ORGANISATION FOR THE ALLOCATION OF REDUCTION MEASURES TO ORGANISATIONS WITH REGULAR ENVIRONMENTAL CONDITIONS

摘要

Nutrient feed regulation systems for automatic control of nutrient flow rates in controlled environment agriculture installations utilizing nutrient film techniques. Such control is provided by feed regulators each including means defining a metering orifice of fixed flow area and means establishing a constant hydrostatic head across the metering orifice, thus enabling the maintenance of a constant nutrient flow rate to all plant growth containers in both vertically tiered and horizontally arrayed container configurations.
