Thirty Six Hour Dark Period: A Myth With Some Truth

Recently, I heard that a 36 hour dark period could help growth and even help resin production. First thing I did when I heard this was look it up in both of the bibles. Greg Green didn't seem to mention it, that was my first clue. My second clue was when I read about it in Jorge's bible. He said there is NO real reason to do this unless you are impatient to determine plant sex. I did my own research and tried it myself in my last grow. The reason I decided to do this was curiosity and my plants were only vegging 4 weeks before I flowered. I was impatient and wanted to see the pre-flowers asap. This impatience payed off for once. I put them in the darkness period for 36 hours and out came pre-flowered plants. It was as easy as that. I had 3 males and 3 females. The perfect ratio. It was nice to be able to sex the plants early, but seemingly useless other than that. I did not see any increased resin or bud production compared to my other plants. This technique does not coincide with my paradigm, so for my current grow this strategy is out. Plus I am going to pre-flower these before I move them to flowering. I was talking to my parents about this the other day (if you don't know my dad is a botanist and my mom is a certified nursery person) they said what is happening internally is the plant thinks that it may die because for some reason the light is not coming on. If the plant thinks it will die and it hasn't entered the flowering stage, it begins flowering. The plant needs to flower in order to propagate its species. It is evolutionarily conditioned to make this so. That is why it is so imperative to remove hermies and males. They WANT to mate. So when it thinks it not going to get anymore light it makes a last ditch attempt to get laid so to speak. Its actually the same biology as hermies but you would use the 36 hour strat right before flowering, thwarting that possibility. Thanks for reading, let me know what you think.
