By: Brothers Equipment And Supply

Greenhouses serve as controlled environments where plants thrive under carefully managed conditions.

However, maintaining the ideal humidity level is often a challenge.

In this article, we explore the top 10 reasons why greenhouses need dehumidifiers, the consequences of neglecting humidity control, and tips on what to look for in a dehumidifier for greenhouses.

Let’s get right into it.

Top 10 Reasons Why Greenhouses Need Dehumidifiers

Prevention of Fungal Diseases: Excess humidity creates a breeding ground for fungi, including powdery mildew and botrytis. Dehumidifiers help maintain optimal humidity levels, reducing the risk of fungal diseases that can devastate crops.

Enhanced Plant Transpiration: Dehumidifiers facilitate the transpiration process, where plants release water vapor through their leaves. By regulating humidity, dehumidifiers ensure that plants can efficiently transpire, promoting healthy growth and nutrient absorption.

Improved Pollination: High humidity levels can hinder the pollination process, impacting fruit and seed development. Dehumidifiers create an environment conducive to natural pollination, essential for the reproduction of many greenhouse crops.

Consistent Crop Quality: Fluctuating humidity levels can lead to inconsistent crop quality. Dehumidifiers contribute to stable environmental conditions, resulting in uniform growth, size, and quality of produce.

Reduced Water Usage: Maintaining optimal humidity levels helps prevent excessive moisture loss from plants. This, in turn, reduces the need for additional irrigation, promoting water efficiency in greenhouse operations.

Prevention Of Mold And Mildew: Mold and mildew thrive in damp environments. Dehumidifiers play a crucial role in preventing the development of these harmful pathogens, safeguarding both the plants and the overall greenhouse environment.

Decreased Energy Costs: Dehumidifiers contribute to energy efficiency by reducing the need for excessive heating and ventilation. This not only lowers energy costs but also minimizes the environmental impact of greenhouse operations.

Extended Equipment Lifespan: High humidity can accelerate the deterioration of greenhouse equipment, including fans, motors, and structural elements. Dehumidifiers help preserve the longevity of these components, reducing maintenance costs.

Optimal Conditions for Controlled Atmosphere Greenhouses: Controlled atmosphere greenhouses, designed for precision agriculture, require specific humidity levels to maximize the effectiveness of controlled environments. Dehumidifiers play a key role in achieving and maintaining these precise conditions.

Regulation of Condensation: Excessive humidity can lead to condensation on greenhouse surfaces, posing a threat to plants and structures. Dehumidifiers mitigate condensation risks, preventing water droplets from settling on leaves and causing diseases.

Top 10 Consequences Of Greenhouses Without Dehumidifiers

Increased Disease Incidence: Without dehumidifiers, greenhouses become breeding grounds for fungal diseases, jeopardizing the health and productivity of crops.

Inefficient Plant Transpiration: Inadequate humidity control hampers the transpiration process, hindering nutrient absorption and impeding overall plant health.

Poor Pollination Rates: Fluctuating humidity levels can lead to poor pollination, affecting the quantity and quality of fruits and seeds produced.

Inconsistent Crop Quality: Uncontrolled humidity results in variable crop quality, impacting marketability and overall profitability for greenhouse operators.

Increased Water Consumption: Lack of humidity control may lead to excessive water loss from plants, necessitating additional irrigation and increasing water consumption.

Mold and Mildew Growth: Greenhouses without dehumidifiers are more susceptible to mold and mildew infestations, posing a threat to both crops and the structural integrity of the greenhouse.

Higher Energy Costs: In the absence of dehumidifiers, greenhouses may rely more on heating and ventilation systems, leading to increased energy consumption and higher operational costs.

Shortened Equipment Lifespan: Uncontrolled humidity accelerates the wear and tear of greenhouse equipment, resulting in more frequent repairs and replacements.

Challenges in Controlled Atmosphere Greenhouses: Without precise humidity regulation, controlled atmosphere greenhouses cannot achieve optimal conditions for advanced precision agriculture practices.

Condensation-Related Issues: Lack of dehumidification increases the risk of condensation, which can lead to water droplets settling on plant surfaces, promoting diseases and compromising plant health.

What To Look For In A Dehumidifier

Capacity and Coverage: One of the primary considerations when selecting a greenhouse dehumidifier is its capacity, measured in pints of water removed per day. Assess the size of your greenhouse to determine the appropriate capacity needed. Additionally, consider the coverage area the dehumidifier can effectively handle, ensuring it aligns with the dimensions of your greenhouse.

Humidity Control Range: Different crops and stages of plant growth require specific humidity levels. Look for a dehumidifier with a wide humidity control range, allowing you to tailor the settings to meet the precise needs of your plants. The ability to adjust humidity levels within a broad range enhances the versatility of the dehumidifier.

Energy Efficiency: Greenhouses often operate on tight budgets, making energy efficiency a crucial factor. Opt for dehumidifiers with Energy Star certification or high Energy Efficiency Ratios (EER) to ensure cost-effective and sustainable operation. Energy-efficient models not only reduce utility expenses but also contribute to environmentally conscious greenhouse management.

Dehumidification Technology: Different dehumidifiers employ varying technologies, including refrigeration, desiccant, or hybrid systems. Each technology has its advantages and is suitable for specific conditions. Refrigeration-based dehumidifiers are effective in warmer climates, while desiccant models excel in colder environments. Consider the prevailing climate in your greenhouse and choose a technology that aligns with your requirements.

Ease of Operation and Maintenance: Look for dehumidifiers with user-friendly controls and displays, ensuring ease of operation for greenhouse staff. Models with digital displays and programmable settings simplify the adjustment of humidity levels. Additionally, assess the maintenance requirements, such as filter replacement and cleaning, to ensure hassle-free upkeep.

Durability and Construction: Greenhouse environments can be challenging, with fluctuating temperatures and humidity levels. Select a dehumidifier constructed with durable materials that can withstand the conditions of the greenhouse. Stainless steel or corrosion-resistant components are desirable, as they contribute to the longevity of the unit.

Portability and Installation: Consider the portability of the dehumidifier, especially if you plan to move it between different greenhouse sections. Models with casters or wheels simplify transportation. Additionally, evaluate the installation process and choose a unit that aligns with the greenhouse layout and ventilation system.

Air Filtration Features: Dehumidifiers with built-in air filtration features contribute to improved air quality within the greenhouse. Look for models equipped with HEPA filters or other advanced filtration systems to capture airborne particles, allergens, and mold spores, enhancing the overall health of the plants.

Noise Level: Greenhouse workers and nearby facilities may be affected by the noise generated by dehumidifiers. Consider the noise level of the unit, especially if it will operate in proximity to human activity. Choose a dehumidifier with a noise output that aligns with the acceptable limits for your greenhouse setting.

Warranty and Customer Support: A reliable warranty and accessible customer support are essential factors in the decision-making process. Check the warranty coverage offered by the manufacturer and inquire about the availability of customer support services. A robust warranty demonstrates the manufacturer’s confidence in the product and provides assurance in case of unforeseen issues.
