i have found that it is not really necessary to prune very much. a less stressful way to get air and space to the plant is by tying branches down and out with some string. this will spread out the folliage.
If you are going to trim, do it sparingly and all at once, dont trim a little today, a little tomorrow, a little the next day. only take fan leaves from the bottom that are not getting uch light and are constricting air flow below the plant. also, it helps to ater the plant with superthrive when you are stressing the plant.
I would say the opposite of what your saying.
Do not take all the leaves at once as this can shock the plant,trim a lil bit there a lil bit here over a period of weeks,never all at once.
I always trim my plants in this way and have done for years,they never seem to mind in fact i just end up with fairly leafless lumps of bud which is exactly what i want.
Your plant looks like it has to much leaf and has been heavily topped but if your not going to bother with getting a lot more light on the plant then i don't know if it would be beneficial to you to take leafs away as this wont help the plant unless you provide some kind of hid light source.
This is my own example of what to expect from a trimmed plant that is under a hid light source
And as you can see here it was once very leafy and over a period of many weeks i have removed leaves that shaded areas that i didnt want them to.
Go easy on the plant and remove only 4-5 a day.
This plant has had leaves removed from it since it was about 3 weeks old.
too late this year, but i think next holiday season that would be a fun undertaking.....she was asking if i'd let her put lights and stuff on it and i said yes, then she asked if she could have a star on top...i told her the star is already on top...that cola of chronic! what better star could there be.
