Using a MGF misting system for greenhouse humidificationThe control of the correct level of humidity in the greenhouses is a fundamental prerogative for the yield and the growth of the crops, with the purpose to avoid dehydration of the plant.

Low humidity levels in fact brings to excessive transpiration and therefore leaves are withering and drying.

On this page we explain just why it is often necessary to increase the humidity of the greenhouse, why it's really important to do so and how MGF nebulizers make the difference in achieving this goal.

It's well known that in nature plants grow in areas where rainfall is abundant, such as the forests in temperated zones or in tropical areas. To heavy rainfall is associated with high relative humidity as a natural consequence. It 'so obvious to everyone that the plants require humidity from 70% to 90% in order to ensure that all vegetative processes are functioning properly.

In some cases, such as for the tropical plants, the optimal humidity is even higher. The same goes for crops of typical products of the underbrush, like mushrooms or berries. It's obvious that by recreating the conditions of the natural habitat in which the species have developed, will improve the well-being of the plant, the production and therefore the performance of the business.

To better understand this process, we recall some simple concepts:

The relative humidity of a greenhouse (or more generally of an environment) is the ratio between the quantity of steam (invisible) contained in the greenhouse itself and the steam that might enter in the same air up to achieve the conditions of saturation, the dew point.

When you reach the dew point, in practice, the air can not contain more additional steam and therefore water starts condensing, forming thiny droplets.

The capacity of an environment to contain steam is directly dependent by the temperature of the environment itself: higher the temperature, more it can contain steam, cooling vice versa may contain less

For this reason, when the air cools it starts raining, because the humidity contained in it is condensing and forming water droplets. For the same reason in your greenhouse, when the temperature increases, the relative humidity is lowered and this is harmful for the plants.

Through the process of transpiration, in fact, plants eliminate the waste of their metabolism through the stomata, together with water vapor, exactly like humans do with sweating. The transpiration speed depends on the relative humidity of the greenhouse, in fact, when the humidity is low, the air can absorb a lot of steam, and then the process of transpiration will be very fast, on the contrary it will be slower when the humidity is very high.

With a very quick transpiration, the leaves will wither and and then quickly dry, like it happens in the desert, where the humidity is very low. To avoid this it is not enough just to increase irrigation, but you also need to control the humidity in order to properly regulate the process of transpiration.

That's why one of the greatest risks for crops in greenhouses happens when temperatures reach around 45 °C and consequent relative humidity level falls below 35%, which is potentially lethal to crops.

 

Advantages choosing MGF humidifiers

MGF humidifiers inside a greenhouse bring several advantages:

  • Automatic system management, that is simple and economic: no human intervention, no mistakes. Our electronic controllers and pumps iControl, PC Comfort, PCI Pumps bring all advantages of the complete automation of the hudifier system.
  • Constant temperature and humidity: improved crops wellness and more productivity
  • Less power and water costs for irrigation: increasing greenhouse humidity you can reduce transpiration, therefore less irrigation is required.
  • Reduced labor costs: automatic chemicals and fertilizers diffusion through nebulizers all'around the greenhouse any time is necessary during day and night.
  • Misting nozzles dedicated to each applications: in case of humidification you can get very fine fog and therefore get higher humidification with less water.
  • Misting lines allows uniform distribution all over the greenhouse. The result is therefore better, and humidity is more constant.

MGF misting systems are designed and manufactured to meet all farmers different needs from and can be easily adapted to different contexts inside their greenhouses, from the smallest to the bigger.
