Looking good man!
I always prune the first young sprouts up to about 6" tall. They taste great sauteed with some butter, salt and pepper...
My hops are starting to bloom some now. They reached the roof in mid June and have been on their way back down ever since. I need to water mine with the hose though but I've been using mulch the last couple years and it certainly helps keep the moisture right and it gives the soil some nutrients.
I gotta be honest though your set up looks and sounds awesome!
