do female marijuana plants have seeds

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.

HOW TO TELL THAT A FEMALE PLANT HAS BEEN POLLINATED

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.

Pollination requires the presence of males or intersex (hermaphrodite) plants, which are females that will also produce pollen. The first thing you want to do to keep the risk of pollination low is to remove as many males or “hermies” as as you can. Especially during the first three weeks of flowering, it’s important to frequently check for possible male specimens in your garden.

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.

What’s most important, whether you get feminized seeds or not, is to get your seeds from a breeder who has a reputation for producing quality genetics. That is the best thing you can do for any strain to ensure a smooth grow. With a great breeder, you have a very low risk of running into any sex or gender problems.

Good feminized seeds should produce only 100% female plants, with no hermies or male plants. So starting with feminized cannabis seeds lets you make the most efficient use of your grow space. You don’t have to worry about identifying male plants and throwing them away before they pollinate your female plants. With good feminized seeds, you know that if you’re growing 10 plants, all 10 of them will make buds, and that makes it easier to plan out your grow ahead of time.

All plants produce buds

Every plant grown from feminized seeds will produce the buds we know and love. This plant was grown from feminized Swiss Cheese seeds.

This hermie is growing both male and female flowers. Can this be caused by feminized seeds?

What Are Feminized Cannabis Seeds? These seeds all grow up to be female plants. That means every plant produces buds. With “regular” or unfeminized seeds, about half the plants will turn out to be male, which don’t produce buds. They can also pollinate your female plants (causing seedy buds). Therefore most growers will remove male plants from the grow room as soon as they’re identified. Learn more about male vs female plants. Feminized seeds let you plan your grow more effectively because you don’t have to throw half the plants away once they start flowering.

Is it True that Feminized Seeds Sometimes Cause Hermies? Yes!

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.

Cannabis, like those who love it, doesn’t always stick to the rules, though. Sometimes, this dioecious plant species goes against the grain and develops both male and female reproductive organs. These specimens are known as hermaphrodites. Either genetic or environmental factors, or both, can cause plants to develop this unusual trait. Having both buds and pollen sacs, they end up developing the ability to pollinate and reproduce with themselves.

IDENTIFYING FEMALE CANNABIS PLANTS

Female pre-flowers also develop at the nodes. You can distinguish them based on one obvious visual characteristic: hairs. Female pre-flowers feature tear-drop shaped calyxes with small hairs protruding from the tip. These small hairs, known as pistils, are the sex organs of female cannabis flowers.

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.

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.
