looking for a good one. I have always used a ph probe from my reef tank which is super accurate. wondering if a ph pen might be better?

Iswear on the Bluelab Pens.Got em since 5 yrs and u barely need to Calibrate them. And they are waterproof so u can throw it in the container and mix your Nutes.
HM Digital 200 is Bullet Proof! Use the 4.01 solution for the best calibration. Best bang for your buck!

I'm quite pleased with my Hanna Combo meters. Besides measuring pH they also measure TDS and PPM. PPM comes in very handy to measure the strength of your nutrient solution and is a must have for hydro growing.
