CO₂ Controller – Precision Environmental Control
CO₂ Controller – Advanced Climate Precision for Cannabis Grows
Take full control of your grow room atmosphere with this high-accuracy CO₂ controller, designed for serious indoor cultivators who demand consistent environmental performance. Whether you’re running a sealed grow tent or a fully equipped flower room, this unit keeps your CO₂ levels in the ideal range to supercharge photosynthesis, boost growth rates, and maximize your yield potential.
🌿 Why CO₂ Control Matters
Cannabis thrives when CO₂ levels rise above ambient (≈400 ppm). By maintaining levels between 800–1200 ppm, plants can photosynthesise faster, grow denser flowers, and increase cannabinoid and terpene production. This controller automates enrichment, ensuring your environment stays within target range, without waste or risk of over-saturation.
⚙️ Key Features
-
Automatic CO₂ Regulation: Continuously monitors and maintains your preset CO₂ levels for precise enrichment.
-
Dark-Cycle Safety: Automatically disables dosing during lights-off periods to prevent CO₂ buildup.
-
Ventilation Override: Activates an exhaust fan when CO₂ exceeds safe limits for quick correction.
-
Plug-and-Play Setup: Easy to install and compatible with both CO₂ tanks (with solenoid regulators) and generators.
-
High-Accuracy NDIR Sensor: Provides stable, repeatable readings ideal for grow-room control.
-
Fast Response Time: Detects changes quickly to maintain consistent ppm levels around your plants.
-
Ideal for Cannabis Cultivation: Supports faster growth, stronger stems, and denser flowers in controlled environments.

🌬️ Installation Tips
-
Mount the sensor at canopy height (not directly in front of CO₂ outlets).
-
Set your target CO₂ range (typically 800–1200 ppm during lights-on).
-
Use the ventilation output to exhaust excess gas if CO₂ spikes.
-
Calibrate periodically in fresh air (~400 ppm baseline).
-
Best used in sealed or semi-sealed grow rooms where environmental control is stable.
