HortiNodeData-driven growing shouldn't cost a greenhouse.
The tools that let you grow professionally — real data, real control, real insight — were built for high-end commercial operations and imported climates. Most growers never get near them. HortiNode is lowering that barrier: affordable, locally built, and honest about what it does. We're starting with the growers who've been left out, and building from there.
See howThe gap
Most growers are running on guesswork.
Walk into most grows and you'll find the same thing: timers, gut feel, and hope. Growers find out something went wrong when they walk in and see it — not before. The tools that would tell them sooner, that would turn a grow into something measured rather than guessed, exist. But they're expensive, they're complicated, and they're built for climates and operations that have nothing to do with the conditions here.
So a whole population of capable growers stays locked out — not because they don't want to grow with data, but because the door has always been priced for someone else.
We know this because we're in the market every day. When we show growers that data-driven growing can start affordably — that it doesn't require a commercial budget to begin — they don't need convincing. The barrier was never willingness. It was access.
What we believe
Lower the barrier, and growers who were excluded can grow with data.
HortiNode makes professional-grade growing something you can start small and cheap. A grower can begin with a single node reading their conditions, add control when they're ready, and dose their feeding chart precisely — without a commercial installation or an imported system. When the barrier drops, three things change for a grower:
Data instead of guesswork
They can see what's happening, and they have a record of what actually happened rather than a memory of it.
The manual work, taken on
The watching, the dosing, the adjusting — so the grower can spend less time babysitting the grow and more time running it as a business.
Their own trail of data
Over time — what they grew, how, and how it turned out — becomes the basis for better decisions, with us helping them read it.
That's the change we're building toward: not just better crops, but growers with more time, more control, and a growing base of their own evidence to improve on.
Where we are
Real hardware. Real growers. A live pilot.
This is not a concept. HortiNode runs on real hardware, validated in real grows, with a pilot underway.
Monitoring and control
Nodes that read a grow's conditions in real time and act on rules the grower sets: turn the fan on, stop the pump if it runs dry, and report what happened.
Chart-driven dosing, honestly confirmed
A grower loads a real manufacturer feeding chart and the system doses the exact amounts for their crop's stage. Every dose is confirmed. If one can't be confirmed, the system holds the rest rather than guessing, and tells the grower exactly what happened. No black box.
A record that can't be faked
Every grow is captured as it happens: what was grown, on what recipe, in what conditions, with what result. This is the foundation that lets us measure impact rather than claim it.
A live pilot
With growers we already know, from our own network and client base. These aren't strangers recruited for a trial; they're people who already trust us, growing with us so we learn together.
How we'll know it worked
We built the tools to measure impact — not just assert it.
Most impact is claimed in anecdotes. Because we record every grow as structured data from the start, we can measure ours. Across the pilot, we're tracking:
Operational outcomes
Yield, consistency, and waste. Did the growing measurably improve, grow over grow — on the record rather than by recollection.
Time and focus
How much of the manual work the system absorbs, and what that gives a grower back: the headroom to work on the business instead of in the grow.
Capability over time
Each grower accumulates their own trail of data and, with our guidance, gets better at the decisions that trail informs. The record compounds.
We're honest about what one pilot season shows: the beginning of these trends, not the full arc. But the instrument to measure them is built and running, and every grow from here forward adds to the evidence.
The sequence
Start where the barrier is highest. Build from there.
We're deliberately starting with entry-barrier growers — the ones the expensive, imported tools have always left out. If data-driven growing can work for them, affordably and genuinely, then it can work anywhere. That's the test worth running first, and it's the one we're running.
The path up is already visible. Beyond the first pilot growers, we have mid-tier operations ready to grow with us — proof that lowering the barrier at the bottom opens a route upward, not a dead end. Entry is the mission; the growth is what follows.
And every pilot grower is someone we already know — from the market we supply, the relationships we've built. This isn't a trial run on a community we've parachuted into. It's us serving growers we already serve, with something new.
The horizon
Where it's goingA picture of what actually works — built here.
Every grow recorded on HortiNode adds to something that doesn't exist yet: a locally-grounded record of what actually works, in these conditions, for these crops. Not a dataset imported from a Dutch greenhouse and hoped to translate — a picture built from real grows, here.
As that record grows, HortiNode moves from telling a grower what is happening toward helping them see what's coming— from “your reading is off” toward “here's what to correct, and when.” That's the direction. It's built on the data the pilot is beginning to generate, and it belongs to the growers who generate it.
Why we can build this
We're not outsiders to this.
HortiNode is built by people already in the room with growers. We supply the nutrients and equipment growers rely on — we know these feeding charts because we sell them. We're at the markets and the expos. We understand what it means to grow through a Cape Town summer, through load shedding, through the gap between what a crop needs and what a grower can actually give it.
That's not a pitch. It's a position. Our first growers are our own clients and contacts, which means we can't build this, run a trial, and leave — we're embedded in the sector we're serving, and we'll be here after the pilot ends. The people we're building for are the people we already answer to.
With the support of
This work is backed, and progressing — supported by a leading South African institution's impact programme, with further funding secured. We're grateful for the partners who have helped us get here, and who are helping us build what comes next.
We're building this in the open — and with the people who use it.
We're at the beginning, and we'd rather be honest about that than oversell it. What's built is real. What's ahead is clearly ahead. And everything after this gets built with the growers who are actually using it. If you'd like to follow where this goes, or talk about it, we'd welcome it.
