I'm on my 5th dwc grow. I have had fairly successful grows until the last one and I got root rot despite using hydrogard. I was wondering if any of you cover your net cups to keep light out? This time I video tested for light leaks before I added water and some light was filtering thru the slits in the net cups. This time I covered them so that just a small area around stem is open but it looks like I'm starting to get RR again. Very frustrated! I used new totes, new water pumps and hose, basically everything that contacts the water or roots is new. Any thoughts?
