Polyhouses (or greenhouse structures) are a phenomenon in modern agriculture, providing controlled environments that protect crops from adverse weather while also enhancing the cold and warm weather seasons. But it is the management of temperature and humidity inside these structures for healthy plant growth. Foggers, misters, and cooling systems heighten this effect.

So, how do poly house accessories do it, and how does this relate to crop production in full swing? Let’s have a look and know about it in a better way.

1. Importance of Temperature and Humidity Control

Plants grown in polyhouses with the help of polyhouse accessories tend to be more sensitive to environmental fluctuations than those in open fields. Low humidity results in water loss through transpiration for plants that already stand prone to attacks by diseases and pests. It then becomes vital to create the ideal microclimate for the plants to remain healthy and productive.

2. Fogging in Polyhouses

Foggers keep sprinkling very fine droplets of water in the polyhouse and create the foggy effect, which poluhouse manufacturer have mentioned in detail. These droplets vanish in great haste after the evaporation takes place, then the latent heat of vaporization absorbs heat from the atmosphere and lowers the temperature.

Key Benefits of Foggers:

Temperature Regulation: Evaporative cooling lowers the ambient temperature by about 5 to 10 degrees Centigrade.

Humidity Management: Foggers increase the relative humidity within the structure, which is very much required for the crops such as capsicum, tomatoes, and cucumbers that prosper in humid conditions.

Disease Control: Keeping humidity at the right level away from the dangers of dry conditions will lessen the possibility of certain plant diseases.

3. Watering through Misting

Misters are close relatives of foggers, but they produce larger droplets.

Advantages of Misters:

Localized Cooling: Misters can be used in very specific areas within the polyhouse to eliminate hot spots.

Hydration: There are certain plants that would benefit from direct misting, which would provide moisture additional to that available to them through their roots.

Cost-Effective: Misters are one of the easiest systems to install and maintain and hence a favourite for small and medium-sized polyhouses.

4. Importance of Cooling Systems

According to contractors for polyhouses, while foggers and misters work well in smaller polyhouses, larger polyhouses will need bigger and more complex cooling systems such as fan-and-pad systems or evaporative cooling walls. These circumvent the passage of warm air through wet pads or mesh walls, allowing the air to cool down by evaporation around the mesh before entering the polyhouse.

Benefits of Cooling System:

Uniform Cooling: This method ensures a uniform cooling regime throughout the structure, thus avoiding temperature gradients that may cause stress to plants.

Improved Air Circulation: A fan pushes fresh air into the system, which minimizes the accumulation of pests and diseases.

5. Integration and Automation

Modern polyhouses have various polyhouse accessories that usually integrate foggers, misters, and cooling systems with automated controls that monitor temperature and humidity through sensors. As explained by the polyhouse manufacturer, these systems allow the environment to be maintained within the limits of ideal conditions for each crop, thus requiring less manual interference and whose chances of human error are minimized.

Conclusion

Foggers, misters, and cooling systems are must-haves for environments in polyhouses. With this, everyone should know that the regulation of temperature and humidity even allows growers to enhance plant health, which will result in proper reduction of disease incidence. Demand for efficient and sustainable farming is on the rise, so investing in them from a reputable poly house manufacturer like Blustal means these systems are now a necessity rather than a luxury.
