why is my female cannabis plant producing seeds

“With hemp and cannabis, you h ave to walk your fields or monitor your plants every single day to ensure that there are no hermaphrodites or pollen on the plants, as it will affect the rest of your grow,” states Perlowin. “It is surprising how fast something can go wrong so it is important to watch closely. If you don’t find these plants, you could be jeopardizing not only your crops, but also those of other growers .”

Finally, swiftly remove any male flowers that appear. If the plant has very few male flowers, those flowers can be removed, but the plant will need to be watched closely. Plants with many male flowers should be eliminated entirely.

Cannabis plants are gendered, or for the botanically-inclined, dioecious. Female plants are particularly prized because they form buds that are rich in cannabinoid content. For most growers, maintaining a crop free of male plants is critical to ensuring that female buds are not pollinated.

How can you tell a male plant from a female plant?

Herming can occur when female plants experience conditions of environmental stress. “Female plants don’t actually turn male, they become hermaphrodites,” says Bruce Perlowin , CEO of Hemp, Inc . and seasoned cannabis cultivator. “You have a female plant that develops both reproductive parts so it can pollinate itself.” A hermaphroditic plant, by definition, contains both female and male sex organs .

Male plants can be identified most easily when they begin flowering. The flowers initially appear as a curved claw shape, which soon differentiates into a flower bud containing five radial segments. As the flowers develop, pollen sacs emerge that almost look similar to small bunches of grapes. Eventually, the sepals of the pollen sacs will open to release the pollen.

Other stressors that may incite female cannabis plants to become hermaphroditic include disruptions to the photoperiod, dramatic shifts in temperature, disease or pest infestations, the use of toxic pesticides, and physical damage from vigorous pruning.

Male plants won’t show hairs at these nodes, but will develop little sacs of pollen. These pollen sacs will look like little balls. These balls can appear on their own or in clusters, depending how far into the pre-flowering stage the plant is. At some later stage of growth, the pollen sacs will burst open, spilling the pollen and possibly pollinating your females.

There is a good reason why most growers keep male plants away from their ladies: Pollination from males causes the females to develop seeds. As a result, females focus their energy on seed production, rather than on growing you some fine-quality bud. This seedy and unfortunate final product can be avoided by implementing a few basic techniques.

WHAT TO DO WHEN YOUR FEMALES GET POLLINATED?

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.

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.

Obviously, no one wants to smoke seedy weed. When you grow cannabis and learn how to identify male plants and signs of pollination, you can remove these plants to save your remaining females. Likewise, recognising a pollinated female early allows you to start again before it’s too late, rather than finishing a grow that will only result in a poor-quality harvest.

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.

Your germination problems are also due to the fact that they were bagseed. It’s usually compressed and stored in a way that kills the seed. Seeds need to be stored in a cool, dry place to stay viable.

Bagseed plants are notorious for self-pollinating (hermiphrodite) late in flowering. Generally, the outdoor commercial weed isn’t pollinated with males (which are culled), but by hermi-females that are harder to see. This results in hermi-seeds. It’s very hard to find a reliable female from bagseed.

There’s nothing wrong with growing some bagseed. Hopefully you got some decent smoke and learned a lot. In the future, any seeds you buy from a breeder are going to seem like a breeze!
