i have 3 2700k 40 w cfl's and 2 4 ft 40w 3000k tube flourescents(i know i butchered the spelling) which is more beneficial for clones/seedlings? i thought someone told me the 3 cfls in about a 1 ft wide by 1ft long by 1 1/2 ft high w/white interior and can be almost completely closed up w/just a inch or 2 open for a fan. but also i need to know which is more important, fan blowing air into grow area or is it better to have it suck the air out? i can only have 1 fan or someone will notice ...its a box fan about 2 to 3 ft wide and 2-3 ft tall it gives out pretty good wind pressure. also as soon as the clones/seedling have dropped roots i am going to be putting into 12/12 for flowering stage cuz i also do need them/it not much bigger. and also i need mother plant plant advice, advantages of other methods, thanks for reading this. (links to a reputable site are a great help, every site i went through seems to have their own opinions on all my various questions but I need answers that i havent seen yet on any websites, found any good articles? thx

Both 2700K and 3000K are WARM white, and are good for flowering. You want 5500K to 6500K COOL white for clones/ vegging.
i thought someone told me the 3 cfls in about a 1 ft wide by 1ft long by 1 1/2 ft high w/white interior and can be almost completely closed up w/just a inch or 2 open for a fan. but also i need to know which is more important, fan blowing air into grow area or is it better to have it suck the air out?
Better to use a fan to exhaust, air in can be passive. Air is like a chain...it's easier to pull it where you want it to go then to push it.
i can only have 1 fan or someone will notice ...its a box fan about 2 to 3 ft wide and 2-3 ft tall it gives out pretty good wind pressure.
A window box fan is not very enclosed, have you given ANY thought to odor controll? You should.
also as soon as the clones/seedling have dropped roots i am going to be putting into 12/12 for flowering stage cuz i also do need them/it not much bigger.
Just remember there will be a growth spurt of 2-3 times thier height, sooo if your clones are 6-8 inches tall, they could go 18 to 24". If they are sativa or sativa dominent, they could grow a long time under 12/12, all bets are off on height.
and also i need mother plant plant advice, advantages of other methods, thanks for reading this.

Not sure what mom advice you need. But if you use fluoro's get some 6000K.
