I have used jap millet, seed rice and sudan sorghum mixes in past with good results in both sprout/stand. Only issue I have had was to put water on sorghum too soon and killed it off. I used 50 lb of 2 of them and hand spread over 4-5 acres with good results (intent is for crawfishing also). Deer love the sudan also-not a bad result.
Chastant sells out of Jap millet pretty quick and does not reorder. GH in kaplan may have. Hanks in Rayne was out. Happy Hunting.
