I doubt you've read what's available but whatever. Read this thread and you'll find everything you need to know about early sexing. Good luck.

Each plant and strain is different. Some can take months to show early sex, some can take a couple weeks.

Good rule of thumb is 4-8 weeks

Depending on lighting schedule/ indica or sativa........

thanks hearmenow i had already read that and i still cant see where it says how early
ganjagod my plant is in the greenhouse so just gets natural light and as for strain im not sure as they were given to me as seeds
cheers Bifter

What you want is alternating nodes. This tells you it's ready to be flowered. You change light to 12/12 and then you should see some tiny little spike come out. If these little spikes have a little ball on the base, chances are it's a male. You'll need magnification to tell. If it's a female and the plant is still small at that point, you can revert back to vegging. Personally, I would just wait until you can definitively tell the sex. This will usually occur after about 2 weeks of flowering. That's not a rule of thumb but just a guide.

So that could be quite a while in the greenhouse? I hope it is female if i have to mess about with it for a long time

Bif, I know how you feel. I think we all do. Unfortunately that's how it goes. You have a 50-50 chance of a female. There is another excellent post that outlines additional steps you can take to enhance your chances of a female. There are no guarantees but it's worth a shot. For reference, I started with 7 plants and 5 made it all the way to the flowering stage. Of those 5, 2 turned out to be female. Another poster on here started with 4 and all 4 were female. Luck of the draw....
