Well I would be using the R/O water strictly for True Living Organics so the chlorine/chlo-whatever doesn't kill my bacteria, fungi, nematodes, etc. Some filters get the chlorine out but I believe only R/O water gets everything out chlormine? or whatever - too lazy too google it. But I can't have either of those in my water.....
So I don't care if its slow because it'll have a float shut off and be used in a 20+gal Brute to just store water as I needed to water my soil plants. I can use the waste water in my hydro setup, yes? I don't see a downfall if I am doing both hydro and TLO/organic soil.
