Holy Grail is a hybrid cross between Kosher Kush and OG Kush #18. This top of the line hybrid strain is pretty much perfect all around. It has dense buds that are sticky with resin and covered in trichomes. The complex spicy aroma is as splendid and pleasing as the strain is potent. Holy Grail has tested over 30% THC and is one of the most potent strains in existence. The buzz produced is balanced and invigorating, this is truly the Holy Grail of Kush strains.
