I don't measure ppm or keep an eye on the res pH, I just pH any new bucket of feed and water that goes in. Seem to be doing OK with that! There's keeping it simple and there's being a lazy fecker, guess which category I'm in LOL!
That's quite the compliment to throw at me Ducks
thanks man! I'm still learning, this is my fourth grow with a Wilma and I love it. Mostly I just let it get on with it and throw a bucket or two in when it gets noisy because the runoff has a long way to fall i.e the res level is very low. The guys are all way more experienced with Wilma than I am!
