I have experimented growing seeds with tap water and distilled and/or rain water. The difference can be amazing. It is much more difficult for seeds to absorb tap water because of its 'hardness'. I believe this is the reason that I can water my gardens with tap water all summer with few weeds germinating. With the first rains of fall weeds are germinating everywhere!!
