Never wrong and needs no calibration.........I haven't owned a pH meter for over 20 years.

I use the GH drops too, never owned a PH meter. I used to be able to get the 8oz bottles of the GH drops but I can't find them anymore. Anyone have a source for the big bottles?Used pH meter until I got the GH drops. Never went back to the meter.
Your lucky.Hm ph-80. Been dead on for a year now
Got it up to 560, so thats better. I was probably starving them. Most likely why I had deficienciesThats it.
Two of my friends have the same meter and theirs are good tooYour lucky.
My Apera is dead on accurate as well just need store the probecorrectly in some KCI solution. Waterproof is a must.My Apera is dead nuts accurate every time. I calibrate it about once a month. If you don't want to spend the money for a good Apera or Bluelabs I would just stick to strips or drops. They aren't as precise, but they won't deceive you like the crappy cheap meters will.
$12.75 on Amazon.I use the GH drops too, never owned a PH meter. I used to be able to get the 8oz bottles of the GH drops but I can't find them anymore. Anyone have a source for the big bottles?

Those look interesting.I like these strips:
Yeah, run with that for a while, see how you goGot it up to 560, so thats better. I was probably starving them. Most likely why I had deficiencies
That's exactly why I prefer the strips. That, and the fact that I'm partially color-blind makes the drops tricky.Ever tried to use those drops to PH molasses water tho.....Not sure how the color of the solution would effect strips tho.
How comes apera has mixed reviews? It almost seems the cheap ones can sometimes be just as good. I really dont get why all these ph and tds meter have mixed reviews.I use a Sera brand PH test kit as a backup to my meter, it's far more accurate than the GH kit, though it won't last as long-glass test tube and sharper colors. The cheap PH test pens are junk, but the cheap tds meters can be accurate. I have one that's dead on and two that are 100 ppm off-but the thing is, you could probably grow a crop just fine with any of the three because they are all consistent. Bluelabs pens are great for either ph or TDS, or if you want something that works at a lesser price point, try Apera for ph and HM for TDS. My cheap tds pen that is accurate is an ispring.
