I was browsing on this site and saw someone propped their baby's up with a straw. It was bent in half and held that way with a breadtie, the "v" shape layed on the top of the cup and the seedling was nestled in the middle. I couldnt believe i hadnt thought of that, great temporary setup..........props to whoever posted that pic.

No matter what you do you will find you are gonna need support unless you have super lighting really close and they get bushier than tall. Might be why LST is so effective cause they need to be "trellised" to some degree no matter what! Im still a newbie and a stoner so take everything i say with a grain of salt.
