Thanks all, after reading everything about 3 times I kinda get it about 39 F being the magic number where molecular change really starts hustling and, I guess, stops or shuts down around 32 F. Or, at least, everything gets lined up and peaceful at 32 F.

Boy, I don't think life started in Texas. But I kinda figure that the heavy duty immigration prior to the Battle of the Alamo and other stuff had something to do with the discovery of Tequila.

Actually, the size of West Texas water holes is a variable. Due to sparse rainfall, hot temps, low humidity and heavy evaporation, a one acre stock tank (pond) in May can become a half acre by the end of August. I get pretty narrow minded about fertilization with biomass problems under those conditions.
