Is there a preferred site online that gives reliable info on growing homegrown hops?
This site has a lot of good information -

Go to resources (and be sure to click ‘read more’ to expand the article).
Lots of information out there. The annual hop growing threads on Northern Brewer are good 
Also, I like this manual : http://www.crannogales.com/site/manual.php
Cool workshops here: http://www.gorstvalleyhops.com/
Cheers to winter research. 8)
Jim, try Freshops…they’re in the neighborhood, so to speak.
The Vermont Extension has some great information, particularly if you live in the Northeast. Here’s a link to the hop site: http://www.uvm.edu/extension/cropsoil/hops
Also, I did an interview with the extension people who were leading a hop growing initiative in the state. The post has been the most read on my website: http://www.brewsreporter.com/hop-growing-at-home/
