They're streched or "leggy" because there wasn't enough direct light power for them.
When you get your CFL you can place it quite close as they don't get too hot.
You could put it on the windowsill, but they may not get a lot of light.
You may need to get a pencil or stake and loosely tie the stem to it so it doesnt fall over as it grows. I'd also gecommend getting a fan to lightly blow it around to make the stem stronger, but dont place the fan straight at it (or it will just blow over like this)
Good luck with the grow!!
