Sexing Marijuana Plants

Sexing marijuana plants is a vital component of the expanding and breeding approach. Cannabis plants are frequently dioecious plants, which implies that they will generate either female or male reproductive organs. In specific environmental circumstances, on the other hand, cannabis plants can be monoecious, also recognized as “hermaphroditic.” Monoecious plants function each male and female reproductive organs.


When expanding from seed, growers hold a close eye on early plant development to make certain they know which plants are female and which are male. Being aware of the distinction in between the sexes tells growers whether or not the plant will be utilized 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 all the things you ought to know about sexing marijuana plants as early as attainable.

The Importance 

When cannabis growers get 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,” needs cautious consideration for the duration of their development phase. There is a powerful likelihood that as numerous 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 specialists even propose a minimum distance of 10 miles in between outside marijuana fields to steer clear of cross-pollination. Marijuana pollen can attain even additional than that, but the danger is drastically lowered. Marijuana pollination is an critical component 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 frequently restricted to smaller-batch breeding by government cultivation limitations.


If a female marijuana plant gets pollinated, it stops expanding 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 expanding flowers.

Sexing Marijuana Plants

In order to figure out the sex of your marijuana plant, you will require to spend close consideration 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 principal stem Growers ought to 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 smaller, brief stem, and staminate primordia (smaller sacs) are expanding in between the nodes, it is possibly a male plant.
  • If pistillate primordia (two fuzzy white hairs) are expanding in between the nodes and the calyx is not raised on a smaller brief stem, it is a female plant.


Growers can get a fantastic thought of whether or not a plant is male or female earlier in the flowering cycle, even with out seeing the reproductive organs. If seeds of the identical strain are planted at the identical time, the distinction in sex will normally 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 prime than males (exactly where flowers will kind).


As you develop far more plants, you will understand to figure out the sex of your plants for the duration of the vegetative stage of development. Novice growers may perhaps take a couple of weeks longer to figure out the sex of the plant. You ought to be checking the nodes just about every day for calyxes expanding from the stipules. At the incredibly most current, plants will show their sex two or 3 weeks right after the light schedule is switched to 12 hours of light and 12 hours of darkness each and every day.

Removing Male Plants

Eliminate male marijuana plants as quickly as you figure out their sex. Male marijuana plants generate a scant quantity of flowers with incredibly low THC levels. Nevertheless, there are numerous fantastic utilizes for male cannabis plants. As an alternative of discarding your male plants, right here are a couple of techniques to make the most of them:


  • Breed new genetics by pollinating choose 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 less difficult the far more occasions you do it. At initial, you may perhaps have difficulty identifying the distinct qualities of the cannabis plant’s male and female reproductive organs, but every day observation aids you catch these male plants early.
