Trimming Growth during Flower

Would i be right in saying that removing lower growth in flowering will make higher growth more predominant.

And....

Removing upper growth will encourage lower growth ?

or is this just shit.

dont htink your right on any part bro. but im not sure
if your lower branches dont grow as much as you like em to, get some cfls support

I havent tied removing all lower growth. But I hear it will make the top buds bigger.

Topping / Fim will make the lower bottom shoots catch up with the top so you have many tops.
You can also do this with Low Stress training, its less stress but more work to slowly bend the tops down level..

Dont people pre-trim their plant BEFORE flowering to get more dense nugs; less pop-corning?

Doing it during flowering isnt a good idea; more stress, loss of food.
