I got the sample pack i ordered today from Whitetail Institute. They have a couple different packs. The one I got came with a dvd telling about their different seeds and about plots. They have a few interesting things in there. One that I liked the looks of was Imperial Extreme. Not exactly sure what it is but it suppose to grow in soil with a ph as low as 5.4. its a perrinial. I planted one of the packs in the plot that is real buleberry looking. Anyway the dvd is well worth watching for those guys thinking about or doing food plots. check them out online.
