cannabis plant produce seeds

Females are the prizes of cannabis plants—they are the ones that grow the buds that we all know and love. Anytime you see a picture of a cannabis plant with buds, you are looking at a female plant.

The roots grow down from the main stalk of the plant into the soil. When growing from a seed, the main root is called the “taproot.” Roots are the lifelines of a cannabis plant, pulling water and oxygen into the plant so it can grow healthy and strong.

Males are important in the breeding process, but that is generally best left to expert breeders. When pollinating females, males provide half of the genetic makeup inherited by seeds.

Mycorrhizae, a beneficial fungus, can be added to soil to improve root systems.

Despite their minute size, it’s hard to miss the blanket of crystal resin on a cannabis bud. This resin is secreted through translucent, mushroom-shaped glands on the leaves, stems, and calyxes.

Also known as “buds,” the flowers of a cannabis plant are the fruits of your labor. They contain the cannabinoids and terpenes that get you high or offer health benefits. Flowers only grow on female cannabis plants and must be dried before consumption.

Fan leaves are the large, iconic leaves of the cannabis plant. They capture light for the plant and typically have little-to-no resin and are usually discarded when trimming.

Author Robert Connell Clarke’s book Marijuana Botany An Advanced Study: The Propagation and Breeding of Distinctive Cannabis presents clear instructions for differentiating male and female plants. The gender of a cannabis plant is located at the nodes along the main stem.

Herming can occur when female plants experience conditions of environmental stress. “Female plants don’t actually turn male, they become hermaphrodites,” says Bruce Perlowin , CEO of Hemp, Inc . and seasoned cannabis cultivator. “You have a female plant that develops both reproductive parts so it can pollinate itself.” A hermaphroditic plant, by definition, contains both female and male sex organs .

Female plants usually take several days longer than males to develop pistils or female sexual organs. The pistils look like small green seed pods and have white v-shaped stigmas, or thin hairs, which extend from them. Female plants are generally shorter, denser in foliage, and broader than their male counterparts.

“With hemp and cannabis, you h ave to walk your fields or monitor your plants every single day to ensure that there are no hermaphrodites or pollen on the plants, as it will affect the rest of your grow,” states Perlowin. “It is surprising how fast something can go wrong so it is important to watch closely. If you don’t find these plants, you could be jeopardizing not only your crops, but also those of other growers .”

The vast majority of cannabis growers cultivate the plant to produce sensimilla . Sensimilla refers to female cannabis buds that have not been pollinated by a male cannabis plant. Sensimilla is more potent than seeded cannabis as it contains greater concentrations of essential oils and psychoactive cannabinoids.

“Herming can also definitely be a genetic problem, but it is not cultivar-specific,” says Perlowin. “You can get the same cultivars from different seed companies, and they will yield different results.” Reputable breeders are more likely to competently sort and select seeds from genetically robust plants with desirable traits.
