Last Updated February 22nd, 2023: Are you a cannabis connoisseur looking to expand your horizons into quickly growing your own plants? 

When growing any plant, patience is something you may need to practice having. But, let’s be honest with cannabis- that’s a lot easier said than done. In this article, we will compare 13 incredible early-finishing outdoor strains to see which might be best for you to grow yourself! 

Our Choices For Early Finishing Outdoor Strains

What Makes A Strain Finish Earlier?:

So let’s focus on the cannabis strains that flower as quickly as a month and a half! Generally, Indica strains are faster finishers than Sativas. Indicas have evolved in areas where it’s colder, and the plants need to finish faster as opposed to where the growing seasons are longer and warmer where sativas evolved. Hybrids will have different flower times varying between their parents’ traits. As you may know, a huge concern when it comes to growing is the natural climate changes.

A plant in optimal conditions will finish faster than a plant in lackluster conditions. For example, outdoors, if you had a plant somewhere where a few hours of sun is blocked by a house or a tree, that plant would finish more slowly than if it were placed in full sun without any shade during the day. Early-finishing strains provide the option to avoid the wetter seasons entirely. Helping promote healthy crops that keep growing back. In this article, we will compare 13 incredible early-finishing outdoor strains to see which might be best for you to grow yourself! 

1. Amnesia FAST

Amnesia FAST is the mixture of Soma’s Amnesia and a top-secret hybrid strain. This high THC strain is 70% Sativa and 30% Indica. This specific strain can be cultivated both indoors and outdoors and can grow up to 150 centimeters tall.

However, if planted outdoors, this plant is more likely to reach its true growth potential. Though this strain has a lot of similarities to the original Amnesia strain, this particular seed develops more fruity and floral notes and pack a THC punch of around 20-25%. Along with this, it’s one of the highest yielding indoor strains as well.
