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.

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.

Interview with a Cannabis Grower
“Cannabis Business Times”
..”DryGair’s knowledge and experience stem from research and operation in various kinds of crops. Now is the age in which all this is embedded into the booming field of cannabis, to create a truly efficient dehumidification solution for experienced growers wanting to put out consistent, disease-free products…”

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.
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:
- 1,500 square meter (16,000 square feet), uncooled and unheated, desert greenhouse – maintains 60-70% relative humidity using 2 DG-12 units.
- California greenhouse uses one DG-12 per 1,000 square meters – Avoids bud rot, while the untreated greenhouses experience fungal outbreaks.
- 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.

We recently spoke with WeCannect about how humidity control is changing the cannabis industry. “We spoke with DryGair’s Hadar Fuchs-Rubal to learn more about the company’s equipment, origin story, and mission to eliminate botrytis and other contagions from growing areas, as well as the changing legal status of cannabis in Israel.” Read the full
Cannabis humidity control is a major talking point among growers. In the modern era, cannabis is grown in completely controlled spaces. Greenhouses, as well as closed indoor facilities are constantly monitored and adjusted. The aim is to maintain a consistent quality of product, while attempting to maximize yields. Though humidity is a big part
Humidity, and especially the dew point, is a critical factor in cannabis cultivation. One that is much discussed but also often misunderstood. It’s time to set the facts straight. What is humidity? Air is comprised of many different gases, one of which is water vapor- the gaseous form of water. The amount of water vapor
