Haha yeah for me there is only 2 of us, sometimes 3 if lucky, ever trimming and we start at around 10pm and trim until 5am we can take out a whole plant in this time. The assembly line technique helps blow through the trimming.
1 person pulls large water leafs and other materials not going into the hash pile and throw the leaf into a large black trash bag.
next person separates the branches into manageable handling sizes for trimmers to work with (for me I dry on racks no space for hanging plants, so the nugs are cut off the branches at this time)
next person (sometimes after the first 2 jobs are done and there is only the 2 of us, we both tackle this job) will do the final trim around each bud and put the nugs into a bucket to be transfered to the racks after we finish.
Treat your trimming sesh like a fast food restaurant, give each person a simple task, do not combine it with anything else, and production should go up.
Less time getting up and moving around the more trimming you get done. Just trying to put out what has help me get faster at trimming come harvest time. My first MPB harvest it took me 3 days to do one plant. Thank god there was only 4 that time.
