God Bless 'em when do they grow up?

Hey guys, I've got a couple of (Five actually) sprouts and they're showing some nice growth...I'll add pictures soon....and I'm kind of wondering when do you guys think they'll get big enough to stand on their own without support. Right now I've kind of jerry rigged some support. Any advice, or anybody else at the same point in growing that I'm at want to weigh in?
