Hi Shagrath
Defoliation isn’t for everyone in all setups.
It should only be used in specific situations. If you do defoliation the wrong way it will hurt your plant and reduce your yields.
As one example, defoliation doesn’t appear to be effective at significantly increasing yields for outdoor plants. But for indoor growers, cannabis defoliation done right results in larger yields.
Suggestion
Just before switch to 12/12 – After defoliation
You start by removing the biggest fan leaves, especially any that were hand-sized and bigger.
Some growers like to defoliate the bottom 20% of the plant at this stage. Make sure not to disturb bud sites, and always leave enough leaf cover that you still can’t really see through the plant very well. The plant needs a table of leaves to power the growth and stretch the way we want in the next few weeks! I think it’s common to go overboard at this stage, so I recommend taking a few less leaves than you think.
3 weeks after you switch to 12/12 – Do a Second Defoliation
Plant started growing buds, and
re-leafed itself in that time!
At this point You only taking Down the biggest fan leaves, making sure not to disturb the growing buds.
Again, you still shouldn’t be able to see through the plant very well after you’re done, your plants need leaves to fattening the buds.
Nothing else needs to be done after this point.
Hope this helps and good luck with your grow.
