lol scag your going to have to do something! im no pro when it comes to LST BUT im in the same situation as you. i got one sativa that is growing thourgh my roof! and i got some mandala sadhus that are nice compact indicas that i have to raise up on boxes so they dont miss out on the light. it sucks to be in that siatuation. from what ive heard i think if you lst them you will get much shorter plants.
