Description

1. Odor Control

  • A carbon filter removes odor particles from the air before it’s exhausted outside.
  • This prevents unwanted smells from escaping your grow room.

2. Air Circulation & Ventilation

  • An inline fan helps remove stale air and bring in fresh air.
  • Good airflow prevents mold, mildew, and stagnant air pockets.
  • It ensures plants get a steady supply of CO₂ for healthy growth.

3. Temperature & Humidity Regulation

  • Grow lights generate heat, which can stress plants.
  • The inline fan pulls out hot air, keeping temperatures in check.
  • It also helps maintain ideal humidity levels to prevent mold.

4. Pest & Pathogen Prevention

  • Proper ventilation discourages pests like spider mites and fungus gnats.
  • Fresh air exchange reduces the risk of airborne diseases.

How It Works Together

  1. Inline Fan pulls air through the carbon filter.
  2. The carbon filter traps odor molecules.
  3. The filtered air is then exhausted outside the grow space.
