Every grower has the itch.
The at-a-glance view that doesn't exist in any dashboard you own. The compliance export someone on your team rebuilds by hand at the end of every month. The alert that should has to be filed the moment it arrives at 2 AM, but instead sits in a queue nobody is watching.
For years, that itch had two paths. Wait for us to build it — and hope your request survived the roadmap. Or bend your workflow to fit whatever generic default shipped in the box.
Today there's a third option.
Build it yourself. Right inside Growlink. This week.
What is the Growlink App Builder?
The App Builder is a platform built into your existing Growlink portal that lets you create custom apps on top of your cultivation data.
Your sensor readings. Your device states. Your climate setpoints. Your irrigation history. Your harvest records. All of it is live, structured, and ready to build on — not exported to a spreadsheet once a week, but available right now, exactly as it exists in your facility.
The App Builder gives you two ways to build. One for operators who have never written a line of code. One for developers who want to go as deep as the data goes.
For operators: Tell Nova what you want.
You don't need to know how to code.
You don't need to understand APIs or webhooks or any of that. You don't need a developer, a software team, or a technical background of any kind.
You just need to know what you want.
Nova is Growlink's AI builder — built into the App Builder and ready to work. Describe the app you want in plain English: every sensor the code connects to your cultivation data, and creates a working app inside your Growlink portal. On the spot.
You type, "Build me a dashboard showing live temperature, humidity, and CO2 across all my rooms with color-coded alerts when anything goes outside my setpoints."
Nova builds it. Four rooms. Four sensors. Your data. A working app in under a minute.
That's the entire process.
No downloads. No setup. No waiting. If you can describe what you want, Nova can build it.
Some prompts to get you started:
- Build me a live view of all my rooms showing temperature, humidity, CO2, and VPD with alerts when anything goes out of range.
- Build me a dashboard that shows my waste tank levels, pH, and EC in real time.
- Build me an app that tracks dryback percentages by room and compares it to my target recipe.
- Build a compliance log that records environmental conditions every hour and lets me export a report for inspectors.
For developers: The full API is open.
If you write code, the Growlink API gives you direct access to everything your facility generates.
Sensor telemetry. Device statuses. Climate setpoints. Irrigation history. Nutrient delivery. Harvest records. All of it, programmatically accessible through standard REST and JSON interfaces. No proprietary SDK to learn. No credential required. If you can code, you can build on Growlink.
And it goes past read-only. You can push decisions back in — adjust climate setpoints, trigger irrigation events, fire alerts — within the permissions you set. A dashboard can show you the dryback shift; an application can act on it.
The Developer Tools, API Explorer, and Codebook are all live inside your portal. Test any endpoint against your real facility data before you write a single line of code.
What operators are already building
Since the launch of the App Builder, operators have built over 100 custom apps.
A few that stood out:
- Fertigation Live 2.0 — a live dashboard showing zones, tanks, pH, EC, and flow history at a glance.
- DrybackIQ — overnight dryback insights from substrate moisture data, one night at a time.
- Compliance Logger — logs environmental sensor data automatically and generates a printable compliance report on demand.
- Blueprint Room Match Mapper — upload your facility floor plan, map your grow rooms onto it, and see live environmental metrics overlaid on your actual layout.
- Crop Steering Dashboard — dryback percentage, irrigation frequency, shot volumes, and overall EC with clear target overlays.
Before the App Builder, these solutions didn't exist. The growers who built them aren't developers. They're growers and facility managers who knew exactly what they needed and finally had a way to build it.
Share what you build
When you build something worth sharing, you can share it.
Every app you build gets a Share ID. Send that ID to any other Growlink operator and they can install your app in their portal in seconds. No files to transfer. No setup on their end.
One shared build is something great. Every operator benefits.
What's coming
Nobody is done creating.
Soon you'll be able to upload photos — a plant, a root zone, a sign of pest pressure — and ask Nova what it sees. Nova will analyze the image against your sensor history, and tell you what's going on.
You'll be able to ask Nova questions that span your entire facility: "Why did humidity spike in room One Tuesday?" "Which of my rooms has been running the highest VPD this week?"
And Nova will start helping you catch patterns you're missing — watching so every problem becomes known, not after.
We are operators building on the platform today and we keep shipping what it becomes.
If you're a Growlink customer, the App Builder is already in your portal.
