Which type of watering system is commonly used during the propagation phase of production?

The intermittent mist system is commonly used during the propagation phase because it provides the necessary humidity and moisture levels that young plants or cuttings require for successful rooting and growth. This system helps maintain a consistent environment that promotes the healing of cuts and reduces water stress, which is critical since newly propagated plants often have limited root systems and can dry out quickly.

The key feature of the intermittent mist system is that it delivers small amounts of water at frequent intervals, ensuring that the growing medium remains moist without causing waterlogging. This system maintains optimal moisture levels, allowing for excellent air circulation while preventing fungal diseases that could arise from overly damp conditions.

Other watering systems, while effective in different contexts, do not serve propagation needs as well. Drip systems are great for established plants, providing targeted watering, but may not maintain the humidity needed for cuttings. Flooding systems can saturate the medium too much, risking root rot and other issues for new plants. Spray systems may not provide consistent moisture levels needed across a propagation bed as effectively as an intermittent mist system.
