Yes, i forgot, don't let the pen dry up. If you use it enough, just putting the cap back on will be enough, but if you let it dry up, it will go bad.Get some pH calibration solution 7.0 and make sure the meter is correct. The electrode has to be stored wet anyway. The good ones have a small screw driver with em to set it AND DIRECTIONS. Get some perlite and dolomite for the soil too.
