heya mate,
basically i have seen this question time and time again and you will always get different answers from different people. (i was asking this not long ago lol)

what i found was that when i tried to LST my current crop they didn't really respond happily. I gave up on that idea and decided to do some topping & they loved it!

The cutting does stress the plant and slow growth but my strain likes it :thumbsup:

Also don't forget some people dont do either as they have enough space to let them go crazy!
But i found you will never get the same answer twice, but experiment and you will decide for yourself eventually
