Airflow Planning
Grow Room Ventilation Guide for LED Lighting
LED grow lights are more efficient than many traditional fixtures, but grow rooms still need ventilation to control heat, humidity and air movement around plants.
Quick Answer
Good ventilation combines air exchange and air circulation.
Exhaust or HVAC removes heat and moisture. Circulation fans move air within the canopy so leaves can transpire evenly. Both are important for healthy crops.
Ventilation should be planned with fixture wattage, room size, crop density and local climate.
Ventilation components
| Component | Purpose |
|---|---|
| Exhaust fan | Removes warm, humid air. |
| Intake or fresh air path | Replaces exhausted air with clean air. |
| Circulation fan | Reduces stagnant areas around leaves. |
| Filter | Supports air cleanliness depending on facility needs. |
| Controller | Automates fan response to temperature and humidity. |
Lighting and airflow work together
As PPFD increases, plants transpire more and the room may require stronger humidity control. Agrilumia helps customers select LED grow lights with efficient heat dissipation so ventilation systems can be sized more sensibly.
