@Jay_Gardener, Ah, thanks for getting back at all. Those are the same brand nozzles I have, FYI they work better than the Drip Depot variety (a little large on the droplet size). Good to know about the pH perfect, the pH drift has been my biggest issue with GHE Flora series. As for the run-off, I have very little of it once good size roots are established. I made the opposite decision though, running a ~15 gal reservoir I figured it wouldn't impact it much to recirculate the small amount. I use my waste reservoir to collect dehumidifier water now, it reads <20 PPM so I use it for topping off and building nutes. Agreed on the adjustment game, just wish I could make adjustments on the fly. The Arduino has to be physically connected to my desktop to change timing-- it's a mild inconvenience.
