    HYDRO Your pH pen - you recalibrated it recently, right?

    Don't let your pen go too long like I did with mine. The damned thing was reading a whole point high and I was clueless why I was having problems until I questioned it this afternoon.

    "pH pen? , I don't need no stinkin pH pen!" I use pH test strips, no calibration, no batteries, and automatic temperature compensation, all for about 1 1/2 cents per test.

      Never again with a stupid PH pen...! I lost 4 Thai, 2 Jack Herer and one of my Nepal almost died !! The damn thing was totally off because of the calibration screw up, thank god I use my experience to rectify the problem. Now I'm back to the old PH meter liquid.

      I kept my old pH testing liquid just in case! I've had a cheap-ass pen that didn't last two years and gave whacked readings for the last month until it quit. I then shelled out for a better brand that also reads TDS and temperature and so far only my neglect caused any trouble with it.
