Easy and fast growing feminised cannabis strains

Want to try growing lots of different strains but only have one tent? Looking to maximize your grow capacity? One of the options is to grow more often!

Planting only the fastest growing strains can enable you to have a fast turnover in your tent. Strains with a short flowering time are often autoflowering seeds so we decided to select mainly feminised strains. Below you’ll find some of the best short flowering – fast growing strains we could find. 

Before we start it’s important to point out that some strains have greatly evolved over the years and despite having the same name, depending on which vendor you buy it from, characteristics may vary.

Why do some strains grow faster than others?

Historically black market growers needed strains that would rapidly produce great yields so that they could optimise their production. This has led to the development of many fast growing strains that were bred so that they would grow and produce flowers faster than usual. The strains below were genetically designed to ensure a quick turnover and a good yield.

Many people ask if there is a difference between sativas and indicas? Sativas often take a bit more time than indicas to flower but we didn’t want to make this an indica only list so we dug around to find some fast growing sativa strains.
