Have you ever wondered how to tell if your pot plant is male or female? It’s actually quite easy, once you know what to look for. In this article, we’ll show you how to identify the sex of your plants so that you can make informed decisions about your grow. We will provide you with clear instructions and helpful tips that will enable you to distinguish between male and female pot plants with confidence. Whether you are a seasoned grower or just starting out, this guide will provide valuable insights into this important aspect of cannabis cultivation.
The first step in determining the sex of your pot plant is to look at the leaves. Male plants typically have leaves with five or seven leaflets, while female plants usually have leaves with nine or eleven leaflets. The leaflets on male plants are also narrower and more pointed than the leaflets on female plants. However, it is important to wait for the plant to reach maturity in order to make a more accurate judgment based on the number of leaflets, as young plants may display atypical leaf characteristics.
Another way to tell the sex of your pot plant is to look at the flowers. Male plants produce pollen sacs, which are small, round structures located at the base of the flowers. Female plants produce pistils, which are long, thin structures that are located in the center of the flowers. If you see pollen sacs, then your plant is male. If you see pistils, then your plant is female. It is crucial to note that the development of flowers, commonly referred to as “pre-flowers,” initiates the definitive stage for sex identification. Prior to this stage, it is challenging to distinguish between male and female plants solely based on vegetative characteristics.
Observe the Cotyledons
A cotyledon is a seed leaf that contains the embryo of the plant. In male cannabis plants, the cotyledons are long and narrow, while in female plants, the cotyledons are short and round. Take a close look at the first pair of true leaves that emerge after the cotyledons.
Male cannabis plants will typically produce pointed leaves with 5 to 7 thin leaflets, while female plants will produce rounded leaves with 7 to 9 wider leaflets. The leaves of male plants tend to be longer and narrower than those of female plants.
Male cannabis plants produce smaller, rounder, and less resinous buds compared to female plants. The buds of male plants have a more compact and dense structure, and they often contain fewer trichomes.

Note the Internodal Spacing
Another distinctive feature of male pot plants is their internodal spacing. Internodes refer to the stem sections between each leaf node. In male plants, the internodes tend to be longer and more pronounced, resulting in a more stretched-out appearance compared to female plants. This elongation of the internodes is primarily due to the higher presence of auxin, a plant hormone that influences stem growth.
Internodal Spacing Table for Male vs. Female Pot Plants
| Plant Sex | Internodal Spacing |
|---|---|
| Male | Longer, more pronounced |
| Female | Shorter, more compact |
The elongated internodal spacing in male plants allows for better pollen dispersal, as the flowers are held further apart from each other. The reduced internodal spacing in female plants, on the other hand, allows for a more concentrated distribution of bud sites, contributing to the denser and more compact flower clusters that are sought after for their high resin production.
Evaluate the Odor
During the flowering stage, male cannabis plants release a distinct odor that can help you identify them. This odor is often described as being skunky, pungent, or acrid. It is caused by the production of volatile terpenes, which are aromatic compounds that give plants their characteristic scents. Male plants produce significantly more terpenes than female plants, which is why their odor is more noticeable.
To evaluate the odor of your cannabis plants, gently rub or crush a small leaf or bud between your fingers. If you detect a strong, pungent odor, it is likely a male plant.
Here is a table summarizing the odor differences between male and female cannabis plants:
| Plant Type | Odor |
|---|---|
| Male | Strong, pungent, skunky |
| Female | Mild, less noticeable |
It is important to note that the odor of cannabis plants can vary depending on the strain and environmental factors. However, in general, male plants will have a more pronounced and unpleasant odor than female plants.
Perform a Touch Test
Step 8: Determine the sex of your pot plants by performing a touch test:
Materials you’ll need:
| Male Plants | Female Plants |
|---|---|
| Small sacs (pollen sacs) | Pistils (white hairs) |
| Pollen | Seeds |
| Become visible around 3-4 weeks | Become visible around 4-6 weeks |
Instructions:
- Inspect the nodes (where the branches meet the main stem) of your pot plants.
- Gently feel around the nodes for small, round sacs.
- If you feel sacs, they are likely pollen sacs, indicating a male plant.
- If you don’t feel any sacs, the plant is likely female.
- Repeat this process for all your pot plants to determine their sex.
Note: It’s important to perform the touch test regularly, especially during the early stages of growth. This will allow you to identify and remove male plants promptly before they produce pollen and fertilize female plants, leading to unwanted seeds.
Use a Jeweler’s Loupe for Magnification
A jeweler’s loupe is a small, handheld magnifying glass that can be used to view small objects in great detail. When used to inspect cannabis plants, a jeweler’s loupe can help you identify male and female plants by examining the pre-flowers that develop at the nodes where the branches meet the main stem.
How to Use a Jeweler’s Loupe to Identify Male Pot Plants
- Gather your materials. You will need a jeweler’s loupe with a magnification of at least 10x, a pair of tweezers, and a white piece of paper.
- Locate the pre-flowers. The pre-flowers will develop at the nodes where the branches meet the main stem. They will be small, green bumps.
- Remove a pre-flower. Use the tweezers to gently remove a pre-flower from the plant.
- Place the pre-flower on the white paper. This will help you to see the pre-flower more clearly.
- Examine the pre-flower with the jeweler’s loupe. Look for the following characteristics:
- Male pre-flowers: Male pre-flowers will have five sepals, which are the small, green leaves that surround the flower. They will also have stamens, which are the long, thin structures that produce pollen.
- Female pre-flowers: Female pre-flowers will have two sepals and a pistil, which is the small, sticky structure that receives the pollen.
How to Tell Male Pot Plants
- Male pre-flowers: Male pre-flowers will have five sepals, which are the small, green leaves that surround the flower. They will also have stamens, which are the long, thin structures that produce pollen.
- Female pre-flowers: Female pre-flowers will have two sepals and a pistil, which is the small, sticky structure that receives the pollen.
To tell male pot plants from female pot plants, you need to look at the pre-flowers that form at the nodes where the branches meet the main stem. Pre-flowers are small, immature flowers that will eventually develop into full-fledged flowers. In male plants, the pre-flowers will have small, round pollen sacs. In female plants, the pre-flowers will have small, white pistils. If you see pollen sacs on your plant, then it is a male plant. If you see pistils on your plant, then it is a female plant.

How can you tell the difference between male and female pot plants?
You can tell the difference between male and female pot plants by looking at the pre-flowers that form at the nodes where the branches meet the main stem. Male plants will have small, round pollen sacs, while female plants will have small, white pistils.
What happens if you grow a male pot plant?
If you grow a male pot plant, it will pollinate the female plants in your grow room. This will cause the female plants to produce seeds, which will reduce the potency of your buds. It is important to remove male plants from your grow room as soon as possible to prevent them from pollinating the female plants.
What should I do with a male pot plant?
If you find a male pot plant in your grow room, you should remove it immediately. You can compost the plant or throw it away. Do not attempt to smoke the buds from a male plant, as they will not produce any psychoactive effects.
