The cube that it was started in was only a 1" cube. It was way above the water line. My net pots were only 1.5" submerged in the solution.
I think that the root of the evil has to do with inside the net pot. Down below, you have a an oxygen rich, solution that the roots swim in. You can pretty easily control the area there. Next, you have the net pot, which is not submerged by solution, creating a moist area that might be more conducive to rot proliferation. I know at this point that to sterilize the media, that it has to all be in contact with the fungicide. So that leaves you with a balance of trying to fight the rot by dousing the whole net pot with fungicide, but then you are also trying to keep the crown and base of the stem not water logged. I know that you say you run your top feed 24hrs a day. Do you place the drippers, as to not hit the cube itself, or are you saturating the cube?
On to the future!

This is the questions I have been trying to get an answer for. These are the tweeks we need answers to. Where to place the drippers. I'm getting ready to start my first grow in the MPB and for the last week have made three different rings for my plants and really would like some clearification on wether we soak the rockwool or let it wick from the sides. If this is an answer that is only answered with experimenting so be it but many people used this system and yet still can not get an answer. DD if your around give us your two scents.
Tf i'm sorry to hear about your issues with this system and have always thought you have had one of the sickest and cleanest rooms build.
