I run 50/50 chowmix in my net pots and I top drip RDWC water throughout flowering until right near the very end. I believe this contributes to plant health and vitality by providing a beneficial rhizospheric environment for both roots and bennies. Some of these beneficials get rinsed down into the RDWC water, where they maintain water quality, provide enzymes and importantly, inhibit the growth of pathogens.
As if these benefits weren't enough, running RDWC water through the net pots helps keep pH and EC more stable, reducing the need for interventions. If I didn't think it was helping so much, I wouldn't do it. Some people who think they are the be-all, end-all authorities may know their stuff within the sandbox of their own experience, but attack ideas from outside of it just because of their unfamiliarity.
I'm not one of those, and I suggest that in order to avoid falling into that trap, the reader will endeavor to gain a more full and complete understanding of just what is happening in various places within the growing environment. I didn't have a bolt from the blue epiphany about watering my net pots, I thought long and hard about the advantages of organics and soil and how I might be able to bring them to an RDWC environment.
It works for me, and I save a lot of time, money and brain damage by setting my systems up to take advantage of natural processes instead of trying to fight them. Sterility in a growing environment? In a well funded research lab, maybe- but I know for a fact that most of us are far from that well heeled.
