Drill many holes in the bottom of the deepest cement mix tray. Fill with quality potting soil, preferable meant for veggies or heavy with nitrogen. Spread seed on soil and gently rub into soil. Water deeply and often until they germinate. Then water as the soil dries. Stick a finger in the soil. If dry up to your knuckle, WATER.
Grow in a place that gets LESS than 6 hours of sun.
This one "trough" is enough a family of two to have salads every other day.
