Question about sexing my plant!!!

So i have had my plant for about a month now..... had it on about 24 hr light should i swithc it to 12 on 12 off???? its about 8 inches tall now! Just curious about what i should do to find out if its male or female?????? Thanks guys for all the help btw!!!!!

8" in a month?? What are you using for your light? Anyhow if its from seed wait another month. It will start to show pre flowers then you can go to 12/12. Some people dont wait that long but its a good idea to let the plant mature some from seed. Kinda let it hit puberty lol. If its a clone you can go to 12/12. say the mother plant is 100 days old...so is the clone.
