Guys sorry to jump in but your on the topic and I want to know is the benefit of using RO water worth it? Im at .4 ec tap water. Cleaner water will just be cleaner, or the plant actually grows better? Thanks in advance.
The benefit is you know whats in your water...almost nothing! I have well water. I had a great grow for my first DWC. Then something changed, I couldn't grow shit in soil or hydro. It drove me nuts for months till I finally figured out my water had changed and was killing my plants! IMO an RO unit is worth the money!
