Best ph pen >$200

IMO, only DWC/RDWC growers need digital PH pens or probes because of the need for constant PH measurement. Been there, things can go sideways fast.

DTW doesnt need constant PH measurement once the feed solution is prepared. PH Drops are cheap, fast, accurate, and never requires calibration.

Yeah I run DWC. Getting tired of using the drops tbh. Old habit from from my soil days; I just check the PH when I make a new batch of water+nutes and only double checked the reservoir ph when problems had already risen.

I want to stop slacking and put more effort into the dwc setup I now run and thought that a ph pen would be helpful
