This is by far the best instructional DVD I have come across. It is hosted by Michael Bergonzi (who is literally THE industry guy to go to when it comes to growing wheatgrass).
It is sold on another site for about 20 bucks. You can find it here: http://www.shop.shopwheatgrass.com/Growing-Wheatgrass-Sunflower-Pea-Greens-and-Buckwheat-Lettuce-GWDVD.htm
Here is a little preview of the back of the DVD
So get it now and get your living greens daily!
