12/12 from seed, when will sex show?

Hey every one i got a quick question. I am going to be starting off with some bag seeds and i am growing stealth so i will be doing 12/12 from seed. When will the plants start showing signs of male or female? or is this just a dumb question cause it is based off strains? lol

roughly 3 weeks in

you should run 24-0 for lighting from seed to about 2-3 weeks grow time and then switch it over to 18-6 so it can veg and gain energy then it will show in there more then likely

well i am doing a Pc stealth grow so i have to keep the plants pretty small, how much will it grow in a weeks time of 24/0?

Keep doing what you'r doing with the 12\12.Sex should show in 14 to 20 days.Seeds started in this way don't do a lot of branching & grow a large central cola, so you can grow plants closer together.Plant density makes up for the no-veg time hight wise.Got to be careful of burning young seedlings with HID lighting.Most 12\12 growers start with floro maybe 3 weeks & then switch to HID to the finish.
