Suggestions on a decent PH tester?

DCcan said:
The electrode probably needs cleaning and reconditioning, soak overnight in a hot cleaning solution, then recalibrate.
If that doesn't improve performance, replace the electrode.

Thread 'Storage, Cleaning & reconditioning pH electrodes and EC Electrodes'

Just some basics put together for keeping everyone green.
Note that Ph meters and EC meters should be stored in different liquids, and why.

Keep Your pH Electrode Hydrated:
If your electrode is dry, rehydrate the sensing tip by soaking the bulb and junction in an electrode storage solution for at least one hour, ideally overnight. Storing your electrode in storage solution also improves its life span and performance.

Storing your pH electrode in storage solution rather than water is important for reducing microbial growth, preventing the reference electrolyte from leaching...

Wouldnt surprise me if it is tired. I only use it indoor in the winter.
The storage solution was crystallized when i rinsed it off this year

It's not like the pH has to be tested daily. I test it twice a grow when I change my nute strength.

I test my PH ...2x a week an flip my rez every week. That keeps me locked into the root zone.
I feed 400 - 1600 ppms thru out the life cycle.
I check ppms every week to measure uptake.
I have seen proper PH affect ppm uptake in a major way.
Thats why i do it...

If I grew that way I'd have a pH meter as well........the best one made. But I grow in coco........and the OP never indicated how he grows.

The PH pen is quick....
Dip ...get a reading. Then PH up or down.
Dip...double check. Move on .

The liquid testers is slow...
Take a sample...drip the tester...check the color. PH up or down...take a sample...drip the tester.
Check the color
It goes on forever.
But it will get the job done

Ive spelled it out like this before lol. Except advocating for the drops. I dont feel like it right now but in short, you should be calibrating your probe. Then rinse, test. Then rinse and store with fluid and dont let it dry. Maintain the paper strip that sticks out by pulling more out as needed and if its damaged or gone so is the meter.

Need to routenely clean probe with cleaning solution. All these fluids arent cheap. You have to wait moments to get a reading where as drops are instant. I used to only complain that the color can take a while to read.

I dont have that issue anymore. Different lighting gives different results but if you keep doing it its fine. Yellow with tad orange is 5.8, yellow is 6.0. Yellow with tad green is 6.2, mostly green is 6.5 and green is beyond 6.5.

Anyway its about the same or little less effort as meter but you need new meter 50-100$ every 6 months to a year if lucky. Got to worry about manufactures changing quality or getting duds. Fragile they cant take impact.

Thats just off the top my head. Its time to get high. Peace lol.
 
Coco is not like dwc...
Its slower...
I have tried it..
I got some awesome kale like veg
Dark fiberous ultra leafy green plants.
Its just too slow for me

Dwc is streamline
