Hi,
I have both read and had a friend tell me that you can stick a nail in the main stem a few days before you harvest. This makes the plant think it is dying and produce crystals at an excellerated rate to protect its, in this case nonexistent, seeds. Does this work? My friend never tried it because they said it was cruel.
I've heard of this "trick". However, the problem I have with this.. is, is that the trichs on the cannabis plant.. are not developed in order to protect the plant. Trichs have nothing to do with "protection" so to say. In other words, protection of the seeds.. is not done by the plants trichromes.
The trichs on a cannabis plant (the Glandular or 'dome top' trichs) hold resin/THC up inside the dome part of the trich.. also known as the 'head' of the trich.
The purpose of these phallic wonders, believe it or not, is not euphoria in humans. Most glandular trichomes in plants serve the same purpose as other types, with some glandular hairs serving to trap insects for semi-insectivorous plants. The production of THC is probably a development for warding off larger herbivores (Ever try to get your cat stoned? Most animals aren't fans of this.) with the psychotropic effects and the distinct smell.
The only thing the nail through the stem trick is going to do.. is stress the plant out, causing the plant to speed up. However, the downside to this method.. is the fact that your going to lose a percentage of your final yield.. because of the stress on the plant itself, as well as the fact that your causing the plant to speed its processes up.
ughh.. before I write a book on this subject, I'll stop with that last statement.
A little advice.. I personally wouldn't use this method if I were you.
I would use the other method.. which is just as good if not a little better.
The other method I'm talking about, is the '48 hours of darkness" method. Which basically, all you do is.. is whenever you think your plant(s) are ready for harvesting, you basically just take your plant(s) and put them in TOTAL darkness, with no interruptions.. for 48 to 72 hours. This will also stress the plant.. causing it to push out all the resin it possibly can.. therefore raising the potency of the final product.
I have only tried this method once. I wasn't able to really see a difference.. but I could almost taste/smell a little difference in the final product.. versus one that wasn't given the '48-72 hours of darkness' before harvesting. I mean, the difference is so small and minute.. that your not going to be able to really tell that there's extra resin that was produced during the long dark cycle before harvesting.
But, each to their own.. just trying to save you some time and possibly some heartache.
peace.
