https://www.steveshydroponics.ca Treating Powdery Mildew In The Grow Room Improving grow room conditions is an excellent way to passively prevent and minimize damage by powdery mildew. Monitor humidity levels. A quality humidity gauge should be used to monitor day and night relative humidity levels. Avoid prolonged high humidity levels: 50-60% relative humidity is ideal. Humidity must be kept below 70% during the night; levels over 80% will guarantee infection within 48 hrs. Ventilation. Constant air movement inhibits mildew, and lowers humidity. Use oscillating fans on all sides of a garden to circulate the air. Ventilate air out of the grow room periodically during the night cycle to reduce humidity from irrigation and transpiration. Once mildew is established, oscillating fans may actually spread spores throughout the garden. Stop fans, treat infected areas, and then resume airflow. Heat night air. Warm air holds more moisture than colder air. Heat helps dry the air and lower humidity during the night cycle. Heat the room at night and exhaust the room periodically to remove this warm/moist air. Dehumidifier.Very effective in preventing mildew from spreading. Set controls for 40-60% and let run during night cycle. Hepa filter. Filter the intake with a Hepa filter to eliminate spores from entering room. Inspect and change filter frequently. Ionizer or Ozone generators. Produce some output to kill airborne pathogens and spores. Sulphur burner. These devices vaporize (not burn) elemental sulphur, coat the room with a fine film of sulphur, inhibiting PM spores from germinating.
