Difference in male and female weed seeds

Can You Tell the Sex of Cannabis Seeds from Their Appearance

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?

Can you determine the sex of cannabis seeds?

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.

Unfortunately, there’s not much truth to any of these interpretations. It’s simply impossible to tell just by looking at them what the sex of any cannabis seed is. If it was that easy, feminized marijuana seeds would not be as popular as they are. People could simply buy regular seeds and look at them themselves.

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.

So where do all the myths from sexing cannabis seeds come from?

Common myths on identifying the sex of a cannabis seed

One of the biggest myths of sexing cannabis seeds comes from a popular chart online.

The chart states that one can determine the sex of a cannabis seed by just looking at them. Within the chart, five cannabis seeds are shown. Three of these are female and two are male, supposedly. This chart says to look for a crater at the bottom of the seed. It explains that females will have a depression that is perfectly round. While males will have a crater that is misshapen and not uniform. However, this is simply not true. The craters found in cannabis seeds have nothing to do with the sex of a seed.

This same chart states that females will also roll easily across a table or surface, while males will not. While it does say that a magnifying glass and pair of tweezers is needed to examine the seeds. neither of these tools will make it any easier to determine the sex of cannabis seeds.

While growers may not be able to determine the sex of a seed, does the environment have anything to do with it? This is something else that has been hotly contested online.

Environment determines sex debate

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.

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.

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.

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.

Growers know that hermaphrodite plants can be just as harmful to crops as male plants. Therefore, it’s very important that every grower understand how to sex marijuana plants. Particularly if they’re not using feminized marijuana seeds that will give them only females.

While it would be much easier for growers to be able to sex their cannabis seeds, the simple fact is that there’s no way to do it. However, sexing plants early on during their growth period is not only essential, it’s completely possible. Growers can even do it before their plants enter the flowering stage if needed. Then male plants can be removed and growers can enjoy a nice, full crop.

Female vs. Male Cannabis Plants: How They’re Similar (and Different)

The main difference between male and female cannabis plants is that male cannabis plants do not yield buds, whereas female cannabis plants do. This means that female plants produce usable cannabis (buds) and male plants do not. There are many other obvious as well as subtler differences between male and female cannabis plants that can affect a cultivator’s crop.

Learn how male and female cannabis plants differ, how to tell them apart and whether or not you should grow them together.

What Are Female Cannabis Plants?

Female cannabis plants are the most sought after plants for most cannabis cultivators. They contain the prized bud that comprises all cannabis products, whether smokable, topical or otherwise. Female cannabis plants also contain the lion’s share of tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis. Male plants, in contrast, contain only trace amounts of THC.

The output of female cannabis plants is far more potent than that of male plants. While male plants can be used on occasion to make concentrate products like hash, female plants are widely preferred for this purpose. The coarse, tough hemp material derived from female cannabis plants is also useful for making rope and other products that require a strong fiber.

What Are Male Cannabis Plants?

Male cannabis plants grow pollen sacs rather than buds. They pollinate female plants with their pollen sacs. Cannabis grown from male plants is not usable, as it contains no “bud.” Male cannabis plants are essential in breeding programs and provide 50% of the genetic material that the seeds inherit. This is why, for breeders, strong fathers are as sought after as strong mothers. Male cannabis plants also tend to contain more phytocannabinoids on their leaves. Male cannabis plants with particularly high cannabinoid concentrations in their leaves combined with strong roots can become key parts of a breeding program.

In addition, male cannabis plants are useful for making hemp fiber, especially for clothing. The hemp material of male plants is softer than that of female plants, making it desirable for shirts, tablecloths or bed sheets. Finally, male cannabis plants are also effective at keeping harmful pests away.

How to Tell Male and Female Cannabis Plants Apart

Determining the sex of a marijuana plant is a visual process that you can begin early in the plant’s growth cycle. During the first four weeks of growth, you may be able to observe pollen sacs on the male and stigma or “pre-flowers” on the female. By the sixth week of growth, you will be able to clearly distinguish between male and female cannabis plants. The pollen sacs and pre-flowers will be in full view by this point, allowing you to pinpoint male or female.

In rare instances, you may observe a cannabis plant with both male and female reproductive organs. These hermaphroditic plants often develop due to environmental stressors including inhospitable weather and nutritional deficiencies. Hermaphrodites are distinguishable by sets of pollen sacs and pre-flowers. A healthy marijuana plant grown in optimal conditions will not turn hermaphroditic.

There are other clear physical characteristics that will help you tell male and female cannabis plants apart at any stage.

Characteristics of Male Plants

Look for these physical traits in a male cannabis plant:

  • Thick, sturdy stalks
  • Sparse leaves
  • Taller than female plants
  • Pollen sacs that form green and white flowers

Characteristics of Female Plants

Look for these physical traits in a female cannabis plant:

  • Slender stalks
  • Abundant leaves
  • Fine translucent hairs in white or orange
  • V-shaped pistils with protective layer (calyx)
  • Shorter than male plants
  • Resinous buds

Growing Male and Female Plants

The first principle of growing male and female cannabis plants is to keep them apart. Male cannabis plants can overtake a garden and drain female plants of vital energy. Specifically, male plants may over-pollinate the females, which will stop or slow bud development and severely reduce your yield.

Generally, male cannabis plants are less desirable than female ones. So, you will want to keep emale cannabis plants in your growing medium. If you are starting a breeding program, you will definitely need both male and female cannabis plants. But even in a breeding program, you need to keep your male and female plants apart.

Frequently Asked Questions

Do male or female weed plants grow faster?

Male weed plants tend to grow at a much faster rate than female weed plants. Fourteen days into the growth cycle, male plants will already be taller than female plants. In addition, male cannabis plants will start the flowering stage approximately 30 days before their female counterparts.

What’s the difference between male and female weed seeds?

Weed seeds that grow into female plants produce more THC compared to their male counterparts. Furthermore, female cannabis plants produce flowers while male cannabis plants produce tiny buds that resemble balls. V-shaped pistils will also appear on female cannabis seeds at the beginning of the flowering stage, but there are no such structures on male seeds. Finally, there are fine white and orange hairs present on female weed seeds but not on male ones.

Can male and female weed plants grow together?

While the plants technically can grow alongside one another, in general, you should not grow male and female weed plants together. Separate your male and female cannabis plants if you want to harvest buds from the females. This does not mean that male plants are useless; indeed, male cannabis plants can be an important part of a cultivator’s crop but should be mostly kept separate from females to allow the females room and energy to grow.

The Difference Between Male and Female Weed Plants

Cannabis plants have evolved enormously over the past couple of decades, mainly thanks to human kind. We’ve spent years combining different species from all over the planet. Every strain has its own specific characteristics, such as structure, type of buds, flavor and effects. When you combine male and female weed plants that are different strains, the new creation takes on characteristics from both, allowing us to create totally new plants.

One of the biggest achievements has been the appearance of feminized plants; after years and years of work, cannabis seeds can be created to have a 99% chance to be female. You need to know how to tell male from female plants when growing regular seeds, as you’ll only get actual psychoactive weed from the female flowers. Male plants pollinate female plants, which fills their flowers up with seeds so if you’re looking to make the most of your plants you’ll want to keep them away from each other. Hopefully we can help you to tell the difference between male and female weed plants by the end of this article; it’s not that hard, but if it’s not explained correctly it can be a bit confusing.

What’s the difference between male and female weed plants?

Male Cannabis

Male plants essentially produce pollen which is needed for cannabis plants to naturally reproduce; seeds occur when there are male plants in the mix. If you want to make your own seeds you will need a male plant However, if you’re growing regular plants and want to harvest flowers, we recommend getting rid of any males as soon as possible. You won’t be able to tell them apart until they begin to flower, which is when plants begin to show their sex. Male weed plants grow “balls” that open up to let their pollen out, ending up looking like a small bunch of flowers. You’ll need to get rid of them way before this happens. If they manage to release their pollen it’ll be too late. They can take up to three weeks to burst. If you’re still not sure how to tell them apart, male flowers do not have any pistils on them at all.

Female Cannabis

Female plants are basically what everyone is after when growing cannabis, as these are the ones that make buds, which is the part of the plant that contains the most THC. With just one male plant and a minuscule amount of pollen, your plants might end up filling their flowers with seeds. If you have male and female plants in the same growing area, the buds grown there will only produce seeds so you won’t be able to smoke any of it. You can tell females apart due to the fact that their flowers don’t fully close, they’re actually quite open and they produce little hairs called pistils. They’re incredibly easy to recognize, as the first thing they produce are their pistils, which male plants do not have at all.

Hermaphrodite Cannabis

Hermaphrodites are a type of plant that contains both male and female flowers, so they will produce buds but they will also pollinate those buds and the rest of your plants. Plants may naturally become hermaphrodites or be turned into one due to stress. Both female and male plants can turn. Thai strains are more genetically inclined to become hermaphrodites, although any strain can turn when stressed enough. There are many factors that can stress out your plants and end up turning them, such as extra light when they’re supposed to be in the night cycle, too much or not enough water, certain insects or pathogens, watering with cold water, or even a badly done transplant. Hermaphrodites aren’t the best type of plants to keep around, as they can produce buds but it’s definitely a risk because they might pollinate the rest of your plants. We recommend getting rid of them; it’s not worth it just for a little bit more weed.

It may seem confusing, but it really isn’t hard to tell male and female weed plants apart; they are quite different. Planting regular seeds has its benefits, as well as feminized has its inconveniences; you can get much larger yields with feminized plants as you’re guaranteed no male plants. Although, keep in mind that feminized seeds haven’t been through a 100% natural process to become female, which may affect the quality of your weed. This is why many cannabis connoisseurs haven’t made the leap from regular to feminized yet; they prefer to harvest slightly less yield that’s more potent and delicious.

However, feminized strains are a great option for rookie growers. Some seed banks, such as Nirvana seeds, Seedsman, Barney’s Farm, Ministry of Cannabis, Exotic Seeds or GB Strains offer amazing and affordable seeds that will provide fantastic results.
