This award winning hybrid is the offspring of hybrid OG#18 and Indica plant Kosher Kush, which is why it isn't surprising it packs upwards of 34% THC on average testing. The buds of Holy Grail are large and dense, appearing a brownish color or as a light green, featuring a bluish tinge to it sometimes. The plant itself is of medium height, with a small amount of leaves. The effects are more similar to a smooth relaxed type of buzz, with you feeling happy, upbeat and ready to be creative after smoking it.
