Autoflowers are a compact, fast flowering cannabis variety that grows to around 100cm tall and can be ready to harvest in as little as 8 weeks. They flower based on age as opposed to light which means there is no need to mess around with different lighting schedules when you grow them. Autoflowers are all ordinary strains that have been crossed with cannabis Ruderalis, this makes them naturally robust and able to handle cooler climates more comfortably compared to photoperiod strains.


Autoflower seeds are like the Swiss army knives of cannabis plants; compact, reliable and come with a whole stack of added benefits. So, why might you want to buy autoflower cannabis seeds for your next grow?

Autoflowering Seed FAQ’s

Are autoflowering cannabis seeds feminized?

Yes, all of our autoflowers are feminized which means they will produce 100% female autoflower plants.

How long does autoflower cannabis take to grow?

The life cycle of an autoflower is shorter than a photoperiod taking just 8 to 12 weeks to grow from seed to harvest. Sativa-dominant autoflowers tend to take around 12 weeks whereas Indica-dominant autos take to 8-10 weeks to fully grow.

How much can an autoflowering strain yield?

An average sized autoflower yield is between 1-3.5 ounces per plant (30-100 grams). However, the yield of a plant varies widely depending on genetics, growing conditions and environment. In the right conditions and given some LST training some of our super autoflowers such as Auto Pounder can produce up to 5 ounces (150 grams) per plant.

Are autoflowers less potent?

Historically autoflowers have always been thought of as the less potent strains. However, now autoflowers can produce THC levels over 25% and rival the potency of many photoperiod varieties.

What is the best light cycle for autoflowers?

The best light cycles for growing autoflower seeds are 18/6 or 20/4. This allows them to absorb plenty of light while still providing some darkness to rest.

What triggers autoflowers to flower?

Autoflower cannabis plants flower based on age. At 3 to 4 weeks from seed they will begin to flower automatically irrespective of their light schedule.

How do you know when an autoflower is ready to harvest?

During the final few weeks of the flowering stage, you should start to monitor the trichomes of your plant using a magnifying glass to help you identify the signs of maturity. The pistils will begin to darken and curl in and once around 60-70% of the trichomes have turned a cloudy color they are ready to be harvested.

Are autoflowering seeds easier to grow than photoperiods?

Yes. Autoflower plants grow to around 100cm tall making them much easier to grow indoors. They also flower automatically, which takes the hassle out of requiring different lighting schedules. Plus given their tough ruderalis backgrounds, autos are hardy plants that can withstand growing outdoors or indoors in a variety of climates.
