rhodes68answered grow question 5 years ago Well if you do a good job of LST, it can produce more, note "can".
A lot depends on the plant/strain, topping just adds a growth tip and bushes out the plant until the tops recover.
LST is going to bring bud sites into the light that topping just cannot duplicate, and keep plant size sort of managed.
That said topping is done in a few minutes and thats it, LST will have to be touched up several times a week at certain stages.
So... you da man
