One of the platforms of SOG is short veg and faster turnover. I agree he could have yielded more with another two weeks of veg but if you look at it on an annualized basis, that first two weeks of veg took away the potential to harvest 1 entire grow. Granted this is an ideal scenario, but if you could veg for 2 weeks in another location while finishing up your flowering plants, you could add one more grow per year. Don't think of yield on a per grow basis, think of yield on an annual basis.
If yield per grow mattered I would have 10ft ceilings and veg for over a month. But that's no efficient growing IMO.
2 weeks more of veg per grow x 4 grows per year = 1 wasted harvest of 3-4lbs. Will vegging this last grow for another 2 weeks have doubled his yield? Highly unlikely.
After watching this grow and exchanging some emails with Bob, I know exactly what I'm doing after my harvest in a week or so. SOG mofo's.
