It can be but the initial watering is more for getting them to pop. Some even use distilled water which is stripped. So your good Troon! Just keep them moist enough so the taproot is going down searching for water.
That help?
No sweat. Are you just misting or watering as well? Misting is perfect. But you need to water a little bit a well. Making sure to go easy... Don't want the seed to shift or sink deeper down...
