Dave I thought for sure you had that one in the bag mate. Anytime you let your air roots sit in still water they will drawn and rot. I had a feeling you werent going to get enough drainage one the pot filled with roots without proper drainage. It sucks but chalk it up to a lesson learned a vital piece of info obtained threw trial and error it sucks but now you know for next time. Hope you got that out of your system and can now move on . Knowledge is everything and tied with experience there is nothing you cant over come. Keep ur head up dave you will get there.
