Ryegrass is easy to grow and many of the products you listed are mostly ryegrass. I saw one at Gander Mtn that was 95% ryegrass. It's cheap and that's why they fill the bags with it. Another grass that creates a green field not a food plot. Read the label and if it has more than about 25-30% ryegrass in the product, keep looking. Last time I priced ryegrass was a few years ago and it was $.40 per pound.
