I think that trimming the lower buds helps "put the energy to the tops" and it also makes trimming a lot easier. Last year I was kicking myself for leaving so much popcorn bud. Takes so long to trim and dries to almost nothing. Anything that looks weak and scraggly gets chopped. Its tough to do now, but I will be glad I did it later. And I think you will get the same weight, just all in the tops rather than spread out into tiny nugs.
I do it with my outdoor plants. I get limited sunlight so I practically trim the whole bottom halves of the plants, especially on the insides just because I know they wont be shit.
seems to do better when trimming, helps with airflow too.
Do you ever trim the bottom branches during flower when you have a better
idea of what is going on with the visible buds in terms of production?
Do you suppose this goes (ridding lower buds and branches) for outdoor plants with plenty of sun as well?
