A greenhouse dehumidifier sucks excess water out of the air to maintain a consistent, healthy humidity level for plants. We rely on them to prevent mold, avoid disease, and assist crops to develop correctly. Our team at Hangzhou Ant Electrical Equipments Co., Ltd has years of experience and expertise in this industry. We assist growers in selecting the optimal size and style for their environment. In the following section, we explain how to make a good selection.

The humidity problems in greenhouses

Humidity in greenhouses is a major force that influences plant health, crop yield, and even the utility bill. We recognize that it’s not simply a number to keep an eye on, but a multidimensional challenge. Below is a table showing the most common humidity issues growers face:

Problem	Impact on Plants
High humidity	Disease, mold, mildew, weak growth
Condensation	Fungal spread, leaf burn, rot
Low humidity	Wilting, poor yield, slow growth
Fluctuating humidity	Stress, uneven growth
Poor ventilation	Stale air, more disease

Disease risk increases with humidity. Fungal issues, such as mildew and mold, propagate rapidly once air reaches the dew point. Leaf surfaces can remain wet, which allows spores to settle and thrive. This occurs the most when air can’t circulate or when watering is done late in the day. Watering before sunset allows plants minimal time to dry, which means more water clings to leaves and waters the air. It’s bad for almost any crop at any stage.

Our plants require proper humidity to breathe. When humidity is high, plant leaves can’t evaporate water vapor fast enough, so they clog up. Transpiration decreases, nutrient flow is damaged, growth declines and roots weaken. Every crop has a humidity sweet spot. For instance, tomatoes enjoy 60 to 70 percent relative humidity during fruit set. Lettuce, on the other hand, likes it a bit higher. Delicate sprouts do the dying first when air is too parched or saturated.

Humidity management is not just fan operation. Air change rates are important. If air turnover is any less than 1.2 times per hour, moisture accumulates. Heat and vent can consume 5 to 30 percent of all energy costs. Dehumidifiers consume even more power, so we have to balance each approach. ‘Grow dry’ (watering at sunrise) and intelligent venting use less energy. Below 45 degrees north, mechanical and chemical drying add less value.

Effective fixes require a complete strategy. We examine air flow, vent size, and dehumidifier sizing to maintain ideal air conditions with minimal power consumption.

Benefits after using dehumidifier in greenhouses

Dehumidifier greenhouses have real benefits for plants and for operations. We specialize in assisting greenhouse owners to create the perfect growing climate, conserve energy, and reduce costs, all while respecting the environment. Below is a quick look at the main benefits:

Benefit	How It Helps
Better Plant Growth and Crop Quality	Keeps humidity steady, avoids mold and rot, boosts yield quality.
Energy Efficiency	Modern units use less power—10 kW vs. old 80 kW setups.
Lower Operating Costs	Stops moisture damage, less waste, smarter use of water and heat.
Less Risk of Mold and Disease	Cuts the chance of mold and bud rot, protects harvest.
Stops Surface Condensation	Removes extra moisture, keeps water off ceilings and pipes.
More Reliable Than Ventilation	Pulls out 4.5 liters water per kW, works better than just opening windows.

Balanced humidity is the secret to healthy crops. Dehumidifiers can remove high humidity levels, such as 88% down to 55% relative humidity. This benefits all types of plants, but is crucial for ones such as cannabis, where optimal growth occurs between 40% to 60% humidity. When the air is too moist, mold and bud rot can destroy both quality and yield. Keeping moisture in check helps set the right temperature, which means stronger plants and better yields.

Energy is a big deal for us. New dehumidifiers are power savers, with some requiring only 10 kW instead of the 80 kW old ones use. One unit can remove up to 4.5 liters per kW, which is much more effective than vents or fans alone. Less power used means less cost and less strain on the planet.

We want to assist growers keep their greenhouses functioning smoothly, reduce risks, and maximize profits while lessening their footprint as well.

How to select right dehumidifier

To pick out the right greenhouse dehumidifier, just look at a few simple things. We want to maintain plant health, safeguard the building and consume as little energy as possible. Here’s a step-by-step way we follow to get the best fit for our needs:

First, we verify what humidity level we desire to maintain. Most greenhouses thrive at between 50% and 70%, but some plants require more or less. Newer dehumidifiers allow us to configure this from 35% to 90%. We monitor live data with a hygrometer to observe if the air is too humid or too arid. It is smart to keep a second humidity gauge, as the built-in sensor may be imperfect.
Next, we examine the two primary types of dehumidifiers. Desiccant units are good for use in cold locations, say a greenhouse in winter, even if it falls to 4°C or below (approximately 40°F). Refrigerant units perform splendidly in warm, muggy air, which typically covers the majority of the growing season. For instance, if our greenhouse gets cold in winter, we choose a desiccant. If it remains warm, refrigerant types are more economical.
We consider features. Automatic humidity control is a necessity. With Humidistat Mode, our unit powers itself on or off, maintaining the set level. For water disposal, continuous drainage is great assistance. Some units rely on gravity, so we need a drain nearby. Others have built-in pumps and can move water farther, making setup a breeze.
Power consumption is important. We look at the energy rating to be kind to your running costs and avoid wasting power. Certain dehumidifiers can extract 90 liters, which is around 198 pints, daily. We choose the perfect size so it’s never too large or small, leading to less waste and less impact on the environment.

List the sucess greenhouse cases our ANT team did

Greenhouses allowed us to grow food regardless of the time of year. They introduced the hard issue of excess humidity. Our team installed dehumidifiers in all sorts of greenhouses, from tiny cold land strawberry farms to enormous tropical vegetable plantations. Each time, we utilized units that were appropriately sized for the space and crop type. In a massive tomato greenhouse, for example, our system maintained the air at a perfectly balanced humidity, preventing water from settling on plant leaves and reducing mold. The grower reported that their crop loss due to disease decreased more than 30% and their harvest increased.

In areas with expensive power, we deployed our energy efficient dehumidifiers. These units consume 14% less power than most on the market and reduce grower’s bills. For a berry farmer in a dry zone, our low-energy system maintained the air at 45 GPP, beneath the normal range. This resulted in accelerated plant growth and reduced utilization of heating or cooling units. The farmer reported that post-installation of our system, they experienced a reduction in leaf rot cases and an obvious increase in berry production.

Our growers care about their air and want to do right by nature. We select dehumidifiers with green refrigerants, maintaining the global warming impact as low as technology permits. We provide one-stop air control units, so growers can cool and desiccate the greenhouse simultaneously. Once our units are in, humidity problems—wet floors, plant disease, etc.—fall quickly. One cucumber farm gave us data: after three months, leaf disease rates fell by half, and less water formed on glass and pipes.

Conclusion

We assist greenhouse owners in maintaining healthy, strong plants. Our crew at Hangzhou Ant Electrical Equipments Co., Ltd knows the true hassles high humidity brings. We’ve witnessed mold, weak crops, and high bills put the brakes on growers. Once we installed our dehumidifiers in a number of greenhouses, we observed rapid transformations. Plants thrive, air invigorates, and energy rates decline. We collaborate with various growers, ranging from small-scale farms to large tomato sheds. Our gang doesn’t fool around; we choose the right machine for the work. Contact us to discuss your personal greenhouse requirements. We’re here to help you breathe easy and grow better, one smart shift at a time.
