Try it today, no chamber needed.

These run on your device with a store-bought grow bag. Nothing is sent anywhere and no account is needed.

Plan a grow

Three answers about your room, your goal and your refill give one species that fits, and say plainly when it needs a cooler spot.

Room check

Put your room's temperature and humidity against the colonization and fruiting windows.

Grow tracker

Log a species and a start day. It shows the day count, the phase and the next step. Kept in your browser only.

What it is designed to do

Warm, humid and quiet.
Not a refrigerator.

Growing mushrooms is mostly a temperature and humidity problem: warm to colonize, cooler to fruit for many species. The Sh-Room is a working prototype built to take care of the warm, humid part quietly on a kitchen counter. It uses a standard grow bag, and it is repairable by design, with no sealed pods.

Holds the conditions

The prototype warms the bag, keeps the air humid and moves it gently while the mycelium claims the block. That covers the colonization weeks of a grow.

Quiet by design

Design target: under 18 dB

The goal is a chamber you forget is running. Under 18 dB is the target we are building toward; we have not published a measured figure for a production unit, and we will say so when we have one.

The grow science →

Heat only, honestly

It warms; it does not refrigerate. Cool-fruiting species such as shiitake, maitake and blue oyster want 55 to 65°F, below a warm kitchen. The plan tool tells you which species suit your room as it is.

Plan your first grow →

A prototype, not a product in production. A version that also cools is an idea, not built. We would rather name what each thing does than show you a spec it cannot hit.

We grow food. We also cover the whole fungal kingdom — honestly.

Essays about growing mushrooms at home: species notes, harvest stories, the science at the edges of what fungi can do, and what tending something alive on its own schedule teaches you.

When the Data Comes Home

The largest real-world study of legal psilocybin came from our own backyard — CU Anschutz, 2,363 sessions in Colorado and Oregon. Depression and anxiety scores roughly halved at two weeks, and more milligrams didn't buy more benefit. Here's the honest read, small print and all — including the suicidality signal no summary gets to skip.

The Mushroom Left the Mushroom

Bioengineers just brewed psilocybin in bacteria — grams per liter, no fruiting body at all. What it means that a molecule fungi spent 100 million years perfecting now pours out of a fermenter, and what's gained and lost when the mushroom leaves the mushroom.

The Chamber Is Quiet. Your Phone Keeps the Log.

Why the chamber is dumb on purpose, why your grow log stays on your device, and what a daily coach could say if it is ever built.

The Sh-Room Ecosystem.

A mushroom isn't a solo organism. It's a network. This is the community we want to build around the Sh-Room. None of it is running yet; the unit is still a prototype.

Harvest Circle

Share the unit, not the cost

Planned: grow a cycle, sanitize, pass the unit to a neighbor, with a maintenance log, a clean-cycle protocol and a handoff checklist. Not running yet.

Spore Library

Community culture bank

Planned: a neighborhood library of gourmet cultures such as blue oyster, lion's mane and shiitake. Borrow one, grow it, return a culture from your healthiest flush. Not running yet.

Local Chapters

City by city, block by block

Planned to start in Boulder, CO: local groups that run their own Harvest Circles, culture library and monthly grow meetups. No chapters exist yet.

Grow Journals

Photos, data, and stories

Planned: share photos and notes from each grow and compare colonization speeds across species.

Harvest Exchange

Gift fresh, never sell

Planned: a place to gift surplus harvests to neighbors, labelled with species, harvest date and storage notes. Gifting only; no money changes hands. Not built yet.

Species Database

Community growing guides

Today: our own grow profiles on the Strains page (temperature, humidity, days to fruit, flavor). Planned: add growers' results once there are growers.

Tool Library Partners

Check out a Sh-Room like a book

Planned: ask tool libraries and makerspaces to lend Sh-Room units for a 30-day grow cycle. No library partnerships exist yet.

Impact Dashboard

Track what we grow together

Planned: a shared tally of food grown at home and packaging avoided, built from harvests growers choose to log. Not built yet.

The Mission

Rid the world of single use.

Single-use bottles. Single-use kits that end up in the trash after one cycle. Single-use products designed to be replaced. The Sh-Room is designed to be reused: the substrate refills, and the liner is designed to wash 50+ times. One unit, many grows.

Join the waitlist. We'll write when the Kickstarter launches.

From concept to reality

We got tired of noisy,
single-use grow kits.

Every home mushroom kit we tried made the same three compromises: it hummed like an appliance, it fell apart after a grow or two, and it cost more than the mushrooms it produced. So we built the one we wanted — quiet enough to forget it's there, made of parts you can replace yourself, and cheap to run for years.

Sh-Room is a small team, not a factory with a logo. We're not trying to sell you a subscription or a proprietary pod. We're trying to put a living thing on your counter and get out of the way.

Designed where we grow

Not a drop-ship relabel from a registered-agent address. Sh-Room is designed and engineered in Boulder, on the counters we actually use.

See how it works →

Repairable with a screwdriver

The design goal is standard, replaceable parts and a screwdriver, with no sealed pods. Nothing to send back, nothing to landfill. A goal for the prototype, not a production spec.

What it does →

The goal is a chamber that disappears into the room; most home kits sound like a mini fridge. A target for the prototype, not yet a measured production figure.

The grow science →

Mostly recycled and upcycled materials, a washable liner, and a planned Harvest Circle so one unit could serve a neighborhood. A target for the prototype.

How we're building this

Radically honest, including about the AI.

This entire website was designed and built by AI, working with our team. We think that's worth saying out loud rather than hiding — it's how a small team ships something this considered. Where you see a rendered concept image, it's labeled as one; the physical Sh-Room is a real prototype, and every backer update will carry real photos and real manufacturing progress, not renders dressed up as product shots.

The deal is simple: we tell you what's finished, what's in progress, and what could go wrong — before you back it, and every week after.

Before you back anything

The internet is full of near-identical “smart” gadget campaigns. Here’s how to tell us apart.

You should be skeptical of any first-time Kickstarter. So instead of asking you to trust us, here’s exactly how we’re built differently — each one you can go check yourself.

A faceless “product design team,” new account, no track record.

Designed in Boulder by a small team that got tired of noisy, single-use kits.

Proprietary pods you can only refill from them.

The design goal is standard, replaceable parts and a screwdriver, with no pods to be locked into.

See the proof →

Shipping “confirmed after the campaign,” refunds refused.

Our plan: flat shipping shown before anyone pledges, and refunds up to 30 days before ship.

Renders dressed as product photos, specs that shift in the comments.

Renders labeled as renders, design targets labeled as targets, real prototype photos as we go.

And honestly — don’t back us if:

You just want cheap mushrooms. Buy them at the store — growing costs about the same. You do this for freshness and species you can’t buy, not to save money.
You want zero attention. The Sh-Room is built to hold conditions, but a grow still wants you to look at it and harvest on time. That’s the point of it.
You need to refrigerate a warm room today. The prototype heats; a version that also cools is an idea, not built. Check what fits your kitchen.

If none of that scared you off, you’re exactly who we built it for.
