The obvious answer is to get a good machine but ur probably w this being only ur 2nd grow not gonna do that quite yet.
First if all, w practice ur gonna become more efficient so dont get too weary.
Heres a few things i like to do to make it a lil more bearable.....
U can start in veg and early flower by raising the skirts of ur plants and removing the bottom shit thats gonna make for tuff trimming come harvest time.
The next thing is during the actual harvesting process , remove any leaf that u can see a petiole on. The more u do b4 u dry the less u have to do in the end. Imo, its much easier to pluck as much as possible by hand b4 it dries and conforms to the bud.
I prefer to stand while trimming as opposed to sitting down. I trim over a bench that comes up almost to ur sternum so im not hunched over.
Another lil trick is to have multiple pairs of scissors. Keep the ones ur not usin in a cup of alcohol and once a pair gets gummed up put em in the cup and rotate ur scissors. When u take the next pair out of the alcohol give em a quick wipe w a dry paper towel. By the time that pair is gummed up the ones in the cup will be ready to use again.
Cut the branches into manageable size pieces. Dont try to hold a big ass branch and trim it. Assuming ur right handed, hold the stem in ur left hand while w ur right hand rapidly open n close the scissors. Ur left hand is actually doin most of the work. All jr doin w ut scissor hand is opening and closing the scissors.
Start at the base of the buds and work ur way up.
