PerfectpH - End to pH drifts?

Those are interesting. @SuperiorBuds is using it with success from what I understand.

This is the thread:

Recirculating Ebb & Flow

@anon32470837 and I have spoke of the Amberlite ion-exchange resins in the past, so I figured now that my res ph is stable and the plants are getting a bit bigger it was time to break out a new toy… [image] [image] I went ahead and oversized by picking up the 70 gallon unit for my 35 gallon res. I’ve only been having to give a small squirt of pH down every few days lately to keep the pH in line, so I am going to drop this in tonight and over the next few days I’ll have some solid data on h…

Also, we had looked at ion exchange resins in the buffering thread at one point as a comparison against chemical buffers:

Experimenting with the Megacrop PH and Buffering

This is related to @anon32470837 's Adventures in Hydro #2 - LP Aero/NFT mash-up - or - switching to HPA? From Larry’s experiments, there are some confounding results on how the PH is generally behaving. This has prompted me to start a series of tests to see if we can determine the buffering regions inherent in the Megacrop formula. Then, we’ll try the same with the addition of a variety of buffering formulations. These tests are ex-situ a hydro system. Thinking of the following series or som…

edit: opps, I see that you’d already linked SuperiorBuds thread. My mistake…
