It's rumored to help trigger the flowering hormone in the plant faster if I'm not mistaken. I have never tried it, but one of my good buddies did. Much like yours, he noticed yellowing and stretch, however his stretch looked much worse. Didn't really do much else for him. One of those things that some swear by but I haven't heard of it having a measurable result before.

On that note, we are growing a plant that is native to many environments, however, with several exceptions, there is no time a plant will be shown 24 hour light, or darkness in it's natural habitat. That being said, I typically try to stay with what mother nature has been doing, she rarely lets us down:thumbsup:
