Sexing Marijuana Plants

Marijuana plants are either male or female. The male Marijuana plants produce pollen which pollinates the flowers of the female Marijuana plant, which once pollenized, produce seeds. If the female Marijuana plant isn’t pollenized (if there are no male Marijuana plants nearby producing pollen), the flower/buds continue to develop and produce THC. Female Marijuana plants which are not pollenized are referred to as sinsemilla (without seeds). Usually 30-50% of the Marijuana plants are male.

Cannabis in temperate climates begin to show his sexual identity by the end of July (end of January in the southern hemisphere) in different dates according to the varieties, Marijuana being the resinous flower of female cannabis plants intended for seed production, in absence of pollen buds turns out pure sensimilla weed and is gentle and sweet to smoke.

Males are often, but not always, tall with stout stems, sporadic branching and few leaves. Males are usually harvested except those used for breeding, after their sex has been determined, but before the pollen is shed. When harvesting, especially if close to females, cut the Marijuana plant off at the base, taking care to shake the male as little as possible. This helps prevent any accidental pollination by an open male flower.

It is very important to get rid of male plants on time, as they are unwanted pollen carriers. By the early flowering stage male cannabis, if compared to female’s, shows quite a different structure but the characteristic excrescencies would be the sex indicator this are called primordia and will emerge by the side of the third or fourth internodes in the main stem.

Female cannabis are completely revealed when the characteristic “V” shaped pistils become visible, all this to a close observation. Outdoors males will uncover themselves approximately three weeks before the females, indoors sexing of both males and females happens within a week to ten days according to the variety.

A hermaphrodite, or hermie, is a Marijuana plant of one sex that develops the sexual organs of the other sex. Most commonly, a flowering female Marijuana plant will develop staminate flowers, though the reverse is also true. Primarily male hermaphrodites are not as well recognized only because few growers let their males reach a point of flowering where the pistillate would be expressed.
