I wouldn't advise not watering it for a week. You don't want to drown it, but that doesn't mean it doesn't need to be kept moist to take off. Definitely be light with the water, as in only a few tablespoons. Your seed should be planted around half an inch down, so it's not like it needs a soaking, just enough to keep the soil moist. If the soil dries out, the seedling won't dig that!
