Global Air Day & Night Controller

Keep lights-on and lights-off climate under control

The Global Air Day & Night Controller automatically switches between separate day and night settings, so a grow tent or grow room holds the right temperature or humidity through both parts of the cycle. It takes the constant manual tweaking out of running heaters, humidifiers or dehumidifiers (depending on model), keeping the climate within the ideal range for strong plant health, nutrient uptake and productive yields through veg and flowering.

Key Benefits

• Automatic day and night switching of environmental settings
• Maintains stable temperature or humidity in grow tents and grow rooms
• Compatible with heaters, humidifiers or dehumidifiers depending on model
• Updated heater controller supports up to 2kW load
• Simple, reliable operation for consistent climate control
• Supports healthier development throughout the grow cycle

Fluctuating conditions between lights-on and lights-off?

Temperature and humidity often swing as lights switch on and off, and left unmanaged that means excessive stretch, slowed vegetative growth or humidity problems through flowering. This controller adjusts connected equipment automatically for each period - stable daytime temperatures drive healthy veg growth, while controlled night-time conditions support strong structure and proper flowering development. Balanced humidity also reduces mould risk and improves transpiration, supporting root development and efficient nutrient uptake in hydro, coco and soil setups.

How to Use

• Install the controller near the equipment you want to regulate.
• Connect the device - heater, humidifier or dehumidifier - to the controller socket.
• Place the sensor probe at canopy height for accurate readings.
• Set your day and night temperature or humidity targets.
• The controller switches automatically between settings as the lights go on or off.
• Keep connected load within the 2kW maximum, and keep the controller dry - avoid water or sprays.
