problems with 9 day old!!

I managed to germinate a seed from a stash I bought, as a bit of an experiment, it sprouted and I planted it about 8-9 days ago.
Now, It looks stretched, (Sorry no digital camera) it's approx. 4-5 inches tall and has 2 sets of leaves, the 1st pair are about an inch long and the 2nd pair about a centimetre.
It has started to lean so I'm supporting it with a small piece of coathanger, I read a message posted by notanoviceto put a drinking straw around it,(great idea mate). If i do this will the stem thicken?
I started to grow under natural light, then because of finances i used an ordinary household Energy saver bulb, I know, I know!!!! However i have ordered a Grow-Lux Tube bulb, that will arrive on Friday (today being Tuesday) Can anybody tell me will my baby survive?????
