Cannabis plants show their sex by what grows in between their nodes, where leaves and branches extend from the stalk. Pollen sacs will develop on a male plant to spread seeds and stigma will develop on a female to catch pollen. You can see these differences weeks before they actually start serving their purposes in the reproduction cycle. These are known as “pre-flowers.”
Mycorrhizae, a beneficial fungus, can be added to soil to improve root systems.
Sugar leaves are the small, resin-coated leaves that buds form around. Sugar leaves are usually saved as “trim” during harvest and can be used for pre-rolls, extracts, and other cannabis products.
Stigma and pistil
The cannabis plant has several structures, many of which we can find on any ordinary flowering plant species. Cannabis grows on long skinny stems with its large, iconic fan leaves extending out from areas called nodes.
The stigmas of the pistil begin with a white coloration and progressively darken to yellow, orange, red, or brown over the course of the plant’s maturation. They play an important role in reproduction, but stigmas bring very little to the flower’s potency and taste.

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.
Additionally, every long-time grower will tell you that clones degrade over time.
CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.
What are autoflowering cannabis seeds?
Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.
It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.
With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.
Young plants exposed to an 18-6 day-night photoperiod increases the chance of females. The chance increases further when the day length is reduced to 16 hours. To maximize the possibility, reduce the day period to 14.5 hours of light.
Statistically, cannabis produces more male plants than females. Using these techniques can increase the number of female plants grown from regular seeds. Make the most of your time, space, and precious dollars by boosting the number of females every grow.
USE COOL, BLUE LIGHT
Cannabis plants consume lots of nitrogen during the vegetation phase. Increasing nitrogen (N) slightly and reducing potassium (K) can increase the likelihood of females. A potassium-rich nutrient blend will boost the chances of males during the early development phase.
In the rush to get buds in the jar sooner, it is always tempting to expose plants to 24hrs of light during the vegetation cycle. The plants may grow larger sooner, but this increases the risks of males developing.
The other downside of 24hr light exposure during vegetation is poor root development and interrupted gas exchange in the rhizosphere. Root development occurs predominantly at night, and necessary oxygen exchange occurs more efficiently at this time too. Healthy roots mean healthy plants.
