Here are the top 5 autoflowering strains available, that contain the most THC. Autoflowering plants are a very popular choice among pro growers and breeders. They are also popular among those growing on a small scale for nothing more than personal use, due to several genetic characteristics, that make them popular for doing so.

Autoflowering strains are created by introducing the genetics of a Cannabis ruderalis plants to a grow space occupied by either sativa or indica strains. Cannabis ruderalis adapted to colder northern climate in comparison to its cousins indica and sativa. This meant less sunlight, so it had to make the most out of the little it had in order to photosynthesis and survive. For this reason, when growing an autoflowering strain, the grower does not have to alter the light cycle, like they would have to do if the strains they are growing did not have the autoflowering trait. Autoflowering plants usually flower within a small timeframe. Plus, Cannabis ruderalis is quite small and compact, which it contributes via its genetic makeup.

Thinking about growing a strain super high in THC? Why not try one of these hard-hitting autoflowering plants for an easier growing experience? Here are the top 5 cannabis strains, that share both of these properties.
