CO₂ Grow Room Calculator
Calculate CO₂ requirements and ventilation for indoor growing operations
Note: This calculator determines CO₂ supplementation requirements and ventilation needs for indoor growing. Always ensure proper safety measures when working with CO₂.
Formula: CO₂ Required = Room Volume × (Target CO₂ - Ambient CO₂) × Ventilation Factor
Ventilation Factor = 1 + (Ventilation Rate × 0.1)

CO₂ Management Recommendations
- Optimal Levels: 1000-1500 ppm for most crops during active growth
- Safety: Never exceed 2000 ppm - can cause health issues
- Timing: Apply CO₂ during daylight hours when plants are photosynthesizing
- Monitoring: Use CO₂ sensors and controllers for automated management
Ventilation and Safety Information
Ventilation Requirements
Minimum: 2-4 air changes per hour
Optimal: 6-8 air changes per hour
High CO₂: 10+ air changes per hour
CO₂ Safety Levels
Normal: 400-1000 ppm
Caution: 1000-2000 ppm
Danger: >2000 ppm
Temperature Effects
Low Temp: Reduced CO₂ uptake
Optimal: 70-80°F for CO₂ efficiency
High Temp: Increased respiration
Light Relationship
Low Light: Minimal CO₂ benefit
High Light: Maximum CO₂ utilization
Dark Period: No CO₂ needed
Important: CO₂ supplementation can be dangerous if not properly managed.
Always use proper ventilation, monitoring equipment, and safety protocols.
CO₂ levels above 2000 ppm can cause headaches, dizziness, and other health issues.
Ensure adequate fresh air exchange and never work in unventilated CO₂-enriched environments.
