First time growing...please help

Sup fellas.. I'm completly new to this, have had an older brother a few years back who did the same, parents used to aswel - so they don't mind me doing it.
Was hoping someone could answer a few questions of mine, and help me in any way possible. :)
I've just planted my germinated seeds yesterday, set up my wardrobe a few weeks ago but got delayed. I have 6 pots with a few seeds in each, each pot is about 6-7 inches in diameter. I've sprinkled a few balls of "plant food" over the top just incase it may help (my mum told me it won't matter anyway, since the soil I used already has enough nutrients in it. She's a horticulture nut). The light I'm using says 15w/33(might be 33, its quite faded) so is that enough? Also what kind of light is this (in pic)? I think i have to lower the light closer to the pot i've heard so i will do that if the light is actually powerful enough to grow it.
A few more questions... How long should it take the average plant/light to sprout, how long to flower, how long to harvest? There's enough room in my wardrobe to fit a 2-3 ft plant, and if i decide to grow it 5ft+ or whatever, I can easily make room. It's covered in tin-foil all over, plus the lid that covers it is also covered in tin foil...

I've probably forgotten a few questions i was gonna ask but yea, Anything ytou can answer or help me with, please do so:)

SOME PICS:

Wardrobe closed in with the lid - tin-foil covered on the inside.. tons of room at the bottom/top.

Thanks.:smoking:

::I've lowered the light to about 2-3" above the plants...

dude using tinfoil as a reflecter is a bad idea. it acts as little laserbeams that can burn holes in the plant. just white painted walls will do the trick! Everything else seems aOK

...

Yea i removed the tin-foil just yesterday, and underneath that was plain white paint so it should be alright now.My brother's also giving me a 100w fluro to use aswell + a few other fluro tubes i'll be placing vertically along with it :)wish my babies luck

i just veged a crop with a 125w envirolite {blue} heres a pic after 5 days in the light, its my 1st grow but think this is ok for the wattage got 3 plants to 10-12" in 30 days. the 1st week hung @ 10" droped it to 5" and they really picked up the pace.
