I am currently using whole rye berry grain. It is and will continue to do the job until I run out. However, from what I am reading and watching millet & milo grain are two of the best choices. Therefore I am considering making the switch once I run out. I am leaning towards millet due to my favorite cultivator utilizing it, but I never want to make a decision of such without consulting people who have done the same test.
So, which grain do you use?
Why do you use that grain?
Any good literature on to read on this topic is always appreciated as well.
