Ive learned a good bit from him, although I think he cuts a few more days off than neccessary. My 1st grow I accidentally top my NL at day 37-38 and she did great with over 4oz. I have had plants not do much till stretch and then reach my lights. I also veg every plant longer than most do. I dont stitch till day 35-42 unless plant is ready sooner. If everything is perfect 20-25 is my sweet spot. She is at that end today with enough nodes. Every plant goes it's own path which is why nature is awesome. I will let her go another day or 2 and see. If she picks up momentum she should be good to go, if not let her be. I really want to top her tho. I'm the kinda guy that if you tell me "Oh no, you cant do that" there is no doubt I'm gonna do it hahaha.
