Jardin · the grow system · in development

Set it. Check in. Tell it what you see. It adjusts.

A near-autonomous high-pressure aeroponics system with deep water culture support, built from small controller nodes and a local hub, around hardware already on the bench: pH and EC probes, temperature and humidity sensors, peristaltic dosers, pumps, solenoids, flow meters and load cells.

The mix station · one batch, many tents

Fresh water in. The right feed out to every tent.

For bigger rooms the mixing moves out of the tent. One station fills, doses, stirs and checks a batch, then a manifold sends it to each tent on its own valve, and runoff goes to waste. Watch one cycle run.

FillFresh water in, counted by the flow meter and the scale.
DoseStock jugs dose one at a time, calcium first, each checked in grams.
MixCirculate so nothing meets at stock strength.
SettleLet the probes settle before anything is trusted.
VerifyEC must match the prediction, pH in band, weight adds up. Or it stops.
DeliverThe manifold opens one tent at a time, each on its own recipe.
Drain and flushRunoff goes to waste, lines get a plain-water flush.

The system · how it fits

The hub plans. The nodes execute.

Misting never depends on the hub, the Wi-Fi or the cloud. If the hub dies, the Root node keeps misting on its last 24-hour plan, on battery if it has to.

Every way you grow · 14 systems, one Root

Aeroponics, water, coco or dirt. Same brain.

One controller, one app, one journal. Switch the root mode between grows, plug in the matching sensors, and Jardin picks up the right ones on its own.

14 systems

Flood and drain

Floods a table to the standpipe on a schedule, drains back by gravity.

Root zone: Inert media on a table

Automation: Level 3

Drip, recirculating

Measured shots through emitters; runoff returns and is watched for EC drift.

Root zone: Coco, rockwool, clay
If a pump dies: 12–36 h
Automation: Level 3

Drip to waste + crop steering

Dryback-driven P1/P2/P3 shots from substrate VWC and EC; fresh batch every few days.

Root zone: Coco, rockwool
If a pump dies: 12–36 h
Automation: Level 2 → 3 after 10 steered grows

Soak, bottom-water, wick

Fills the tray to a level, dwells, drains or holds. Gentle and soil-friendly.

Root zone: Pots in a tray
If a pump dies: Days
Automation: Level 3

Coco

Hydro-like and fast-drying; buffer check in week one, then dryback steering.

Root zone: Any irrigation
If a pump dies: 12–36 h
Automation: Level 3

Rockwool

Inert and unbuffered; slab EC is the lever, so a VWC/EC probe is strongly recommended.

Root zone: Any irrigation
If a pump dies: 24–48 h
Automation: Level 3

Soil, bottled feed

Moisture-led watering with long dry-downs and dilute feed. Dosing caps halve.

Root zone: Buffered, biological

Root zone: No-till, microbial
If a pump dies: Days
Automation: Level 3 (water only)

"If a pump dies" is how long roots survive when the irrigation actuator fails at lights-on in a warm room; rough field estimates we'll check on the bench. Automation levels: 0 monitor, 1 suggest, 2 act with approval, 3 act within recipe bounds.

Plug in and go

Labelled locking ports on the node. Plug a sensor in and Jardin identifies it by its address or an ID resistor in the cable, then shows it in the app.

Jardin Dose · four tiers, one firmware

Control every salt. Pick how many.

Every salt carries two ions, so element control is a solver over salts, not a jug per element. More channels widen what the solver can hit, at the cost of tubes, calibration and ways to go wrong. Same Root firmware on every tier.

Standard

The default for every Jardin kit.

Stock jugs sit on load cells; dashed jugs are optional channels.

5 channels: A, B, C, pH Down, and pH Up (optional, off by default).

Ratio control: Continuous N:P:K:Ca:Mg by changing the A:B:C ratio every day. No bottle swap at flip.
Accuracy, fresh batch: ±5 % on N, P, K, Ca and Mg in a fresh batch; sulfur is a by-product.
Pumps and verification: DC peristaltic, verified by weight.
Who it's for: The default for every Jardin kit.
Failure risk: Low to medium: three stocks, and the C jug is the one people mix up.

pH Down only, by default. Plants feeding on nitrate push pH up as they drink, typically 0.1–0.4 a day in a small reservoir, so every tier ships with acid and no base. pH Up is an optional channel the recipe switches on for ammonium-heavy feeds, fresh coco or organic inputs, with a day cap one third of pH Down's.

Per-element dosing · how the solver works

From a recipe to grams in the tank, checked twice.

The grower sets element targets. Jardin turns them into millilitres of each stock, doses in a safe order, waits for the mix, then proves it: by weight on every jug and by EC against its own prediction.

Salts as vectors
Each stock is a column of mg per mL: calcium nitrate pushes Ca and N together, MKP pushes P and K.
Solver
A small least-squares problem finds the mL of each stock that lands closest to the recipe, inside every safety ceiling.
Dose order
Calcium first into clean water at one inlet; phosphate and sulfate later at the other. They never meet concentrated.
Mix and settle
Circulate three reservoir turnovers after calcium, five minutes between the rest, then let the probe settle.
Verified by weight
Every jug sits on a load cell. The model books grams delivered, not what the pump was told, and EC must match the prediction.

Knowing what's in the tank · mass balance

EC is one number. We track thirteen.

Jardin keeps a running estimate of every element in the reservoir, with an honest error bar, from what it dosed by weight, what the plants drank and what drained away. A lab test resets it. When the estimate stops being trustworthy, it proposes a fresh batch.

Error bars that grow, then reset

Lab-test recalibration

Upload a nutrient-solution panel from an agricultural lab. The parser reads it, the model snaps to the measured values and refits the plant's uptake profile for that grow. Recommended every 2–3 weeks on Precision and Lab tiers; tap users add a water-source profile every six months.

When it dumps the reservoir

Any one trigger proposes a refresh; on Level 2 and up it schedules itself after a two-hour veto window.

Accumulationtop-off ≥ 100 % of volume (HPA 150 %)

Ions the plant doesn't take build up while EC still reads fine.

Uncertainty1σ on N, K or Ca > 25 %

The model no longer knows what it is holding.

The feedback loop · you talk, it adjusts

What happens when you type "the leaves look pale".

The grower talks like a grower. The system answers with readings, one small change, and a way out.

1 · YOU TYPE

Lower leaves yellowing, new growth looks pale, mist seems weaker than last week.

2 · STRUCTURED

chlorosis_lower   0.8
chlorosis_new     0.7
mist_weak         0.6

Anything outside the vocabulary is logged, never acted on.

3 · CORROBORATED

Zone 2 pressure drop per burst fell 22% vs the 7-day baseline. pH has sat at 6.3 for two days. EC is stable.

4 · PROPOSED

ph_target  -0.2  (3 days, auto-revert)
flush zone 2 now

One variable, inside the recipe band. Uncorroborated notes become a suggested check.

5 · YOU DECIDE

Greenleaf explains it with the readings and how many similar grows saw the same thing. Approve or keep. The outcome is tracked for three scans.

Fail-safes · planned for, not hoped for

In HPA a dead pump costs the crop in hours. Plan for it.

Every row below becomes a bench fault-injection test before any unit leaves the building.

Failure	How we detect it	What the system does
Pump dies	No current, refill never completes, pressure under cut-in for 90 s	Mist from the accumulator (6–10 bursts), then lifeboat mode; alert
Pump won't stop	Pump on >180 s, pressure never reaches cut-out	Hardware timer cuts it; relief valve caps pressure
Solenoid stuck closed	Normal current, no pressure drop on burst, chamber RH falling	Other zone at double rate, flush, lifeboat if RH stays low
Nozzle clog	Per-zone pressure drop down 25% (partial) or 60% (full)	Longer bursts up to +50%, flush, spare ordered, alert
Power cut	PSU sense	Battery runs the Root node, pump and lifeboat for 24 h+; dosing paused
Wi-Fi or hub lost	Missed heartbeats	Node runs its last 24 h plan; dosing stops after 6 h; misting never stops
Probe drift	Calibration slope, drift without dosing, stuck values	Half dose caps, no AI proposals on pH, calibration reminder
Acid overdose	Weight delivered over cap, pH under 5.2	Hardware timer limits runs; channel locked; plain-water dilution
Leak or overflow	Leak pad, high float, weight falling with no event	Hardware interlock drops the pump rail; loud alarm; manual reset
Root rot risk	Return water over 24 °C, pH/EC drift signature, root photos	Chiller on, mist tightened, UV-C if fitted, sanitation guide

Safety rules we don't bend

No mains inside anything we design.Low-voltage DC to every pump, valve and doser. Lights and fans switch through listed plugs.
Misting never waits for the network.The node keeps its last 24-hour plan, on battery if it has to.
Hardware gets the last word.Leak pads and floats cut the pump rail directly; max-on timers and a relief valve back up the firmware.
Normally-off outputs.Outputs start latched off, so a reboot or a dead board leaves everything off.
Acid is capped twice.Small steps, a daily cap, weight verification and a low-pH lockout.
Electronics above the water line.Sealed boxes, cable glands pointing down, a drip loop on every cable.

Sensors · what it watches

Built around what's already on the bench.

Most of these are already wired up on the bench. Everything else is added only where it earns its place.

Sensor	Where	What it does in this design
pH probe	Root	pH control and drift detection; isolated front-end so EC can't corrupt it
EC / PPM probe	Root	EC control, dose-effect check, HPA return EC; shows mS/cm and both ppm scales
Water temp	Root	Chiller control, EC compensation; second probe on the return line spots chamber heat
Air temp / RH	Climate, chamber	VPD and mould control; chamber RH ≥ 95% is the proof that misting works
Flow meter	Pump line	Litres per refill = litres delivered; a slow refill means a worn pump or clogged filter
Load cells	Reservoir, stock bottles	Water use, transpiration, leak detection, automatic reservoir changes, every dose verified in grams, bottle-empty 48 h ahead
Peristaltic dosers, pumps, solenoids	Root	A, B, pH up, pH down; HPA pump; mist zones; top-off and drain
Pressure transducer 0–150 psi	HPA line	Pump control, per-zone burst volume by pressure decay, clog and leak detection
Leaf IR thermometer	Climate	Leaf VPD instead of air VPD; the biggest accuracy gain for the effort
Floats and leak pads	Root	Hard interlocks that cut the pump rail in hardware
Camera	Hub	Canopy scans, sticky-trap counts, time-lapse; NoIR root camera on Pro
CO₂, DO, ORP, true PAR	Add-on / Pro	Only where they pay for themselves: sealed rooms, RDWC, sterile reservoirs

Nutrients and pests · mixed by weight

Mixed by weight. Pests watched, not sprayed.

A three-part mineral line designed for nozzles, mixed and verified on the stock-bottle scale. Pest control means detection, climate and guidance; anything sprayed stays human and unregistered products stay out of the box.

How a reservoir gets made

The app walks you through 100× stocks on the scale: "Add calcium nitrate until it reads 236 g."
Top-off fills the reservoir to a weight target (60 kg).
A, B and C are dosed by weight to the recipe's EC; the ratio changes daily, so no bottle swap at flip.
pH is trimmed last; EC verified; the batch is logged as a mix record.
Small daily corrections follow the same check. Bottles running low are flagged 48 h ahead, with a one-tap reorder.

Pest control: what's really automated

Automated: sticky-trap counts from the camera, with alerts on a 3× weekly rise
Automated: mould and mildew pressure via night RH and dew-point margin, fan proof-of-life
Automated: reservoir sanitation with a listed inline UV-C unit, interlocked to flow
Scheduled: biologicals and beneficial insects as reminders with sourcing
Human: spraying, inspecting under leaves, quarantine, disposal
Never: ozone in the room, or any pesticide claim

The ecosystem

Lights and fans that talk to the brain.

Works today with standard gear: common LED drivers dim over 0–10 V, and EC fans take 0–10 V or PWM. Next comes our own hardware, built on the same controller platform.

Now

Any 0–10 V light or fan

Jardin's PWM-to-0–10 V outputs dim standard LED drivers and EC fans, with sunrise and sunset ramps and VPD-driven fan speed. Wall-socket devices run through listed smart plugs.

Next · Jardin Link

A wireless dimmer puck

A small wireless module that plugs into any driver's DIM port or fan's control input and joins the Jardin hub over Wi-Fi and Bluetooth. No wires across the tent. Sold on its own, too.

Later · Jardin Light

Our own fixture

Quantum boards built to our spec, a quality LED driver, Jardin Link built in. Spectrum and intensity set by the strain recipe, day by day.

Jardin Light · concept · tap the channels

A light that reads the recipe.

The goal: our own fixture, built to our spectrum by an experienced fixture maker, with the Jardin Link inside. Four independently dimmable channels follow the strain recipe day by day: sunrise and sunset ramps, a daily light target, far-red at the end of the day, UV-A in late flower.

Planned

Challenges · named early

Sixteen hard problems, and our answer to each.

The things that sink grow-controller companies are rarely the clever parts. They are drift, water near electricity, bad updates, offline rooms and mixed-up jugs. Here is each one and what we are doing about it.

01Sensor drift and calibration

pH probes drift 0.1–0.3 a week, EC probes foul, and a controller chasing a bad number does damage.

How we handle it: Calibration intervals are enforced, a probe-suspect mode halves dose caps and blocks Level 3, weighed doses bound the damage, and replacement probes ship on age.

02Water and electricity in a home

Reservoirs, acid and pumps sit next to mains-powered lights and fans, often in a bedroom.

How we handle it: No mains in anything we design: listed power supplies and plugs only, low voltage everywhere, leak pads on a hardware interlock, coated boards, diluted acid and drip trays.

03Data privacy

Grow data is sensitive, and photos can carry location.

How we handle it: Location stripped on the device, region stored at state level only, consent per grow, full export and deletion, encryption at rest, and the room runs with sync off.

04Fake and duplicate genetics

The same seed sells under five names, and five seeds under one.

How we handle it: GB-IDs separate a verified account from verified genetics, every lineage link shows its evidence level, and duplicates are detected on name, breeder and parentage.

05Moderation at scale

Spam, scams and illegal listings grow faster than the moderator team.

How we handle it: Contribution-based reputation, fast triage with a human on anything uncertain, report and appeal flows, rate limits and a verified-breeder programme.

06Certification

Emissions with long sensor cables, pressure parts, a battery in the box, and a fixture listing.

How we handle it: Pre-certified radio modules, low-voltage design, emissions pre-scans at two board revisions, and the fixture listed through its maker's existing certification.

07Firmware updates in the field

A bad update on a dosing node is a lost crop.

How we handle it: Signed A/B images with automatic rollback, staged rollout 1 → 10 → 100 %, never during a dose, a mist or on battery, and a tested remote downgrade switch.

08Offline operation

Grow tents are metal-lined and the internet drops.

How we handle it: Nodes hold 24-hour plans, relay heartbeats to each other, the hub serves a local UI, and data syncs when the connection returns.

09Water chemistry varies by source

Tap water carries 20–200 mg/L alkalinity, calcium, magnesium and sometimes boron; RO has no buffer at all.

How we handle it: A water profile at onboarding feeds the solver, alkalinity is pre-acidified, RO gets a buffer, and a changed EC at fill raises a 'your tap water changed' alert.

10Simple for beginners, deep for experts

The same product must hide 13 element targets from one person and show them to another.

How we handle it: Automation levels gate what it can do; Starter users see recipe strength, Precision users the element table, and every number has a plain-language card.

11Stock solution integrity

Wrong jug, weak mix, crystals in a cold room, iron breaking down in light.

How we handle it: QR-bound jugs, refill detection by weight, an EC fingerprint dose after every refill, a cold-temperature lock and an opaque iron jug.

12Proving dosing is safe

'Software dosed acid into my reservoir' is a headline.

How we handle it: A hardware timer on the acid channel, diluted acid, 2 mL steps, weight verification, a pH 5.2 lockout, and published fault-injection results.

13Humidity and corrosion

Rooms at 90 % humidity kill unprotected boards within a year.

How we handle it: Conformal coating, sealed boxes with downward cable glands, gold-plated connectors, membrane-capped sensors, and the hub and power supply outside the tent.

14Smart-plug dependence

A plug's firmware update can break local control overnight.

How we handle it: One listed plug with a local interface, stock bought ahead, every plug firmware tested before it reaches growers, and a listed relay box for Pro.

15Clock and photoperiod integrity

A clock jump during flower can push a plant back into veg.

How we handle it: Network time checked against the real-time clock, nodes follow their own clock, large jumps need confirmation, and every lights event is logged.

16Heat from the hardware itself

Drivers and pumps warm small tents.

How we handle it: Driver plates mount outside the tent, pump duty is logged, and the climate loop counts fixture power as a heat source.

Why now · the work behind it

Years on the bench. Now the parts caught up.

Built by a grower who kept rebuilding the same system until it worked, at the moment sensors, boards and tooling became cheap enough for a small team to ship it.

The thing that changed is not an idea. The parts finally caught up.

The founder has spent years growing, building, breaking and rebuilding this system. The first GenetixBay existed before the market did; the grow controllers that followed were either expensive and closed or cheap and dumb.

Today the hardware that used to be lab equipment is the size of a grain of rice and costs very little. LED fixtures have doubled in efficacy in a decade and dim over a two-wire interface any small board can drive. Firmware frameworks ship with secure boot, signed updates and real-time scheduling as standard. Hubs run their services in containers that update themselves, and storing millions of sensor readings and serving them to a phone is a solved problem.

The law moved too: home growing is legal across most of Canada and a large share of US states. A small team with hands-on experience, a bench of working hardware and these tools can now build what used to take a company. That window will not stay open long.
