The breeder of Holy Grail OG used The OG #18 (3-time cannabis cup winner) and Kosher Kush (2-time
cannabis cup winner) to create a strain that definitely lives up to its name. HGK is the holy grail of indicadominant varieties. It has a deep and complex flavor of coffee, Kush, hash and lemon/lime with a similar
aroma. These buds are very large, dense and have a slight bluish hue to them.
