problems with first grow any help?

This is my first log and first grow here!

Few of them problems i face right now. i'm still in the set up stage and i have to keep this room a secret so its hard for me to work on it. I am going to have 6 CFL going at once. I don't know what is better. a light cycle that is a 24/0 or something like 18/6... power bill is not a problem so id rather go 24 hours if its better. since i took so long setting up my room my plants stretched way out. im wondering if this is going to be a problem for me and maybe should i start over or is it going to work out now that i have the lights on them?

The space is rather small but im liking how everything is working out can anyone give me some suggestions that might help my grow. Should i have a fan going on these babies or would the air flow hurt them at this point? PLus when might i expect them to start filling out?

repot them and bury them deeper in the soil.
they are really stretched.

how much height do you have to work with?

18/6 nature has no 24/0
Thats a pretty big fan....

dude is part right you want to get them in to something that will help you contain the light like a box but they are not getting enough light that is why they are stretching towards the light . i cant tell from your picture but it looks like your lights are not getting enough power. if yellow tinted light is visable then you are not getting enough power to them, they should be bright white.
you want to keep the light about 2" away from your plant at all times. using those cfl will work just fine but i would try to get your light more directed towards your plant. but bury them up to around 1" from the starter leaves and get a good size fan to blow on them all the time till they grow strong stems.
GOOD luck :D
p.s. there is never enough light

and ya nature doesnt have 24/7 but your grow closet should
