The issue of maintaining an adequate level of acidity and electrolytic conductivity of the substrate in indoor crops is a key requirement for the proper development of plants. Both too high and too low pH and EC levels of the substrate block the absorption of nutrients through plant roots. In order to control the level of electrolytic conductivity and acidity of the soil of our crops, it is necessary to periodically carry out its examination, using appropriate measures. In order for the results of such a study to be reliable, the meters should first be properly prepared by washing the electrode. In exceptional cases, the meter should be calibrated in a dedicated calibration fluid. KCl fluid is also used to store pH electrodes. The Growtent store offer includes a wide range of calibration fluids for EC and pH meters. We also sell disposable, droplet pH testers. Our offer is complemented by replaceable electrodes for meters.
