male and female seeds

Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.

However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”

Tips for growing autoflower marijuana seeds

Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.

While environmental factors may not necessarily determine the sex of marijuana plants or cannabis seeds, it is known that certain environments can change the sex of a plant.

Of all the things that can trip a grower up, sexing marijuana plants may just be the trickiest. Sexing plants is so important because growers are typically after the female plants, that produce the huge THC covered buds. Or the medicinal relief that CBD strains can bring. With such opposite effects of male and female plants, it’s easy to see just how important sexing plants is. But what if growers didn’t have to wait to sex their plants? While it would certainly make life easier, is sexing cannabis seeds possible?

This will mostly happen when a plant is stressed by its environment. When this happens, the plant may think it’s going to die and as a result, will change itself into a hermaphrodite plant. By doing so, it will be able to self-pollinate itself and survive.

Common myths on identifying the sex of a cannabis seed

We know that determining the sex of cannabis seeds cannot be done. However, it’s unclear as to whether environmental factors have any place in determining the sex of marijuana plants.

This has been a question that has become a very hot topic online these days. After a quick search, growers can find multiple charts and explanations on how to sex cannabis seeds.

Research is carried out all the time to determine if a plant’s environment has anything to do with the sex it will turn out to be. And while there’s research stating that it does not, there’s just as much research stating that certain species do have their sex determined by the environment. This same research also states that using certain chemical treatments can also reverse the sex of a plant.

Typically, marijuana plants cannot be sexed until they have already begun to grow. Cannabis seeds will look somewhat identical and plants in the vegetative stage will also look identical,. As the plants move into their flowering stage, they will start to show very clear signs as to what sex they are. While it would be much more convenient for growers to be able to determine sex before this point. The sad truth is that it’s just not possible.

The ability to determine plant sex as early as possible is a critical skill for cannabis growers. Know as “Sexing Cannabis”, as you develop this eye for identifying plant sex, you will be able to prevent any accidental pollination.

Male plants, in contrast, don’t produce flowers. This makes them less valuable for growers seeking only buds. However, they do produce pollen sacs. These small vessels create the genetic material required to fertilise female flowers and create hybrids. This makes the males extremely important for breeding new cannabis strains.

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.

IDENTIFYING EARLY SIGNS OF MALE PLANT

“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.

Hermaphrodite cannabis plants come in two different forms: true hermaphrodites and “bananas”.

Several factors can cause female plants to start to develop pollen sacs—or exposed stamens—alongside their flowers. This trait means that plants don’t need to rely on a nearby male to burst their sacs and fertilise them. As we’ll discuss in a bit, this is actually a savvy survival mechanism and a display of nature’s genius. However, hermaphrodites aren’t desirable in the grow room or garden. Now, let’s discuss both types and how to avoid the issues they cause.

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.
