Ugh, for years I messed around with those ridiculous pens that are unreliable, break easy and need to be calibrated often to even be in the ballpark. The strips are okay in a pinch.
This is what I use. I find it to be more practical for everyday use than anything else.
It's called a PH Test Kit. They're about $5-7 wherever you get them. They're reliable and a bottle lasts me about 6 months of everyday use. Though, now that I have my new formula dialed in, I rarely need to check the PH. The trick is to find a mix that balances to 6ish when everything is added to your particular water.

I have been using the GH pH test kit for years - it's never wrong, it's inexpensive, it doesn't need calibration, it doesn't need both 4.0 and 7.0 calibration solutions, and it doesn't need storage solution. I grow in coco so my nute solution is under 6.0, as long as the color is an orangish/yellow I'm good to go. I found that the color chart on the bottle is a bit off so I downloaded a pic of actual vials showing the true colors for 6.5,6.0,5.5, and 5.0. The pic is spot on. Obviously if you're color blind you need a pen. LOL.

Cheap pen with the ph drops to verify. I got a nice tri-meter now, but I started with the ph drops 8yrs ago and aimed for the color of piss.

If it's test strips,,,,buy medical grade.
GH fluid , well ,, not for me...
This is the best, low cost pH meter I have used...simple easy to calibrate and has the most tolerant probe I have ever seen!

GH kit it is,thanks guys. Ive been using lab grade strips but fucked up and locked boron out for a while.probably me more than the strips obviously. i ph big batches of water and nutes/water all at once so i dont really need a meter to frequently test,just something very reliably accurate,once in a while.
