I harvested 3 gals 2 months back for a week. I let each bud mature individually, took me about a week, 200g of prefectly matured bud. The last 3-4 days, all the lower buds got bathed in light, and matured nicely too, though they didn't grow much bigger, they did seem to get more compact from that.
Theres even a theory that if the plant hermies the last week, it will increase weight. The buds do swell up with immature seeds, and fill them out, but it probably doesn't do much for the quality.
