About this app
Grow Sensor is a powerful environmental monitoring system that gives you full control over the conditions in your grow space. Paired with the companion app, it allows you to monitor key climate variables in real time and view detailed historical trends to improve your growing results. Whether you’re managing a single plant or a full grow room, Grow Sensor helps you understand and optimize your environment like never before.
At the heart of the system is the Grow Sensor device—engineered for accuracy, reliability, and simplicity. It captures high-resolution data on environmental variables that matter most to plant health, including temperature, humidity, vapor pressure deficit (VPD), dew point, and atmospheric pressure. This data is sent directly to the app, where you can access clear visual insights and make more informed decisions. A clean, intuitive dashboard gives you a complete view of your environment, making it easy to understand what’s happening at a glance or dive deep into long-term trends.
The app is designed to support every type of grower, from beginners looking for more consistency to experienced professionals seeking absolute precision. Detailed graphs allow you to track fluctuations over time and understand how each adjustment affects your environment. Whether you’re tuning ventilation, adjusting lighting, or fine-tuning your irrigation schedule, Grow Sensor puts accurate data at your fingertips to help you grow with confidence.
A key strength of the Grow Sensor system is its ability to make complex data simple and actionable. VPD, often misunderstood or overlooked, is tracked and visualized automatically—helping you stay in the ideal range for healthy transpiration and steady growth. The app also monitors dew point and pressure, offering early signs of imbalance or shifts in conditions. By tracking these variables together, you get a full picture of your grow space and can respond proactively before issues escalate.
The Grow Sensor hardware is compact and wireless, making it easy to place wherever it’s needed—at canopy height, near airflow sources, or alongside sensitive areas. It connects seamlessly to the app and works right out of the box, with no hubs or complex setup required. A long-lasting battery and USB-C charging make it easy to maintain, and firmware updates ensure your device stays accurate and secure over time.
The system is also designed to grow with you. For those looking to monitor root zone conditions, an optional connector allows substrate sensors to plug directly into the device. This opens up an additional layer of insight, allowing you to track substrate temperature and electrical conductivity (EC)—both crucial for maintaining the right moisture levels and nutrient balance. As your growing setup evolves, your sensor evolves with it.
Privacy and data ownership are core principles of Grow Sensor. Your information is encrypted, never sold, and always under your control. We believe growers should fully own their data and use it to support their success—never at the cost of privacy or independence. Whether you’re growing at home or in a larger space, the system has been designed to offer clarity, control, and peace of mind.
Grow Sensor is the result of deep collaboration between growers, engineers, and product designers who understand the real-world needs of plant cultivation. Every detail—from the design of the app to the simplicity of the hardware—has been shaped by hands-on testing and feedback. The result is a system that feels like a natural extension of your grow space, making it easier to achieve better results with less guesswork.
With Grow Sensor, you’re no longer growing blind. You’re growing with clarity, backed by real data, and supported by the tools to take full control of your environment. Download the app, connect your sensor, and unlock the potential of precision growing.
