After climate control, these are the most important and complex sub-systems in a greenhouse.
All systems must be precise and accurate in order to insure optimal nutritional conditions.
Errors in measurements and command control may cause irreversible plant damage.
Irrigation control must include EC, pH, and water drainage in accordance with light conditions.
Irrigation systems must meet specific crop requirements and be suited to soil or soil-less media.
Irrigation systems must operate accurately at low pressures and capacities.
Irrigation systems include central pump, pipes, and drip irrigation extensions.
Irrigation drips are spaced at l5-40 cm (6" l'3") intervals
