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.
Spotting male cannabis plants and pollinated females early can save you from investing further time and effort into an entire growing season that will be for naught. Most of the time, the best course of action is to get rid of the males along with your pollinated ladies and just start a new grow.
HOW TO AVOID POLLINATION OF YOUR FEMALE PLANTS
To determine the sex of your cannabis plants, you will have to wait until the pre-flowering stage when plants begin to put their energy into reproduction. Female cannabis plants show their gender signs later than males. At the location where they will soon grow their buds (the nodes between the stalk and the stem), females will show wispy white hairs.
Another indication of pollination can be the colour of her pistil hairs. When a female has been pollinated, the previously white hairs will soon shrivel and become darker.
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.
Breeder choice is important!
Are your cannabis bagseeds viable? Viable, good seeds usually appear either dark and striped or solid gray/beige.
It’s no good if your “female” plants start growing male flowers or parts of male flowers. That can cause seedy buds just like a male plant!
What Are Hermies? “Hermie” is short for “hermaphrodite.” Hermie cannabis plants usually look like normal female plants for the most part, but they also grow some male parts that produce pollen. This causes seedy buds just like pollen from male plants. Hermies are to be avoided! Read the full tutorial on hermies.
Unfortunately, hermies can be a lot easier to miss than a male plant since it may just be a small part of the plant that’s affected. A male plant makes itself known at the beginning of the flowering stage, but a hermie plant may grow only buds except for just one or two tiny pollen sacs. A few yellow hermie bananas hidden in the buds can also produce pollen. Any type of male flower part that grows in your garden can add seeds to your buds, and hermies are some of the worst offenders.
Hermies can be caused by many things, including…
What’s the matter with a few seeds?
Cannabis growers and breeders use this trait to their advantage, since it allows them to separate male and female plants. This enables them to prevent the flowers from becoming fertilised and going to seed, which results in better quality flowers, known as sinsemilla.
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.
MALE VS FEMALE CANNABIS: WHAT’S THE DIFFERENCE?
Let’s take a deeper look into male and female cannabis plants. From there, we’ll see what causes some specimens to develop both male and female reproductive organs.
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.
During the early flowering stage, take a stroll around your grow room or garden with a magnifying glass or jeweller’s loupe. Inspect a few nodes on each plant to see how far along into the flowering process they are. At this stage, you won’t see any obvious flowers or pollen sacs. Instead, you’re looking for young pre-flowers. Although these tiny structures look similar, they have distinct features that allow growers to tell them apart.
