stretched babies

Would tying a very loose overhand knot in the stems of a few of my stretched babies hurt or help? I have heard all kinds of weird ways that one can improve the growth of their plants, so i was just wondering.

Are they stretched out and laying down? I havent ever heard of a knot, but would be interesting to find out what happens. I had 12 stretch and i repotted up to first set of leaves on 6 of them, and other 6 i staked up. Both worked out fine. Also a fan on your seedlings will promote good healthy stem.

yeah i have done all that stuff before. I am preparing to plant outside but the light i am using to inside is too far from the sprouts. none of them are laying over though because i replanted them and used wire to stake them up.
