Googleeye, it looks to me like you are stinging 5/16 tubing, is that correct? How many trees to you connect on each run? This is my second year with gravity tubing and my first doing it with good tension on the 5/16 line. I am planning on about 20 trees per line and I have about a 2% slope in the line. The ground itself is dead level as it is a red bush in wetland. Do you have any words of wisdom?
