High Humidity Brings Risks

Humidity management is key when growing plants, especially marijuana. Excessive humidity can lead to serious problems such as bud rot, powdery mildew and root rot. These diseases can quickly damage or destroy plants, especially during sensitive stages such as flowering. Plants at different stages of growth, such as seedlings, vegetative and flowering, have different humidity needs, and improper humidity management can stunt plant growth, reduce yields and affect the quality of the final product.

Altaqua Grow Room Dehumidifier Competitive Advantages

Our Efficient Grow Room Dehumidifier stands out for its tailored design and high performance in grow room environments

  • Industry-Specific Design: Optimized for 27°C and 60% RH, with a high moisture removal capacity of 587 pints/day.

  • Advanced Coil Technology: Features hydrophilic-coated coils for efficient moisture transfer and corrosion resistance, enhancing durability.

  • High-Quality Filtration: Equipped with MERV-8 filter, which effectively purifies the air and is easy to operate and replace.

  • Powerful Air Circulation: Effectively evens out room temperature and avoids microclimates, creating a healthy growing environment.

  • Enhanced Performance: Utilizes four-row evaporators and condensers to guarantee both efficiency and dehumidifying capability.

How Grow Room Dehumidifier Works

Our high efficiency grow room dehumidifiers remove moisture from the humid air by means of a refrigerated evaporator coil, where the excess moisture is condensed and collected in the evaporator coil. The dry air is then reheated using a hot gas reheat coil and finally recirculated back into the room.



This process not only reduces humidity, but also maintains the optimum temperature required for plant growth, ensuring a stable and balanced grow room environment. The dehumidifier is equipped with an advanced defrost system that prevents the coils from freezing even at low temperatures, enabling it to work efficiently in different climatic conditions. Specifically designed to handle challenging humidity levels in grow rooms, the system effectively manages humidity while maintaining the perfect climate to support healthy, thriving plants, which is essential for maximising yields and ensuring crop quality.

Flexible Installation Options

Our HVAC system offers a wide range of installation options to meet different space constraints and requirements, ensuring flexibility and adaptability in any environment. We offer floor mounted installations for easy access and stability, ducted solutions for efficient air distribution and ceiling mounted installations to save floor space and keep the environment tidy and unobtrusive. A variety of installation options effectively ensure balanced temperature and humidity control, making them the preferred choice for grow rooms and greenhouses with stringent requirements for climate control.

How to Choose the Right Models

Selecting the ideal Efficient Grow Room Dehumidifier model is crucial for maintaining optimal growing conditions, as it directly impacts plant health and productivity. To ensure you make the right choice, it's essential to align your space's unique requirements with the specific features of each dehumidifier model. Here's how to make an informed decision:

01

Room Size

The capacity of the dehumidifier should match the size of the room. Therefore larger rooms may require a higher capacity model.

02

Climate Needs

Consider specific climate requirements for grow rooms, such as the humidity and temperature levels needed for different plants.

03

Energy Efficiency

Choose a model that aligns power usage with performance. Efficient units manage energy costs while ensuring effective humidity control.
