Don't feel bad.... something is wrong and you will find the answer soon..

I have seen sysems that run all the time and systems that just run every 30 minutes and everything in beteen.
I have soaked rockwool for weeks (on accident) and never seen it break up. I have seen algea completey consume systems and rockwool... the plants were still GREAT...

Growing should be easier than what your going through... Can you get someone who is an experienced grower to check out your set up.... There must be something fundementaly wrong and I bet it is a quick fix...

Have you tried hydrogen peroxide?
I'd still like to see the roots : )
good luck
Garden Knowm Reviewed by Garden Knowm on . mental block about rock wool cubes are drving me crazy I took pictures and they didn't come out well enough to show anything. Thanks to notanovice for helping, at least now I know how to do it. I think that I solved my root rot problem and I think it was due to the rock wool deteriorating and contaminating my system. I follow instructions that I have gotten from all the great people who have given me advise. When I soak the cubes in 4.5 ph water for 24 hours, they seem soggy and not easy to work with when either putting in a clone or a seed. Rating: 5
