The whole purpose of starting seeds indoors is to cheat winter a little. Ironically, even as we cheat nature, we must imitate her. Light, soil, water, air, and a basic understanding of the process of germination are all you need. Once you know the simple things a seed requires, starting them indoors won t seem half as complicated.
Seeds are their own energy source, a plant in embryo form.
Until then, they remain dormant. Germination inhibitors are part of the make-up of every seed. They actually prevent a seed from germinating until its chances of survival are good. Without these, a tomato seed, for example, would spout right inside the fruit of the plant that formed it, where there is moisture and warmth, good conditions for germination. Inhibitors give a seed time to travel away from the parent plant, and allow it to overwinter, or be stored, giving that seed the best possible chance to reproduce successfully and to spread.
