Sexing Marijuana Plants

Sexing marijuana plants is a essential aspect of the increasing and breeding course of action. Cannabis plants are normally dioecious plants, which suggests that they will generate either female or male reproductive organs. In specific environmental situations, even so, cannabis plants can be monoecious, also recognized as “hermaphroditic.” Monoecious plants function each male and female reproductive organs.


When increasing from seed, growers preserve a close eye on early plant development to make positive they know which plants are female and which are male. Being aware of the distinction among the sexes tells growers no matter whether the plant will be employed to develop trichome-wealthy and dense flower buds or to generate thrilling new genetics. If you are working out your green thumb with cannabis plants, here’s almost everything you should really know about sexing marijuana plants as early as attainable.

The Importance 

When cannabis growers acquire a marijuana clone, the clone will have the identical sex as its mother. Having said that, cannabis grown from seeds, even these advertised as “feminized seeds,” demands cautious focus throughout their development phase. There is a robust likelihood that as quite a few 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 complete cannabis develop operation. Some authorities even advise a minimum distance of 10 miles among outside marijuana fields to stay clear of cross-pollination. Marijuana pollen can attain even additional than that, but the danger is drastically lowered. Marijuana pollination is an critical aspect of breeding new hybrid and steady genetics. Although industrial breeding operations use hundreds of plants and hunt for the most desirable phenotypes, dwelling growers are normally restricted to modest-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 recognized as sinsemilla, which means “without seeds.” These plants generate 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 need 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 major stem Growers should really use a 10x loupe or hand-held magnifying glass to find and monitor stipules at these nodes. Stipules resemble two narrow spikes, 1 on either side of the node. Examine the node area just about every day for calyxes emerging from the stipules.


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


Growers can get a excellent notion of no matter whether a plant is male or female earlier in the flowering cycle, even with no seeing the reproductive organs. If seeds of the identical strain are planted at the identical time, the distinction in sex will ordinarily manifest in unique 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 far more plants, you will study to establish the sex of your plants throughout the vegetative stage of development. Novice growers could take a couple of weeks longer to establish the sex of the plant. You should really be checking the nodes just about every day for calyxes increasing from the stipules. At the pretty most recent, plants will show their sex two or 3 weeks soon after the light schedule is switched to 12 hours of light and 12 hours of darkness every day.

Removing Male Plants

Eliminate male marijuana plants as quickly as you establish their sex. Male marijuana plants generate a scant quantity of flowers with pretty low THC levels. Nonetheless, there are quite a few excellent utilizes for male cannabis plants. As an alternative of discarding your male plants, right here are a couple of strategies 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 generate concentrates.
  • Use the soft hemp fiber made by male plants to make clothes and other textiles


Sexing marijuana plants gets much easier the far more 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 everyday observation assists you catch these male plants early.
