definitely get a fan blowing softly over them to sway them back and forth, to build up the stem strength. they are verrry stretched.

also if you have the fan blowing over them, you can get the CFLS very close. you need them as close as you can (an inch or two, i do even less.) with a fan blowing over the top you dont need to worry about the heat, you can touch a CFL with your bare hand thats been on for hours and hours.

Gotta get them to stop stretching before they topple over
