What about Barley Grass?
Barley grass can be grown, juiced, and gulped just like wheatgrass. It has similar nutritional properties as wheatgrass, just a little different. I tried growing it, but I personally couldn't stand the taste of it. It was very bitter compared to the sweet taste of wheat. My compromise is to grow a mixture of the two. I usually toss in about one spoonful of barley seeds when I am soaking my wheat seeds, and just grow them together. You will be able to see the difference in colors of the grass when it is growing, but you it won't have the bitter taste.
