When to remove humidity dome

My seeds broke ground there maybe 36 hours ago, im using a 125w cfl on 5 auto's, im just wondering should i remove the dome and let em get direct logut or keep it on for another few days until they're a bit stronger....it's my 1st grow so i wanna be doing everything right, cheers

direct LIGHT

Do you have a humidifier? Also, since you're using cfl's, I'm not sure a humidity dome is even necessary. It's a great way to hold the humidity though (self explanatory), but if you have a humidifier (hope you do) I'd just let them get some direct light, you don't really have to worry about cfl's burning the plant, just keep an eye on the temperature. Do you have an oscillating fan?

No, I don't have a humidifier, thats why i thought the cfl with the humidity dome would be ok, have my venting up top fine and oscilating fan clipped to the side cooling the air by the seedlings, also how tall in inches should they be before i start using my 400w hps? cheers for your help
