BEGINNER'S GUIDE TO FOGGING IN YOUR GREENHOUSE

In simple terms, fogging is a visible cloud of water droplets suspended in the air. Growers use a fogging system to regulate humidity and create an ideal setting for plants to grow.

Why is fogging important?

As humans we strive in an environment we feel comfortable in and, when uncomfortable, we tend to struggle. The same goes for plants. It is crucial to create an environment that is ideal for whatever plant you’re trying to grow. When the humidity levels are low, photosynthesis which is the process used by plants to harness energy from sunlight into chemical energy is slowed or even stopped. Stressful environments are preventable by creating a setting where plants can exchange moisture, oxygen and carbon dioxide.

Plants flourish with the right level of humidity because their pores are entirely open and when this happens, plants breathe deeply, and there is no threat of excessive water loss.

Fogging systems have been proven to be beneficial to baby plants, micro plants and vegetative plants as they prefer exposure to humidity.


How can a high-pressure fogging system help you?

The system is an immediate fix and will affect the humidity levels straight away. For the air to cool, the fogging system immediately releases microscopic droplets that are small enough to stay suspended in the air while heat from the air is being evaporated and extracted. This technique can reduce the greenhouse temperature by an estimated 15 degrees Celsius (59 degrees Fahrenheit) while raising the humidity. The system helps create healthy plants, reduces the risk of fungal, wilting and insects.


Will the high-pressure fogging systems fit your greenhouse?

Most fogging systems are designed to fit most greenhouse structures. Fog nozzles are spaced evenly above plants throughout the greenhouse. The fog then assists the greenhouse by exchanging the outside air that has entered through the side-wall ventilators.

 

How can you take full advantage of your high-pressure fogging system?

The high-pressure fogging system can be paired with two separate tools so that you can create the ideal environment. The options are to use a misting system or energy curtains.

Misting systems will help you increase and control the humidity, so your plants will receive the moisture it needs. The system has proved to produce favorable and consistent conditions throughout the year. You can prevent disasters such as over-heating the greenhouse; however, an issue you may have is large droplets falling and damaging your crops. Fluctuating humidity and temperature levels can result in damaged plants. When the relative humidity levels drop below 30% plants can stop growing.

The design of the misting system includes nozzles that are attached to the ceiling or structure of the greenhouse with a tube which is pressurized to release a subtle spray over your crop. The system minimizes plant stress and increases germination and growth rates.

Another option you can check out is energy curtains; this will help you trap the humidity.

 

What is the downside of using a fogging system?

You should consider the issue with clogged nozzles from particulate and chemical matter. Particles of clay and sand can clog the fog nozzles.


What are the benefits of the fogging system?

A fogging system can help you:

  • reduce your energy consumption

  • cost-effective

  • helps maintain an environment suitable for your crops

  • prevents a slow growth rate caused by unfavorable climate conditions

  • reduces water consumption and at the end, you have an excellent crop quality.

Remember, not all plants need to be fogged.  It all depends on the crop and your environment.
