Conductivity
Conductivity according to growshops.fr
Growshops .fr presents you, through its vast online catalog, a whole range of articles to measure and control the conductivity values of a nutritive solution or a substrate.
Also called conductivity or rather electro-conductivity (EC) in the field of horticulture or aquariums, conductivity represents the capacity of materials or nutrients to let an electric current pass.
Conductivity is a unit of measurement, usually expressed in millisiemens per square centimeter(mS/cm), micro-siemens per centimeter(µS/cm) or parts per million(ppm).
In horticulture, conductivity or electro-conductivity is measured with an electronic EC tester or EC meter.
The latter allows to know the concentration of nutritive elements contained in a solution and thus to be able to follow closely, toadjust the fertilization brought to the plants, during the various stages of culture.
Find all the equipment to measure and control the conductivity or the electro-conductivity of the nutritive solution or the substrate, through its category EC PH testersyou can find all the equipment to measure and control the conductivity or electro-conductivity of the nutritive solution or substrate, through its category, at the best prices on the web on your favorite site, growshops.fr.
Thus, you will find brands with an internationally recognized reputation, such as HM Digital, BlueLab or Platinium Instruments.

Why and how should we check the EC values during an indoor plantation, according to growshops.co.uk?
During an indoor grow, in addition to following the fertilization charts indicating progressive dosages (corresponding to the naturally increasing needs of plants) and proposed by the brands of fertilizers, it is necessary to take into account that these concentrations in basic fertilizers remain to be relativized since these are established on the quality of water specific to the manufacturer, often located abroad besides, which proves to be, ultimately, completely different from that which one uses at home..

... | It is from this observation that theacquisition of a conductivity meter, an EC tester is obvious, provided that it is regularly subject to maintenance. Indeed, whatever the chosen culture medium, in potting soils or in hydroponicsit is preferable to upgrade these basic fertilizer dosages, by attesting it with an EC meter and consequently, to reach the best possible productivity of a crop. On the other hand, in order to make up eloquent measurements, the most accurate, it is important to follow a certain procedure, using the EC tester. |
The conductivity of a nutrient solution must be measured, only after diluting the additives at first.
Once the first reading by the EC meter has been taken exclusively with the dissolved stimulators, the addition of the basic fertilizers can follow, in order to compensate and thus obtain the required EC value.
The pH management only after this operation, the fertilizers will have an influence on these values (of pH).
How to maintain the electronic EC testers, according to growshops.fr?

In order to guarantee the best longevity and especially the veracity of the displayed data, the electronic EC meters require a monthly calibration. In fact, this calibration is carried out exclusively with the help of a calibration buffer solution, such as the Standard EC Solution 1.413 mS/cm and the Standard Solution 2.76 mS/cm, distributed by The Growth Technology . Because of their metal probes, the EC testers must simply be rinsed with clear water and stored in its original cap, after each end of use. |
