Because of this, it’s important to look into the genetics of the male plants. Their shape, rate of growth, pest and mold resistance, and climate resilience can all be passed on to increase the quality of future generations.

However, cannabis is primarily cultivated for buds, not seeds, so the practice of growing sinsemilla, or “seedless” cannabis, is prevalent today: Females and males are grown separately, or males are even discarded, to prevent pollination. This allows female plants to focus their energies on bud production instead of seed production.
A cola, also called a “bud site,” refers to a cluster of buds that grow tightly together. While smaller colas occur along the budding sites of lower branches, the main cola—sometimes called the apical bud—forms at the top of the plant.
How to determine the sex of a marijuana plant
“Herming out,” as some call it, is something that generally happens when a plant becomes excessively stressed. Some stressors include:
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.
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.
Cannabis really stands out in its flowers—or buds—where unique and intricate formations occur: fiery orange hairs, sugary crystals, and chunky buds enveloped by tiny leaves.
You will only get a male cannabis plant is you grow from a non-feminized seed. In today’s world, if you get a clone from a trusted friend or local shop, they will always grow to be a female plant. Male and female plants can be easily identified in early flowering by looking for the following characteristics below:
When it comes to cannabis, female plants produce flowers (or buds) and males produce pollen. Unless you plan on breeding, male cannabis plants will release pollen into the growing area and produce unwanted seeds in nearby female flowers. Cannabis flowers with seeds are usually lower in potency and less desirable. Male plants in a flowering room should removed as soon as they are identified.
Male cannabis plants have stamens and female plants have calyxes. To the untrained eye, an early calyx and stamen can look quite similar. As the cannabis plant begins to mature, multiple stamens will begin to appear on the males and the females will have pistols emerge from their calyxes. Over time the stamens will fill with pollen and eventually open, releasing it into the growing environment. Once a plant shows clear male characteristics, it should be removed from the flowering area and potentially used for future breeding projects.
One of the biggest evolutions has been the appearance of feminized plants; after years and years of work, cannabis plants can be created to have a 99% chance to be female. You need to know how to tell male from female plants when growing regular seeds, as you’ll only get actual psychoactive weed from the female flowers. Male plants pollinate female plants, which fills their flowers up with seeds so if you’re looking to make the most of your plants you’ll want to keep them away from each other. Hopefully we can help you to tell the difference between male and female weed plants by the end of this article; it’s not that hard, but if it’s not explained correctly it can be a bit confusing.
What’s the difference between male and female weed plants?
Hermaphrodites are a type of plant that contains both male and female flowers, so they will produce buds but they will also pollinate those buds and the rest of your plants. Plants may naturally become hermaphrodites or be turned into one due to stress. Both female and male plants can turn. Thai strains are more genetically inclined to become hermaphrodites, although any strain can turn when stressed enough. There are many factors that can stress out your plants and end up turning them, such as extra light when they’re supposed to be in the night cycle, too much or not enough water, certain insects or pathogens, watering with cold water, or even a badly done transplant. Hermaphrodites aren’t the best type of plants to keep around, as they can produce buds but it’s definitely a risk because they might pollinate the rest of your plants. We recommend getting rid of them; it’s not worth it just for a little bit more weed.
Female plants are basically what everyone is after when growing cannabis, as these are the ones that make buds, which is the part of the plant that contains the most THC. With just one male plant and a miniscule amount of pollen, your plants might end up filling their flowers with seeds. If you have male and female plants in the same growing area, the buds grown there will only produce seeds so you won’t be able to smoke any of it. You can tell females apart due to the fact that their flowers don’t fully close, they’re actually quite open and they produce little hairs called pistils. They’re incredibly easy to recognize, as the first thing they produce are their pistils, which male plants do not have at all.
