Yes I am planning on bringing my plant in over winter.
However the HUGE plant I refer to is only 1 year old. He is starting an experiment with 2 identical plants 1 normal growth and 1 pruned growth. He is testing for single year growth and production. From his description this method helps even during year 1.
Personally I do not plan on getting peppers off this plant this year. I am going to use this method of cutting and bushing all my pepper plants and just stop when it is time for them to start producing. but in 1 month I have gone from seed to pepper plants with a 1/4" diameter stalk and is making branches off of that.
here is his video so you can see what I am talking about. It is a 3 part series over a year to get to the end product.
Look around the 3 minute mark
