Northern Lights Auto Feminized Seeds (Herbies Seeds)


Northern Lights Auto Strain Info

Northern Lights Auto was bred by Herbies Seeds to create a cultivar that can be grown at any time of the year without compromising on the potency that its award-winning mother plant is known for. This strain is highly adaptable to all environments and requires very little maintenance, making it especially easy to grow and perfect for novices.


This heavy-Indica hybrid (80% Indica/20% Ruderalis) is a result of crossing the Northern Lights strain with a Ruderalis to add auto-flowering properties. The original Northern Lights has its origins in indigenous Afghani strains – this is where it got its calming effects, strong body high, and exceptional vigor. This world-famous strain has given rise to numerous other varieties that became popular in the cannabis world.

Flowering Time

You’ll need from 70 to 80 days to nurture your Northern Lights crop from germination to harvest. In case you think the wait isn’t worth it, the yields will prove you wrong.


Northern Lights Auto will reward you with a harvest of 550-650 g/m² (1.8-2.13 oz/ft²) if grown indoors. Outdoor yields can reach up to 200-300 g (7-10.5 oz) per plant.


With this marijuana strain, you’ll get everything a good Indica is cherished for: full-body relaxation accompanied by a blissful, euphoric head high that will melt any stress and anxiety away. Northern Lights is recommended for nighttime use, as it grants a heavy but happy couch lock and helps you to get a good night’s sleep.

For Sleep

Medical Properties

Northern Lights Auto is said to help users ease chronic pain and offer relief from stress and anxiety. It can also be used to help combat insomnia and loss of appetite. If you’re having trouble eating or sleeping well, you might want to see some Northern Lights in your room too!

THC Levels

Just like its photoperiod mother plant, Northern Lights Auto features high THC levels that typically test at 16-23%, with little to no CBD.

Smell and Taste

This strain produces resinous and intensely flavored buds that sport a rich, sweet, fruity smell and taste with earthy pine notes – that’s a delicious smoke in our books!


Grow Tips

Northern Lights Auto is a very tough autoflower with superb resistance to harsh climates when grown outdoors. It’s easy to grow and maintain and also boasts good resistance to mold and pests, which makes it ideal for beginner growers.

In true Indica fashion, Northern Lights Auto plants are short and bushy. Indoors, the plants grow to a medium size of 90-110 cm (3-3’6), while outdoor crops reach up to 130 cm (4’3) in height.

  •  The plants don’t like high levels of nutrients. You may want to use lower levels of slow-release plant food instead.
  • It responds incredibly well to the Sea of Green (SOG) method.
  • Throughout the flowering stage, make sure to remove some light-blocking fan leaves so that the buds get maximum light.
  • It’s recommended to start flushing 2 weeks before harvest to remove any remaining nutrients from the growing medium.
