AirGreen designs and develops solutions on a project-by-project basis, leveraging various elements of our unique design to achieve the desired temperature and humidity for each grow cycle. Our method effectively uses latent and sensible loads while complementing the company’s climate control design for optimal plant development and indoor farm efficiency.

Dehumidifiers for Grow Rooms

Precise control of temperature and humidity is critical for maximizing plant growth and development. Thus, AirGreen produces energy-efficient climate control systems for indoor agriculture operations. We also have advanced and patented technologies that handle evapotranspiration-induced humidity in plants, create optimal growth conditions, and kill mold, fungi, bacteria, and viruses.

A single AirGreen 2200  unit can remove up to 90 to 95 lbs. of moisture per hour while saving 50% to 60% on energy costs. Each unit is also custom-sized to meet the needs of specific applications.

Grow Room Temperature and Humidity Control

Indoor growing, whether large or small, requires the proper temperature and humidity levels for creating and maintaining healthier crops.

Why Is Controlling Temperature and Humidity Important?

One of the primary roles of plants is to absorb water and soak nutrients for growth. Because temperature and humidity influence how much water plants take in, controlling these thresholds allows for greater regulation of nutrient intake. Furthermore, plants use water to transport nutrients across their tissues before releasing this water as a vapor to the surrounding boundary layer air through the stomata.

The temperature of the leaves and their internal vapor pressures, as well as those exerted by the boundary layer air, drive the gas exchange. Additionally, stomatal transpiration rates increase as leaf temperatures rise at any given air temperature and relative humidity.

What Happens When Plants Get Too Hot or Too Cold?

When plants become overheated, the leaves curl and wilt while their colors may turn yellow or contain brownish or yellowish spots. The blossoms or fruits will also fall off and rot on scalded plants. On the other hand, when plants become too cold, their leaves or stems wilt, droop, or split. The root balls will also become very loose, and there will be visible burned spots on flowers and leaves.

Why Are Humidity Levels Important in Indoor Growing?

Humidity levels are critical in indoor growing because they affect transpiration and nutrient absorption. Poor levels can create a breeding ground for disease and pest infestations, while too low humidity levels might increase heat stress and damage, slow or stop plant growth, and burn the tips of the leaves. On the other hand, upper-extreme humidity levels might result in the following effects:

  • Molding and rotting
  • Developing white powdery mildew on leaves
  • Excessively dampening the leaves
  • Under developing young plants and slowing growth
  • Reducing bud size and quality
  • Increasing risk of disease outbreaks and pests

Commercial Cannabis Grow Room Dehumidification

Cannabis — also known as marijuana, weed, or hemp — is a common plant used for various purposes. It may appear simple to grow, but it necessitates complex techniques because it is at the forefront of technological horticulture.

AirGreen’s air conditioning and dehumidification systems are the ideal solutions to the high energy consumption of the cannabis growing industry. Compared to mechanical systems that over-cool before reheating to control humidity, our technology can save up to 60% on cooling season energy costs.

Control Requirements for Modern Cannabis Cultivation

Indoor farming facilities have diverse and stringent humidity, temperature, and airflow control requirements that change during the plants’ grow cycle. To address this, AirGreen offers a systematic approach to identifying the loads that indoor climate control systems must manage to design and specify solutions for efficient space conditions maintenance. This approach combines sensible and latent loads to provide design rating points for the total grow room climate control system. It also computes one value for emergent plants to determine the evaporative cooling credit and a second value for peak moisture release.

Inefficiency in Traditional Humidity Control

Indoor grow rooms frequently try to control humidity with large, inefficiently operated HVAC systems that alternate between heating and cooling to maintain optimal moisture and temperature levels. However, a more straightforward way to deal with variable sensible heat ratio is to install a set of HVAC equipment sized to handle the high sensible load during the low canopy period. During this period, traditional portable dehumidifiers are used to offset high latent loads. Although such a system can be sized, there will be times when the dehumidifier adds a sensible load that the air conditioner must remove. As a result, this combination is challenging to balance and inefficient, potentially leading to higher equipment and energy costs.

Get the Best Dehumidifying Solutions From AirGreen

AirGreen’s advanced, more efficient method is to develop a single integrated platform that modulates sensible heat ratios in response to grow room demands. When the sensible heat ratio in a grow room is high, most of the energy removed is moderate. Conversely, most energy released is latent when sensible heat ratios are low.
