Oh, I didn't mean it to be academically correct, Rick. We were on the topic of nicknames and it was meant to exemplify (as an example) of how nicknames, etc. are born. It's just a loose, undefined statement kept simple because the subect of garden chemistry is very, very complex as you know. Nonetheless, my situation was very real and I'm happy that you opened up a new thread on this very interesting topic. We can use my situation as a discussion example to start. I got a late start answering your post tonight and the dabate is coming on so I better watch it but I'll write up some background info tomarrow for open discussion.
