Has anyone ever used one of these testers?? I just picked one up today for 11$ and think I got ripped off! I cannot get it to read my soil ph! I haven't tried it on the other settings yet because I didn't buy it for that. Sent from my iPhone using Grasscity Forum
Well I tested the other 2 setting and they work so I went to pet store to get a water test kit and my ph is threw the roof!! Going to buy some ro water tomorrow Sent from my iPhone using Grasscity Forum
I use the same type and it seems to give a general idea of how the ph is. Maybe you got a defective one?
I've never found it to be too accurate for the pH, but I do use it to try to maximize the coverage of my light and as a moisture meter in bigger pots.
Also, make sure that you are looking at the pH scale on the bottom of the sensor. At first I thought mine wasn't moving until I noticed the numbers on the bottom.
You don't mention the type of soil. If it's manufactured I wouldn't worry about the pH, they're already adjusted for plant growth... Just make sure you pH the water you use.
If you want the most inaccurate test possible. Go to the store and get a bottle of pH tester liquid, works just fine. It should look like piss for Hydro, and slightly greener piss for soil (usually).
