Homogeneous & Consistent Climate Control with DryGair Dehumidification

The concept is simple and accommodating to cannabis’ strict requirements

bud rot, powdery mildew and alternaria are some of the most dreaded words in cannabis cultivation. destructive diseases caused by even brief periods of high relative humidity, which in a greenhouse environment, could be every night.

 

growing high quality cannabis requires tight control over conditions, from strict lighting regiments to humidity management, all in order to grow a consistent, mold free, high grade product. but controlling conditions in a greenhouse is extremely difficult. unlike indoor operations, greenhouses are susceptible to the weather outdoors. if it’s cold outside, temperatures inside will start to drop and vice versa. the same is true for any climate parameter.

humidity buildup becomes a real peril when the sun sets. screens are set up to block any light from infiltrating the greenhouse, the air outside is cold and moist, and the plants inside are transpiring. this is the reason humidity spikes, prompting water to condense on equipment, infrastructure, and plants. the most dangerous periods being dusk and dawn, when conditions change rapidly. during these periods it is very difficult, albeit crucial, to create the optimal conditions for cannabis inside the greenhouse.
the solution to greenhouse humidity management comes from drygair, a system developed at the israeli agricultural research organization – volcani. the concept is simple and accommodating to cannabis’ strict requirements. during the night, when the greenhouse is closed, drygair reduces humidity by creating dew point conditions and condensation inside the unit, instead of on the plants. dry air is then evenly dispersed 360° throughout the entire space, enabled by special, patent-protected design.
the graph below displays the relative humidity in a cannabis greenhouse, during a 6-day period. it is noticeable that during nights in which drygair was operating, relative humidity levels were not only restricted through the night, but also reliably consistent throughout the entire period.
creating consistent, homogenous, optimal conditions is the key to growing quality, disease free cannabis. with drygair as a growing tool this is now, more than ever, possible to achieve, in all growing facilities.
