Cannabis Seeds How To Choose Them

in this article we are going to see how to choose cannabis seeds, we will start with a bit of general smattering on the natural and non-natural history of seeds.

Cannabis its evolution

cannabis is a plant that reproduces by seed, the male flower takes care of inseminating the female one and from this natural process the seeds are formed.

cannabis is millions of years old, it is a plant that was formed like many other plants and evolved according to the surrounding environment.

Theoretically, during the period of Pangea there was only one variety of the world, which then evolved over the course of time and therefore with the separation of the continents

today we therefore have three original varieties sativa indicates e ruderalis in this article you can read more information.

The history of cannabis seeds

the first cannabis seeds used by growers were indigenous seeds that came from the continents where they evolved.

the autochthonous seed is therefore a natural male and female seed that possesses the characteristics to be able to survive in a given environment.

in autochthonous seeds there are no equal plants, the seed has thousands of genetics that can be selected as desired.

initially therefore the seeds that were used were regular and produced cannabis with seeds, due to pollination.

over time and starting in the early 70s 80s growers have evolved starting to hybridize plants.

hybridization allowed to have feminized seeds and various types of crosses that are sold today by seed banks.

Cannabis seeds and strains

The varieties that have been created over time and are sold therefore are mostly hybrid selections.

selections made by man to research certain characteristics of the plant such as; a taste, a smell or a particular gift of resistance you have parasites.

it is clear that the plants have been selected to seek the maximum THC available, but lately new active ingredients are being sought such as; CBD, CBN or CBG.

in hybrid phenotypes they are divided into these categories

  • Regular
  • Feminized
  • Fast releases
  • Autoflowering

Regular Cannabis Seeds

i regular cannabis seeds they are mostly hybrid seeds that contain males and females within them.

this type of seeds is used only by professional growers for selection of mothers or for crosses.

some old fashioned growers use them because they know the vigor of these seeds is better than feminized ones.

but in any case it will be necessary to eliminate the males if we want to obtain the flower without the seeds.

the Feminized Cannabis Seeds

i feminized cannabis seeds they are seeds that possess only the female gender.

This type of seed can be grown without removing the males and is therefore suitable for flower cultivation.

usually this type of seed does not contain many phenotypes, at most two or three if the seed is correctly stabilized.

in this sense we will have plants with a certain shape, a certain flavor and active principle.

this type of seed follows an 18-hour light cycle indoors for the first two months, then switches to a 12-hour light cycle for another three months.

outdoors it is planted from March to end in September but it also depends on the latitude of your state.

the Cannabis Seeds in Fast Version

this kind of cannabis seeds they are one of the latest found by seed banks.

this type of plant follows the natural cycle of light of the plant, but when it enters flowering because the hours of light are lowered, it takes less time to complete its cycle.

the outdoor cycle of these plants finishes in about 4 and a half months, and provides good plants but will never be as big as the feminized or regular.

they can also be grown indoors with the same method as the feminized ones.

Autoflowering Cannabis Seeds

this kind of cannabis seeds it is named this way because it does not follow the natural light cycle to flower.

this seed has an internal timer which leads this plant to have a complete cycle in about 3 months.

the plant can be grown both indoors and outdoors, the more hours of light it takes and the more abundant the product will be.

clearly it cannot be compared to plants like the ones previously this because its production is very small as its height.

in any case, many growers use it because it takes up little space and goes well with small growboxes.

Sativa Indica or Ruderalis

on the web there are a great variety of seeds, and among the varieties we mentioned earlier we can divide the seeds into two other varieties.

indica cannabis seeds are seeds that originally had more THC and less CBD and indica plants will have a shorter, more tapered shape, which is great for growing indoors.

sativa cannabis seeds, on the other hand, are seeds that originally had more CBD and less THC, this type of plant is longer and tapered and reaches considerable heights.

when choosing the seed pay attention to its percentage, being hybrids they will have a percentage of indica and a percentage of sativa and you will see that you will have the desired plants.

Reports of Active Ingredients

Generally an indica plant should have more THC while a sativa plant should have more CBD.


With hybrids this concept does not apply because the plants with the active ingredients considered useful for the grower have been selected.


for this reason there are three types of commercial seeds.

  • THC seeds
  • CBD seeds
  • Semi ratio 1-1

THC seeds are seeds with a 20 to 1 THC – CBD ratio and usually contain 20% THC and 1% CBD

CBD seeds are seeds with a 20 to 1 CBD to THC ratio and typically contain 10-15% CBD and 0,5% THC

the 1-1 ratio seeds are seeds called curatives that have an equal CBD - THC ratio, this type of seed has remarkable therapeutic properties.

now that you know all about the seeds I think it will be easier for you to choose the most suitable one.
