Growing in the northern hemisphere can be challenging, especially in some areas of Europe where conditions can be cold, wet, and even frosty.

Luckily, thanks to expert breeding, there are a variety of cannabis varieties, that’ll still produce excellent results even in the most unforgiving northern climates. In this post we share a handpicked list of our top indica strains to grow in the northern hemisphere.


Before we begin looking at individual strains, it's important, that we understand the northern climate and what grow conditions we’re dealing with.

“Northern climate” is a term that loosely refers to any climate of the northern hemisphere. These conditions are very generalised by cold winters and relatively cool summers, but obviously vary between different parts of the northern hemisphere.

Regular cannabis depends on its photoperiod for flowering, and is also seasonal. That means, that northern growers will usually germinate seeds between April and May and collect their harvests between October and November.

One of the biggest concerns for growing in the north are cold weather and frost, both of which can have detrimental effects on the development of cannabis plants. While indicas are generally thought to be a bit better prepared for these conditions due to their origins (mountainous regions of India and Nepal), they still suffer in cold or frosty conditions.

It is important to realise, that we have painted a very general picture of northern climates here, and that conditions obviously vary between different geographical locations. Hence, it is really important you understand your local climate and how to prepare for it before beginning your grow op.


Below is a special list of our top 5 recommended indica strains for northern growers. Read on for more information about each individual strain and remember; for the highest quality cannabis seeds delivered direct to your door, order at RQS today.

1. Sweet ZZ

Whoever said quality cannabis couldn’t be grown in northern regions never met Sweet ZZ. This stoning indica prefers a warm climate, but barely even detects when things get a little cold. Sweet ZZ earned recognition in the cannabis world primarily for her fruity and zesty flavour, inherited from scrumptious parent strains Grape Ape and Grapefruit. As well as producing irresistible terpenes, her bulbous flowers churn out a THC content of 22%—nothing to be scoffed at! A few tokes sends a heavy wave of euphoria over every inch of the body.

Sweet ZZ performs well outdoors, even in the chilly air at the end of the northern growing season. She’ll stand strong at a height of 160–200cm and produce up to 550g/plant at the end of September. Indoors, she produces an equally impressive 600g/m² after an ultra-brief 7–9 weeks of flowering.

Candy Kush Express delivers a canopy loaded with flowers in as little as 7 weeks of flowering.
