Haha jerk, but that was funny shit.
If you grow a plant, from seed, under 12/12 from birth, then it's not going to show sex until it decides it's ready. This depends on your lighting, feeding, soil, temperature, humidity, age, loving, genetics, attention, and space you give it. I probably missed something but they all take different times.
I'm sure HPS 12/12 grows take a few weeks to show flowers, while CFL could take 4-5 and T5's could take like 6 or something. It all depends on the plants growth rate.
Plenty of 12/12 grows from seed exist, good luck.
