The 10 best cannabis autoflower strains

The birth of autoflower strains changed the cannabis industry forever. 

Growing autoflowering cannabis seeds made cultivating your own marijuana a whole lot easier. 

This opened the door for many new cultivators who were once too intimidated to try growing weed themselves.

But, what makes an autoflower strain different from a regular or feminized strain?

Well, an autoflower strain is:

  • Non-photoperiod – this means autoflowering marijuana isn’t dependent upon light cycles and therefore doesn’t need sleep when they grow. This allows autoflowers to flower faster.
  • Smaller than other cannabis strains – when you grow autoflower cannabis, you don’t need a lot of room. This allows growers to save money, time, and space in their home or dedicated growing area.
  • Resistant to pests diseases – while not wholly impervious, auto flowering strains are bred to be hardy plants.

Autoflower FAQs

What is the strongest autoflower strain?

The strongest autoflower strain is Auto Gorilla Glue #4 with a whopping THC level around 24%. If grown in the right conditions, this strain may even produce stronger weed than that.

Strains like Auto Black Jack are also extremely potent. We recommend that only experienced consumers choose these strains as their potency should be approached with caution.

Are autoflowers less potent?

Generally, no, autoflowers aren’t less potent. It’s a common misconception that autoflowers are less potent than feminized or regulars. 

This can be true in some cases, but it generally depends on how the plants are grown and also the autoflower strain that is grown.

How much does an autoflower yield?

It’s all down to the type of autoflower strain. Some autoflower strains can yield up to 21oz./m2 indoors. 

Autos are generally smaller than regular and feminized plants, so they generally yield less.

The myths surrounding autoflower yields are exaggerated, with some growers suggesting yields are extremely poor from autoflower strains. This isn’t true. 

What is the best light schedule for autoflowers?

Most growers give auto flower strains between 18-24 hours of light per day. Autoflowers are not photoperiods and therefore don’t need to sleep like regular and feminized plants do.

This trait allows autos to grow fast and flower automatically.

How often should you water autoflowers?

Autoflower plants should be watered every other day or every 3 days to keep them healthy and hydrated.

Do Autoflowers Produce Seeds?

Autoflower plants can produce seeds if you choose to breed them. Autoflower cannabis plants are perfectly capable of breeding and producing more autoflower seeds.

In general, autoflowers will most likely not produce seeds as they’re entirely feminized. While you can accidentally get a hermaphrodite plant, it’s unlikely.
