How long does a seedling take to brake ttrough the soil?

they broke trough this morning, are they supposed to look like this when they brake through??

yup she will straiting out in a day or so and a new set of leaves will grow in fast at this point keep the light a little back until she has a few sets of leaves then you can lower it to your needs remember no nutes until 3 weeks from now and use only 1/8 to a 1/4 strength of some 10-0-0 that will get her leaves growing nicely
