Im actually in the same boat. Im just starting week 4, so Im on day 22. I have about 8 branches from thebottom that never stretched up to the top. They are growing buds, I have hairs all over. I need to know if I can cut them off and get some root hormone and put them in smaller pots. I cant imagen them growing that much weed as my plant is about 28 inches tall, shes huge. But ya, is there a guideline for how long in you can clone, and on top of that maybe someone can put a link here for where I can read up on cloning. Id like to clone just so I can make more female plants from the start but I havnt been able to find any decent information stating whens a good time to start before flower, how long after flower, exactly what I need to do inorder to be successful.
