Reflectors in my closet?

Im about to dress my closet.
Im not going to use mylar because I dont realy know where to get it in a third world country like sweden and Im kind of…..poor.
Is white paint realy better than aluminum foil? Should i use it for both the wall “and” the light reflektors?
Here is a description of a coke can reflektor: https://www.rollitup.org/view.php?pg=faq&cmd=article&id=587
But if white paint is better……??Why not paint it white?
Im thinking of building a light ramp with 2 rows of 5 CFL at a total of 10. So I can ceep the height of the room at a minimum and have the light an inch above the plants.
So, white paint inside the light ramp and walls of the closet?
Another thing, should I use any reflectors underneath the plants?

What about the reflectors inside my light ramp? Just paint there to? Maybe the aluminum reflectors direct the light better?

you can also get silver christmas garland for christmas trees, ( this is made from mylar) and fill in your plant pots with it on top of your soil and this will reflect light up ,.... those emergency camping/ survival blankets are mylar, dont you have any camping or mountianeering places where you can get this? you can also buy mylar on ebay and pay the international shipping to get it too

Im thinking of cutting out ten beer cans for reflectors above the lights in the the ramp. I tried the trick on one CFLand if you bend it at just the right angle the shine realy spreads a lot.
Painting the closet white is the way for me i think.
