"Here is the heart of the automation. It is two Z-wave strips with ten controlled outlets. Both the roll up sides and the ridge vent require two outlets each, one for the power supply and one for the DPDT relay. I will detail this a bit later if anyone is interested. The remaining outlets control water, nutrients. res agitator / aeration, exhaust fan and circulation fan. There is a secondary relay there with four DC switches. Our whole house is z-wave automation."

I’m fairly certain you’re all familiar with Allen Bradley if not directly, as a result of turning something on or off.
Cause that’s what they do, they turn shit on (1) or off (0)

I don't care if it's running on an old shoebox full of transistor radio parts and steel wool, it's running snappy! Like best I've ever experienced. Gad could have only hoped to make PG run this well.

Yep, that's open-loop control until you try to fully automate the process. Try getting a closed-loop control (where inputs directly vary outputs via algo) to run sweetly.

Generally speaking, runoff pH should be higher than nutrient solution pH. If runoff pH is lower, it indicates either a build-up of salts in the media or anaerobic bacteria, neither of which are good. In a healthy hydro system, pH always rises.
