This correlation suggests that the Moon is influencing the flow of water between different parts of the trees."
Of course, they must mean "the Moon and the Sun..." It's also interesting to note that the sun-moon tidal effect on any spot on the surface of the earth is different than on any other spot (at that point in time.)
Everyone is entitled to his own opinion, but not his own facts.
