BID,
I highly suggest using google: Defoliation: Hi-Yield Technique?
Then plan on spending two weeks reading, and you'll have a reasonable outline and starting point. I was fortunate in that the author of the topic and thread came to my grow (2 grows back) and gave me some guidance. But I've still had to learn and adapt a bunch. This grow is just an example of that adapting.
Another example of adapting occurred just this afternoon. The plant in the back right was leaning into the back left. Even though I had it's main stalk tied tight, it was still leaning. What I found was too many of my really long bud branches were just sent the wrong way and as they daily gain weight it is becoming a major issue. So I started pulling them back the other way and now tomorrow I'll have to set two more strands of twine and try like hell to manage the branches better with max light and still allow them to bulk without breaking.
Funny thing, way back in early flower when I was bending and breaking I broke a main branch in such a way that even tape and twine support didnt fix it. This was a main branch on the largest front plant and I would guess it cost me no less than 3 oz in yield, yet I fully expect to still get at least 7oz from that plant.
I certainly can't call myself an expert on this technique. But I am learning how it works and further how to respond to the impending nuances as they come up. Maybe after next grow I'll be more prepared to offer a better opinion and guide. But for now, all I can do is share what I've learned from that thread and my short time of experience doing it and the things I've run into and learned here in this journal, the last journal and my next grow, which is in veg now and not journaled as yet.
That being said I'll try to lay out some of the basics when I have time. It's too late now and I need to get some sleep before work tonight.
