HortiNodeYour grow, under control.
From anywhere.
Most growers only find out something went wrong when they walk in. HortiNode gives you visibility and control over your grow in real time — from a single tent to a tunnel farm.
Monitoring is free — and stays free. You pay only when you want the system to do more.
Who we are
We're already in the room with growers.
HortiNode started from a simple frustration: the tools for professional growing are too expensive, too complicated, or built for climates that have nothing to do with here.
We're growers and builders who decided to fix that — from the inside. We supply the nutrients and equipment growers already trust; we know these feeding charts because we sell them. We're at the markets, in the tunnels, in the conversations.
Our first growers are people we already know and serve. We're not visiting this sector — we're part of it, and we'll be here after the pilot ends.
Sound familiar?
You checked the grow this morning. By afternoon, something had already gone wrong.
You're running on timers, gut feel, and hoping nothing fails while you're away.
You know something is off — but you don't know what, where, or how long it's been like that.
HortiNode changes that.
Know within seconds. The moment something moves outside the range you set, you get an alert — on your phone and by email. Temperature, humidity, water levels — in real time.
It acts on your rules — and tells you the moment something's wrong. Set your rules once; HortiNode acts on live sensor readings and tells you what it did.
Every reading, timestamped. A full history of what happened in your grow — not a guess. Real data you can actually use.
What it does
Everything you need to run a grow.
What's running today — not a wishlist. We set up your base nodes; you get a live dashboard from any device.
See it from anywhere
Live conditions on your phone — temperature, humidity, light, plant stress (VPD), water temperature — as they happen, with a full timestamped history.
It acts on your rules
Set your rules once. HortiNode acts on live sensor readings — and tells you the moment something's wrong, by push and email.
Your equipment, not ours
HortiNode switches the industry-standard equipment you already use: irrigation solenoid valves, pumps, fans, lights on your schedule, dosing pumps. Off-the-shelf gear, controlled by your rules.
Dosing that tells the truth
Dose your feeding chart with pumps you calibrate by hand — jog, measure, record. Every dose is recorded before it fires and confirmed by the node on completion. If a dose can't be verified it's marked unconfirmed — never faked, never silently retried. It never tells you a dose happened when it can't confirm it.
Grow programs
Run a crop program stage by stage — your nutrient chart and targets built in, with a record of every grow to learn from. Terra Aquatica is loaded today; more nutrient lines as we validate them.
A grow advisor
Guidance that reads your grow against your crop's stage targets and tells you what to bring back into range.
Inside vs outside
See what's happening inside your grow against what's happening outside — local weather and forecast alongside your live readings.
Data you can trust
Bad sensor readings are rejected — never stored. The system knows the difference between a sensor glitch and a real problem, so when you get an alert, it means something.

Ordinary hardware. Open if you want it.
HortiNode runs on ordinary, off-the-shelf hardware you can buy locally. We set up your base nodes for you — simple by default. And if you're the type who builds things, the platform is open for you to build on.
No proprietary lock-in — some brands lock you out of your own equipment's WiFi and charge for the uplink. We don't. Standard gear works, and it stays yours.
Our nodes are ICASA-certified and low-voltage only; mains switching is handled by certified Shelly devices built for it. Certified at every layer — dangerous voltage only ever touched by purpose-built hardware.
Who it's for
Whether you grow one plant or ten thousand.
HortiNode grows with you — without locking you into a tier you've outgrown. Start simple. Expand when you're ready. Indoor, outdoor, tunnel, greenhouse.

Getting started
The hobbyist grower
You're running a tent or a small outdoor setup — maybe both, depending on the season. You want to know what's happening without being there. One SpaceNode gets you live conditions on your phone. Start here.
🏗️
Growing seriously
The serious grower
You're running a tunnel, a hydroponic setup, or a small commercial operation. You need monitoring and control — lights, fans, pumps. HortiNode acts on your rules so you can focus on the crop.
🏭
Commercial scale
The commercial facility
Multiple zones. Multiple sites. You need a system that scales across locations and gives you a single view of everything. HortiNode is built for this from the ground up.
Where we are
HortiNode runs today in real grows — starting with our own.
We'd rather be honest about what's built than oversell it. Here's the line.
- Live monitoring from anywhere
- Rules-based automation on live sensor readings
- Instant alerts — push and email
- Calibrated dosing that reports honestly
- Grow programs, stages and harvest records
- A grow advisor against your stage targets
- Outdoor and field growing
- An on-site controller that keeps running if the internet drops
- Sensing-driven dosing (closed-loop on pH / EC)
- A growing agronomist program library
- Predictive guidance — not just what is, but what's coming
Pilot growers help shape what gets built next.

Western Cape · Applications open · Small groups
Apply to grow with us.
We're choosing our first growers by hand — for fit, not first-come. We read every application, and we build the pilot around the growers we take on. Their feedback shapes the platform.
Applications stay open — we review every one as it comes, and onboard in small groups we can support properly, starting spring 2026. Not everyone gets in — but every application helps us build the right thing.
