Product Description

Optimize your Garden’s Performance with VPD Management

Achieve optimal growth and health for your plants with the Niwa Grow Hub+ VPD management system. Our system allows you to monitor and adjust vapor pressure deficit, which affects your plant’s ability to absorb nutrients, regulate temperature, and capture CO2. By controlling VPD, you can ensure your garden is performing at its best. For even more precision, you can upgrade with our CO2 sensor (monitor and control CO2 levels).

Stay Connected and Get Peace of Mind from Anywhere with Niwa Grow Hub+

The Niwa Grow Hub+ connects to Wi-Fi and stays connected to the internet storing crucial data about your indoor garden on the Niwa Cloud, 24/7. You can view your live data from anywhere, anytime, with the Niwa app on your iOS or Android device. Please note the Niwa Grow Hub+ only connects to 2.4GHz Wi-Fi networks, which is compatible with the majority of home routers.

Effortlessly Control Your Indoor Garden Setup

Transform your indoor garden into a smart garden with the Niwa Grow Hub+. Manage up to 4 pieces of equipment simultaneously, automate up to ten indoor gardens under one username, and create custom climate settings tailored to your garden. The maximum capacity for the entire Grow Hub+ is 15A. You can automate your lamp, pump, heater, cooler, watering pump, humidifier, dehumidifier, or fan. You can automate a CO2 device for greater precision (optional upgrade).

Avoid Disaster & Stay Informed with Notifications Anytime, Anywhere

Set your target temperature and humidity and receive push notifications via the Niwa App if your garden’s climate is off-target. You can enable the blown lamp alarm to alert you if your lamp performance is reduced or if it’s completely off. Plus, get notified if any sensor malfunctions are detected. Never worry about your garden’s health again, even when you’re away.

High Resolution Sensors for Accurate Environmental Monitoring

The Niwa Grow Hub+ features high-resolution sensors for precise monitoring of light levels, temperature (accuracy of 0.015ºC), and relative humidity (accuracy of 0.01%). Proper placement of the sensor is crucial for obtaining accurate readings, and the 10-foot-long cord provides placement flexibility. You can upgrade with a CO2 sensor to monitor and control CO2 levels. With accurate and reliable sensors, you can optimize your growing conditions.

Tailored Grow Recipes for Optimal Plant Growth

With the Niwa Grow Hub+, you can create custom Grow Recipes with specific settings for each stage of your plant’s growth cycle. This allows you to provide the optimal environment for your plants, whether they are in the seedling, vegetative, or flowering stage. You can customize temperature, humidity, light, and watering cycles for each stage, making it easy to switch between stages with just a tap in the Niwa app. This ensures your plants receive the best care and achieve their full potential.

Niwa Grow Hub FAQ – Please read before buying.

What kind of Wi-Fi router do I need? Is the Grow Hub compatible with 5GHz Wi-Fi networks?

No, it’s not. The Niwa will connect to 2GHz Wi-Fi networks only. Most routers are 2.4GHz compatible. Some routers enable Wi-Fi networks for both 2.4GHz and 5GHz networks under the same name, so if this is the case, you might need to momentarily disable the 5GHz for the first setup. If you have a 5GHz or a mesh Wi-Fi network, the setup could be difficult, and it may require changes to your router settings. Please make sure you have access to your router settings and understand how to edit them. The Niwa Grow Hub+ requires a password-protected Wi-Fi network with access to the Internet.

How do I get assistance? If you have any issues or questions, please contact our support email which can be found on our Amazon listing (Important information section), the Niwa app (Gear Icon on the top right of the dashboard), or on our website. Please include the registered email you use to log into the Niwa app. You can check our forum on our website. If you want, you can call 312 725 6408 for support as well. Additionally, the Niwa Grow Hub online manual can be found on this listing under ‘Product guides and documents’.

How does the Grow Hub control the different equipment plugged into it? All connected pieces of equipment are managed automatically by your custom grow recipe (read our online manual to learn more, which can be found in the Product guides and documents of this listing).

Can I plug large pieces of equipment into the Niwa Grow Hub? The Niwa Grow Hub has been designed for small grow set-ups, so it’s limited to 15A MAX resistive loads MAX per outlet or 15A resistive load MAX TOTAL for the 4 outlets. If you want to use large ballasts, A/C units, etc. you must use the Niwa as a trigger with an external relay. Please note, these are resistive loads. If you are not sure about the power factor of your assigned pieces of equipment, we recommend not exceeding 500W (800w for Grow Hub +) for LED, HPS lamps, or any other non-pure resistive load. If you have any questions about the equipment you plan to use, you can always email our support team in advance.

Can I plug my A/C unit into the Niwa? No, you cannot. Please read our manual first (attached to this listing), since many A/C units draw more power than stated and this can damage your Grow Hub.

Will you be adding new features to the product? Can I benefit from them?

Absolutely! We are always working to improve our product based on the valuable feedback we receive from our customers. You can stay up-to-date with the latest developments by checking our community forum, where we actively engage with our users. When we release new features, we make sure that all our customers can benefit from them, either via free app updates or OTA firmware updates. Rest assured that you won’t miss any important updates as we communicate all new features to our entire community. And the best part? All updates are completely free of charge.

Is a”daylight threshold” (light %) required to turn on the CO2 outlet?

Yes, that’s correct. If the light level percentage is below the set threshold, the CO2 control doesn’t activate, as it assumes it’s nighttime.

Is there an upper trigger (max ppm) to stop power to the CO2?

The CO2 outlet will switch off as soon as the target CO2 is met. Additionally, there is a dead band of 50 PPM.

I just received my CO2 sensor, and it doesn’t work.

If you received a CO2 sensor, plugged it into your Grow Hub, and if it’s not working, it is most likely because you’re not running the latest Firmware. Please contact our support email which is shown on our listing and website and provide your registered email so we can update your device’s Firmware ASAP.
