Is early sexing then reverting to veg. safe?

hey all, i have 8 ak-48 bout 5-6in. tall and have put em under a 12/12 cycle starting 2 days ago to sex them early...my reason is that last time i vegged 14 plants in my room and had only 3 females...bad because i only have 9 square ft. to work with so i could of ultimately allowed the 3 females to grow a great deal bushier b-4 flowering if i would of known earlier...i want to rid the males this time and then put them back on their 18 hr. light cycle so they can veg to bout 18 in...is this safe...i hate to waste the space when its so limited but i'm worried bout the risk of hermies and sex problems...what u think?

A better way to do it would be to take clones and sex those, then flower the corresponding females.

Its gonna take them a while to turn back to veg.

Take a very meager clone from each plant and plunge it into darkness

clones take too long, you need to know NOW! right? it is OK to sex early . You are at the perfect point so 12/12 for a week (probably even less) should be long enough to know for sure. Post pics too if you can that is the easiest way to tell, let others decide! they will slow down a little after going back t0 18/6 but they will be fine. This is the only way I do it.

From what I've read it's cool and you can revert, stick em in the dark for 24 hours and then do the 12/12 thing, course this is just what I've read in a reputable mag. Just a virgin and can't even get past the seedling stage!

I do the clone thing. I try to avoid flowering a plant before it has reached maturity (alternating) to decrease risk of herms. Every little bit helps! :D
