We've rebuilt our app from the ground up. Every screen, every graph, every line of code. It's called GrowOps, and the GrowOps app lands on iPhone and Android next week.
I've been growing for over twenty years, and I wanted an app that answers one question fast: how's my room doing right now? So we started again, with one rule. Open the app, know your room.
It's built for the modern grower. One tent in the spare room, or a racked facility with a team on shift. Same app, same sensor, and it grows with you.
A proper app for the grow room floor
The old app did the job. The new one feels like it belongs on your phone. Big clear titles, a floating tab bar, everything one thumb away while the other hand is in the canopy.
Your Grow Sensor PRO reads leaf temperature, true leaf VPD, air temperature, humidity, CO₂ and light. GrowOps puts all of it on one screen per grow, live, with the full history behind it.
Set a limit and GrowOps tells you when a reading leaves it. The alert lands on your phone, so you're not finding out the next morning.
And it's free. Download it next week, set up your sensor from the phone, and you get live readings, alerts and unlimited history at no cost. One sensor per room stays free forever, up to six sensors.
Grow Plus: the full kit
If you want to really dial it in, Grow Plus gives you the lot. £9.99 a month or £99.99 a year, with the first month free. You buy it inside the app.
Here's what you get:
- GrowOps on your computer at grow-ops.io, with every graph and diary entry on a big screen.
- Advanced recipes. Split each grow into phases, from veg to stretch, bulk and ripen, each with its own limits and length. Your best grow becomes the template for the next one.
- Smart Limits. A suggested range for every reading in every phase, approved by our agronomist and fitted to your own grow's readings.
- A professional grow diary. Snap photos and log plant height, runoff pH, every feed and every prune. Each entry sits on your graphs, so you can see exactly what the plants responded to.
- Grow health. One score for the whole grow: how much of the time every reading stayed inside your limits, and which one slipped the most.
- Crop steering metrics. Add a substrate sensor and the Steering card shows whether your watering is steering the plants vegetative or generative.
- The full light spectrum, blue to far red. Check what a lamp really puts out, not what the box says.
That's your recipe book, your grow diary and a light meter, in one app.
GrowOps for facilities
This is where it gets serious. GrowOps for facilities runs every room, every run and the whole team from one place.
- Rooms and zones that match your building. If you run racks, give each tier its own zone and its own sensor.
- As many sensors per room as you need, all on the same graph.
- Plants that move rooms keep their history. Every phase of a grow knows which room it ran in, so clone to cure is one record.
- Recipes as templates, with day and night limits on every metric.
- The whole team. Invite people by email as owner, admin or member, with no seat limit. GrowOps is priced by sensors, not people.
- More than one site under one login, and alerts that say which facility they came from.
- A cultivar library and grow reports.
Use it on a tablet in the room, on the TV in the control room, or at your desk. GrowOps starts from £99 a month. Have a look at everything it does or the facility pricing.
Already on the Grow Sensor app?
You don't need a new account. When GrowOps lands, download it and sign in with your usual Grow Sensor login. Your sensors will be there waiting.
Your old grows come across now. We're moving them over on our side, so you don't have to do anything.
The old Grow Sensor app keeps working in the meantime. If you keep both on your phone, you'll get alerts from both, so switch notifications off in the one you're not using.
Works with the original Grow Sensor too
The new app works with both the original and the new Grow Sensor, so no worries there.
What's coming next
We're not done. Coming soon:
- Bluelab, with reservoir pH, EC and temperature right next to your Grow Sensor readings.
- Growlink, both ways: Growlink data in GrowOps, and Grow Sensor data in Growlink.
- ChatGPT and Claude, so you can ask questions about your own grow data.
Home Assistant works today, and the API is available on request if you want to build on it. See all the integrations.
Get the GrowOps app next week
GrowOps will be free to download on the App Store and Google Play next week. Pair it with a Grow Sensor PRO and see what your room is really doing.
