Sexing Marijuana Plants

Sexing marijuana plants is a critical portion of the increasing and breeding method. Cannabis plants are frequently dioecious plants, which suggests that they will create either female or male reproductive organs. In specific environmental situations, nevertheless, cannabis plants can be monoecious, also identified as “hermaphroditic.” Monoecious plants function each male and female reproductive organs.


When increasing from seed, growers hold a close eye on early plant development to make positive they know which plants are female and which are male. Figuring out the distinction amongst the sexes tells growers irrespective of whether the plant will be made use of to develop trichome-wealthy and dense flower buds or to create thrilling new genetics. If you are working out your green thumb with cannabis plants, here’s every thing you really should know about sexing marijuana plants as early as attainable.

The Importance 

When cannabis growers get a marijuana clone, the clone will have the very same sex as its mother. Having said that, cannabis grown from seeds, even these advertised as “feminized seeds,” demands cautious focus in the course of their development phase. There is a powerful likelihood that as several as half of your marijuana seeds will develop into male plants. If you are attempting to develop female flower buds to their maximum prospective, male plants can ruin a harvest when they distribute pollen.


A single male marijuana plant can pollinate an whole cannabis develop operation. Some professionals even suggest a minimum distance of 10 miles amongst outside marijuana fields to prevent cross-pollination. Marijuana pollen can attain even additional than that, but the danger is drastically lowered. Marijuana pollination is an critical portion of breeding new hybrid and steady genetics. When industrial breeding operations use hundreds of plants and hunt for the most desirable phenotypes, residence growers are frequently restricted to compact-batch breeding by government cultivation limitations.


If a female marijuana plant gets pollinated, it stops increasing flower buds and switches to seed production. Non-pollinated female plants are also identified as sinsemilla, which means “without seeds.” These plants create the most terpene- and cannabinoid-wealthy flower buds. Removing male plants from the garden as quickly as attainable keeps your female crop intact and increasing flowers.

Sexing Marijuana Plants

In order to establish the sex of your marijuana plant, you will have to have to spend close focus to the region of the plant exactly where sexual organs develop. A cannabis plant’s sexual organs develop at the nodes, exactly where the base of the leaf stalk (petiole) attaches to the primary stem Growers really should use a 10x loupe or hand-held magnifying glass to find and monitor stipules at these nodes. Stipules resemble two narrow spikes, a single on either side of the node. Examine the node area every single day for calyxes emerging from the stipules.


  • If the calyx is raised on a compact, brief stem, and staminate primordia (compact sacs) are increasing amongst the nodes, it is most likely a male plant.
  • If pistillate primordia (two fuzzy white hairs) are increasing amongst the nodes and the calyx is not raised on a compact brief stem, it is a female plant.


Growers can get a superior notion of irrespective of whether a plant is male or female earlier in the flowering cycle, even without having seeing the reproductive organs. If seeds of the very same strain are planted at the very same time, the distinction in sex will generally manifest in distinctive heights. Female plants have a tendency to develop shorter and bushier compared to male plants. Female plants also have a bigger quantity of leaves close to the major than males (exactly where flowers will type).


As you develop additional plants, you will discover to establish the sex of your plants in the course of the vegetative stage of development. Novice growers could take a couple of weeks longer to establish the sex of the plant. You really should be checking the nodes every single day for calyxes increasing from the stipules. At the quite most up-to-date, plants will show their sex two or 3 weeks just after the light schedule is switched to 12 hours of light and 12 hours of darkness every single day.

Removing Male Plants

Get rid of male marijuana plants as quickly as you establish their sex. Male marijuana plants create a scant quantity of flowers with quite low THC levels. Nevertheless, there are several fantastic utilizes for male cannabis plants. Rather of discarding your male plants, right here are a couple of techniques to make the most of them:


  • Breed new genetics by pollinating pick female plants.
  • Juice the leaves of male cannabis plants or place them in a salad.
  • Extract cannabinoids from male plants’ leaves, stems, and sacs to create concentrates.
  • Use the soft hemp fiber developed by male plants to make clothes and other textiles


Sexing marijuana plants gets simpler the additional instances you do it. At 1st, you could have difficulty identifying the distinct traits of the cannabis plant’s male and female reproductive organs, but every day observation assists you catch these male plants early.
