What Are the Strongest Indica Strains?

Indica strains are famous for their body high, sense of deep relaxation, and tendency to put you to sleep, but if you really want something to knock you out, it makes sense to go for the strongest indica strain. 

While the most potent indica strains don’t all have insanely-high THC levels (often used as a measure of potency), make no mistake—these are STRONG indica strains and should be consumed with caution, especially if you’re new to cannabis. 

Ready for an afternoon of couchlock or the best sleep you’ve ever had? This list of potent indica and indica-dominant hybrid strains will get you off to a “high” start!
