The best insight from that article was this part:
If you set up the adjustable trellis as described earlier, the hop vines will soon grow towards the top of the stake. When they are a few inches below the eye, untie the twine from the base of the stake and feed out a few feet of twine, letting the vine droop a bit. You may need to pull the vine gently downward to get the twine to slide through the hook and eye. Then, loosely tie the twine to the stake again.
As the vine grows, youll need to feed out more twine every time it approaches the top of the stake...
I found they are much happier constantly growing up in this fashion then if you just put them on an 8 foot pole. Since I haul my hops-in-pots to beer festivals and other talks, I actually use a pole that is retractable. Then I can get the whole thing in the back of a minivan. When I get there, it takes a few seconds to set everything back up. Even with all this abuse, I still get some hops off of these potted plants.
