Hey,nice thread keep us updated on how your little one is doing.Ive had stem rot in soil and was able to save a couple of them and the others kept them alive long enough to get cuttings from them.Now that your roots have dropped down into the nutrient solution you should be able to let things dry out a bit.

Ive been researching and looking at diy dwc setups for about a year and half and will probably take the plunge this winter.Great pics and the stem looks thick and healthy around your rot problem,good luck.
