cut it early, then cut the next 2 main branches 2 weeks later then cut the main 4-6branches 2 weeks later. Then flower. Use training wire to hold them all up close together near the light. I'm by far a pro but I know that everyone who smokes my shit says "wow". This just seems to work for me, there are also more time consuming methods that im sure will yield more like putting a screen over your plant and folding all the leaves under it as they try to grow out until you have a carpet of green, then you flower it and only buds will grow through the screen. I'm too lazy to try this method. I flowered this lil 3 foot plant in my avatar with me on my knees you can see, and pulled 3.25 oz dry "MY personal best" but only been growing for 6 months and learning more every harvest.
