  • Hi there does the Bluelab truncheon measure PH also ?


    Unfortunately the answer is no, the truncheon is purely for measuring EC/CF. The Bluelab pH pen is sold seperately, you can find this here.

    Hope this helps 


  • Hi I just want to check I'm measuring my cf level correctly. Are you supposed to measure the cf level of your tap water, then add that to the recommended cf level on the feed chart. Or should the finished nutrient solution be what it says on the chart. Thanks

    I'd like an answer to this too, please.

  • i was led to believe that the truncheon was an all in one reader but does not mention ph is a ph reader needed as most tap water is neutreul

    The Bluelab cF truncheon will measure the amount of nutrient in the solution, you also need to check the pH & adjust if required. Optimum pH for your nutrient solution is 6.2, but it is fine between 5.8 -6.8

  • when your ready to harvest and your flushing what should the reading be? and if i take a reading when im growing how will i know om giving it the correct amount of feed is there a chart or something telling you does it give you the reading on the truncheon?

    The cF whilst flushing should be the same as your tap water, typically 2 in soft water areas, 8 in hard water areas. During the Growth cycle you can always refer to the chart in the back of our catalogue, but remember to check against your level of water hardness.
