Hello, I am a relatively new person playing FTB. Right now I am trying to figure out how to make farms. I want to make a wheat farm and I figured out mostly how to do it. I have electrical engines getting power from solar panels that power the combine and farm. The problem I have is: How do I pipe the seeds so that it will go to the farm, but if the farm's full it will go into a chest? I know what a diamond pipe is and how to use it but when I try using a diamond pipe, it doesn't go into the farm first. I've read that it's random but how do I make it so the seeds try to go into the farm first then the chest?
