Hindu Kush is a pure indica strain native to the Hindu Kush mountain range; which stretches 500 miles between Pakistan and Afghanistan. This strong Indica’s THC percentage varies between 14% and 20%. Hindu Kush evolved into a hardy resinous plant in order to survive the harsh Hindu Mountain range. This makes it easy to cultivate and a great strain for producing hash. Hindu Kush has a sweet, earthy aroma and is great for pain relief and insomnia.
