is a hardware company. We make one physical thing: the Smart Mushroom Grow Box. It is a countertop chamber with a sealed humidity loop, air exchange on a timer, and a phone dashboard. We also sell four species as pre-colonized blocks that slide into the chamber. That is the whole lineup.
If you want a mushroom supply house, North Spore is the answer. If you want the growing to run itself, Lykyn is the answer. Most of the rest of this piece is how to tell which one you actually want.
What North Spore does best
They are strong in three places and we will say so plainly.
Catalog breadth. If the species you want is King Trumpet, Blue Oyster, Nameko, Chestnut, Reishi on a log, or Cordyceps on rice, they probably stock it. We stock Lion's Mane, Shiitake, Pink Oyster, and Pioppino. That is it. For a cultivator who likes to rotate species every month, their catalog wins on reach.
Foraging and education. North Spore co-founder Jon Carver has a book on wild mushroom identification. Their blog has long entries on bolete walks and the deep foraging culture of the US Northeast. Their newsletter reads like a nature magazine. We do not match that. We write about the chamber and the four species inside it.
US retail footprint. You can find North Spore kits in Whole Foods, independent garden centers, and a growing list of specialty grocery stores. If you want to touch the box before you buy, they are easier to find on a shelf. Lykyn is online only.

What Lykyn does best
We solve one problem well: taking the manual labor and the guesswork out of the fruiting stage.
Automation. A North Spore grow bag asks you to cut an X in the plastic, mist two to four times a day, and watch for pins. Miss a day in week two and the caps crack. Our chamber keeps the inside at 85 to 95 percent relative humidity on its own. The air exchange runs on a schedule. You check the phone when you want to.
Countertop form factor. The chamber is roughly the footprint of a stand mixer. It lives next to the kettle. Our top-selling variant is Bone White, 42 centimeters tall, with a sliding glass door. North Spore kits sit on top of their shipping cardboard, under a transparent plastic tent that you build yourself. That tent is honest, cheap, and effective. It is also not something most people want on the counter for three weeks.
In-house R&D. The PCB, the firmware, the mobile app, and the sensor stack are built by five engineers in Kocaeli, Turkey, with the device certification work running out of TUBITAK MAM. We own the moulds. When a sensor misreads, we fix it on the next firmware push and OTA update the fleet. That is a hardware company answer.
EU presence. We ship from the EU for European customers and from the US for US customers. North Spore does not ship fresh spawn outside North America for cold-chain reasons. If you are reading this from Berlin or Lisbon, that matters.
Honest side-by-side
| Question | North Spore | Lykyn |
|---|---|---|
| Form factor | Sealed grow bag plus a plastic humidity tent you set up | Countertop chamber, sliding glass door, phone app |
| Daily effort | Mist by hand, 2 to 4 times a day | Open the app, water reservoir top-up weekly |
| Species range | Dozens: spawn, blocks, liquid culture, agar | Four: Lion's Mane, Shiitake, Pink Oyster, Pioppino |
| Reusable? | Bag is single-use; tent you keep | Chamber is the product; blocks are the refills |
| EU shipping | North America only for live spawn | Yes, from EU warehouse |
| Who it fits | The curious cultivator who wants to try everything | The home cook who wants fresh culinary mushrooms with no fuss |
Neither row is a knock on the other brand. We ship both styles of product in our own warehouse and ran a North Spore Lion's Mane bag on the shelf next to a Lykyn chamber for six weeks before writing this. In August 2026 we logged a flush where the shiitake caps browned faster than we expected after a 24-hour FAE pause: that same timeline would have been a dead bag in a plastic tent, because missed days compound. The chamber held it, we got the pins back, and the lesson was that automation forgives the owner more than a manual rig does.
When to pick which
Three short rubrics to short-circuit the comparison.
Pick North Spore if: you want to try six species in a year, you like the ritual of misting, you live in the US, and the plastic tent on the counter does not bother you. If you are already deep in cultivation and want spawn, agar, or liquid culture, they are your supplier.
Pick Lykyn if: you want fresh mushrooms the way you want fresh herbs: on the counter, running on their own, visible through glass, with a phone that tells you when something is off. The chamber is a one-time purchase. The blocks are the refills.
Pick both if: you are a mushroom-curious cook with time on weekends. Run a North Spore spawn project in the garage for the species we do not carry (King Trumpet, say) and keep a Lykyn block cycling on the kitchen counter for weeknight dinners. We know growers who do exactly that.
The chamber, if that is the lane you want
If you only want to try one species
Grocery stores carry button mushrooms and sometimes a tray of brown shiitake. They almost never carry Lion's Mane, Pink Oyster, or fresh Pioppino. That is the real reason to grow at home: access to species the shelf does not carry.
Two blocks slot into the chamber and give you a first flush that fills the glass. Both ship from our warehouse already colonized, so you are not starting from spawn.
Frequently asked questions
Is North Spore a legitimate company?
Fully legitimate, and good at what they do. Portland, Maine, founded 2016, large catalog of spawn and grow kits, well regarded in the US hobbyist and small-farm cultivation community. Nothing we write here is a knock on their operation.
Does Lykyn sell grow bags like North Spore does?
Only the four species that fit the chamber: Lion's Mane, Shiitake, Pink Oyster, Pioppino. We do not sell spawn, liquid culture, or agar. For those, go to a supply house like North Spore.
Can I use a North Spore grow bag inside a Lykyn chamber?
Most of the time, yes, with one caveat. If the block fits (around 5 lb, standard filter-patch bag), the chamber will hold the humidity and air exchange for it. The one honest watch-out is species mismatch: if the species they ship wants cold shock or very low RH for pinning, you will need to adjust the chamber profile. Our four species presets are tuned to the four blocks we ship.
Does the chamber ship to the EU?
From an EU warehouse, yes. Pre-colonized blocks ship fresh with cold packs where the route is longer than three days. North Spore ships their live spawn only inside North America for cold-chain reasons.
Which one gets me mushrooms faster?
Roughly tied to the first fresh harvest. A North Spore bag pins in seven to fourteen days once you cut the X. A Lykyn block pins in a similar window once the chamber ramps. The real time difference is the second and third flush, where the chamber holds environment steady and the bag starts to dry out.
Can beginners handle the Lykyn chamber?
Our intent is yes. The app walks you through the three decisions a new grower would otherwise google: when to open the door, when to top up water, when the block is spent. If you have never grown a mushroom before, the chamber is friendlier than a bag and a sprayer.
Where can I compare prices directly?
Catalogue and price lists live on each company's own site. Our chamber plus blocks live on this store. For North Spore's current lineup and pricing, visit northspore.com. We will not quote their numbers second-hand because they change them and we would rather not misrepresent the brand.
