I have 2 second year hops (cascade and willamette) growing in large rubbermaid storage containers. For a trellis I run lines to the upstairs balcony. When the hops reach the top (only about 8ft) I let out more line and hang the bines over the railing. As of tonight, both lines of Willamette have hit the top for a second time, approx 12ft in total length and there are laterals popping out all over. Last year I let it grow to more than 20ft in length but this year I was thinking of not letting any more line out and just letting it fill in. What would experienced growers recommend? Is 12ft long enough? Whats going to get me the most cones? Here is a pic of my setup from about a month ago
