Three things, Pseudo:
...what light do you use for this, and why...?
...do you post things you've tried, or just things you've heard. It makes a lot of difference how you present these 'ideas' when posting in here.
...if you are so hot-n-bothered with this fantastic technique, when will we be seeing your growlog documenting the process...? (put your money where your mouth is :thumbsup: )
As I've dabbled in the technique, I know what your likely outcome will be, since my growlog terchniques (in my sig) are a direct result of chasing this technique. It doesn't work.
So, I moved on to techniques that do work.

If you are a newbie, with limited skills or if you already have problems taking a lady to maturity, this technique will likely destroy your chances of success, or at the very least, set your grow back a generation's worth of growth, troubleshooting the resultant problems. But if risking plant stunting or hermaphrodism is ok with you...go for it.
If you are a med grower, and not just 'kickin it' between recess and English As A Second Language class, I would be very leery of this technique.
