Hmm, I always assumed they were grown closer to the coast. Wonder if there is a strain that can take AZ heat? with water...Janx said:The humidity would be your problem. You'd want to look for strains that resist powdery mildew and stuff like that.
The commercial hop cultivation is mostly out in eastern Washington, which is a high altitude desert. They love the heat, but not really the humidity.
There are definitely varieties that will do well. Just look for mold/mildew resistance. freshops.com is a great resource.
