Yes the dome helps keep them in a moist environment. Just make sure to use a mist bottle when you do water so you don't accidently cover the
seeds with soil. And when you
plant the
seeds press them lightly into the soil so they don't move around as much. The first time I tried working with them I didn't do that and when they came up they were all clinging to the sides of the pots and one had actually fallen down and was
growing in the bottom of the little
green house I had it in. Rescuing it wasn't easy and it didn't survive. I don't have a delicate touch.
