Robertsanswered grow question 3 years ago Top of plant is one answer. The other can be done several ways. I did a diary called Larry lemon. Where I took daily pictures from seed to smoke. I show the size and day I first lst my plants. Then every day after. I harvested over a quarter pound dry off that auto. I use 12 gauge solid copper wire and make hooks. Then anchor them into soil or side of potter. The object of lst is to bend the plant over. They do get woody and can break the longer your wait. Is why I start soon and stay on it about every other day. Even if all you get is a good lean that is beneficial for light to get to inside of plant to stimulate growth. Hopefully this helps and happy growing 🌱🌱🌱
