I don't have a hop garden yet but I will plant soon, and am looking at some of these setups for inspiration. I dont think a 20 ft trellis is going to fly, so thinking about just going with pots for now, with a stake, and maybe run some twine from the stake to a make shift trellis, maybe 8-10 ft at best. I guess if nothing it will at least be a start, so I can get the roots going this year.
