Wheatgrass is just wheat. Go to your local grocery or health food store where they have bulk bins and get as much as you want.

Sow it in 3"-wide strips like grass in good soil, a week's worth in every strip, or large pots, sowing a weeks worth at a time, every week. Don't try to sow it all at once, or you will get tall, coarse, stiff stalks.

Harvest it by clipping with scissors. Easy.

Don't use chemical fertilizers.
