“Got this unit in (pretty damn quick shipping too) and realized after first use where all my problems were coming from. Cheap vivosun pens were always off, I am color blind so strips and liquids didnt work. Few days of use in coco and I am already seeing much much happier plants with the correct PH.
Thanks for the hyshield sample - plants are really liking this!!”
“Easy to use. Calibrates nicely. Waterproof (hopefully). Tip cover has spot for storage solution so it's always soaking - which reduces calibrations. But there is no darn clip built in!?? Super annoying as when I mix - I want to clip it onto my pail. I also should have bought one that had the TDS meter also built in.”
