Sexing of marijuana is identified by rudiments of inflorescences, which usually appear after 4th week of vegetative growth.

Female plants
Female plants are represented by pear-shaped inflorescences with pistils in them. Female plants often don’t show their pistils before blooming, so don’t hurry and “kill” a plant straight away.

Male plants

Male inflorescence is like “ball on the leg”. If you aren’t sure about plant’s sex, you’d better wait a little and make sure that pistils haven’t appeared and balls begin to form fascicles.

Hermaphrodites
Hermaphrodite is a plant with one sex which has genitals of another sex. In most cases, blooming female plant educes male flowers, but it can be vice versa. First of all, male hermaphrodites aren’t spread much because not many growers allow their male plants to reach blooming point when pistils may appear.

Hermaphrodites are in disgrace. They let the pollen out and broke sin similla’s crop, pollinating all female plants in the room. Received cannabis seeds aren’t valuable, because parents-hermaphrodites often demise their properties.

Suspicious male flowers appear on the last days of female plants’ blooming. They don’t let the pollen out and they aren’t signs of harmful hermaphroditism.
