Growing Sweet Sinsemilla Bud [The Ultimate Guide]

Editorial Team

At WayofLeaf, we understand that cannabis cultivation can seem incredibly daunting from a novice grower’s perspective. That’s why we have come up with this complete guide for growing sweet sinsemilla buds.

Sinsemilla is the term for a highly potent form of marijuana that does not contain seeds. It comes from two Spanish words, i.e., ‘sin’ (without) and ‘semilla’ (seed).

When growing sweet sinsemilla buds, the goal is to prevent female plants from being pollinated by male cannabis plants. The reason for this is that unpollinated female cannabis plants produce more resin, and therefore more potent buds.

Under normal growing conditions, the pollen from male plants fertilizes the female plants, which then produce seeds. By deliberately removing the male plants from the grow site, you are preventing fertilization from occurring.

In simple terms, the energy that would have been required by the female plant to produce seeds can be used to create more potent, THC-filled resin glands instead.

Setup – What You Need

Firstly, you need to find out if it is legal or not for you to grow marijuana in your state. In the United States, cannabis cultivation is subject to stringent state laws. Therefore, you will need to familiarize yourself with your own states’ laws around marijuana growing before proceeding.

If it is legal to grow marijuana in your state, then you will need some basic supplies and tools. For the purposes of this article, we will keep it simple and assume that you are a novice grower. Therefore, you will likely use soil as your grow medium (if you are an experienced grower it’s possible to grow sweet sinsemilla bud using a hydroponic setup).

Naturally, you will need marijuana seeds, which you can purchase from your local dispensary or online.

You can guarantee female plants by purchasing feminized seeds. If you use regular seeds, then you will need to remove the male plants from your grow site. We will discuss this later. You can also grow sweet sinsemilla bud by using a clone, i.e., a cutting from a mature female plant.

You’re also going to need the general supplies just as you would if you were growing any other plants. For example, some gardening tools, e.g., pruning shears, as well as high-quality soil, fertilizer, and pots.

You might be wondering whether you should grow your sweet sinsemilla buds indoors or outdoors. Well, experienced cultivators recommended growing your sweet sinsemilla plants indoors. If you grow your plants outdoors, then you run the risk of them being inadvertently fertilized by pollen in the air.

Weighing up the pros and cons …


Before planting your marijuana seeds, you will first need to germinate them. Germination is the process whereby a seed develops into a plant. The process begins when the seed absorbs water. This is known as imbibition. The water then activates proteins and enzymes contained within the seed, and it produces a root.

To begin the germination process, place the seeds in a glass of tap water for about fifteen to eighteen hours. Wait for all of the seeds to sink to the bottom of the glass. Then pour the glass of water containing the seeds onto a paper towel. Place the paper towel onto a heat mat with a bowl over the top to keep the moisture in. Be careful not to let the paper towel dry out as this could kill the seeds.

Check on the seeds every five hours for up to 24 hours to see if the seeds have produced tap roots. The taproots will be thin and white in appearance and be at least half an inch in length. After that comes the transplanting.

The Vegetative Stage

Transfer your germinated seeds into a small soil pot, being careful not to overcrowd them. Enrich the soil with a high nitrogen and potassium fertilizer blend for healthier plants and faster growth. Experienced growers recommend using liquid fertilizers for a more straightforward application and higher nutrient availability.

The plants will grow significantly as they progress during the vegetative stage. You will need to transfer them to a larger container to prevent them from becoming overcrowded.

It is essential to carefully prune and top the plants during the vegetative stage to keep their height and shape under control. Remove any large fan leaves from the lower canopy to improve air circulation and light distribution to the lower nodes. Continue to water the plants as needed, and boost their growth by fertilizing the soil with nitrogen.

Identifying and Removing All of the Male Plants

Next comes the most crucial stage of growing sweet sinsemilla buds. Removing the male plants from the grow site. The male plants are easily identifiable by a couple of different physical characteristics. Male plants have much thicker, sturdier stalks, and tend to have fewer leaves than their female counterparts.

You can also identify a cannabis plant’s gender by examining what is growing between its nodes. The nodes are where the leaves and branches extend outwards from the stalk. Male plants have pollen sacs that are designed to spread pollen for fertilization purposes. Female plants have a stigma, which catches pollen from the air.

These physical characteristics are recognizable even before they have become functional. This gives you a bit of time to act before it becomes too late to prevent fertilization.

At this stage, these parts of the plants are known as “pre-flowers.” They begin to develop approximately four weeks into the vegetative stage. They are tiny and difficult to identify using the naked eye. Therefore, you will need to use a magnifying glass. The males will have small pollen sacs, whereas the females will have two bracts, and will ultimately produce a hair-like stigma.

Now that you have identified the males, it is time to remove them from the grow site. Using pruning shears, remove the male plants by cutting the stalks about six inches from the ground. Why don’t you just pull the male plants out of the soil? Well, by cutting the stalks, you prevent damaging or unsettling the roots of the adjacent female plants. Damaging the roots could potentially hinder the growth and development of the remaining female plants.

As already mentioned, the reason you need to remove the male plants is to ensure they don’t pollinate the females. Come harvest time; you should be left with excellent, high quality, and high-THC sweet sinsemilla buds with no seeds.

Sweet Sinsemilla – The Flowering Stage

When the sinsemilla plants enter the flowering stage, it is essential to stop pruning. For best results, feed the plants Liquinox Bloom plant food, which contains a high amount of phosphorus and potash. This should help the plants to develop healthier and larger flowers.

Experienced sweet sinsemilla growers recommend not watering the plants late in the flowering stage. While this will cause the plants to dry out, it theoretically causes them to produce more resin.

Harvesting Your Sweet Sinsemilla Bud

Many sinsemilla growers recommend harvesting the plants by cutting the stalks six inches above the ground. The next step is to dry and cure the sweet sinsemilla buds. Large scale outdoor growers advise hanging the whole plants upside down and only exposing them to reflected, not direct light. Small-scale indoor growers can use drying racks. Bear in mind; a slow drying process is best.

Once the plants are completely dry, next remove all the leaves and stems, leaving only the sweet sinsemilla bud. Remove the buds and place them in sealed, airtight containers, such as a wide-mouthed mason jar. It is essential to store these containers in a cool, dry place.

You will need to open the jars a few times a day for the first couple of weeks. This is to allow the buds to breathe and let any moisture that has built up inside to escape. It will take approximately four to six weeks for the buds to cure fully.

What Does Sinsemilla Mean, And Why Is It Important?

If you love cannabis, you’ve probably come across the word sinsemilla. Is sinsemilla some special kind of cannabis? Where does it come from? Read on to find out!

If you’re interested in cannabis and cannabis culture (and we have an inkling you may well be…), chances are you’ve come across the word “sinsemilla”. Interestingly enough, there is some confusion among people as to what sinsemilla really means.

In the same way that some weed lovers in the UK freely use the word “Skunk” to describe top-notch bud, so too do some folks use “sinsemilla” to describe special varieties of super-potent weed that come from places like Amsterdam. Here’s what sinsemilla really means.


The word sinsemilla comes from the Spanish words “sin” (“without”) and “semilla” (“seed”), so it literally translates to “without seeds”. Contrary to what some may think, sinsemilla cannabis does not refer to a specific strain, subtype, or geographic location. The word is simply used to describe seedless cannabis flowers that come from unfertilised female plants.

That said, the first interpretation that sinsemilla stands for darn good and very potent weed isn’t so wrong. Indeed, seedless cannabis is more potent, tastes better, and is simply of overall higher quality than weed full of seeds.


Pollinated female cannabis plants spend a lot of their energy on producing seeds. But unless you are a breeder and require the seeds, this is not what you want. Unfertilised females don’t produce seeds, but instead spend energy on producing resin. As such, seedless buds have higher levels of cannabinoids and aromatic substances—they are more potent and will taste better.


In the past, long before cannabis cultivation in the West was established, cannabis and hash were almost exclusively imported. Dried flowers usually came from Mexico, where cannabis was grown in the wild without the care and tech of today’s grow operations. A lot of the imported “grass” had plenty of seeds in it, so it wasn’t really what one would consider quality bud.

Once breeders found out that separating male plants from the females resulted in seedless buds of much better quality, we never looked back.

It is thought that the word sinsemilla was coined in the 1970s, around the time when cultivation started ramping up in the US and Europe. Here it was used to differentiate seedless weed from the poorer stock. As the “new” weed was indeed better and more potent, this gave rise to the misconception of sinsemilla being a different, very strong variety of cannabis.

Truth was, of course, that it was still the same weed from the same strains. The only difference was in how it was cultivated. What’s more, this alleged new kind of powerful cannabis fuelled anti-cannabis propaganda, as weed suddenly became more “dangerous” in the eyes of the establishment.



As knowledge spread that seedless cannabis flowers made for a far better product, growers started focusing on producing sinsemilla exclusively, culling male plants as soon as they could. If they required seeds for breeding, they kept the sexes strictly separated and only allowed pollination of select female plants in dedicated areas.

A little later, when indoor cultivation became popular, the separation of male and female cannabis plants became even easier and more commonplace. Growers could simply keep each in a separate grow room or tent to limit the risk of accidental pollination.


But the real breakthrough with growing sinsemilla came with the invention of feminized cannabis seeds in the 1990s. Previously, when growing from regular seeds, growers would need to cull the males as soon as possible. Feminized seeds did away with this concern, allowing growers to cultivate female plants only. The issue of seedy buds soon became a thing of the past. As a result, the term sinsemilla has lost some of its relevance in the modern day.


Sinsemilla, as we explained, just describes bud without seeds. The word can be used for any type of female cannabis plant that wasn’t fertilised, regardless of the strain. As such, sinsemilla can be either indica or sativa.


Of course. Less seeds means more flowers, more resin, more aroma, and more “oomph” when you’re smoking. The purpose of sinsemilla is to give folks the best cannabis experience. So yes, sinsemilla means it’s time to blaze!


Sinsemilla is really just another word for feminized cannabis. In this day and age, where weed is grown in controlled environments, it is easier than ever for growers to ensure their crops are entirely female. You don’t need to worry about accidental pollination spoiling your harvests. What you’re growing today is almost always sinsemilla—great bud, minus the seeds!
