Control the environment in your Greenhouse with a High Pressure Fog System
Control the environment in your greenhouse with a Fog System. Having a Fog System in your greenhouse is the best way of controlling the humidity level to provide the optimum conditions for your plants. For plant propagation ideal conditions are around 80-85% RH. For general plant production or fruit production, around 70% RH is ideal for most plants. A Fog System not only helps you with controlling the humidity level. Importantly, it also cools the air evenly across the entire greenhouse. It is the most accurate tool for humidity control in greenhouses.
Looking for a way to reduce the chance of crop diseases?
A High Pressure Fog System makes sure plants have a minimal heat and water stress environment. Reducing the stress level for plants decreases the susceptibility for diseases. Fogging changes the temperature as well as the humidity level. Immediately once the Fog System is started, the millions of microscopic water droplets start to evaporate and cool the air.In hot, dry weather, Fogging can drop the greenhouse temperature by up to 15 degrees, while raising the humidity to a much less stressful level. By avoiding wilting, the plant will be less prone to attack by fungal and bacterial infection or insects.
Increase the yield of your crop without changing the size of your production area
It is important to have conditions in your greenhouse which are ideal for your plants.This means that you should make sure that the temperature of the air is not too hot or too cold. If it is too hot in your greenhouse, the internal pump of plants shut down since they don’t want their transpiration level to be too high. Cold conditions aren’t good for plants either, because this limits their growth.
You should also make sure that the moisture rate of your greenhouse is not too wet or too dry. If it is too wet, your plants can’t transpire since the air is already saturated. Therefore the roots can’t transport as much water as they would want to the rest of the plant. If it is too dry a plant transpires too much and they run the risk of dehydration.
Every plant has a different preferred environment. Propagating plants also has a different ideal climate than maturing plants. The Fog System lets you control the climate of the greenhouse to get the ideal climate for your plants.
Looking for a way to reduce nutrient deficiencies on your plants?
It is important that your plants absorb all the nutrients they need for a good growth. If you don’t control your humidity level in your greenhouse actively, your plants may develop nutrient deficiencies. If the humidity level is too high or too low, the plant can no longer transport water and nutrients efficiently from its roots to its leaves and fruit. A Fog System allows you to influence the humidity level in the greenhouse actively and cool your plant when it is needed.
Increase the quality of your crop by regulating the air in your greenhouse.
Ensuring great quality of your plants is something that every grower wants. Great quality is largely determined by having conditions in your greenhouse which are not too hot, too cold, too dry or too wet. Every crop prefers different air conditions, so it is really important to be able to control these conditions yourself.
The Fog System is being used for changing the humidity level and cooling the air. If you want to learn more about finding the best growing conditions for your plants, take a look at the graph in our ‘read more’ section on this page regarding the Vapour Pressure Deficit. Here you will find a graph which tells you more about selecting the best air conditions for your plants. You can also contact one of our experts to help you get the right conditions for your crop.

First the water is cleaned by a 10 micron filter, then by a 5 micron filter to keep nozzle blockages to a minimum. The high pressure pump system brings it to between 800-1000psi (60-70Bar). The pure water then flows through stainless steel main lines to stainless steel lateral lines throughout the greenhouse, where it is forced out past the anti-drip valve, through the stainless steel impeller and nozzle orifice. It produces true 10 micron fog throughout the greenhouse. All parts in contact with the water are either brass or stainless steel and are locally available.
A lot of growers use two variables of the environment in their greenhouse to control the greenhouse; temperature and humidity. This would mean that they would try to get stable values for the temperature and humidity level. Controlling your greenhouse in this way is completely fine, however there is a more practical method.
More growers are starting to prefer using the ‘Vapour Pressure Deficit’-level (VPD). It is determined by the temperature and humidity level of your greenhouse. It has the same variables, but nonetheless this method has some advantages. VPD is the difference (deficit) between the amount of moisture in the air and how much moisture the air can hold when it is saturated. When the VPD is too high, plants can no longer transpire and dew of water will start to form on the leaves. If it is too low, the plant can dry out. Too low or too high VPD-levels will lower the capability of the plant to transport nutrients and will have a negative impact on growth.
The first thing this graph tells us is that plants have a different preferred humidity level for a given temperature and different preferred temperatures for a given humidity level. Therefore you don’t have to worry if your greenhouse is too hot, too cold, too dry or too wet. You just have to make sure that your plants are constantly in the ‘sweet spot’, in which the combination of temperature and humidity is ideal for plant growth. This way you longer have to control both temperature and humidity, but just have to adapt the both to one another. Since the greenhouse warms up steadily over the day due to sun hours, it makes it easier and more cost effective to adjust the humidity level to the changes in temperature.
The other advantage is that you no longer have to look at two variables. If you never used the VPD before it might take some time to get used to this method at first. The most important thing is to keep it in the sweet spot. If the VPD-level is too high, this means that you should increase the humidity level or decrease the temperature. If the VPD-level is too low, this would means that you should decrease the humidity level or increase the temperature.
