Pollination of your female cannabis plants will make them produce seeds and spend less energy on producing quality buds. But when you recognise the signs of pollination early, you can avoid putting time and resources into a poor harvest.
HOW TO TELL THAT A FEMALE PLANT HAS BEEN POLLINATED
The typical cannabis grower normally doesn’t have a reason to keep males, and will want to get rid of them as soon as they are spotted. Cannabis breeders, on the other hand, may want to keep males along with their crop of female plants. In such cases, the breeder will normally separate the sexes to avoid any accidental pollination. They may grow females in one tent and males in another. When grown outdoors, such as in a garden, the males are often kept in the most remote corner of their growing area, as far from the females as possible. Even then, because of the wind carrying around the pollen, there is always some risk of accidental pollination.
Among the early signs that your female has been pollinated is that her bracts become larger. Bracts are small, leaf-like structures that protect the female’s reproductive parts. These are the sites from which the flowering buds appear. Do not confuse the bracts with calyxes.
A good test to see whether the bracts have swollen is to take a pair of tweezers, grab one bract, and open it up. If there is a seed inside, you have a pollinated plant.
From psychoactive cannabinoids to aromatic terpenes, cannabis features many traits that make it unique within the plant kingdom. However, the uniqueness of the plant doesn’t stop at the phytochemicals it produces.
Growers identify plant sex by identifying pre-flowers, which are small structures that form at the nodes during late vegetation.
MALE VS FEMALE CANNABIS: WHAT’S THE DIFFERENCE?
Male pre-flowers look like tiny green eggs or “balls”. These young pollen sacs will look smooth and won’t possess any fine hairs, or any distinct point. Later into the flowering stage, pollen sacs begin to form larger and denser clusters. They’ll become easy to identify with the naked eye by this point. However, pollen sacs usually begin to disperse their contents around 2–3 weeks after forming. Be sure to remove them from your space with haste if you don’t plan on crossing your plants.
The former features distinctly male and female reproductive organs. Upon close inspection, you’ll notice pollen sacs occupying some nodes, and female flowers residing at others. When the pollen sacs rupture, the pollen will displace into the flowers, and the plant will effectively breed with itself. From there, it’ll go to seed and produce the subsequent generation.
“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.
