Battery lights?

Hey guys, new here.I'm really wanting to grow some weed for the first time but i have some problems i would like answerd by some people in the know.Heres a little backround first.
I haven't smoked weed in over a year,i moved to a new town to live with my g/f and i don't know anyone who sells it..that aside i am totaly broke anyway so i can't afford to buy it even if i knew where to get some.
So i start begging my girl to let me grow in one of the closests in the spare room,she is adament though that i'm not allowed.,so i guess i'm gonna have to do it in secret.
Now here is the thing ,i would be absolutly delighted if i could even grow enough weed for 10 joints in one grow,all i wanna have is enough to chill 2 or 3 nights of the week with a joint and enjoy the feeling of being stoned again ,which is not gonna happen unless i grow my own shit.
So i found the perfect place to grow 2 ,maybe 3 small to medium sized plants.In the closet in the spare room there is a massive cardboard box that was like for an excersise bike or something ,it's just the right size for a few small plants big enough for my purposes..heres he problem
What can i do for light in this situation ?,an extension cord running across the room into the closet is gonna give it away..i was wondering if there is any way a few small battery operated lights might do a sufficient job for my purposes ,remembering i will be happy with absolute minimum yield.Any ideas for this problem or recommended lights ,plz let me know guys ...thanks :rastasmoke:

I've seen a lot of things done, to coax a ten-foot tall plant, to fit inside a shoebox ;), but I have to tell you, you cannot grow marijuana with a battery-operated lamp ... sorry, but you can only cut so many corners ... it aint gonna happen :smokin:

lol tru dat ^^
hide the cord under the carpet??
lamo thanks
