So what does everyone like to use for testing their ph? Im a soil or soilless mix grower and i just picked up the Oakton ph tester. I used to have the Hanna Champ but it broke and from what i hear its garbage.
I use the Oakton 10 and it works great. Make sure you calibrate it often. I didn't calibrate mine for a couple of months and found it was really off. It calibrates easy though and now I will just calibrate more often like the directions say.
I have used the dropping liquid ph. I have had bad luck with and digital meter. After you use the drops for a while you can really get to know what they like, its very cheap and pretty accurate, I use all hydro too.
I use the hanna combo meter, it's been great for over 10 yrs now. one electrode last year and a couple sets of batteries. I use it everyday. I calibrate 1x a year if that much. I clean it and store it properly.
Yes and they all must work. I have a Hanna constant ppm/ph meter but I had to send it back. They I got another hanna single ph and it broke. So I just am sticking with the drops for now. If I ever get the meters back I will give it a go again.
