Holy Grail Kush is a cross of multi-award winners OG #18 and Kosher Kush so no wonder it instantly won the 2011 High Times Cannabis Cup in hybrids category. In fact, this could be the Holy Grail you always looked for. The dense buds of Holy Grail Kush have a pungent citrus scent and can be harvested after a flowering period of 9 to 10 weeks. Its THC level over 20% is the guarantee for the complete relaxation provided in a happy combination with an euphoric state of mind. It also has beneficial effects on intense pains, anxiety, nausea, lack of appetite, stress and insomnia.
