World Leader in Cannabis Dehumidification

DryGair dehumidifiers, developed for cultivation experts, are the leading solution for cannabis humidity management in greenhouses and indoor grow rooms.

The patent protected design promotes climate uniformity, providing optimal growing conditions, which are the key to growing high-quality, disease-free cannabis. The DryGair solution dramatically cuts growers’ climate control and energy expenses as well as pesticide use, and contributes to larger, higher quality yields.

Video Description – Commercial Cannabis grower talks about his experience with DryGair as a growing tool. 

…“I promote the use of DryGair as a focal point in my cultivation environment designs by leveraging its dehumidification, high capacity airflow distribution, and heating & cooling capabilities…”

Conclusion:  DryGair was able to maintain the desired humidity level in the greenhouses while creating uniform climate conditions in all areas of the greenhouse, and around the plants. DryGair’s air circulation and powerful dehumidification are used as a growing tool, especially when compared to traditional humidity control methods which lead to non-uniform climate conditions. It provides the cannabis growing operation with a preventative solution for humidity diseases that is effective, economical, and green.

DryGair allows the grower to be competitive by preventing yield loss, maintaining high-quality produce, and reducing costs.

Using DryGair to control humidity eliminates bud rot development (also known as botrytis or gray mold).

Bud rot is a fungal pathogen, or mold, that develops in wet conditions, caused by humidity. High relative humidity leads to dew point condensation. When bud rot begins to develop, it produces fungal spores that spread throughout the greenhouse or grow room. Reducing humidity after bud rot has begun developing will not kill the spores already present, making outbreaks inevitable!

Controlling humidity in order to avoid the dew point prevents bud rot development before it begins. This is the only sure-fire method to eliminate bud rot.

Fast ROI compared to smaller dehumidifiers

Cover up to 4,000 m² (40,000 ft²). Stop dealing with smaller, less efficient dehumidifiers!​​

Remove More Water per kWh​​

More than 4 liters per kWh of re-useable water!​ ​

Control Both Humidity & Temperature

Alternative to extensive systems involving heating pipes and ducts. Lower maintenance costs.​​

Denser Crops and Maximized Grow Space​​​

Due to proprietary slim design and optimal homogeneous climate conditions.​​​​

"Plug & Play" Easy

A wide range of models which fit between or above the crops. No need for expensive infrastructure adjustments.

DryGair for Drying Rooms

Drying room humidity can be as high as in grow rooms or greenhouses. Harvested buds still evaporate massive amounts of water.
DryGair’s leading water extraction capacity, coupled with its unique air circulation, make it the right choice to efficiently achieve consistent, mold-free, high-quality dry flower

DryGair with HVAC: Maximum Efficiency Climate Control 

DryGair dehumidifiers are used in a wide range of greenhouses, indoor grow rooms, dry rooms, and more. In many facilities heating, ventilation, and air conditioning systems (HVAC) are also integrated to help increase climate control. However, the main function of HVAC systems is to decrease indoor temperatures, providing only a minimal secondary effect of humidity reduction.

HVAC and DryGair dehumidification humidity control

What Do DryGair Dehumidifiers Do?

  • Reduce humidity – The standard DG-12 unit removes 12 G/h (45 L/h) of water from the air (@ 64°F (18°C) / 80%RH). The unit uses only 1 kWh per 1 gallon (4 liters) of water removal
  • Prevent humidity diseases such as bud rot
  • Achieve homogenous, optimal climate conditions
  • Improve yield quality and quantity (more than 40% yield increase!)
  • Reduce energy use – savings can reach more than 50%, depending on growing facility
  • Decrease fungicide and pesticide use
  • Promote a sustainable, greener environment

These benefits lead to a fast return on investment (ROI) – 1-4 years.

The DryGair dehumidification concept is patent protected.

Examples - Growing Cannabis with DryGair

Growers use DryGair to control humidity in various climates, using different growing methods to grow a wide range of crops. These are some real examples of cannabis greenhouses that use DryGair to complete their climate control:

  1. 1,500 square meter (16,000 square feet), uncooled and unheated, desert greenhouse – maintains 60-70% relative humidity using 2 DG-12 units.
  2. California greenhouse uses one DG-12 per 1,000 square meters – Avoids bud rot, while the untreated greenhouses experience fungal outbreaks.
  3. 2,600 square meter (28,000 square feet) Oregon greenhouse – uses three DG-6 with heating and cooling as the main climate control system. During the winter, the greenhouse is maintained at a temperature 15oF warmer than outdoors, with comfortable relative humidity.

Heating & Cooling

DryGair dehumidifiers are available with additional temperature control to support and enhance active climate control.

Preventing Botrytis Without Fungicides

Botrytis, also known as gray mold or bud rot, is an extremely common humidity related disease, found in greenhouses around the world. With over 200 known species, this fungal pathogen affects most fruits and vegetables, as well as ornamentals and cannabis. Preventing botrytis is key for many different agricultural sectors. Botrytis’ Effects and Symptoms Gray
