Niwa Grow Hub

With the all new Grow Hub, Niwa brings commercial grade features, such as controlling your plant’s climate (humidity, temperature and VPD) or automated watering and custom light schedules to the domestic grower at an affordable price.

With the goal of supporting a hassle free and high performance grow, Niwa has developed powerful software that enable growers to automate their setups in a very simple way- just by having users plug  their existing devices (such as lamps, fans, extractors, humidifiers, dehumidifiers, A/C, pumps, or heaters) to the Niwa Grow Hub.

Live Dashboard

For those moments when growers are concerned about what’s going on in their garden, there is no need to worry anymore! With the Niwa Grow Hub app, growers can now check the current status of their garden by glancing at their live dashboard, anytime, anywhere, and in a secure way.

Grow Recipes

Once the Niwa Grow Hub app is up and running, growers can either pick one of the existing Niwa grow recipes or create one themselves. It is at this step, when creating a grow recipe, growers can begin to customize the ideal environment they’re seeking and the different schedules wanted for their plants. Environmental settings such as VPD, temperature, humidity along with watering and light schedules are all completely customizable, so growers have optimum control over their plants.

Recipe Stages

Plants have different needs in terms of their climate, lighting schedule and how much water is required throughout different times of the day. Creating a grow recipe within the Niwa Grow Hub app allows for several stages to define the different parameters needed for each stage of a plant. To continue building out a grow recipe, growers need to select the “next stage” button in order to customize their setting per stage within the plant’s growth cycle. 

Alarms & Notifications

Having alarms and notifications will allow growers to determine the temperature and humidity thresholds important for them and alert growers when their lamp is performing poorly and also for when one of the sensors is having an issue.

Outlet Configuration

Every growers setup is unique to their needs and the Niwa Grow Hub allows users to keep their setup and automate at the same time. Growers can configure their Niwa Grow Hub to control up to four of the following devices at the same time:

  • Fan
  • Lamp
  • Humidifier
  • Dehumidifier
  • Cooler (A/C)
  • Heater
  • Watering Pump

Each outlet is capable of handling 10A (resistive load) either at 125V or 240V for a total of 15A MAX. Larger loads can be handled through accessories (not included). 

Please Note: The Niwa Grow Hub is capable of handling input/output voltages either 120Vac or 240Vac. If you plug your Niwa into a 120Vac wall outlet all the four outputs will be 120Vac, if you connect it to a 240Vac wall outlet all the four outputs will be 240Vac. The most common household voltage in the United States and Canada is 120V, however, some growers might have access to a 240V grid. If that’s the case, please make sure all your devices work with 240V.


Logging & measuring the different parameters affecting a crops success is fundamental in order to achieve maximum performance. The Grow Hub has a built-in datalogger accessible from our app anytime where you can view historical data in the ‘stats’ section and get insight to how your plants are doing and what is affecting them.

Automation In Minutes

Building a setup capable of monitoring and automatically controlling growing equipment simultaneously is often difficult as it will require different devices such as temperature, humidity, or ventilation controllers and monitors, which adds cost and complexity. The Niwa Grow Hub combines all the control of multiple pieces of grow equipment into one single device and app, easing plant management and reducing the risk of making mistakes at an affordable cost.


The Niwa Grow Hub incorporates the reliable WiFi 2.4Ghz standard to guarantee growers' access to their plants from anywhere, at any time. Also, Niwa has built strict security protocols into their software to guarantee absolute privacy and protection.

Over-The-Air Firmware

The Niwa Grow Hub is enabled with Over-The-Air Firmware and app updates that guarantee the latest features are instantly accessible to all growers. On top of that, the Niwa Grow Hub is fitted with the Niwa Grownet standard that will connect growers with the next generation of Niwa Grow devices effortlessly and wirelessly.


Monitoring is important to avoid fatal mistakes and earn maximum yield. But it is not enough. If your setup cannot automatically control the lamps or operate the different equipment to automatically correct a risky situation such as excess of temperature, when your monitor warns you, it may be too late. The Niwa Grow Hub closes the control loop for your peace of mind.
