120 days. Try us. If we can’t get your operation under tighter control, return the system.
We refund the hardware purchase and the software subscription paid to date. No restocking fee. No “we tried.” Below, exactly how it works. And what we ask of you in return.
Why we offer this
Every grower we sit down with comes to us with a problem. Irrigation that’s hard to fine-tune. Disease pressure you only spot when it’s already visible. A climate computer that tells you the past but not the future. Drainage you suspect is wrong but can’t prove.
We’ve spent ten years building the sensors, the dashboard, and the workflow that help growers get those things under control. What we cannot guarantee is a percentage. Your crop, your substrate, your team, your weather. Too many variables we don’t control. What we can guarantee is the system we put in your greenhouse, and the way we work alongside you to make sure it earns its place.
So here’s the deal. Install Sigrow. Work with us for 120 days. If at the end of that you decide we haven’t helped you get your operation under tighter control, send it back.
How it works
Step 1: Before you buy
We listen to the problem.
Your success manager sits with you and listens to the problem. What we recommend depends on your crop, your substrate, and your existing setup.
Step 2: Install and onboard properly
Multiple sessions across the first growing season.
Your success manager plans multiple sessions with you across the first growing season.
Within 30 days. First review. Virtually or in your greenhouse. We look at what the data is showing, what you’ve already changed in response, and whether the alerts are reaching the right people.
Within 90 days. Mid-point review. By now you’ve made decisions based on the data. We compare them to what you used to do.
Between sessions, our door is open. Technical support 9:00–21:00 CET, Monday–Friday. [email protected]
Step 3: Day 120, you decide
If it hasn’t earned its place, you tell us.
If Sigrow has helped you bring your operation under tighter control, we keep working together. If you can’t honestly say it has, you email [email protected]. We refund the hardware purchase and the software subscription paid to date.
What’s refunded, what we ask of you
We refund the hardware purchase, and the software subscription paid during the 120-day window.
You arrange and pay return shipping. This keeps the guarantee operational. It’s a real promise for real prospects, not a free trial for refund tourists.
The equipment comes back in as-good-as-new condition. All parts returned, sensors not modified, no physical damage outside normal greenhouse use. Normal use includes dust, humidity, and light bracket wear from mounting. Damage includes cracked enclosures, missing parts, and attempted teardowns.
Customized hardware is non-returnable. Standard Sigrow systems are covered by this guarantee. If your order includes hardware built or modified specifically for your operation, like non-standard sensors, custom mounting, bespoke firmware, or integrations beyond our standard climate-computer APIs, those units fall outside the guarantee.
Anything in between, we handle case-by-case and tell you honestly what we can and can’t refund.
Frequently asked
Who decides if equipment is “as good as new”?
We do, after inspection. But we tell you what we found and show you the unit. It’s not a judgment we make in private.
How long does the refund take?
Once the equipment is back and inspected, the refund is processed within 10 business days.
Can I extend the 120 days?
The window is 120 days from the day the sensors are delivered. We don’t auto-extend, but if there’s a genuine reason like a late harvest or an installation delay on our end, we can talk.
Does the guarantee cover the climate-computer integration work?
Yes. If you paid us to integrate with your Priva, Hoogendoorn, Ridder, Argus, or HortOS, that’s refunded too.
Can I keep some hardware and return the rest?
We handle partial returns case-by-case. The cleanest path is full return, but if you want to keep, say, the Soil Pro+ sensors and return the Stomata Camera, we’ll work it out.
What counts as “customized hardware” that can’t be returned?
Anything built or modified specifically for your operation: sensors with non-standard specs, custom mounting hardware, bespoke firmware, or integrations beyond our standard APIs.
