Need good info!!!

Ok i have been looking for this post i seen the other day but can't find it or anything like it. It said something about using a blue color light or something darker like blue or something will make most of your plants females and not males. Is this true?

It isn't necessarily the color blue, but more blue as opposed to red on the spectrum. This is not scientifically proven but may carry some weight. Another non-scientifically proven method I, as well as many others, have used and had success with is the banana method. Google banana religion for any info you may need.
