Not only does it need the right temperature and water, it needs the same amount of air as any living animal or plant. Some people in order to prevent the damp seeds, damaged, put the seeds in plastic bags to save, prefer to put some very rare seeds into plastic bags, and the mouth is very tight, like the next seed germination , See stars seedlings.
