Grapefruit Romulan: 1000mg | Hybrid | 90.525% THC This strain is a descendant of the popular strains Romulan and Grapefruit. They combine to create a strong strain with both mental and physical effects.

The high is calming and focused, with a mood boost, increased sociability, and physical relaxation, as well as a strong case of the munchies. Romulan Grapefruit, not surprisingly, has a strong aroma and flavor of grapefruit.
