Top 10 Best Indica Strains UK to Grow - 2021 UPDATE

Cannabis varieties Growing

Indica strains are beloved worldwide for their relaxing and sedative effects. Perfect for those with health issues, depression or insomnia, they’re the ideal end to an evening.

Short and stocky compared to Sativa plants, they often produce thick, resin products loaded with potent THC. Yet there are mellower CBD-balanced plants too.

There are plenty of Indica strains to choose from, including pure Indica options like Northern Lights and hybrid strains with dominant Indica profiles. Here we look at the top 10 best Indica strains in the UK and what to expect.

Why Indica strains are so popular in the UK

Indica strains are a long-term favorite in the UK. They tend to be the most popular because they induce relaxing and physical effects, rather than the more cerebral Sativa. The result: calming bliss.

That does, however, mean that you can’t expect to get much done on Indica. It’s a mood relaxer; not an energizer. Given how hectic modern British life can be, it’s no wonder these strains are favored.

Indica weed is an excellent treatment for anxiety, stress and depression. It’s also a fine treatment for headaches, inflammation or pain. In fact, UK growers have been behind some of the world’s most famous Indica strains.

Although the country at large has differing preferences, the following are the top 10 cultivars in the UK right now.
