Sinsemilla cannabis seeds

Sinsemilla

Cannabis flowers that were not pollinated during cultivation and do not contain seeds. May also refer to the cultivation technique to create seedless cannabis. The term sinsemilla originates from the combination of two Spanish words: “sin” (without) and “semilla” (seed). Cannabis flowers that mature without pollination have higher levels of essential oils and are notable for being more psychoactive than seeded cannabis. Sinsemilla may also be spelled and pronounced “sensimilla” or “sensimilia,” or abbreviated as “sensi.”

A brief history of sinsemilla cannabis

Before and during the 1970s, cannabis in the United States came in primarily two forms: as hashish and cannabis buds. Dried cannabis flowers imported to the United States from Mexico, Jamaica, Colombia, Panama, and Thailand, among other places, were wild-grown and minimally processed. Primarily known as marijuana by authorities and regulatory bodies, and referred to as grass, pot, and reefer, among many nicknames for the plant by everyone else, this cannabis had copious amounts of seeds. As domestic cannabis production in the United States began to take off in the 1970s, it was discovered that culling male plants before maturation so as to avoid any pollination would result in seedless buds after harvest.

It is not known who first coined the term sinsemilla, but it is theorized that both the cultivation method and the name originated in the southwestern United States. Due to the inherently higher THC content of seedless cannabis than seeded, this product was popularized as a new and potent type of cannabis. The misconception spread that sinsemilla and marijuana were completely different varieties of cannabis, and not the reality that they refer to the same plant simply grown with different cultivation techniques. This dichotomy between the two was used in anti-cannabis propaganda to spread the notion that cannabis was getting stronger, and therefore would allegedly begin to represent an even greater mental health concern to youths, thus needing to be eradicated.

As cannabis consumers realized the advantages that seedless cannabis had to offer (ease of smoking, increased potency, etc.), cultivators increasingly produced more and more sinsemilla. Breeding techniques were developed that allowed growers to grow seedless cannabis for distribution, while selectively pollinating particular branches of the healthiest females) in the crop with pollen from a separate crop of selected male breeding stock. Seeds secured from a few pollinated branches, if carefully germinated to assure a high success rate, can sow a crop for the following year. Advances in greenhouse technology led to the popularization of indoor cannabis cultivation, which further facilitated the production of seedless cannabis, as male and female cannabis plants could be grown adjacently, but in airtight containment to prevent unwanted pollination. The advent of feminized seeds facilitated hobbyist growing by allowing a grower to directly plant a crop of all-female plants sown from purchased, “feminized” seeds, without the need for complex breeding programs.

As seedless cannabis became the norm, the term sinsemilla fell into disuse.

The biology of sinsemilla: why is it more potent?

The development of the sinsemilla growing technique sparked an increase in potency of market cannabis for two reasons. Not only does seedless cannabis contain more THC, but its advent and spread also were the first time selective breeding was used to choose specimens for their increased potency.

The exact biological mechanism describing the increased potency of seedless cannabis from seeded has not been properly studied in a rigorous, scientific manner. However, an understanding of the descriptive botany of cannabis has provided a sound explanation for this phenomenon.

Female cannabis plants begin to flower when the days get shorter 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 to harvest in the fall is commonly referred to as its flowering period. Wild-grown, fertilized cannabis plants produce seeds during this time, and eventually drop them and die as temperatures cool in the fall. However, unfertilized cannabis lives longer and continues to produce flowers for up to a month longer than if it were fertilized. Vegetative growth of the stem and leaves would have ceased at the beginning of the flowering cycle, so all further growth happens in the buds, which become larger and more developed.

In addition to the extra lifetime of unfertilized female cannabis, the extra available metabolic energy that would have otherwise been dedicated to seed production is also thought to be a factor for the increase in potency. Cannabinoids are a component of the sticky oleoresin that forms on the outside of the bracts, the part of the anatomy which holds the seeds. It has been postulated that a lack of hormone-directed metabolism for the production of lipids and proteins in the seed will cause an amplification of the other, existing metabolic pathways: cannabinoid, terpene, and flavonoid biosynthesis.

The increased cannabinoid production in sinsemilla is very clear when looking at available data that tracks cannabis potency from the last 20-30 years. According to an Archival Report from the Society of Biological Psychiatry, the main factor driving the increase in potency of cannabis in the United States is the increase in the proportion of high potency seedless relative to seeded cannabis.

Why sinsemilla?

Edible, nutrient-dense cannabis seeds are sought by small, foraging animals.

In the wild, cannabis has adopted the survival strategy of producing the maximum amount of seeds it can before death in the hopes that enough remain to sow the next generation the following spring. The seeds can make up to 50% of the mass of a dried, seeded cannabis bud, which represents a significant hardship for distribution and consumption of seeded cannabis.

For consumers, seeds are a nuisance that require users to meticulously pick through the buds by hand. Smoked seeds create an unpleasant flavor reminiscent of a coal-fired stove.

Growing Sweet Sinsemilla Bud [The Ultimate Guide]

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 …

Germination

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.
