Top 10 fast flowering cannabis strains

Fast Flowering cannabis strains are quickly growing in popularity worldwide. But what are fast flowering cannabis strains? Well simply put, they are feminized photoperiod cannabis strains that produce the same amazing results, but in a much shorter time. 

Fast flowering cannabis strains are developed by crossing photoperiod and autoflowering strains. More precisely, a female clone of a feminized photoperiod strain is crossed with a feminized auto. This creates a strain that carries the autoflowering gene but still has the light-dependent characteristics of a photoperiod strain. This means that while the autoflowering genetics aren’t dominant, their presence leads to faster flowering times. The results are strains that can be harvested quicker, while still providing the high yields and high potency levels of traditional photoperiods.


So as you can tell the benefits of growing fast flowering cannabis strains are numerous. Here’s a list of the benefits of  these plants, that we think will really have you sold on growing fast flowering strains.

  • They have faster finishing times than normal photoperiods
  • They produce higher yields than autoflowers
  • This allows for more harvests each year
  • Lower indoor growing costs
  • Unlike autoflowering strains, fast flowering strains can be cloned

So now you know what they are, and the many benefits to growing them, here is our list of the Top 10 fast flowering cannabis strains available on the market:
