Alien OG is an out-of-this-world strain with a reputation all its own. Buds of Alien OG are packaged as small, nugget-like clusters. This strain has a surprisingly sweet, citrus-like smell, with notes of lemon wafting up from the cured buds. There are also more subtle notes of earth and fresh pine. When combusted, flowers give off a more spicy, hashy scent typical of the OG family.
