CRUSH SEEDS OF SCIENCE Caveman Blend is a killer food plot mix, so easy to grow, even a caveman can do it! Nothing is more frustrating than planting a food plot that never grows. This easy-start, quick-growing blend helps those of us, who despite our good efforts, struggle to establish a usable food plot. The easy, no-till formula, gives you a ready-to-hunt green food source in as little as 2-3 weeks, making it a great late summer/early fall plant.
