Ph & Ec Control
Adjusting the strength (EC) and pH of the nutrient solution to the correct levels for a particular week in your plant’s life is critical for hydroponic growing. Firstly you will need a reliable and accurate nutrient strength metre ( EC metre) and pH metre for taking readings when making and adjusting nutrient solution. Bluelab metres, Hortistick, HM digital and the pH pal, are popular with many growers. If looked after properly they are a reliable and essential piece of grow kit.
