Project Target
Project Goals
Stabilize temperature and humidity across all grow rooms, raise biological efficiency, reduce contamination below 3%, and cut energy cost per kilogram produced.
The Hurdles
Engineering Challenges
Parameter Drift
Load changes caused temperature and CO2 swings between rooms.
Contamination Control
Poor air handling spread spores and molds across cycles.
Energy Waste
Fixed-speed systems ran regardless of real demand.
Engineering Approach
Technical Solution
Precision HVAC + Humidification
Modular units tuned per growth stage with sensor feedback.
HEPA-filtered Air Handling
Positive-pressure rooms and staged filtration lowered contamination.
Centralized Automation
SCADA setpoints and demand-based VFD control on every room.
We moved from guesswork to data-driven growing. Stable rooms and automation transformed our consistency.
Proven Results
Project Results
Year-round output achieved with a 38% yield lift, contamination under 2%, and a 21% reduction in energy cost per kilogram.
