I've been working with this line for years, done the tap, done the ro, rocked the dirty, ran the HD. They all work and produce solid quality. I've got half of my shit in coco right now and the other in rockwool, everything on HD, and plants are picture perfect. My feed is .2 tap water, 5g/gal HD, recirculated, back to Rez and drop EC a few points with ro water on the next feed, back and forth, rinse repeat, done. I probably save 30% on my water and the same with the nutrient. After a while it's simple and stress free.
