PH & EC Control

  • pH Down pH Up

    The pH levels in all hydroponics systems need to be carefully monitored and controlled. The ideal pH range of nutrient solutions in a hydroponic set-up should be somewhere between 5.6 and 6.2. pH levels can easily be controlled with the help of either a pH up or pH down solution. If your pH levels are outside the recommended range then your system is at a high risk of causing harm to your plants. ...

  • Bluelab Guardian

    The Bluelab Guardian Monitor measures all three critical parameters to successful growth: pH, conductivity and temperature. As the environmental factors such as sunlight hours, wind, inherent plant growth change so do the plants uptake and need of water and specific nutrient elements. The Guardian is a constant indicator of the changing desired levels of pH, EC and temperature by the plant through...

  • Canna pH Down

    pH down solution for use in the early stages of plant growth - as opposed to the normal type of PH down sold for use in hydroponic systems that contain 81% phosphoric acid, this product contains 38% nitric acid. This makes it especially suitable for use with grow nutrients in very hard water areas, it will have less effect on the overall NPK of the solution when added in relatively large amounts. ...
