There's a book on wheat grass by Steve Meyerowitz, the sproutman. In the back of
the book he has a list of wheat grass growers who ship out trays. Check it out
to see who has best price and quality. I order my wg from our local health
store, who gets it from an organic produce distributor. You might try to contact
your local health store and see if they can order it for you. I pay $16 for a
full size tray.
