`A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil. The nutrient solution and its management are the cornerstone for a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form. In soil, biological decomposition breaks down organic matter into basic nutrients that plants feed on. Water dissolves these nutrients which allows uptake by the roots. For a plant to receive a well balanced diet, everything in the soil must be in perfect balance.

Lettuces are season vegetables coming from India and cultivated for more than 2000 years ago. The bigger producers are China and the United States. Depending on the variety the leaves change of shape and colour. Two of the most popular varieties are the Roman and Iceberg. The Roman lettuce is big and erect, while the Iceberg one is round and smaller.

The PurGRO2 iLS gas transfer system is unique in its ability to create and maintain stable "controlled atmospheres" in water. This patented system and technology deliver signifi cant added value to multiple markets. In aquaculture, where oxygen is the source gas, PurGRO2 iLS creates and maintains an atmosphere in fresh and salt water of stable dissolved oxygen, at normal total gas pressures. Unlike more conventional forms of oxygenation, PurGRO2 is temperature independent, and actually delivers more oxygen with higher water temperatures.

Typically, it is not a requirement to filter a hydroponics sample.
Before use the multiple ion probe must be conditioned in Aptisens multiple ion conditioning solution. Ensure the correct calibration solutions for a three-point calibration are set up on the Mobile meter or MeterLink. Follow the instructions for calibration and proceed to take a sample reading when the calibration data is ‘very good’ or ‘good’ for all ions.
Place the probe in the aqueous extract and ‘Take a Sample’ reading. The concentrations for each ion will be displayed in ppm or mmol / L.
After taking your reading be sure to remove the sensors from the solution as quickly as possible, rinse with deionised water and replace the cap of the probe.
