I haven't tried something so extreme as swazzing. But I do like to lst and attempted fluxing(which worked really well) and mainlining (not so well). I always remove undergrowth that's not receiving any light and remove any leaves blocking bud sites but in my opinion that's enough, they do use the leaves to absorb the light and transform into plant food, every plant does (I think) but selective pruning is definitely beneficial! 🌱😁👍
