Nice grow, I would let the plants veg until they are "hugging" the bulb from all sides. Seems like your set -up could really net some YIELD, if grown properly. Just my 2 cents-
However, one can flower 12/12 -from seed if so desired. Imo, it doesn't make any sense to veg past a certain point, as plants will stretch massively and the light penetration diminishes rapidly indoors. It is true that generally bigger plants produce a bigger yield. One has to experiment with what works best under their specific set-up.
You are right some 100% sativa's breeders recommend an short veg time (1-3 weeks) of just as you mentioned start you grow with a 12/12/ cycleHowever, one can flower 12/12 -from seed if so desired.

Sure, and many learned growers recommend growing hazes or landrace sativas with 0 veg.time because of their insane stretch and unruly/aggressive vertical growth. If you have some experience however, one can even tame these strains indoors under CFL's- (not really recommended). My last mini-grow consisted of Speed Haze (ssh x j. herer) and I only used 3 65w/ CFL's to grow myself 3 plants on a 12/12 from seed regiment. They tried to grow "through the roof" so I had to severely prune/Lst/super-crop them. Ended up with about 1.25 ounces of good smoke, giving me a long-awaited break from smoking the local SCHWAG.
That's the fun of it; growing something you never had before and always thinking about the harvestI have some Durban Magic from Seeds of Africa. IF (?) I ever attempt running it indoors under my 150w HPS I will only go 12/12 from seed. Outdoors, I would still plant her a bit late in the season since I don't really want 12' tall trees to wrestle with. Never grown Durban before, so I will have to see how she goes and "play it by ear".
