How to choose our marijuana seeds?

To choose between one of the categories of marijuana seeds, the first thing we must know is the difference between them.

Feminized marijuana seeds

Feminized marijuana seeds are those that will give almost 100% female plants, in terms of growing cycle, indoors they will need a growth period of 18 hours of light and 6 hours of darkness and a flowering period of 12 hours of light. and 12 hours of darkness. In outdoor cultivation, the complete cycle usually lasts between 5 or 6 months, starting to cultivate them in March / April and harvesting in September / October. They are usually large plants, and can easily exceed 2 meters. Conclusion, if we are looking for female varieties, of large size, with large harvests and we are not in a hurry, without a doubt we should select this category.

Autoflowering marijuana seeds

Autoflowering marijuana seeds are very fast cannabis strains, they are also feminized, which means that they will give almost 100% female plants. The difference from normal varieties is that autoflowering varieties do not need a time change to start flowering. Indoors they will need 18 to 20 hours of light to produce large crops and are usually ready in 7 to 12 weeks after germination. In outdoor cultivation they will be ready to harvest in a super fast time since the fastest varieties can be ready in 7 weeks from germination. In conclusion, if we are looking for a small and very fast variety, we must choose between the autoflowering marijuana varieties.

Regular marijuana seeds

When planting regular marijuana seeds we will not know the sex of our plants until after a while, once the sex is declared we must select the female plants and eliminate or separate the males, since otherwise the females would pollinate. Once the females have been selected, the cultivation is exactly like that of feminized seeds. The difference is that these varieties are more stable, grow more vigorously and the genetics are purer. If we know how to select the sex of the plants and we look for purer genetics, we can select this category, if this is not the case we recommend the cultivation of feminized marijuana seeds.

CBD marijuana seeds

Within the category of CBD marijuana seeds we will also find feminized marijuana seeds and autoflowering seeds, now we know the difference between them and we can choose the one we want. The difference with the classic varieties is that they do not contain high percentages of THC, some can have percentages as low as 0.2% THC and very high percentages of CBD. These types of plants are the most used by those who want to treat or alleviate some type of pain or disease. But they are also highly valued by those growers who want to smoke marijuana without feeling that psychoactive effect. Conclusion, If we are looking for varieties with little THC and medicinal properties, this is our category.

Fast version marijuana seeds

Fast version seeds are a mix between normal and autoflowering varieties, they behave and are grown like a classic feminized variety, but they are faster. Being able to cut the flowering times in 2 weeks, both indoors and outdoors. As a drawback, they produce a little less than the classic varieties, although the yields are higher than those of the autoflowering ones. Conclusion, if we are looking for a fast feminized variety, but we consider the cars very small and that they produce little, we can try the fast version.

Once the category is selected, we must ask ourselves several questions about the type of variety we are looking for. That is, we will have to ask ourselves the type of effect we are looking for, the flavor and aroma we prefer, if we are looking for varieties that are very strong in THC or what we are interested in is production. If we continue reading we will explain the different types of effects, flavors, aromas and strengths, we will even classify the most productive marijuana varieties of the moment.

Different types of effects of marijuana

In cannabis we can find many different types of effects, how can we choose the desired effect? Well, the truth is quite simple if we know the difference between Indica and Sativa varieties. Next, we will explain a little the differences between Sativas and Indicas.

Sativa marijuana seeds

Sativa marijuana strains are plants with a more stretched structure, they tend to grow a lot in height, but with a thin structure. It produces thin leaves and they are plants that need enough fertilizer to grow without deficiencies. As for the effect, they are varieties with a stimulating, more cerebral effect. We recommend these types of varieties to those looking for a more active effect, more for the day, to work and to increase creativity.

Indica marijuana seeds

Indica marijuana strains have a very robust structure, plants that develop a lot in width, but with a shorter height than sativas. They are easier to grow plants, since they do not need as much fertilizer as sativas. As for effect, they are varieties that have a more corporal effect, the effect is more relaxing. We recommend these varieties more for the night, or for those moments that you are looking for peace and relaxation.

indica vs sativa

Once we know the difference between Indica and Sativas and we are clear about the type of effect we want, we must select the flavor and aroma that we prefer.

Different aromas and flavors in marijuana

Well, with the work that seed banks do in developing different genetics, it can be said that we can find all kinds of flavors in marijuana. For that reason we must be clear about our tastes and choose well. Next, we will see a photo with the different flavors.

Marijuana flavors

We find varieties of marijuana with fruity flavors, marijuana flavored with orange, strawberry, raspberry, mango, pineapple, etc.
Varieties of marijuana with flavors of spices and herbs, such as pepper, cinnamon, mint, ginger, saffron, etc.
Marijuana varieties with more bitter or earthy flavors, such as wood, garlic, coffee, metallic, pistachio, even varieties with fuel flavor.
Varieties with more citrus flavors, such as lemon, grapefruit, lime, orange, mandarin, etc.

In the seed finder we can select the type of variety we want, marking the boxes of what interests us.

Once we have selected the flavor and aroma we want, we will only have to choose between the results of the varieties, among them we can select the most powerful in THC, or the most productive, or those that produce the most resin. It will already depend on the needs of each one.


After many years in the sale of marijuana seeds, many of our customers ask us regularly which is the best marijuana seed, answering with total sincerity, there are no the best marijuana seeds. Well, it's not really that it doesn't exist, it does exist, but it will be the best variety of marijuana in our opinion and it may not fit our needs or tastes. For example, if for us the best cannabis strain is Mimosa from Barney’s Farm, you may not like this strain. You may not like it for many reasons, it is a very powerful variety and maybe it is not what you want, it is an Indica variety and maybe you are looking for a sativa. So we advise that when buying marijuana seeds, you ask yourself what you are looking for or what you like the most. And so try to find your best variety.

Even so, we are going to try to make a selection of our best varieties.


Many times we meet clients who ask for seeds for outdoors, the truth is that almost all varieties of marijuana can be grown outdoors. There are very few varieties that cannot be grown outdoors, the only thing we have to look at is the harvest time, that is, if we are looking at a variety and we realize that the harvest is in mid-November, we do not recommend that variety. Unless you live in an area with good weather for those dates. In Europe that variety would be discarded if we do not have a greenhouse.

We are working to offer you our selection of outdoor varieties.

Outdoor crop


As for the best indoor marijuana seeds, we insist on the same, to know which variety we should grow we will ask ourselves the following questions; Feminized, autoflowering, regular, CBD's or Fast version? Flowering time? Flavor and smell? Indica or Sativa? Once we have answered these questions, we will surely have to find the best variety of marijuana for indoor use.

We are working to make a selection of our best indoor varieties.

Indoor crop


If what we want to know is when to start growing marijuana outdoors, in Europe we should start more or less in March / April, we should control the outside temperature and it should be at least 17ºC. To know the day on which the seeds will germinate, then we will be guided by the lunar calendar.

For indoor cultivation we can germinate our seeds the month we want, since we will adjust the parameters to the needs of the plants. We will only have to be guided by the lunar calendar to know which days it is most advisable to germinate marijuana seeds.

Moon phases



Once the lunar calendar has been consulted, we will know exactly the day that we can germinate the seeds, then we will prepare for it.

Material needed to germinate the seeds:
In order to germinate the seeds we need kitchen paper, 2 plates, seeds, a little water and a place where the temperature is between 21 and 25ºC. If you want to know how to germinate the seeds step by step, we recommend that you read the article "Germinate marijuana seeds"

Marijuana seed germination


Marijuana seeds take approximately 36/48 hours to germinate, some varieties may take a little longer. But if from the fourth day, the seeds have not germinated, I regret to tell you that there is not much chance of it happening ...


There are many factors that can cause marijuana seeds not to germinate, but the most common are excess water, lack of aeration and lack of temperature. You have to be very careful with the parameters, otherwise we could rot the seeds.

Another factor that can make our seeds not germinate is that they are too old. At Calle25 we renew our stock very often so that this does not happen.

If you have very old seeds and / or want to ensure germination, you can use Seedbooster plus.

Conservation of Marijuana Seeds

For a good conservation, the ideal temperature for storing the seeds is between 4 and 7 degrees Celsius, it is normally the temperature that we have in our domestic refrigerators. To avoid unwanted germination they should be kept in dry conditions, we advise not to remove them from their original packaging.
