when a seed in its shell has germ'nd it means it has pulled in all the water it needs to break the skin and pop thru the soil. u would be better off not watering it at all then to water multiple times a day. heres a good trick ..when u plant a seed in the pot wrap the pot with clingwrap to creat the greenhouse effect, water once b4 wrapping and it wont need a water until its well and truely broken the soil.
