I thnk you guys for all the info...I have been studying all of this for months and I am aware of the steps in determining sex. My question is whether or not it is possible to do the following in this order:
1. veg for 48 hrs
2. force flower just long enough to determine the sex of each plant (approximately 1 week).
3 eradicate the males
4 force the successful females back into vegetation to get more plant growth (approximately a month)
5 resume flowering for two months until harvest.

I guess I am just trying to find the quickest way to get to vegging 5 plants all females.
Plant 2 feminised seeds, of two different types (white widow + cheese I think I used, but whatever you desire). When the plants are 4 weeks old take 2 clones off each, flower all of them at 8-9 weeks (all mine were female as expected). Just before starting to flower take another 12 clones in total - from the original 2 plants + the 3 clones.
6 female clones then vegging, while the 5 main plants flower - all guaranteed to be female forever onwards - or until the process is stopped.
In the very unlikely event that one plant turns out to be male, simply disgard the clones and original plant, and take more clones from the other. I have never had this, i cannot imagine 2 feminised seeds both turning out to be males.
Obviously the clones were about 18 inches shorter than the mothers, so were propped up with large plant pots upside down, so the top canopy was at the same level.
Naturally the next 5 cloned plants will be more uniform.
Im no expert btw, but the clones have had 100% success + im growing indica/sativa cross feminised seeds, which are mainly indica. The lights are envirolite combos, the flowering room is an airing cupboard with a fan, the veg room is a small indoor greenhouse in the same room covered to minimise light. The light is dim from the veg area, and the main room in dark cycle is protected further by a door which has only a 1cm gap, it is not TOTAL darkness but is overkill for how dark it need be (remember they can flower without disruption from moonlight outside + it's nowhere near that - you can't see the plants in the dark cycle with the naked eye at all).
That was rather wordy + I dunno if it's any help, but I'm pleased with the method + results so far.
In short:
Feminised seeds 2 - target=5 flowering 6 vegging
Clone as quickly as you reasonably can, flower all 5 4 weeks later (after taking alot more clones to separate).
