AC Infinity HYDRONE 5 – Smart plant dehumidifier with VPD control & 10-step precision control

Optimal climate for healthy plants and maximum yields

The AC Infinity HYDRONE 5 is a next-generation plant dehumidifier developed specifically for indoor cultivation, which regulates humidity and VPD (Vapour Pressure Deficit) values with exceptional precision. Thanks to state-of-the-art dehumidification technology and intelligent control options, the HYDRONE 5 creates ideal conditions for healthy growth, vigorous flowering and greater resilience in your plants.

With its powerful dehumidification, the HYDRONE 5 is ideal for grow tents up to approx. 1.0 × 1.0 metres and reliably ensures stable climate conditions throughout the entire plant cycle – from seedling to harvest.

Next-gen dehumidification technology for indoor grows

Unlike conventional dehumidifiers, the HYDRONE 5 has been specifically developed to meet the requirements of modern grow environments. Its proprietary system ensures reliable dehumidification in both warm and cooler climates and enables particularly low humidity levels to be achieved.

Two integrated 150 mm air inlets allow the targeted supply of dry air directly into the grow tent. Additionally, the dehumidifier can be used in closed-loop systems to further optimise climate control.

High-precision PWM rotary motor with 10 power settings

At the heart of the HYDRONE 5 is the innovative PWM-controlled rotary motor, which enables significantly more precise control than conventional compressor-based dehumidifiers.

Thanks to the 10 individually adjustable dehumidification levels, the system reacts immediately to changes in the climate and adapts its output precisely to current conditions. This minimises fluctuations and creates a consistently stable climate.

Advantages of PWM technology

• Immediate on/off response
• Higher control accuracy than conventional dehumidifiers
• Constant dehumidification performance
• Optimised VPD control
• Efficient energy consumption

Compatible with Controller 69 PRO & Controller AI+

The HYDRONE 5 can be connected directly to AC Infinity Smart Controllers via the integrated UIS™ port.

Supported functions:

• Wi-Fi app control
• Humidity automations
• VPD-controlled climate regulation
• AI-supported climate adjustments
• Real-time data logging
• Climate charts & trend analyses
• Push notifications
• Custom schedules
• Advanced grow automations

When used with the Controller AI+, the system even analyses past climate data and automatically optimises control for maximum efficiency.

Note on closed-loop operation

The HYDRONE 5 operates with a high dehumidification capacity. As with all dehumidifiers, this generates additional heat.

When operated as a stand-alone unit outside a closed system, this usually results in only a slight increase in temperature.

For optimal results, AC Infinity recommends:

• Control in VPD mode
• Combination with an exhaust air system such as the CLOUDLINE series
• Active temperature control via fresh air supply

This ensures that temperature and humidity work together optimally, creating ideal conditions – particularly during the flowering phase – for higher VPD values and healthy plant development.
