Fill containers two-thirds full with potting mix.
Place several seeds in each and cover lightly with mix. Place in warm location. After germination, adjust temperatures to create day-night conditions, or gradually move temperatures back to a 65 to 70 F average. Place and keep light 2-4 inches above the top of the plants, raising the fixture as the plants grow. Apply water or a water-fertilizer solution, as needed.
