you dont even have to soak them until they sprout.the night before you plant the seeds, soak them and plant in the morning. or when you plant them light mist untill they come up. carrot seed needs to be kept wet so they can break through the soil above them, or better put, the soil needs to be kept soft by wetting it so the carrot seeds can break through. all the plants i start indoors i sprout the seeds first. plant the most vigerous sprouts only.
