You could just take a cuttings and put that under light for a few hours a day then place them in a light proof area for the rest of the day and they would show sex that way. It would be a small hassle but since your limited on space you could do it that way without stressing your plants. There are some growers who "revegg" plants that have been fully flowered , so unless the strain is hermie prone it should be ok. You could use a product like reverse to counteract any stress induced hermie traits your plant might have also.

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 Rating: 5
