Doesn't trying to view the right color drive you mad? I had a spot in the garage to look at the vial. White light, white wall, white shelf. The bulb in the bedroom is a warm light. The color of that damn vile would be different.

I HATE buying PH pens. A blue lab ph pen will last me a grow. In storage it goes bad. Unless you're adding drops of storage solution every single day.

Brother, I buy a BL ph pen before every grow. Between grows is 8-10 months. Lots of folks on here use the probe on a wire. A probe you can replace. Something I'll be going to soon. These pens are expensive but I have to know, to the point, what PH I'm running. It's a huge factor when you're chasing weight.

What is this trend to use pH meters with soil.

Most of you read someone else's wrong stuff, read a thread where they did it without mentioning pH and use that hundred dollars on an actual life problem.

Talk about selling ice to Eskimos!

If you buy a halfway decent PH pen, be sure you keep it in storage solution all the time, they are delicate little flowers.

I got lucky. I forgot to stick the cap back on my pen a week ago. The probe was without solution for about an hour. When I saw it, I freaked out. It lost its calibration. So I rinsed the probe and recalibrated. Watching the flashing zeros. Hoping like hell the probe didn't die. Waiting on that "CAL 7" and "CAL 4".

It pulled through and calibrated. Works like it did before I left the cap off.

Wholly Shit...that could have been a $100 mistake.

Really? Not the end of the world.
Just clean it properly and soak it to saturation for a couple hours, never rinse and turn on "dry".
That ruins the electrode. Sounds like you just need to store it and rinse it regularly.

Just rinsing it and keeping it wet is key. Use 4.0 calibration fluid if you don't have storage solution for PH meters. Tap water is 3rd choice, never distilled.
Use distilled water for EC meters, tap water is the second choice.
De scale it, store it in the proper solution, calibrate at 2 points...simple.
And soak it if its dry...like 2 hrs to get the crud off, but 3o minutes at least, to saturate the ceramic probe.

This is the 5th blue lab ph pen I had. Its also the only one I forgot to put the cap back on. It wasn't turned on dry. It was rinsed and stuck in solution for a few hours. Recalibrated.

As for storing and rinsing properly. No kidding.

They don't go bad in storage. It's just bad storage.
Storage is different, you actually want it dry while storing it for a while.

This one isn't being stored right.

My last one. This particular meter died. So I shot it up with some arrows. I'm in into archery. Traditional recurve. I busted this pos from 25 yards. They go bad in storage.

Nothing some duct tape and a soak in HCI cant fix, or maybe try an Apera PH60 with a replaceable probe next.:D
How are you with english long bows?
