I get extremely complex branching, on 4 foot plants and a lot of the branches are the secondaries that grow from the bottom branches. I pull all those "out" of the center and pull them down.. They are flexible enough that they usually don't even crease... Any branch that doesn't have a "row" of buds that don't look like they will form a good sized kola, I pull them out from the center of the plant and down... but still keep them on the plant.
Then when harvest comes, those are all cut off and used for making bubble hash.
Any leaves that have a petiole that is longer than 3 inches, get removed. Any leaves that grow towards the center of the plant get removed, unless they're attached to the main kola, but, even then, if the petiole is longer than 3-4 inches and blocks a whole mass below it, I'll cut it off.
So, the whole idea that there is a strict rule of "No touchy the planty" , is not alwas the case. Sometimes I end up at harvest with the original fan leaves still on the plant at the bottom, sometimes I don't.
It just depends on all sorts of things from environment to the plant itself, as Mr. Dirtbag says.
The one thing about my plants most times. Is that the canopy stays amazingly flat, without training so much. I start them off with T5 Flo's and then switch them to 1000w hps for flower, and they tend to keep this flat shape, but then the secondaries will come in like crazy and start choking the hell out of the plant...
Sometimes though I get one that wants to grow to the moon, ends up with a foot long kola, Usually I just bend those over and tie them off to a screw I put in the wall with a nylon paracord.
I personally am not against stripping to get maximum light to a bud sight, but, I only see the usefullness of that myself, when it's necessary. We as indoor growers have to understand that sunlight penetration is WAY stronger than any light we can provide. Those shaded spots in a indoor grow are getting massive amounts of light if it was an outdoor grow. Anyway, I can get long winded and say little.
