DWC - has anyone ever..

I have a pretty small personal garden. I'm switching over to DWC, prolly headed towards an ebb SoG. I've been reading about DWC water temps and ect, and so far using ice packs/bottles to keep the water between 15-20C.

I was wondering if anyone has ever tried freezing PH'ed water?
I'm thinking icecubes would be easy and double as a "top up" system.

Progressive experiment, or waste of time?

anyone ever tried or heard of freezin PH'd water?

No, but that sounds like a "Cool" idea.
