pH meters are cool. They make testing your solution easier and save time. The only problem is that they are generally quite expensive and prone to drifting readings and general failures no matter how well you maintain and calibrate them. It's gotten to the point where the only real problems I have with pH and therefore my plants, is that the pH meter decides it's no longer telling the truth and I see errors because of that. I'm tired of playing games and spending money on them just to check the counter results with drops anyway. So I just use these drops and no more problems.
