Dimlux Sensor Temperature Camera with VPD (for use with Maxi Controller)

The plant temperature camera that is connected and integrated to the Dimlux Maxi Controller, measures the temperature of the plant and displays the results on the Maxi Controller.

The question is:
Why do we need a plant temperature camera at all?
The reason is that it is critical for the maxi controller to understand the general stasis or health of the plant. The temperature of a healthy plant should always be less than the ambient temperature of the environment in which the plant is living in. The plant has water and nutrients constantly moving through it which keeps it cooler than the surrounding temperature. If the plant temperature rises to the same temperature as the ambient temperature, then it is no longer in a healthy state and will start to wilt and eventually die. Things that contribute to this undesirable state or environment include:

1. High intensity discharge lighting,
2. Lack of suitable extraction or ventilation,
3. Not proper water supply to the plant.

So with the aid or intelligence of the Dimlux Maxi Controller Unit the Dimlux lights that are fully controlled by the maxi controller are dimmed until the plants' temperature is less than the ambient temperature and will remain so until the fault which is causing the disproportion of plant and ambient temperature is corrected (ie. plumbing/electrical fault).

Now with the Dimlux Plant Sensor, Dimlux temperature sensor and Dimlux humidity sensor connected and integrated with the Dimlux Maxi controller, the controller is programmed to analyze the ambient temperature and plant temperature and humidity levels and calculate another measurement of vital importance which is described as the "Vapour Pressure Deficit" or VPD. This measurement is a reading which best describes the level of support of the environment in which the plant lives.

This environment is crucial for optimum growth and nutrient uptake, which revolves around how hot and humid the environment is. If the indoor environment is illuminated with HID (High Intensity Discharge) lighting and the humidity is over 70 to 80% and temperatures are in excess of 35degrees then the plants ability to photosynthesize and take in CO2 and draw or uptake nutrient is decreased and therefore the plants ability to grow and produce flowers and fruits also decreases.

So if the environment cannot be controlled or conditioned externally, then the ability of your plants to uptake nutrient and grow optimally will also be reduced, therefore to decrease illumination and heat of HID lighting is the next logical step in balancing the parameters [heat and humidity] in keeping photosynthetic reactions high, and more importantly keeping stomata in the leaves open.

By keeping the stomata open for gas exchange, which is the major force driving water and nutrients into the plant and forcing more sugars and amino acids into the flower/fruits for optimum production. Only with Dimlux Lighting and Control Gear is this level of control possible. To have greater degree of flexibility in your indoor environment regarding your lighting, the correct control gear is the key in consistently maximizing the quality and yield potential of your plants from cycle to cycle!

The idea of VPD and its application is new and exciting and for some maybe confusing. The idea (once again) is that if it’s too hot or too humid for your plants to function optimally then why waste electricity running lights at full power when the plants cannot utilize the light, when we can balance the heat and humidity by lowering the lighting power and bringing the vapor pressure deficit reading to around 1 to 1.2.

By doing this the plants will be utilizing the nutrient you are feeding them, and thereby growing and producing optimally. I repeat, this is only possible with Dimlux Lighting, Dimlux Maxi Controller and the Dimlux Plant camera and sensors. Even at 70% illumination the same yields were attained, just based on the fact that the other parameters were balanced and the optimum VPD was attained.
