The genetics of the cannabis seeds you plant are responsible for dictating both the speed and quality of the marijuana plant it will grow into. It even plays a role in the potency and flavor profile when the marijuana is being consumed, by affecting the quality and quantity of cannabanoids and terpenes.

Each strain of marijuana is best explored personally, to experience the different taste profiles and effects. However even within the same marijuana strain, there are large amounts of discrepancies with their genetics - and this is where the reputable seed breeding companies come into play: There are countless factors leading to the production of seeds with strong genetics and with the addition of so many new strains it has become more common to find unstable genetics. However, each year the genetics of existing strains continue to grow stronger - with the breeders doubling down and breeding out undesirable traits.

We have collected a list of contenders for the top genetics to be growing during 2020.
You can learn more about each strain by clicking into it, or browsing more information about the breeder including their complete product line.
