With THC levels at over 20% this indica-dominant hybrid is one of the most potent strains on the market. Its no surprise this 40:60 sativa/indica hybrid is the offspring of OG #18 and Kosher Kush, both award winning stains, and Holy Grail Kush almost won a perfect score at the 2011 High Times Cannabis Cup. Despite it�s potency level this strain comes on more mellow and offers a deep euphoric sensation, perfect for treating anxiety, cramps, nausea, nerve pain, chronic bodily pain. Despite this, Holy Grail Kush has low CBD levels, below 1%, and shouldn�t be used to treat conditions such as seizures, or other health issues that respond to CBD. With a strong, and pleasant citrus aroma this strain is an excellent option.
