Thanks for the responses guys! I have already purchased timothy grass seeds - yet to receive them. I, too envision my boys grazing is green splendor! LOL. I have not heard of the wheat grass and plan to investigate today. Knowing me, I'll end up buying those seeds too.....
I'll post photos of my project when I get things rolling. I already have a few of those clear, under bed plastic storage bins, and bags of potting soil. Of course, the potting soil bags are currently buried under snow on my driveway. LOL
