Be first to grow smarter with Grow Sensor PRO

The wait is nearly over — and we couldn’t be more excited.

After months of testing, refinement, and invaluable feedback from our beta users, we’re thrilled to announce that pre orders for the Grow Sensor PRO will officially open on May 20.

And with only 100 units available, this first release is strictly limited.

A one-time opportunity to be among the very first to level up your grow with professional-grade insights.

Why pre order?

Whether you're a home grower looking to optimise your setup, a commercial cultivator chasing precision, or a tech-forward hobbyist who loves dialling in every detail, the Grow Sensor PRO is for you.

Designed from the ground up to deliver real-time, actionable data, our sensor helps you grow smarter, respond faster, and get more from every cycle. 

From humidity and temperature to VPD and beyond, you’ll have the data you need when you need it.

This initial launch is more than just a product drop. 

It’s our way of thanking early supporters with first access, hands-on experience, and a direct line into the Grow Sensor journey as we continue to evolve.

Only 100 units are available in this limited release, each part of a carefully produced first batch crafted with attention to detail and a strong commitment to quality.

When will my order ship?

All pre-orders will ship between June 9 and June 23.

That gives us time to complete production, run final quality checks, and ensure each sensor is securely packaged and ready for your grow space.

You’ll get a confirmation email immediately after you order, and we’ll keep you updated every step of the way. 

As soon as your sensor is dispatched, you’ll receive a tracking link straight to your inbox.

When will I be charged?

Payment will be taken at the time of pre-order.

This locks in your unit from the limited first batch and allows us to plan production and logistics with the accuracy and care our early customers deserve. 

Your order confirmation will arrive straight away, followed by timely updates as we move through the final stages.

A quick note on import duties

If you're ordering from outside the UK, including Europe, the US, or anywhere else, please note that import duties or local taxes may apply, depending on your country’s regulations.

These charges are typically collected by your local courier service and are not included in the pre order price. 

If you're unsure, we recommend checking with your local customs office so you know what to expect.

What to expect after you pre order

We believe in building more than just a product - we’re building a community.

When you pre order Grow Sensor PRO, you're not just getting early access to our flagship sensor. 

You’re joining a growing movement of cultivators who believe in data, precision, and pushing the boundaries of what’s possible.

Here’s what happens next:

  • ✅ You’ll receive regular updates so you always know what’s happening

  • 📦 You’ll get a tracking link as soon as your sensor is shipped

  • 💬 You’ll have access to our support team if you need any help

  • 🌱 You’ll become part of the earliest Grow Sensor community, shaping what comes next

Thank you for growing with us

This is just the beginning, and we’re so grateful to be launching it with you.

From a handful of prototypes to a full-fledged product built with care, your feedback, enthusiasm, and support have made all the difference. 

Every sensor we ship is a step forward in our mission to help growers everywhere unlock more potential from every plant.

If you have any questions, before or after your order, we’re always here to help.

Mark your calendar: May 20. Pre orders go live. Let’s grow.
