Noob looking for some help, growboxing/sprouts/water/airflow

I just got my seeds to sprout (they sprouted yesterday) and i was wondering how often do you guys water them and how? I understand to let the top get crusty but is there more to that? and how much do you water?

also the seeds are 4 white widows, just sprouted and i have one growing the fastest ( jumped about 2 inches during the day ). Since they sprouted last night, we hadn't watered them since yesterday morning (just poured a little bit in each cup) and i thought it would be a good idea to not water them until this morning. The one that was growing the fastest is no longer a straight vertical stem, it seems to have not grown as much as it did at first, and its kind of leaning to one side :-O, is this normal?

I have two t5 fluorescent lights that i bought off HTG ( very hq lights for sprouts), i have them roughly 4-6 inches away from the plants at the beginning of sprouting, could this be too close to the plants? or does that only matter when heat is a factor?

The last question is, do grow boxes need some sort of air flow in them? or is having the top open sufficient enough?

I've went through the internets and i can never find the same answers, or ones to my exact need, so any help will be much appreciated!

thanks

air circulation isa key, put a small fan blowing into the box, like a 10dollar clip on joint
