Autoflowering strains are those types of Cannabis plants that will automatically flower at a particular age. There are numerous benefits for you when growing autoflowering strains, such as the fact that you can produce many crops a year. In many ways, these plants are easier to grow inside because they are smaller and the reproductive and growing stages of the plant do not need to be separated.

You will find that such plants also mature faster than the usual type of Cannabis. The advantage of these automatic flowering varieties is also that you can grow them in countries where the growing season is shorter, and even if grown indoors, this is an advantage since you can begin harvesting sooner.

Experimenting with genetics has led to the development of different strains including several autoflowering strains of Cannabis. In this article we discuss the five strains that are rated as the strongest strains of 2019.

How strong a particular strain is depends not only on the THC content but also the other chemicals that interact synergistically with the THC to enhance the effects that one gets from the plant. Some of the strains have more of the indica genetics while others are more sativa-like in their features.

These autoflowering plants that you can choose from have been created through genetically crossing different strains of Cannabis to create plants which have the best combination of traits and best possible production value.

The top 5 strains

1. Zkittlez Auto

This strain of Cannabis is known to be fast-growing, with growth taking just over two months. You can’t go wrong with this plant, and if you have never tried this strain you are in for a real treat.
