female or male??

at what age am i going to be able to tell if my plant is a male or female?


its at about 3 weeks right now

well first you have to flower the plant

You should get preflowers around 5 or 6 weeks. Those will tell you if you have males or females. Otherwise like the other guy said you can change the lighting then about a week or two from the light change you should know.

yeah depending on the plants genetics it will show preflowers while its vegging but usually it shows after you switch the lighting from 18/6 to 12/12 and wait about 2 weeks
