Seeds THC of feminized cannabis, in our online seeds shop we offer a large selection of cannabis seeds with a high content of THC feminized. The classic photoperiod strains or the new autoflowering strains. We of Grace Genetics we have worked hard to select high quality cannabis seed genetics with deferential genetic heritage. Cannabis Indica, Cannabis Sativa or a Hybrid.

Photoperiod cannabis seeds make their appearance on the market around 2006-2007, thanks to this new production method growers can be at ease in cultivating their plants without the need to then proceed to eliminate the males to avoid to pollinate the flowers and obtain buds full of hemp seeds. This has allowed feminized cannabis seeds to conquer the majority of cannabis growers in a short time, almost 15 years later and it is practically impossible to find any seed bank without feminized seeds.

The active ingredient in marijuana (THC), in these plants, will explode to supernatural levels. Low CBD levels never exceeding 2%, unlike the genetics of CBD Seeds which are rich in cbd and are generally referred to as "Cannabis Sativa".


Planting feminized cannabis seeds is undoubtedly the most common method used by modern growers, and now they cannot afford conventional cannabis seeds which must be covered. Today, in the northernmost region of the earth, people have developed techniques for indoor cultivation, and the effect is very satisfying. Hence, a huge market for feminized and autoflowering cannabis seeds has arisen and grown, which can be sold for harvesting in almost any country in the world. In this category of our seeds shop you can find many feminized cannabis seeds. Choose from us the best indoor or outdoor feminized seeds and you will find the best feminized marijuana seed bank.


In contrast, autoflowering seeds are light-independent cannabis species with a very short life cycle. In recent years, the sale of autoflowering seeds has increased exponentially thanks to their very rapid growth and short stature, which makes autoflowering seeds very easy to blend into the vegetation of the garden or terrace.


Indeed, cannabis plants can be male or female (and sometimes hermaphroditic), which leads to huge differences in yield. Indeed, the male plants can be used to propagate this species through pollination, and their fibers are widely used in the textile market, while the female plants are mainly used to produce inflorescences. Feminized seeds are special marijuana seeds that have a 99,9% chance of producing female cannabis plants.


In nature, cannabis plants are all born under dioecious species, that is, there are some male and female specimens that interbreed to create new specimens. Regular seeds are those that can produce both male and female plants and the grower cannot control their sex. The probability of female plant births is the same probability of male plant births, hence the 50%/50% ratio. For this reason, growers who want to harvest excellent inflorescences will opt for feminized seeds for the certainty of having only female plants in their cultivation. Farmers who choose regular seeds, in general, use them for a large production of cannabis seeds.

Cannabis seeds can be purchased in physical stores or through online seed banks like us at Grace Genetics! As of today, in 2023, cannabis seeds can be bought almost everywhere, thanks to the progress towards legalization in many countries around the world, but particular attention must be paid to which seed bank to choose.

This is a fundamental step for the success of our future cannabis seed cultivation, in fact by buying cannabis seeds in an unreliable seed bank we would certainly be buying poor quality cannabis seeds, this will mean cannabis seeds with a low germination rate (40-50%), so half of our cannabis seeds will definitely not even germinate. In addition to this, poor quality cannabis seeds produce very small final yields.

Precisely for this reason, for the purchase of cannabis seeds, it is necessary to choose a reputed seeds bank with high levels of reviews, like us at Grace Genetics. since 2017 Grace Genetics supplies the largest European growers of cannabis seeds of the highest quality, always fresh and ready-to-sow cannabis seeds with a germination rate of 99,9%!


Germinating cannabis seeds is a highly risky process if done incorrectly, remember first of all that cleanliness and delicacy are required to be able to germinate cannabis seeds. Cannabis seeds are small living beings which, like us humans, must be treated with due care in order to "be born" (germinate).

Second of Grace Genetics, the best and safest method to germinate cannabis seeds is to use a paper towel. You must first place the cannabis seeds in a sheet of paper slightly wet with water (it must not be excessively waterlogged), we also place another sheet of paper on top of the seeds. After 4-5 days the cannabis seeds will have developed a very small white root and that will be the time to plant them in the soil.


After having carried out the actual process of germinating the cannabis seeds, we proceed with the final step: planting a cannabis seed in the ground! First we make small 1-2 cm holes in the soil, place the cannabis seed inside with the white root facing down and water with a little water (without exaggerating with the amount of water).

If we grow indoors, we place a grow lamp lit 15 hours a day at a height of 20-18 cm. If, on the other hand, we grow cannabis seeds outdoors, then mother nature will take care of the entire growth and flowering process of the cannabis plant.

Cannabis seeds are excluded from the notion of narcotic substance as they do not contain any active ingredients, the mere possession of cannabis seeds is not a crime in most countries of the world. Germination, on the other hand, is prohibited, although in some situations it is highly tolerated.  

This is one of the first questions a grower asks himself, the answer to this question is impossible to give. The factors that regulate productivity are many, a feminized variety grown indoors using training techniques will produce even 500 grams per plant, while an autoflowering in an open field will produce up to 40 grams.

Cannabis it needs 2 things as well as a pot with soil, Luce e water. If your window sill is your only option, using a pot of at least 4-5 liters can produce extraordinary results with the microgrowing and training techniques. 

Buying high quality cannabis seeds is the first step that will lead us to the success of our cultivation. We of Grace Genetics thanks to 10 years of experience in cannabis we are able to always guarantee fresh seeds that meet our high quality standards. We cultivate your passion. 

I semi automatic of cannabis flower at a set time regardless of the hours of light, we can maximize by giving it even 20 hours of light during the day. On the other hand, the varieties of feminized cannabis or photoperiod they will remain in perennial vegetative with 18 hours of light to trigger flowering it will be necessary to give them a maximum of 12 hours a day. When instead we encounter a seed of regular cannabis it means that it is not feminized and will develop one or the other sex depending on the case.
