How do you grow cress seeds without soil and where to put it when its growing?

You can grow cress seeds without soil by using a damp paper towel or cotton pads as a growing medium. Simply spread the seeds evenly on the surface, mist them with water to keep them moist, and cover them with another damp towel or a clear lid to retain humidity. Place the setup in a bright location, such as near a window, but avoid direct sunlight to prevent overheating. Keep the paper towel or cotton pads consistently moist, and within a week, the cress will be ready to harvest.
