do male or female marijuana plants produce seeds

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.

What is herming, and why does it happen?

The sex of a plant is determined by its genetics before germination even begins. With the sex genetically encoded, there is no way to make a male plant female, or a female plant male. There are techniques that can be used, however, to encourage a male plant to display female characteristics. These techniques require the use of chemicals, such as ethylene , to prompt a hormonal response from the plant.

Elevated levels of female hormones in male cannabis plants can trigger female flowering development. The technique is more effective when applied to male plants that have not yet formed mature flowers. It’s also vital to bear in mind that many male marijuana plants are hermaphroditic plants, and distinguishing true males can be very difficult.

“When you see a pollen sac, you will know that a female plant is turning male,” says Perlowin. “Oftentimes, you can tell before the pollen sack becomes a problem. You should examine the plant from the very bottom of the plant to the top. It is easy to spot when the pollen sacs are at the top of the plant, but be sure to examine if there are pollen sacs at the bottom.” Male plants additionally grow taller than female plants as they mature and have thicker stems and fewer leaves.

Female cannabis plants are the main focus of casual growers looking to harvest a personal stash. But, depending on their genetics, female plants can look drastically different from one another. Some remain small, producing dense canopies and significant lateral growth. Others grow in excess of 3m, produce massive harvests, and look more like trees than regular garden plants.

Even if you have all of these bases covered, plants can still pollinate themselves due to poor genetics. Plants with a bad genetic history and too much genetic variation are prone to becoming hermaphrodites. For this reason, it’s important to shop with reputable companies that offer high-quality seeds with stable genetics.

HERMAPHRODITES: WHEN CANNABIS PLANTS BECOME MONOECIOUS

Growers identify plant sex by identifying pre-flowers, which are small structures that form at the nodes during late vegetation.

The ability to determine plant sex as early as possible is a critical skill for cannabis growers. As you develop this eye for identifying plant sex, you will be able to prevent any accidental pollination.

“Banana” hermaphrodites get their name from their physical characteristics. Instead of producing separate organs, they develop a bare pollen-producing stamen within the female flower. This naked appendage drops pollen directly onto buds to ensure self-reproduction. These stamens share a similar shape and colour to a certain tropical fruit, hence their name.
