Maintaining humidity in a light deprivation greenhouse involves balancing moisture levels through ventilation, irrigation management, and dehumidification. Because light deprivation requires covering the greenhouse, airflow can become restricted, which may cause humidity to rise.
To counter this, ventilation systems, such as fans and vents, are used to increase air circulation and reduce excess moisture. Proper irrigation techniques, like drip irrigation or misting, help regulate water application, preventing overwatering, which can contribute to high humidity. Additionally, dehumidifiers may be installed to actively remove moisture from the air during periods of high humidity.
