This is an example...
of what happens when you prune branches for the effect of making your plant bushier. Notice I sniped the center branch about a week ago. Back then, those two side branches were just barely visible tufts of green, not yet leaves or branches. Now they're doing exactly what I had pruned for, to produce two branches at the same top level where before there was only one. Access to the greatest amount of light by the greatest amount of branches, and therefore bud sites, is a way to ensure heafty harvests in healthy plants.
I supercrop to increase yields
I have supercropped before and have recently come to the personal conclusion that it does really work. My largest and most developed colas last crop were on supercropped branches. Just take a tender branch in your fingers and pinch and twist at the same time until you feel the insides start to collapse under the pressure of your fingers. The branch might droop slightly, but this is what you want. You're actually damaging the insides of the branch. We are trying to damage the vascular (water and nutrient carrying "veins") tissues so that they double in size after a week or so of healing themselves. As in human muscle, we must slightly damage our muscle tissue (by exercise) before it heals, larger and better able to move fluids to and from places in the body that need them. So by supercropping, you're creating body builder Pot plants!
This is the flowering...
area after pruning leaves, branches and supercropping. I didn't take a picture before, but if I had, you'd see that they used to be very very cluttered with light blocking leaves and useless bottom branches which never catch up to the producing branches, and actually cause a drain on resources more than anything. In a week these will be covered in young but well-lit bud sites. The front half of these girls are Yankee Platinum clones the back are NL.
To help increase yield...
and to decrease overall height of the plant, I top (snip the main growth shoot) when the plant has four to five sets of leaves. This is at the fourth set. This action will cause your plant to react by extending those tiny green tufts of green on the side of the stem into full-blown branches.
Proof that it works...
This is what happens after about 5 days to a week after topping. You can see the great increase of side shoots. These will, with some training and future pruning, all compete for light at the top of the plant, instead of being relegated to the middle or bottom of the plant, shadowed by the main cola that you didn't snip when you had the chance to do so.
