Top 10 fast growing 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! Some growers are looking for the fastest growing strains so they can have a fast turnover in their tent. Strains with a short flowering time are often autoflower or feminized seeds but not all of them flower at the same rate. To help you out we’ve created a list of the best short flowering – fast growing strains. Don’t hesitate to reach out if you know of any other strain that should be on this list 🙂 

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.

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.

Lowryder was developed through the mix of the two top selling indica strains, Top 44 and Early Special, which both have a rather short flowering period. This has resulted in a strain that flowers in just 6 to 7 weeks with a generous yield of up to 200 / 300 (g/m²). This strain is perfect if you’re looking for a ‘quick grow’ and don’t want to sacrifice your yield for rapidity.
