Whether a veteran or newbie in the cannabis world, you will realize that you are a little hazy to respond if anyone asked you, "What is  sinsemilla?” Well, some people describe it as a prime, seedless cannabis flower that has been grown with the utmost care, while others believe that sinsemilla weed is a pure strain of extremely potent marijuana that is grown in the American Southwest and some parts of Amsterdam.

Please note that there is no sinsemilla strain. 

Sinsemilla: What Does It Mean?

The word sinsemilla was derived from two Spanish words: “sin” which means without and “semilla” which means seed, so it just means "without seed”. Unlike what many people think, sinsemilla weed does not refer to a specific strain.

The word simply describes seedless cannabis flowers that come from unfertilized female plants. Sinsemilla weed tastes better and has a higher quality compared to the weed full of seeds.

Why Sinsemilla?

Did you know that pollinated female cannabis plants spend a lot of their energy on the production of seeds? Now you know. Unless you are a breeder or planning to be one, you do not want to wait that long.

Edible nutrient-dense cannabis seeds are sought by foraging animals. Cannabis has adopted the survival tactics of producing the maximum number of seeds it can before death hoping that enough will remain to show the next generation. The seeds contribute up to 50% of dried cannabis bud, which represents a significant hardship of the consumption and distribution of seeded cannabis.

Seeds are a nuisance that requires users to pick through the buds by hand. Smoked seeds create an unpleasant flavor that is not only unhealthy but smelly. For these reasons, sinsemilla weed has become a preferred option.

We have already seen that unfertilized female plants will not produce seeds, instead, it will produce resin. Seedless buds have higher levels of THC and aromatic substances, which make them more potent, and with a better taste.


How To Grow Sinsemilla Weed

The plants are usually grown indoors, under greenhouse conditions using hydroponic techniques. This is to avoid the fertilization of the female cannabis plant. We all know that after fertilization seeds are formed. This should not happen if you intend to nature a sinsemilla weed plant.

The plant contains a very high percentage of THC, usually around 10% or more. This figure increases if the plant is grown using hydroponic techniques.

 Set Up – What Do You Need?

The primary step is in ascertaining if it’s legal or not to grow weed in your country. It’s obvious you will need sinsemilla seeds which you can purchase from a local dispensary or online.

You will also need supplies just as you would if you were growing any other plant.


This is a process whereby a seed develops into a plant. Always germinate your sinsemilla seeds before planting. The germination process begins when the seeds start to take in water. Water, therefore, activates proteins and enzymes contained within the seed and to produce a root.

The vegetative stage

Transfer your germinated seeds into a small pot and then add high nitrogen and potassium fertilizer blend to the soil for faster growth. Experts recommend liquid fertilizers for a straightforward application.

The plants grow significantly while progressing during the vegetative stage. Do not forget to transfer the plants to a bigger container to avoid overcrowding.

The flowering stage

Feed the plants with Liquinox bloom plant food. The food has a high amount of potash and phosphorus. This should help the plants develop healthier and larger flowers.

Remember it’s not advisable to water the plants in the late flowering stage.


  • Cut the stalk six inches above the ground
  • Dry and cure the buds- a slow drying process is the best
  • Remove the leaves and stems leaving only the wanted sinsemilla bud.
  • Remove those buds and stockpile them in sealed containers

You need to open the jars a few times a day. This is to allow the buds to breathe and let the moisture escape. In four to six weeks the buds will have been cured fully.

The Biology Behind Sinsemilla

A female plant will begin to flower in the late summer. The amount of time it takes from the first sign of showing flowers to when they are fully ripe and ready for harvest is referred to as the flowering period. During this period, fertilized cannabis plants produce seeds and eventually drop them and die as the temperature cools.

However, unfertilized cannabis plants live longer and continue to produce flowers for up to a month or longer. Vegetative growth of the stem and leaves would have ceased at the beginning of the flowering cycle, so all full growth happens in the buds which become larger and more developed.

The extra metabolic energy that would have been dedicated to seed production is considered as a factor contributing to the increased potency. Cannabinoids are a component of the stick resin that forms on the outside of the bracts, the part which holds the seeds.

It has been found that a lack of hormone-directed metabolism for the production of lipids and proteins in the seed will cause an application of other existing metabolic pathways which are terpene, biosynthesis, and cannabinoid.

The increased cannabinoid production in a sinsemilla weed plant is clear when looking at available data that track cannabis potency from the last 20 years. The critical factor that necessitated the increase of potency of cannabis is the increase in the proportion of high potency seedless cannabis.

Using Sinsemilla

You can add Sinsemilla to tobacco and smoke it as a “spliff” or on its own. Of course, your manner of smoking will depend on your preference. You can also smoke it using a bong, which is one of the major ways users prefer.

Effects Of Sinsemilla

After using sinsemilla, you might find that you experience heightened awareness of color, increased appetite, and elation.

Frequently Asked Questions (FAQs)

Q: Is sinsemilla sativa or indica?

A: As mentioned earlier, we do not have any sinsemilla strain. The term just describes a bud without seeds.  It can be either Indica or Sativa.

Q: Can you smoke sinsemilla?

A: Of course! Fewer seeds favor the production of resin, flowers, and “oomph” when smoking. Who doesn’t want to enjoy this? The purpose is to give you the best cannabis expected.

Bottom line

Sinsemilla is just a synonym for feminized cannabis. Today, weed is grown in controlled environments, making it easier for growers to ensure that their plants are entirely female.
