Home grown Hops for Homebrewed beer? - hops vine

I bought rhizomes hops from my local home store, and I'm always ready for planting. My question is, will the necessary network setup - how much do they really need to? I read that commercial growers leave the vines are 25 + feet. I can not realistically not in my garden. My idea of going to Lowes and get a 16-foot 4x4 (w / 2 feet on the ground) from the beginning was that I read about the dangers of using pressure-treated wood in the garden. Someone has a proposal for a free system that my former wife did not think it's a pain in the eye? Or is the amount of exposure to pressure-treated wood is not really a problem?
