First Grow

My first grow and I have some questions. I germinated the seeds for 4 days and when they sprouted I planted them. They are kept in sunlight I have watered them twice since I planted and that was 3 days ago. How long will they take to sprout? It's getting a little chilly at night but warm during the day. Any help would be great. Check out my gallery for the pic, I couldn't get it to load for some reason.

Are they in the sun during the day??
Shouldn't be long if they have been in the sun.

Did you germinate in a paper towel or rockwool yet or just put the seeds in the soil? More info...where are you located?

Yes I germinated them in a paper towel on a plate with a bowl over it. I haven't done the Jiffy Cubes yet. I'm in Texas. They are in the sun during the day.
