What Does Drip Mean?
In horticulture, 'drip' can refer to either a drip irrigation system, or a drip hydroponics system, both of which operate on similar principles and require the same basic equipment.
Drip irrigation is a method of irrigation that utilizes simple drips of water to slowly deliver moisture to a plant’s root system.
In a drip hydroponics system, there is no soil involved, and the water fed to plants includes a nutrient-rich formula that feeds plants everything they need.
Water can be dripped onto the surface of the soil/soilless grow medium, or administered directly to the plant’s root system. Using drips of water to irrigate helps cut down on evaporation that can occur with other irrigation methods.
Drip irrigation slowly moistens the soil without resulting in wasteful water runoff. Many drip irrigation systems are gravity fed and depend on the accumulation of rainwater in a rain barrel.
