Everything You Need To Know About Different Types Of Cannabis Seeds
Cannabis cultivation can be complicated, especially if you don’t already have commercial growing experience. There are light cycles, humidity, watering schedules, pesticides, and harvest dates all to consider. However, the arguably most important decision takes place before ever planting.
Growing marijuana plants starts with selecting the right seeds for your operation. Choosing the wrong seeds could have disastrous results depending on a cultivator’s overall goals. Here’s a brief overview of the common types of marijuana seeds and how to use them.
How Cannabis Reproduces
First, it’s essential to understand how cannabis reproduction takes place. Cannabis is a dioecious plant, which means both male and female versions of the plant exist. When growing male and female weed plants together, male cannabis plants pollinate females, causing them to produce seeds.
In the wild, this ensures the plant propagates. However, cultivators attempting to grow potent marijuana will want to avoid pollination. The high-quality buds available in modern dispensaries are known as sensimilla, which means without seeds. These are female plants that haven’t been pollinated. By avoiding the fertilization process, sensimilla plants grow to produce more resin and, therefore, more overall cannabinoids and terpenes. If you’re growing dispensary-grade marijuana, it’s essential to remove any male plants from your crop before they have an opportunity to pollinate. One way to avoid male plants is to use feminized seeds.
What Are Feminized Cannabis Seeds?
Female plants will attempt to pollinate themselves by growing characteristically male pollen sacs if left in a flowering state for too long. Using the pollen from these hermaphroditic plants to flower other female plants is known as rodelization, and it can help eliminate the potential for male plants. A female plant pollinated from a hermaphroditic female will produce feminized seeds—seeds extremely unlikely to carry male genetics.
Another way cultivators create feminized seeds is by spraying their female plants with a chemical called colloidal silver or silver thiosulfate, which encourages the plant to develop pollen sacs.
Whether you create your own feminized seeds or purchase them from wherever you buy cannabis seeds, remember that feminization is not fool-proof. Feminized seeds may still occasionally produce male plants, so be on the lookout to ensure an overlooked male plant doesn’t pollinate your entire crop.
What Are Autoflowering Cannabis Seeds?
Most cannabis plants are photoperiod, meaning that they require specific light cycles to transition from their vegetative stage to their flowering stage. This is done either by seasonal outdoor planting (typically starting around April) or through artificial light manipulation indoors.
However, autoflowering seeds will move to their flowering stage upon maturity, regardless of the light cycle. Autoflowering seeds come from a rare strain of cannabis called cannabis ruderalis, which evolved in northern climates with long summer days. Ruderalis plants typically have lower cannabinoid percentages, so most autoflowering seeds are crossed with a conventional sativa or indica strain.
Autoflowering seeds generally produce smaller plants that have lower total yields, but for some cultivators, this is outweighed by the benefit of reliable harvest times and the ability to grow outdoors year-round.
How To Germinate Seeds
Regardless of whether a cultivator uses regular, feminized, or autoflowering seeds, cannabis seeds need to be germinated before planting.
Seed germination refers to the process by which a seed sprouts. For many plants, seeds will germinate after being planted. However, germinating cannabis seeds requires a special approach since the seeds are so fragile.
There are several ways to germinate weed seeds. The cheapest and easiest way to do this is by placing your seeds between two moist paper towels and letting them sit in a warm location for a few days. You’ll know the seed is ready once it sprouts a white tail.
What Are Cannabis Clones
Not all commercial cannabis plants come from seeds. Sometimes, cultivators can create a clone.
It starts by taking a clipping from an existing cannabis plant. Then, that plant is transplanted into new soil, where it can take root and create an entirely new plant. Plants that are grown in this method will be genetically identical to the original plant that it was clipped from. Not only does cloning plants help save money on seeds, but it also allows cultivators to replicate desirable genetic profiles more consistently.

Once you’ve selected the seeds that will best fit your operation, following these four tips can help maximize yields and better your chances for a successful harvest.
Different Types of Cannabis Seeds
The different types of cannabis seeds available in the market have drastically changed since the 90’s. Before, growers could only choose between indicas, sativas or hybrids in their regular version. Seed banks and breeders have done an amazing job investigating and creating new seeds. Nowadays, there is an unbelievable offer that adapts to anyone interested in cannabis.
Types of cannabis seeds
Indica strains stand out for their optimum yield/ life cycle ratio. They are, in general, more productive than sativas and need less time to complete their development, which is also shorter. Their main advantage is that these types of cannabis seeds grow very dense buds, but that also makes them more prone to mold, specially in humid and hot areas.
Cannabis species differentiate from each other in the characteristics they display during the different growth phases. Indica seeds grow into a spruce shape that reminds us of a Christmas tree. A good way to increase the yield is to use LST techniques or perform apical prunes to make sure light reaches all the parts of the plants equally. Dark green tones and wide leaves give indicas away.
Their short height makes these types of seeds perfect for indoor cultivation or small spaces. Although, their short flowering cycle also makes them ideal for outdoors, as they’ll be ready before first frosts.
Sativa cannabis is less productive than indica plants, which will require growing more plants in order to get the same amount. However, the buds are more spongy anr airy, which grants them greater resistance against humidity and mold. THC levels are higher in sativa seeds and effects are more mental and energetic. This quality plus their exotic and tropical flavors, make sativas very popular among growers.
Just like the buds, the entire plant is stretchy and airy. The light green leaflets are quite apart from one another. Due to their height and the amount of space they need, growing sativas indoors or in balconies is always challenging, as they require pruning techniques to modify vertical growth to horizontal.
Hybrid seeds are a combination of two different genetics, usually sativas and indicas, in order to improve strains’ characteristics. Hybridization’s goal is usually to shorten sativas’ flowering period and promote larger yields with dense and harder buds or grant indicas with exotic flavors and aromas.
Seed banks are constantly hybridizing strains to get new varieties and offer the best possible choices to their clients. When crossing two strains, you get different phenotypes, which essentially are plants with different characteristics but the same genes. Banks then choose the ones that meet the traits they are trying to stabilize and offer the best version.
Ruderalis seeds are less known because seed banks don’t usually sell them.They only use them as part of hybridization processes. A Ruderalis crossed with another type transforms the resulting seed into autoflowering once it is fully stabilized.
Ruderalis cannabis is a wild plant that originated in the coldest areas of north Europe, Central Russia and Siberia. The short hours of sunlight and constant frosts forced these types of plants to adapt to the environment and flower despite lack of light and harsh weather.
These types of seeds have THC levels lower than 3% and grow very little in comparison to other strains. They are compact, hefty and resistant and have a mere weed appearance. Buds are small and fat but their poor THC and CBD levels doesn’t pose any commercial interest apart from hybridizing it to obtain autoflowering plants.
Other types of marijuana seeds
Apart from all the cannabis species that exist according to the type of marijuana seed they come from; cannabis can also be classified in other ways according to their photoperiod dependence, gender or THC and CBD levels.
Regular seeds were the first ones used for cannabis cultivation. Their main characteristic is that they can germinate into male and female plants. This used to be a problem for people that wanted to get large yields out of their crops because these types of seeds used to turn male 90% of the time.
Males produce the necessary pollen for females to create seeds, which can then turn into new plants, but they also produce flowers. A pollinated female will yield poor quality buds full of seeds. A way to prevent this was to get rid of the male plants once they were identified. Currently, these types of seeds are limited to growers or seed banks that create their own hybrids.
Feminized seeds have been modified so that they are incapable of creating male chromosomes, growing only the female plants that produce flowers. Feminizing any type of marijuana seed is a difficult task that requires a lot of time and try-outs to ensure consistency and stability and be able to sell them as feminized varieties.
This process is nowadays 99.9% guaranteed, therefore, there is always a small possibility to germinate a male plant. However, any type of feminized seed is always a better option than a regular one for rookie growers. This way, growers avoid learning to differentiate male from female plants and be on the alert to remove the male plants on time. They also assure obtaining buds at the end of the cultivation process with just basic care.
Autoflowering seeds change phases regardless of their surrounding characteristics. They are auto programmed to enter the flowering period after a certain amount of growth weeks. They are very easy to grow because they can develop even with just a few hours of daily sunlight. As a matter of fact, they are very resistant to light pollution, which means interrupting their hours of darkness won’t affect them.
These seeds are perfect to start gaining growing experience or for people that don’t have enough time to dedicate to their plants. Of course, proper care will increase the final yield.
Autoflowering seeds are created by crossing a regular or feminized seed with a Ruderalis. This way, the new seeds will have a shorter life cycle, the plants will be smaller, more resistant and capable to flower under nearly any circumstance. These plants are ready for harvest 10-12 weeks after their germination. Although they are less productive than feminized, it compensates with the amount of autoflowering crops that can be carried out throughout the year.
All the different types of cannabis seeds of CBD have the same characteristics as feminized, regular or autoflowering seeds but with CBD levels higher than usual. On plenty of occasions THC levels are lowered to the maximum in order for the strains to be used for medical purposes.
However, these seeds aren’t suitable to make CBD based products because their THC levels are never as low as required by current regulations; which is at this moment 0.2%. Hemp seeds are more suitable for that purpose. Either way, CBD-rich marijuana seeds produce more relaxing and de-stressing effects than other seeds.
Contrary to CBD seeds, these types of cannabis seeds do have THC levels lower than 0.2%; therefore, CBD content is predominant. Also called industrial hemp, these seeds are ideal to extract CBD and create products for therapeutic uses. However, CBD levels provided by hemp seeds will never be as high as the one provided by CBD seeds.
Industrial hemp seeds aren’t suitable only to extract cannabidiol. Hemp plants are perfect to make resistant fibers for the textile industry, paper, insulating elements, ropes, motor fuels, paint, cosmetics, etc. Hemp seeds can be ingested in oil form, full, raw, toasted or in flour.
Fast version seeds
Just like CBD seeds, these types of cannabis seeds have the same characteristics as other marijuana seeds but their growth cycle is shorter than usual and they are intended to be harvested before October frosts.
Plenty of these seeds complement each other. Sativas, indicas, hybrids or Ruderalis can also be feminized, regular, autoflowering or fast version. Hemp seeds are only sativas.
Types of cannabis seeds
We would like to explain the difference between the different type of cannabis or marijuana seeds.
What do you have to pay attention to when buying cannabis seeds?
If you want to grow cannabis or weed seeds it’s very important that you cultivate female plants. The male plant only produces pollen and when pollinizes other plants they produce ultimately seed, so these aren’t any good. A female plant produces the flower, your buds. So if you want to grow for personal use, you only need to grow female cannabis plants.
There are numerous cannabis or marijuana seeds on the market. Briefly summarised you can divide these into three groups:
1) Regular cannabis seeds
The regular cannabis seeds are totally natural marijuana seeds that have not been chemically altered. The plants from regular cannabis seeds can both be male and female. If you have ordered 10 regular cannabis seeds for instance, you can’t know if the plants will become male or female, most probably male/famale would be 5/5. When they are cultivated in good circumstances, you are more likely to grow female plants.
2) Feminized cannabis seeds
Feminized cannabis seeds are genetically altered so that they produce female plants in at least 97% of the cases. This forms a great advantage as only female cannabis plants produce flowers. The male cannabis plants don’t produce flowers, contain little THC and can even influence the production of THC of female plants. The female cannabis plant produces considerably more working substances or cannabinoids such as THC, CBD, CBG and CBN than a male cannabis plant. Before bringing the seeds on the market, they are first thoroughly tested and further cultivated so that we are sure that our plants are genetically stable and consistent.
