Difference Between Male And Female Plants, Knowing how to tell the sex of your Marijuana plants is important as it is the female plants that offer us those delicious buds that once dried we can smoke.
The male plants are usually only used for one thing, to pollinate female plants, to obtain regular cannabis seeds.
We can easily find the sex of our plants in two ways, before the flowering stage or during the flowering stage. We will see how to distinguish between a male plant and a female plant very easily, without needing a magnifying glass/microscope using the naked eye and in less than half a minute.
It does not matter if your plants are outdoors (garden, terrace, field, guerrilla …) or indoors the technique is the same for all types of plants. Regardless of your cultivation technique.
How to know the sex of my Marijuana plants BEFORE the flowering stage
This may sound a bit strange to you, but the truth is that it is possible to know the sex of cannabis plants even before they begin to flower. This is due to the sexual maturity of the plants themselves, which, although they are not in bloom, show very marked patterns with which we can determine their sex.
In order to know the sex of a plant before the flowering stage, it must have reached sexual maturity. Marijuana plants mature sexually around the fifth week of life (since we germinated).
That is, from the fifth week of growth, it is possible to know if it is a male or female cannabis plant. Some varieties may take six or seven weeks, but usually, in the fifth week, they are mature.
Where To Look.
What we should do is look at the top of the plant, to the latest plant axis ( part of the stem where the plant branches from the main stem). Right at the newest ones is where we can determine the sex of our plant.
We should look just at the part of the node where the branch joins the stem, even if the branch is not yet fully developed. There we can observe the formation of a small preflower, which is the key to know if the plant is male or female. This formation is called pre-flower.
If there are two small white hairs, it is a female cannabis plant. If it is shaped like a hanging egg, it is a male cannabis plant.
In this photo, you can see perfectly what I mean:
Let’s see with a little more detail, keep in mind that the photo is enlarged, but in reality, they are very small pre-flowers. So although we do not need the help of a magnifying glass … we must be attentive to what What we see.
In the following image apart from seeing a pre-flower of a female plant. We can also see the parts of the pre-flowers. With the letter A shows the Calyx of the plant, with the letter B showing the white hairs called pistils and the letter C shows the Stipule:
Female Marijuana Pre-Flowers
Male Cannabis Pre-Flowers
As you can see, it is very easy to determine the sex of our plant during the growth stage. It will take us no more than half a minute to locate the pre-flowers and know what we have in our garden.
If you do not find pre-flowers, it is possible that your Marijuana plant has not yet matured sexually. Just wait another week or two and you will see the pre-flowers.
Here is another photo, for those who still have doubts. To the left of the photo, a plant with male pre-flowers, to the right of the image a plant with pre-female flowers:
How to know the sex of my Marijuana plants during the flowering stage
This is the safest and easiest way to know the sex of our Marijuana plants. During the flowering stage, the plant will begin to remove pre-flowers and flower gradually, regardless of whether it is an indoor or outdoor crop, or that your plant is automatic or standard …. This is the safest way to determine the sex of your plant.
Around two or three weeks after the beginning of flowering (outdoors when the days begin to shorten in mid-late late summer. Or Indoors when we change the light cycle to 12/12), we can see how the first flowers begin to develop.
This occurs in indica marijuana plants around the two to three-week mark, in sativa plants, it tends to take longer since the flowering cycle is much longer. You can see the different types of marijuana here (differences between indica and sativa)
Once they have shown the first flowers, we will know right away what it is. In the following pictures you can see how the male cannabis plants and the female Marijuana plants are, as well as their main differences:
Male Marijuana Plants
And now a few pictures of how the flowers and buds look of female cannabis plants. They are very easy to recognize, the more advanced the flowering, the more quantity and thicker we will see them.
Female Cannabis Plants
And with this we finish, the nice simple way to knowing the sex of your marijuana plant. Either during the growth stage or the flowering stage. Check out Cannabis Flowering Stage Week By Week
