Grow Your Own Wheatgrass!
All ya gotta do is buy some Hard Wheat Berries (as opposed to soft wheat berries which are used for making breads and stuff), saturate them in water (soak them) for about 8 hours, as you can see by this picture, left is soaked and sprouted and right is what you buy at the store
Sprinkle your sprouted berries on some soil. Preferably not the divided things like I have, I meant to buy the solid square tray, oops.. oh well no matter.. Voila:
I learned how to do it from watching Christine Lucas and Rawesome Greens!
