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. The cubes I got with my system did not have plastic around them. I got some other ones with the plastic and had major problems with them and that is when the contamination started cause they were breaking apart. They got all yucky. The cloner I got has water running on the cubes all the time. The instructions said to let the water run all the time and when I asked the person where I got the cloner that the cubes seem to break apart, I was told to let the water run all the time and cover the cubes with the clay pebbles. Other information says that the water should run on a timer but it doesn't say how long to let the water run. So what should I do? Let the water run or put it on a timer and if it goes on a timer, how long on and how long off? I really feel stupid about this and can't seem to get it right. One thing I did learn is that the system needs to be completely cleaned and sterile all the time. Thanks for anyone's help. Bonbon and notanovice lordsoth666, heartsurgerysurvivor, garden knowm have really helped alot. Willow
