my supports came later on yesterday and i have noticed the change in growth in mine im gona order a ph meter i think mine is dodgy so i tryed to calibrate and dont no if i done it right i have asked a m8 to bring his down and he doesnt think his works either
Just remember a few things with pH meters.
1.They're only as good as the last successful calibration.
2.If the probe dries, it dies.
I can highly recommend 2 pH meters.
1. PH ESSENTIALS pen around £40. Good throw away pen. 1 point calibration.
2. BLUELAB PH pen around £65. 3 point calibration. 4,7 and 10. I only ever use 2 point 4 and 7 with mine.
Store pH pens in either plain water or KCI solution for longevity.
