**how to sex a plant early??**

i have 2seeds off a plant that when herm in the last fiew days ov flower, they germd real quick and popped the soil all within 3days, theyr currently on day 3 and already 2inches tall with their first set of pot leaves.

what i want and need 2 know is how can i sex the plant without puttin it into a 12/12, i only have 1 room so cloning is not an option as is building a flowering room!!!!!!!!!!

what are my options?

i wanna do a SCROG this time and dont wanna train those babies through the screen and find out theyr male or half male half female, as it would be a nightmare trying to untangle the males!!

wot can i do???? please help,

im realy racking my brain about this!!??

thanx for the reply roseman, does the bag trick actualy work? some1 told me they tried that and it killed the whole plant wich i found hard to believe!!
so u completely make 1 branch lightproof on a strict 12/12 schedule? will that stress the plant at all?

if shes a female can i clone her and gro the clones on under 24/7 ready to fill my screen? thanx roseman
