Help the New(b)

I got lots of seeds from random people i know.and ive planted about 6 of dem suckers and 3 have really taken off. But with this bein my first time growing i didnt want to go all out with equipment and waste...just in case i sucked at it. But anyways i got three plants about 5 inches tall, but it looks like there gettin kinda weak in the stem. i had to support them with tooth picks. Im using a light that is supposed to emitt lots of uv rays.. which im considering to be part of the problem ....Is it or not?.. Does Home depot sell anything worth while. Plz reaspond asap........

 

i was usin this uv light i found layin around the house. and i did have a fan on them.. plants are about 2 1/2 weeks old.. but i think im about to abondon that little experiment and start off fresh with the rright materials. By the way if i were to go to home depot what light should i buy to support 2 plants. I really dont want to go on the internet. and since its my first time i really want to go with some cheap lights.. plz help what wattage and things should i bee lookin for???

 

ok im pretty sure i can get those 100-250 watt security bulbs so with that in mind im very thankful for that information ndicabud.... bout how many of those do i need to( if i can) comfortably grow 2 females in a closet space that is 5 1/2" tall, around 1" in depth and is 4 3/4" in width. If it helps any i can squeeze a few inches here and there and get the height to about 2 more feet... also im not too sure what you mean by hps. is it a characteristic that i should be looking for in all my bulbs and fixtures.... Home depot also sold the special plant bulbs that were around 165-200 watts but they werent flourecent, and ive been told that flourencent is better......what you think i should doo?????
