Hey Growmie! Yes, this is a really cool trick, especially if you want to save a killer genetic. A lot of people use this "revegging" method, where they just leave a few lower shoots during the harvest, then bring the plant under the light for an 18/6 or 24/0 light cycle. It takes a while for the girl to recover from the stress and get back into a normal vegetative phase, but after that, she'll get pretty bushy (monster cropping), and then she can go back to 12/12 to flower. Have you tried this technique, or are you just planning to test it out? Happy Growing Growmie🌱
