As a company with expertise in both hvac systems and indoor farming, we design and integrate dehumidifying with air conditioning and more functions into one unitary unit. It offers the perfect solution to secure and control the environment throughout the cannabis life cycle, by tighter temperature and humidity control for each cannabis growing phase. It also maximizes energy efficiency while achieving the desired conditions, which lower the growers operating cost. Altaqua grow hvac system is designed and built for professional cultivation with the best quality components. It succeeds in modulating and controlling the temperature and relative humidity set points together. This helps to adjust the vapor pressure deficit to maintain ideal photosynthetic conditions for cannabis growth. It reduces energy consumption and risks of pest and pathogen contamination, which maximizes the potential of grow room. It is a complete all-in-one hvac system, which creates the perfect cannabis grow room condition by providing the following adequate control functions; *Relative humidity control *Air temperature adjustment *Vapor pressure deficit improve *CO2 enrichment control *Room pressure control *Biosecurity level maintain *Lighting stage control
