GHC Smart VPD Controller
The GHC Smart VPD Controller
Boost growth rates by maintaining optimal vapour pressure deficit (VPD) levels! VPD is a measure of the 'drying ability' of the air in your growroom, which dictates how quickly plants lose water. This has a knock-on effect on photosynthesis rates and nutrient uptake. The Smart VPD Controller is capable of regulating humidifiers (or dehumidifiers) and heaters in order to keep VPD in the sweet spot at all times.
- Communicates with the GHC Multi Fan Controller via a data cable
- Can also be used as a standalone
- Maintains optimal VPD levels for peak photosynthesis rates
- Regulates the switching of heaters, humidifiers or dehumidifiers
- Speeds up growth rates and increases yields
- Brings the very best characteristics from your plants' genetics

How the GHC Smart VPD Controller Works
Vapour pressure deficit is a more detailed way of thinking about the humidity levels in your grow area. It actually describes the difference in pressure between plants and the surrounding atmosphere. The higher the VPD (difference in pressure), the greater the drying ability of the air, and the quicker your plants will lose water. Maintaining optimal VPD levels keeps leaf stomata open, ensuring that your plants photosynthesise as efficiently as possible.
- If the VPD is too low, plants use very little water, which reduces their ability to uptake nutrients.
- If the VPD is too high, plants need lots of water. However, they often uptake this water while leaving behind nutrients, which can cause mineral build-ups (raised EC levels) and lead to deficiencies.
So, it's clear that VPD plays a huge role in deciding the outcome of your crop, regardless of whether you consciously pay attention to it. The GHC Smart VPD takes care of everything for you by regulating items of grow room equipment, powering up heaters, humidifiers (or dehumidifiers) whenever they're required via the sockets on the front of the unit.
