How To Easily Breed Seeds And Create New Cannabis Strains
Maybe it’s not every growers ambition to start their own seed company – and nobody’s saying you should. Though it can be pretty cool to create your own cannabis strain. Just imagine you’d be the one creating the next Tangerine G13 or Amnesia Haze – or another legendary, award-winning weed variety.
Imagine you’d be the one creating the next Tangerine G13!
Creating own cannabis varieties is pretty easy too and could potentially be a green goldmine. Even if you don’t create the next Super Silver Haze on your first try, it is still worth trying. Cross-breeding your own weed strains is very educative and results in a huge collection of cannabis genetics. Meaning you might hold seeds to strains that are no longer being produced – to cultivate or cross-breed with.
Crossing Weed Strains
There is one thing you definitely need if you’re planning to breed your own weed strains: male cannabis plants. Unless your plan is to make feminized cannabis seeds, which is a different story we’ll dive into another time. To recognize and distinct male from female (and hermaphrodite) weed plants, have a look here.
Because although you can grow male cannabis plants in the same room as female cannabis plants. It’s important to separate the males before their flowers open, releasing their pollen into the room, to avoid uncontrolled fertilization.
Rest assured, there is no need for a separate grow room for the male plants to develop from there. As a flowering male can be held under a simple lightbulb or simply in the windowsill. Furthermore, you can even cut off a few branches and put them in a vase to collect the pollen a week later. Regular Cannabis seeds create male and/or female plants.
Selecting Parents For Your Strain
The trick to select the perfect male weed plant is to have good and above all trained senses. Because it’s up to you to see which male has the best growth and the most attractive (or present) aroma.
Hollow stems on male cannabis plants may indicate high THC-production in its offspring
Obviously, only select male cannabis plants with a nice structure and a healthy root system. If possible, cut off a few branches in search of hollow stems. As a hollow stem in weed plants is often an indicator for high THC-production in the plants.
Male plants that are quick to flower are often dominant in passing on their genes – so it’s best to leave those be. Late-bloomers however, carry recessive genes.
Crossing your female plant with late-blooming males will therefore retain the desired characteristics from your fem – instead of your cross turning into a copy of your male parent. If you’re serious about selecting the right male, make sure you have a separate room for them. As there you can leave them to flower longer, to discover more about their grow characteristics.
How To Collect Cannabis Pollen
Now you’ve selected the right male, it’s time to collect its pollen. A pretty easy job considering the plant is eager to release its pollen to fertilize female plants. Simply shake a branch with open male flowers above a sheet of (black) paper or a plastic container. And the pollen will fall down from the flower onto the desired surface.
Make sure there are no vents on and windows are closed though. As the male cannabis pollen is designed to travel with wind – and in this case we’re trying to contain it to not fertilize the wrong (or too many) female plants. Also avoid working with your female plants right after this job, as pollen easily sticks to your clothing and hair.
Fertilizing Female Weed Plants
Selecting the ideal female cannabis plant is easier than selecting males. As you can truly judge the fruits before you put in the labor. To guarantee a stable plant, try growing her out of seeds and cultivate it from clone too. Thereafter, you can choose the characteristics you like to see in your own creation(s). Be sure to take aroma, structure, flowering time, esthetics, taste and effect into account – as those are the most important elements to look for in a good cannabis plant. Logically, only select the best of the best females to create your own weed seeds with.

Pollinating your female cannabis plants is as easy as collecting male pollen. Preferably wait until the plant(s) you want to fertilize are three to five weeks into their flowering period. Then take the selected female out of the grow room, again, to avoid uncontrolled pollination of the rest of the plants. Label one or more branches to fertilize, to know which plant was crossed with which and when. And use a clean (paint) brush to apply the pollen on one or more branches for seed production – leaving the rest of the flowers to produce seedless weed: sinsemilla.
Deactivating Cannabis Pollen
About three hours after fertilization, it is time to deactivate the leftover pollen on the plant. You can do that by simply spraying your plant with water. Be sure to change your clothes and have a shower after this, before you place the fertilized female back in the room.
After fertilization, you can let your cannabis plants fulfill their flowering period until they are ready to harvest. The seeds are fully grown after two to six weeks, but can stay in the bud and hung to dry after harvest. Your home grown cannabis seeds then require another month before they’re ready to be germinated – preferably with our favorite germination method.
Be sure to keep an eye on them once they start flowering, as you’ve now produced ‘regular cannabis seeds’. This means your plants can turn both male or female when they enter the flowering stage. Providing you with what you need to further stabilize your creation into the perfect weed strain.

The use of high-quality seeds is one of the key requirements for growing healthy cannabis plants. It is true that the final yield depends on numerous factors including adequate watering, availability of nutrients, and good light quality. However, it all starts with superior genetics. In order to ensure that you receive the exact genetics you are looking for, it is important for you to source high-quality cannabis seeds. This will not only provide you the cannabinoid and terpene profiles you desire but will also help get rid of dud seeds.
According to information from i49 , an authentic cannabis seed bank, there are several factors to be examined and evaluated while purchasing seeds. There are certain signs that clearly indicate whether the seed is worth all the effort and hard work or not. Mentioned below are some of these factors.
Feel and Appearance : One of the easiest ways to evaluate the traits and quality of cannabis seed is to get accustomed to their appearance. In general, the outer shells of genetically superior and healthier seeds tend to have darker shades. One of the most obvious signs of some good seeds is grey and black shades with the occasional display of a tiger stripe. The appearance of healthy seeds will also resemble a wax coating on the shell surface, particularly when exposed to bright light.
In addition to a darker shade, better-quality seeds are quite firm and do not bend or break when squeezed between the thumb and index finger. On the other hand, old or poor quality seeds crack and crumble easily under pressure. Please remember that these seeds are nothing but pods of plant genetics. Over a period of time, they get aged and are no longer fit for use. Therefore, do not waste your time on seeds that are past their prime.
You should also avoid using seeds that are immature and young because they are unlikely to germinate. Even if they do, it will take much longer. These seeds can be identified by their green and white appearance.
Avoid Seeds from a Bag : You may consider yourself lucky to find some seeds in your cannabis bag. However, these seeds are not good for a number of reasons. Firstly, this is an indication that the grower has messed up and allowed an invading male to pollinate the female plants. Once pollinated, the female plants shift their focus entirely towards producing seeds and stop producing THC-containing resin. Moreover, the seeds also add to the bag’s overall weight. This certainly means less weed for your money.
Germinate the Seed : One of the best ways to evaluate the genetic potential of cannabis seeds is to simply put them in the soil. You will see the result within a very short time. This option is ideally suited for home growers with adequate time and space to spare. However, this may not be a suitable alternative for commercial growers.
Proper Sourcing : Without any doubt, the most trustworthy source to find great seeds is a reputable seed bank . These organizations have excellent breeding skills and are known to deliver exactly what they advertise to their customers. Many of these seed banks have an excellent reputation in the market.
Float Test : If you are not satisfied after analyzing the appearance and toughness of the seeds and still have doubts about seed quality, carry out the float test. Fill up a glass jar or drinking glass with water and place the seeds on the surface. Seeds that remain floating on the water surface are likely to be of poor quality. On the other hand, healthier seeds will sink to the bottom.
Be patient while conducting the float test because the result may not be seen immediately. Some high-quality seeds need time to absorb enough water and sink to the bottom of the container. Therefore, before confirming the results, you must wait for 1-2 hours.
