From seed it will be hard to hit the oz mark, going straight 12/12.. well spose it depends on the enviroment, i.e. lights.
It would be easier/better if you went 12/12 from a rooted clone, as more decent yields and faster maturation as of its sex has already been established. If your looking for quick yielding, SOG is the way foward.. if you ave a seperate veg box perpetually is great choice.. i think, well i've just started it.. will be chopping the first lady of the cycle tomorrow.. then it will be a chop every 2weeks... cant be bad

Strain choice there is loads out there.. just pick what suits you.. what suits you will not suit everyone else. Although couple of exceptions.. theres a slightly new one around too,

..everyone one seems to love it, got some meself sitting in the corner of the veg room.
