Cracking the stem

I was talking to this guy and he said that you can "crack" the stem but not brake it and it will make the stem regrow bigger and stronger. Is this ture and if so what exactally do you do?

It's a true statement but don't do it unless you know what you're doing otherwise you're likely to kill your plants.

Its kind of like a muscle, you work out which tears your muscle and they repair and rebuild stronger and bigger than before, but yeah definitely don't just grab your plant and crack, you will most likely kill your plant. But if you put a fan on your plant, oscillating, it will have the same effect.

No no no no no. Any "strength in the stem" you gain would be a horrible trade off for the WEEKS you would stunt your plants growth...jus keep a fan on them. =)

Hotnsexymilfs right on.

thanks for all the help
