Hydroponic Solution Reservoirs

Reservoirs are an important component of hydroponic systems where water and nutrients come together in precise quantities to be distributed to plant roots. Most hydroculture set ups like ebb and flow, nutrient film technique, aeroponic and drip irrigation systems recycle the nutritive solution to reduce waste and maximize the use of added mineral nutrients and water. The hydroponic solution is hence returned to the reservoir with a water pump where the mineral content of the water solvent is measured, via electrical conductivity, so more nutrients can be dissolved to regain the balance of set parameters. pH and temperature are also measured and adjusted in the reservoir for precision agriculture. The whole system is often completely automated through various monitoring devices and peristaltic pumps. Reservoirs used for the deep water culture hydroponic technique employ the use of an air stone or air pump to keep the water aerated and avoid oxygen poor, stagnant water. The increased amount of oxygen avalailable to the rhizosphere and uptaken by roots drives the vigorous growth of hydroponically grown plants.
