That's a great wheat grass set-up!  I only feed wheat grass and sprouts in the winter, when it's nothing but snow outside.  Sometimes I sprout in trays and just let the sprouts grow into grass.  Sometimes I just grow the wheat grass for the chickens in soil.  For the wheat in soil, I cut it off to feed them and then let it grow back.
I do like those baskets, though.  I have to admit, I checked out the online store, looking for those baskets, too.  I found a lot of different styles, but not that one.  Too bad.
