BWD if your haveing problems with the plants growing too tall, on your next grow try LST (low stress training) thats when you bend the plants from a very early age and you can get them to grow horizontal instead of verticle , you can end up with some nice big colas as theres no branches in the way so the light distribution is better, if you do a search you will be able to find plenty of info in the grow section on LST.
just picked up a small amount of northern lights haven't smoked it in years Mmmmm lovely aromatic tasting smoke
