    Unhappy Answered: EC reading???

    Hi Peeps

    A quick question for them that know!!!

    I have just set up a Wilma system put it all together washed my clay through in the bags then put them in the pots filled the system & switched on the pump I let it run for a few hours drained the tank down refilled the tank with fresh water & let it sit for 24hours then done my PH levels got them at 6.1.

    Then I checked my EC levels just out of curiosity & I'm getting a reading of 0.4!!!!!
    How is this possible when I have not added any nutrients????

    Sorry if I'm being thick but can someone enlighten me please

    yeah the 0.4 will be your background ec..Try to keep your ec under 1.2 all the way through veg/flower,if the plants look a bit pale add a tiny amount of nutes.PH should be around 5.5 to 5.6 and drifting to around 6.2.

    The 0.4 reading is the base ec of your water.

    If I remember correctly, it has been a while since I did hydro lol, you have to take this into account when mixing your res.

    I used to let the water sit for 24 hrs, then add nutes till I got the ec I Wanted (taking into account the base reading, so if I wanted an ec of 1.4, I took it upto 1.8. 0.4 being the water only, plus the 1.4 I actually wanted), & then adjusted the ph of the res.
