he is talking about stretching the plants to increase yeild though not for lst or cutting(which both make great sense)and that is why i said that he shouldn't.all he will end up with is the same weight and airy buds.(if stretching would increase yeild then why does everyone try to get the closest nodes possible?)
first off, there is nothing wrong with 'airy' buds, if anything they are better than dense buds as air circulation is improved, however, stretching alone will not increase yeild, when a plant stretches for light, it puts all its growth into the stem, in which case the buds will slow growth, basically decreasing yeild slightly, unless you are going to use the stretched section of the stem for LST its not really worth doing, especially if your plant is already flowering, it wont want to grow upwards. if you want my opinion, dont bother stretching, just keep in mind that this method can be used in your next grow, where you can stretch during vegging and use the stretched section to help tie it down. I hope this helped, and im glad you are showing an interest intrying to increse yeild, after all, its gotta be worth looking into.... good luck m8!
