I'm in Denver. It's been pretty hot this summer, but not as extreme as a large portion of the county. I have watered regularly all summer, so I don't think that is an issue.
I have 4 plants going, 2 Cascade and 2 Centennial, all first year. The plant of issue is one of my Centennials. It has grown very well, it just has not flowered at all and isn't showing any signs that it will. One of my Cascades got a late start, and is now just starting to flower. Probably too late, but oh well. The other two plants have produced about half an ounce each (ok I guess for first year?). The cones were of pretty good size (especially the cascade) and smelled pretty good. I brewed with them this weekend.
