GLOBAL AIR SUPPLIES 23L Intelligent Humidity Controller Dual Sonic Air Pro User Guide

SENSOR POSITIONING

The best position for the sensor is the middle of the grow room just above the canopy. Make sure that the sensor can measure the light in the room.

PLEASE NOTE: We advise you have good air circulation in your grow room, this will prevent hot spots or high humidity zones. The sensor will be more accurate if the air is moving inside the grow room, therefore, making the controller more accurate.

CAUTION
DO NOT drop or hit the sensor
KEEP AWAY from water and aerosols

CONNECTING THE CONTROLLER

Plug the controller into the SonicAir Pro using the male / male humidifier cable.

Plug your SonicAir Pro humidifier into a UK mains socket. Make sure that the humidifier is turned on.

The Dual controller is powered from the humidifier and no additional power supply is needed for the controller.

The controller will determine if it is day or night and turn the humidifier or dehumidifier on and off to control the humidity according the set point.

The power LED will illuminate when the controller is powering the humidifier. A ^ will display to show the controller is powering the dehumidifier.

Plug the controller into dehumidifier using the dehumidifier cable.

Plug the cable into the controller and the other end to the low tension external controller connector on the dehumidifier. Attach the wires as shown below & according to the labels on the wires.

If your dehumidifier has a humidistat turn this to the highest humidity setting, or off. If the dehumidifier has a internal external selector switch set it to external. Follow the instructions that came with the dehumidifier.

UNDERSTANDING VPD

The Vapour Pressure Deficit or “VPD” can be thought of as the drying power of the air.

High VPD means the air is dry, and wants to suck the water out of plants leaves. Low VPD means the air has plenty of moisture and won’t encourage water uptake through plants. VPD is a measurement of the difference of the water vapor pressure of the plant’s leaves compared with the air. The smaller the difference, or the lower the VPD, the less your plant will transpire. Transpiration is a very important aspect of plant health, the rate the plant transpires has a direct effect on the amount of water your plant draws up through its roots. Young plants don’t have many leaves or roots, so perform better in a low transpiration environment (low VPD). As the plant grows larger, with more roots and leaves, it can cope with higher transpiration rates. You can set the controller to a VPD range suitable for your plant’s growth stage, we have categorized three ranges for different stages.

Early Veg – VPD 0.4-0.8 Kpa

This is for late propagation when your plants are young. They have few leaves and a small root system, so will perform best in this setting range when transpiration is limited.

Early Flower – VPD 0.8-1.2 Kpa

When your plants are entering vigorous growth in late veg and early flower, they have more leaves and roots, so can and take up more water and nutrients with this higher transpiration setting range.

Late Flower – VPD 1.2-1.6 Kpa

When your plants have stopped vegetative growth and are maturing in the flowering stage, they have a well-established root system and leafy canopy to cope with a higher rate of transpiration. The increased water uptake is helpful at this setting range and the drier environment helps prevent pathogens.

When you have chosen a value the controller will change the humidity as the temperature changes to maintain the perfect  humidity of your plants.

VPD 24 HOURS

This is an intelligent function that takes into account the air temperature, relative humidity and plant temperature to maintain the Vapor Pressure Deficit according to the plants growth stage. Set the controller at your plants growth stage and it will calculate and maintain the ideal relative humidity.

Press the selection dial to select Vapor Pressure Deficit 24 hours.

You will then go to the sub menu to set the VPD set point you require. Turn the selection dial to the right to increase the VPD set point and turn to the left to decrease the VPD set point.

Press to save VPD set point.

You can now set the plant offset temperature. Using an infrared thermometer measure your plants leaf temperature at the canopy and note how many degrees cooler they are compared to the air temperature. This is your plant offset value. Typically, in a good grow room environment your plants leaves in direct light will be 1-3°C cooler than the air. In a grow room running too hot or too dry, the leaf temperature will be the same temperature as the air, or warmer, and in these conditions they are in serious trouble.

Turn the selection dial to the right to increase the plant offset temperature and to the left to decrease the plant offset temperature.

Press the selection dial to save and exit the menu.

VPD DAY / RELATIVE HUMIDITY NIGHT

This control type is an intelligent function that takes into account the air temperature, relative humidity and plant temperature to maintain the Vapour Pressure Deficit according to the plants growth stage. Set the controller at your plants growth stage and it will calculate and maintain the ideal relative humidity. You can also set a static night time relative humidity.

Press the selection dial to select Vapour Pressure Deficit day/ relative humidity night.

You will then go to the sub menu to set the VPD set point you require. Turn the selection dial to the right to increase the VPD set point and turn to the left to decrease the VPD set point.

Press to save VPD set point.

You can now set the night relative humidity. Turn the selection dial to the right to increase the night relative humidity and to the left to decrease the night relative humidity. Press the selection dial to save night relative humidity.

You can now set the plant offset temperature. Using an infrared thermometer measure your plants leaf temperature at the canopy and note how many degrees cooler they are compared to the air temperature. This is your plant offset value. Typically, in a good grow room environment your plants leaves in direct light will be 1-3°C cooler than the air. In a grow room running too hot or too dry, the leaf temperature will be the same temperature as the air, or warmer, and in these conditions they are in serious trouble.
