Thanks Doc I was just curious what numbers were to see if it was in the same range that most soil-less growers strive for ?
Self adjusting PH is a great thing.
At the very least, Value wise, it confirms that the numbers used in the Folklure PH numbers to adjust to are basically correct
When it comes to hydro, or sterile soil industrial agriculture, pH is very important! That's not folklore.....folklore is the idea of testing runoff.
I've yet to see someone with 6 acres of corn in the ground test runoff.......but they test pH all the time.
testing runoff is the doofus thing....not testing soil pH.
