I now have 7 plants with root rot, all a good size (1'+). I do not want to start over, but it seems that nothing gets rid of this problem. I started with more plants but then this nightmare started and I threw some out. I noticed some with root rot so I took the remaining ones and separated them and put them in their own aero box. It seems as if this didn't help because the remaining plants all have root rot now. I am not sure if they were already getting it or not, but it seems as if this problem will not go away. Does anyone know of a solution to this problem? I tried adding 29% H2O2 at 3ml/gal but that didn't seem to get rid of the problem because it soon returned. I tried adding GH's Sub-B to the res but that was ineffective. I am going to try a stronger H2O2 dip tomorrow, but am unsure if that will be very effective after reading around multiple forums. Can anyone help me out?
