Water, pH, EC and Irrigation
Like other factors inherent to Life, water and its management remain a crucial element in the smooth running of an indoor culture. When administered in the right proportions, water ensures the transport of plant sap and nutrients to the plants through watering Indoor Discount offers through its various sections, a complete equipment to control the watering water, dedicated to plants.
In a horticultural setting, this water control is materialized by :
- contributions in Fertilizers & stimulators,
- the hydroponic systems and the equipment related to Irrigation and drippers, available in the category Hydro cultivation,
- the pH testers and EC testers visible in Measurement & Dosing.
In short, well-controlled and adjusted irrigation water certainly contributes to a more productive and tasty crop.
What are the basic water parameters to be taken into account during indoor cultivation?
Logically, two factors come spontaneously to mind, even to the most novice gardener. These two parameters imply a daily monitoring of the nutrient solution and water, irrigated to the plants.
Firstly, the temperatures of the nutrient solution are an essential point to control in indoor cultivation. Readable with thermometers and adjustable with immersion heaters, irrigation water temperatures should be calibrated between 18°C and 20°C, as temperatures below 16°C contribute to a significant slowing down of the plant root system.
On the other hand, pathogenic moulds colonising the root zone are to be expected above 21°C. Above 24°C, it is the oxygen content of the water that becomes scarce and, in addition, harmful to root development.
On the other hand, the quality of the water used, and more precisely its purity, implies more convincing results on the quality and productivity of an indoor crop.
Made free of chlorine and heavy metals, through GrowMax Water's osmosis units and filters for example, water purified in this way leads to nutrients that are widely assimilated by plant roots, to a healthier and tastier harvest.
What instruments are needed to monitor the nutrition provided by the water?
By acquiring these two instruments, the EC tester and the pH tester, the idea is to be able to measure and quantify the EC and pH values of a nutrient solution, and thus make them grow and evolve throughout a crop. In the first instance, electroconductivity (EC) measurements are essential to the success of a horticultural experiment, especially if it is carried out on a hydroponic crop. By definition, electroconductivity represents the concentration of salts dissolved in a liquid (TDS).
Otherwise translated into horticultural language, the EC tester measures the amount of nutrients present in the irrigation water. Together with a pH tester, pH control also plays an active role in the success of a growing area. Therefore, an optimised assimilation of the nutrient solution is only achieved if certain pH values of the irrigation water are correctly adjusted and monitored.
The variations in pH values to be monitored evolve according to the substrate used and the stage of cultivation at which the plants are in.
