You’ll also need a solution for storing the pen. Do not let sensor dry out. Calibrate frequently to make certain you are getting proper readings. There are many calibration products out there. Many based on preference. This product will suit. Also you may only need one or the other. Some pens calibrate two points in which case you would get both.Ok I just got a PH meter and the directions are talking about calibrating. How do you guys and gals do this, what do you use. Thanks in advance.

I am not familiar with PH pens that require solution for storing. I am presently using the Bluelab line. What line requires solution for storing?You’ll also need a solution for storing the pen.

I was under the impression that they all did. I think it’s just the calibration solution I’m thinking of. I’ve never spent the cash on a bluelab but the ones I have had have a sponge in the cap and you’re supposed to keep that moist or wet. So the sensor doesn’t dry out. Right now I have a HM and years ago had one that said to do same thing. Don’t remember brandI am not familiar with PH pens that require solution for storing. I am presently using the Bluelab line.

That is eventually what I will have. Slowly building as I go.Personally I like and use the BlueLab triple monitor with WiFi. I like them so much i have 3 and will be buying a fourth.

My bad once again Growsince79. Coco Loco and now a blue lab pen issue. I must be the stupid farmer on here!!!!!!!!Blue lab
The good thing about this place is we all learn. I'm still tryin to figure out that cocoloco. Its tricky, and im thinking it prolongs flowering. I'm gonna compare clones loco vs promix sometime soon.My bad once again Growsince79. Coco Loco and now a blue lab pen issue. I must be the stupid farmer on here!!!!!!!!
I started my current grow with drops. After a week of veg I bought a HM meter and calibrated it. I was keeping my nutrients at roughly 5.5-5.8 with drops. When I checked it with my new calibrated meter it was reading 6.9. I recalibrated the meter to 4 instead of 7 and still pH was 6.9. I then adjusted nutrients down to 5.8 with the new meter. I’m still curious as to why the drops were so far off? The color difference between say 5.5 and 7 is a very noticeable difference. Did I contaminate solution somehow? Plants are doing great and nutrients hold steady at 5.8 with ppm of 750.I've had cheap ph pens which last a day and ive had an oakton which lasted for over a year. the issue with pens is cleaning and calibrating. mold can grow on them when they sit in solution, which requires maintenance. kind of annoying.
drops is the way to go imo. always accurate, cheap, fast, no calibrating. once you figure out your recipe you can usually mix it blind, but its still good practice to check ph every time.
Correct. Im saying the drops were reading a full point or more higher than calibrated meter reads. I’m not sure why.Drops dont need calibration
Whats the expiration date? Does it say made in China?Correct. Im saying the drops were reading a full point or more higher than calibrated meter reads. I’m not sure why.
