When growing strains that are sensitive to stress, growers run a risk of their cannabis plants developing hermaphroditic traits – like the well-known Original Glue (Gorilla Glue #4). In our online seeds catalogue, you’ll find certain strains that are particularly resistant to stress.
TIP: If you want to try and create your own unique strains, you can learn more about growing regular seeds in this blog.
When pollen from a male cannabis plant reaches a female cannabis flower, the female flower will start producing seeds with traits from both plants involved. That’s great for growers that like crossbreeding strains and develop their own cannabis varieties. But if you’re growing for your personal consumption, you might want to avoid pollination. Not only do seeds add a harsh taste to your smoke. Producing them also takes a lot of energy from the plant. Costly energy that should rather be put into the development of cannabinoids like THC and CBD.
How To Prevent Stress From Turning Female Cannabis Into Hermaphrodites
Male Cannabis Plants form small ball-shaped pollen sacs on their nodes
So even if you use feminized seeds, it is advised to keep a close eye and determine the sex of the plant as soon as you can. As there’s always a small chance at finding a male plant in your garden which could screw up your harvest, or for the plant to turn from female to hermaphrodite and develop both sexes on one cannabis plant; as we’ll explain later on.
You don’t have to be an expert on the plant to at some point have encountered the term ‘feminized’ in relation to cannabis seeds. As the name suggests, this means cannabis plants can be either female or male and in some cases have both sexes. This is what you need to know to spot Male, Female and Hermaphrodite cannabis plants in your garden:
Hermaphrodite cannabis plants develop both female and male reproductive organs
Within a matter of weeks, these small pre-flowers swell into dense nuggets and begin churning out cannabinoid and terpene-rich resin. Since you the removed males and prevented pollination, your flowers will continuously produce resin until the end of the growing cycle.
Despite their differences, all female plants share one thing in common: they produce flowers. These flowers, colloquially known as buds, possess small glandular structures called trichomes that produce cannabinoids such as THC and CBD.
These protruding structures are designed to capture pollen, which leads to fertilisation. They stick out away from the flower to capture pollen from the air, and to await being brushed up against by pollen-covered insects.
IDENTIFYING HERMAPHRODITE CANNABIS PLANTS
“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.
When you grow cannabis plants, they will either turn out as females, males, or hermaphrodites, meaning a hybrid of the two sexes. Knowing the difference between the three is vital to maintaining a strong growing operation, whether you’re planning on crossbreeding strains, maximising the yield of your female plants, or studying each of the types.
See, the vast majority of plant species are monoecious, a term meaning they possess both male and female reproductive organs. These include edible plants, such as corn and squashes, that can readily fertilise their own flowers using their own pollen.
Of course, growers want to avoid this phenomenon if they’re aiming for the best flowers possible. We’ll dive deeper into what causes hermaphroditism and how to avoid it below.
In the past this was not a problem, because cannabis was used for making fibres and the seeds were eaten, so every plant was valid. Then they started smoking the flowers after removing the seeds, as well as producing hashish centuries later, and they soon realized that female plants were much better for these purposes, or that they barely showed any male flowers.
It was the human hand that began to isolate the best females for its own use, and by selection and crossing the dioecious traits were fixed in some pure varieties. From the best stable Landraces came the first hybrids, and from them most of the polyhybrids we know nowadays. The vast majority of cannabis seeds nowadays are of well-defined sex, but there are still genetics that can show hermaphroditism and this is what we will see here. What is a hermaphrodite cannabis plant and what can we do with it?
📲 Meaning of Hermaphrodite
Sometimes we find some seeds among the whole harvest of a plant, which usually come from self-pollination, they are the so-called S1. This happens when a little banana comes out and fertilizes a small area of a bud, so only a few seeds come out, sometimes only one. These seeds are feminized and very similar to the plant from which they come out, they always come out female, but they are always prone to produce some male flower between their buds as well.
The definition of hermaphrodite in marijuana plants means specimens containing both sexes in the same flower. This process is also called Monoceia. This can be a big problem if you want to smoke the buds, because male flowers normally pollinate female flowers and your buds will contain seeds. So, is hermaphroditism bad? It is for us, although we have to understand that sometimes it is a positive reaction that the plant shows on certain situations.
