Hello everyone ... I have been through a few pH pens, and 1 or 2 actualy meters with probes, and I have always been dissapointed. I've already invested so much money into my grow that skimping on a pH meter isnt somethign I want to do. I need a pH meter that will at least give me the pH, PPM, and temperature. I'm willing to spend money, but then again i'm not on an endless budget. Does anyone have recommendations on nice, high quality pH meters t you are satisfied with?
