Pick up the book called "Homegrown Hops", it has some great info too. I'm in Central Ohio, and it is super easy to grow them. Certain types grow better than others though. Cascade, Nugget and Centennial do very well for me. Goldings, and N. Brewer have not yielded much the past few years.
I work with a guy who just lets them fill a flower bed, instead of growing up, and then he lets nature take care of the watering. Maybe he could get better yield but he always ends up with more than he knows what to do with. I got 3 very full grocery bags full of them last year. It was fantastic.
