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.
A guide to differentiating between male, female, and hermaphrodite cannabis 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.
IDENTIFYING HERMAPHRODITE CANNABIS PLANTS
It should also be noted that male pollen sacs and female flowers develop at the same point on the plant. Both structures emerge from nodes, the point at which branches meet the main stem. So, when you see buds starting to form on some plants, start looking for pollen sacs too.
“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.
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.
To avoid this issue, try to maintain a stable environment in your grow room. Use a thermo-hygrometer to monitor temperature and humidity, keep your light schedule strict, and ensure your plants get all the nutrients they require.
Additionally, every long-time grower will tell you that clones degrade over time.
So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.
What are autoflowering cannabis seeds?
Within a week or so you should see a seedling begin to grow from the soil.
Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.
For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.
Pre-Flowers usually reveal the gender around week 6 from seed
This pre-flower doesn’t have a pistil sticking out at first, but the shape helps tell you it’s a female plant. If you’re not sure about gender after spotting a pre-flower, it’s a good idea to wait and see for a little while, just to see if a white hair appears (which means it’s definitely a girl)
Regular Marijuana plants reveal their gender in two situations:
Most growers prefer to grow female plants, as only female plant produce buds/flowers.
A vigilant grower can carefully watch their plants and remove males when they develop the first signs of pollen sacs.
