Customized HVAC
for Cannabis Cultivation
Accurate Humidity and Temperature Control
Built for Commercial Cannabis Cultivation
Prevent Pests and Mold for High Yield
Altaqua Grow Room HVAC System is an all-in-one climate control unit specifically designed for commercial cannabis cultivation, integrating dehumidification, cooling, heating, and ventilation. Compared to traditional climate control solutions, we prioritize humidity control and achieve precise temperature adjustment during the dehumidification process, creating a more stable and ideal grow room microclimate.
During the day, under high heat loads, our system performs dehumidification and cooling simultaneously to keep the grow space dry and cool. At night, when the lights are off and cooling demand decreases, plants still transpire and release moisture. The system switches to dehumidification with automatic temperature adjustment to maintain balance and prevent drastic fluctuations in temperature and humidity.
Grow Room HVAC Applications
Our Grow Room HVAC system is widely used in commercial cannabis cultivation projects with strict quality requirements, including medical and recreational cannabis. In real applications, cultivation styles vary slightly between growers, and our system can flexibly adapt and operate efficiently in all of them.
• Some growers grow cannabis from seedling to harvest in one room. Our system adjusts temperature and humidity based on each growth stage.
• Some growers divide their grow rooms based on the cannabis growth stages like veg and flower rooms. Our system can control the temperature and humidity in each room independently and precisely.
