First of all you need to know what type of seed to us… Amsterdam Seed Supply – Keen on growing but you want to know what Marijuana seeds are female? – Discrete order & shipment Make your first ‘cross’ a success by creating a structured breeding program with these 6 tips and a simple, 4-step program.

Pros and cons of each type of seed: regular, feminised, autoflowering and CBD-rich

In its natural state, the marijuana plant is dioecious, that is, there are male and female specimens that breed among each other to create new specimens. Regular seeds are seeds that produce both male and female plants, where the grower has no control over their sex.

Although in recent years the proportion of users who choose this type of seed has fallen considerably, regular marijuana seeds continue to be the preferred option for some old-school growers, who wish to respect the nature of the plant in all aspects and, of course, by those who wish to make their own seeds.


  • Breeding: Regular seeds make it possible to breed the plants making seeds with the males and females that emerge from a batch of regular seeds.


  • Limited yield: The problem with regular seeds is that you do not have any control over the sex of the plants, meaning that after a month and a half of caring for them you may find that you have to get rid of half of your plants because they are males, thus reducing by half the potential yield of the crop.

Feminised seeds

Feminised seeds emerged in the late 90s as a response to the need to grow seeds that guaranteed the development of female plants. At the beginning this type of seed produced cannabis plants with certain quality problems and instability, with plants that sometimes suffered from hermaphroditism. However, over the years feminised seeds have achieved extremely high levels of quality, as regards yield, effects or flavour, to the point that they have relegated regular seeds to a mere 10% market share.


  • Cost effectiveness: Feminised marijuana seeds guarantee 100% female crops. That is, all the effort and care you invest in the plants will be rewarded because there will be no male specimens to discard.


  • As they do not allow the development of male plants, feminised seeds are not the appropriate choice if your aim is to produce seeds.

Autoflowering seeds

After feminised seeds, starting in approximately 2008 autoflowering seeds, also known as automatic seeds, made their arrival. As the name indicates, they flower in a shorter period of time and require less care than regular or feminised seeds. Autoflowering marijuana seeds emerged as the ideal choice for less experienced growers, but as their quality parameters have gradually equalled their non-autoflowering cousins in aroma, flavour and effects, they have become a valid alternative for the most demanding growers. In case you were wondering, yes, the autoflowering seeds are also feminised.


  • Speed: Without a doubt, the big advantage of autoflowering seeds is the speed with which they develop. The flowering periods change depending on the variety, but with any automatic variety you know that in two and a half months tops your plants will be harvested.
  • Manageability: Although the differences in quality of autoflowering plants in comparison to the rest of the feminised plants are increasingly fewer, most of the automatic varieties are smaller in size, not only requiring simpler maintenance, but they are also ideal for discreet crops, on balconies or terraces. If your idea is to have a manageable marijuana plant, camouflaged among the flowers and pots on your terrace, autoflowering seeds are, without a doubt, your option.
  • Ease: Autoflowering seeds are, in general, easier to grow, both indoors and outdoors. In indoor gardens it is not necessary to change the photoperiod, as the plants themselves change from the growth period to the flowering period by themselves. That is, regardless of the hours of light they receive, they will develop buds.

  • Yield: As they are smaller in size, autoflowering cannabis seeds have the inconvenience of a smaller yield per plant.

CBD-rich seeds

You have probably heard a lot lately about CBD, the cannabinoid in vogue. CBD is present in some marijuana plants and, in addition to having many therapeutic qualities, it counteracts the psychoactive effects of THC. Therefore, CBD-rich varieties of marijuana cannot only help people who suffer from insomnia, stress or more serious conditions such as multiple sclerosis, but, in addition, it can enable a more sustainable recreational consumption of cannabis compatible with daily activities. As for its cultivation, you can find both feminised and autoflowering varieties rich in CBD.


Reduced psychoactive effect: As it acts as an antagonist of THC, CBD counteracts the psychoactive and side-effects of the former. To make a comparison with alcohol, a variety with high levels of THC would be like drinking spirits, while another rich in CBD would be like drinking a beer.

Therapeutic properties: CBD interacts with the human body’s endocannabinoid system, activating and stimulating our natural response to pain, anxiety, stress, etc. Scientific research has found that CBD can bring many benefits to our body including:

  • Reduction of nausea and vomiting
  • Suppression of convulsive activity
  • It combats psychosis disorders, and there have been studies and clinical trials which indicate that CBD can be effective for treating schizophrenia
  • It combats inflammatory disorders
  • It combats neurodegenerative disorders
  • It combats anxiety and depression disorders
  • Fewer side-effects: CBD counteracts the side-effects associated with THC, such as increased appetite, faster heart rate, poorer memory or an altered perception of time, among others.


A reduced psychoactive effect: what may be an advantage for some, can be an inconvenience for others. CBD causes the effects of marijuana to be less intense, much milder, and not everyone is interested in that milder effect.

What Marijuana Seeds Are Female?

As a rule of thumb, you cannot know what sex the Marijuana seeds are by just looking at them. Even Feminized Marijuana seeds are 99.99999% certain to be female. The only way you can find out what marijuana seeds are female is by germination. After two or three weeks, you will see the male or female flowers and this is the only way to know for sure what marijuana seeds are female.

You know what marijuana seeds are female, but why all the fuss?

Feminized marijuana seeds are the “easiest” seeds to grow after the Auto-flowering varieties. Feminized marijuana seeds mean that they are treated to make them female marijuana seeds (hence the name feminized) so that all the marijuana seeds can be used to get flowers. Breeders usually sell feminized marijuana seeds for their strains because they are easier to grow than regular female marijuana seeds and are too unstable to reproduce, although some people use female plants from feminized marijuana seeds to get cuttings, it is advisable that they use female from Regular marijuana seeds. It is recommendable to start growing with Feminized marijuana seeds, this will mean that the final plant won’t have any undesirable surprises like marijuana seeds reducing potency since there are only female marijuana plants.

6 Tips for Cannabis Breeding Success

Make your first ‘cross’ a success by creating a structured breeding program with these 6 tips and a simple, 4-step program.

Breeding programs for almost any plant can be as simple or as complex as you choose to make them. Fortunately, you can quickly and effectively develop your own breeding program, even if you are a beginner. All it takes is a sharp eye for positive traits that you’re interested in developing and an accurate record-keeping system to track the usable crosses you’ve made, as well as the parental lines (male and female) that you’ve used.

Cannabis is dioecious (meaning the species includes separate female and male plants) as opposed to monecious (which means that an individual plant can have both male and female flowers). You need both male and female plants to begin a breeding program. TIP: It is imperative that you separate males and females from the beginning, and keep them separated throughout the program to ensure that you don’t get unwanted contamination by pollen from male plants that you have not selected to cross.

So how do you select breeding parents or parental lines to begin with? While it is relatively easy to select the female line, it can be difficult to select male lines for the following reasons:

  • All the traits of interest on the female selection can be seen or documented, including: growth and development rates; flower characteristics such as size, quantity, smell and color; as well as potential for accumulating THC or CBD, and terpenes. This cannot be said of male plants.
  • Male plants can only express growth and development traits visually. All other bud traits are hidden in their genetic makeup and are not expressed for selection. You can select for pollen sac size and density, but the data so far is inconclusive on how these traits translate to female flower size and density.

You can easily begin by selecting known female strains that have most or all the desired traits that you want expressed in any cross, and by selecting males that are derived from strains having other or stronger vegetative traits that you want incorporated into your new strain.

TIP: Once you’ve selected your P1, or parental lines, you must cross them by gathering mature pollen from the male flower and physically placing it onto the mature female flowers. You can tell when the female flower is ready by observing the stringy, white-yellow stigmas developing from the buds. Many people say these stigmas look like hairs. Tip: Once the stigmas are seen, you can pollinate within a two- or three-week period, so long as pistils are still present and white in color. The males are ready for pollen extraction once you see the oval-shaped anthers starting to split open and release pollen. You can also tell by observing any powdery, yellow pollen accumulating on leaves just under the male flowers.

At this point, make sure you’ve isolated both female and male plants to avoid unwanted cross-pollination and follow these steps:

Step 1. Place a piece of foil or a smooth plastic cup under the pollen sacs while you shake them. You will see the yellow powder (pollen) accumulating. A little bit of pollen goes a long way. TIP: You can break up the total amount of pollen you have collected into packets and freeze them if you intend to use the extra pollen in the future.

Step 2. Isolate the female plant you want to pollinate and either shotgun the entire plant by shaking off your pollen above the plant and letting it float down onto the stigmas, or pollinate specific flowers individually by using either a fine-tipped brush, your finger or a pen cap. Pollinating individual flowers gives the breeder the ability to pollinate the same female plant with pollen from several males at one time. If you take this approach, make sure to label each branch or flower with the specific cross.

In breeding terminology, the female plant typically goes first in the naming convention. For example, “Snake Eyes x Diamond Dust” means Snake Eyes is the female plant receiving the male Diamond Dust pollen.

Step 3. It is imperative that your pollinated female plant is isolated from all other plants while seeds are developing, unless all the female plants are receiving the same male pollen.

Step 4. Provide mother plants with a good source of nutrients, including more nitrogen than what’s included in most bloom nutrient formulas. It may be helpful to switch to a vegetative nutrient schedule to ensure seeds receive what they need during the seed-formation process. Seeds should start forming a few weeks after pollination, and will be busting out of their heavy calyxes several weeks after that. If you need to keep the seeds, save them in a cool, dark place—like a refrigerator.

You have now made your first successful cross! The seeds derived from this cross are called F1. If you continue to cross F1s with each other, the resulting generation is called the F2.

Now you can germinate your F1 seeds and see how they grow. Do they grow fast or slow? How do the buds develop? How long is the flowering stage? What is the smell like? How about the taste, or the potency?

TIP: It may be helpful to keep clones of your plants in case one happens to be a real winner. That way you can use it as part of your breeding program indefinitely.

At this point, it is important to stress record-keeping. TIP: To breed successfully, you must keep great records. Write down which plants were bred together and how their offspring performed. This lets you keep track of traits that show up in the parents and offspring. It will also help you create new strains because you’ll be able to know what traits to expect when breeding certain plants.
