The male plant produces pollen sacks which, when ripe, burst and scatter pollen to the female plants. The female plant produces white hairs at the internodes and top cola (head) of the plant during flowering. These hairs (pistils) begin to curl slightly and grow longer and thicker. The top cola should carry the most pistils. These pistils are sticky too touch (do not touch them too much! they also contain your much wanted THC) and begin to cover in resin over the flowering period. The reason for the stickiness is that it is used by the female to catch falling pollen. If the female plant is not Pollinated she will try to grow more sticky areas. Hence the results of a sinsemilla crop Bigger and Better Buds!
Force-flowering a cutting is probably the best early sexing method out there. Simply take a cutting from the plant that you want to sex and place the cutting in a cup of water or into a cloning medium such as rockwool. Give the cutting 12 hours light and 12 hours total darkness. The cutting will flower and display its sex. Clones will carry the exact same genetic make-up as the plant it came from, including sex.

Now is the time when you should be hoping for as many females as possible and that all your work has not been in vain. You closely look at the new growths (Calyx) to see if you can identify your plants sex, but it is still too early to tell.
By now you have managed to set up the basic environment in which your indoor plant will grow. You have your plants in some pots under a grow light with some white surfaces nearby and some fresh air in the room. You have also been watering your plant properly and you have been adjusting the pH and Nutrients in the soil.

THE MALE/FEMALE THING or HOW TO SEX YOUR PLANTS
During the strict cycle of 12/12 she will eventually reach a peak period of flowering. Along with the flowering cycle the plant will also fill out more. More leaves, more branches and more flowers. Your plant will start to almost take the shape of a Christmas tree. The lower fan leaves will be stretched out to the max in order to receive the most light. Running upward in a cone shape she will get tighter with floral and leaf development.
