IN THE VALLEY THERE IS A NONSTOP BREEZE AND IT IS ALWAYS 5 OR 6 DEGREES CELCIUS COOLER THAN THE NEIGHBOURHOOD, THERE IS A GREAT DIFFERENCE BETWEEN DAY AND NIGHT TEMPERATURES. THE SURFACE LAYER IS STONY WITH PEEBLES AND SAND, FUTHER DOWN THE SOIL IS PARTLY CLAY BINDING HUMUS AND FINALLY LIMESTONE UNDERNEATH, OUR PH VALUES ARE VERY LOW.
