Condensation Monitoring in Agriculture

The inside of a greenhouse

Spring and late summer are the two seasons where humidity-related diseases peak in greenhouses.

We’ll break down the reasons why:

You see, the presence of a sunny day can boost the levels of evaporation from soil. Furthermore, it can also increase the transpiration of moisture from a leaf surface.

When the air is warm and balmy, it will hold this moisture in a vapour form. However, when nighttime arrives, the air will cool down to the dewpoint, leading to condensation.

Last but not least, water droplets will start to form on chilly surfaces, surfaces such as leaves and glazings.

What does that have to do with diseases in plants?

Well, at first glance, excess water droplets may seem harmless to plants. The issue, however, presents itself in the fact that moisture speeds up the germination of fungal pathogens on plants. Botrytis is one example of these pathogens.

In addition to this, when condensation reaches the greenhouse covering, water will drip from the covering and fall onto your plants, wetting them. Ultimately, this will spread plant pathogens across all your plants, by splashing plant debris and soil.

How can you clamp down on humidity-related diseases?

You may now be wondering, what can you do to clamp down on the spread of diseases in your plants? Well, there are multiple courses of actions you can take.

Firstly, to stop the spread of diseases, you’ll want to keep your plant canopies sufficiently dry – especially from dusk to dawn.

You can achieve this by carrying out proper watering practices. For example, take care not to water your plants too much. A general rule of thumb is to water your plants just enough to avoid spilling excess water on to the floor. Additionally, make sure to water early enough in the day to allow your plant surfaces to dry before dawn.

The alternative

Practices, such as the one mentioned above, can help you to clamp down on plant diseases, but only to a certain extent.

Above all, we recommend that you monitor the environment in your greenhouse closely.

Here at Omni, we want to make the task of environmental monitoring a little easier. We have the sensors you need to keep a closer eye on the habitat your plants live in.

We connect our smart sensors to responsive automation systems. The precise capabilities of our sensors help you to regulate factors such as the temperature, humidity and condensation within your greenhouses.

You can use the info you receive from our sensors to make the changes necessary to optimise your greenhouse environment for plant growth.
