Default Is gen hydro ph test accurate?

I tried a few cheaper ph meters and they only seem to work in very low ec values.
I usually adjust my ph until the gen hydro liquid turns yellow for 6.0.
I'd like to try 5.8 but it takes a very high quality meter or good strips I'm guessing.

Default ph

Hi Cbdfan !
I advise you to adjust your pH between 5.5 & 5.8 in a temperate solution. I use a ph meter Eurotech, it is a bit expensive but easy has calibrate and accurate in measurements. I think it is a vital tool.
Peace

Default No worries

I used the drops for years in the early days, thats all we had., they work well. A pH of 6 is fine the difference is marginal unless you are in rockwool.

Thanks!
I wasn't sure if yellow gives 6.0 but my cheapie ph meter so far agrees.

I use coco\perlite mix.
I usually ph yellow,6.0,but I'm trying 5.8-5.9.

The trick to keeping the cheap pH probes alive is to keep the bridge and sensor wet. Store it in pH 4 buffer and it will live a little longer.
The drops are a really good quick check if something doesn't quite add up.
You can download charts for the indicators colours if you have lost the one that comes with it.

Tap water is ok but definitely not RO water, that will kill it in a prompt manner.
A slightly acidic storage solution is best .
3mol KCl is ideal if you have it.
Cheers

I use eutech by oakton which might be the same one:
Eutech Instruments :: Products :: By Type

It seems very solid and reliable so far. Used an HM digital before that and ran into problems after about 12 months.

I personally would recommend investing a few bucks into a good PH pen you'll save yourself a lot of time and trouble.
