This hybrid is a cross of Romulan and Grapefruit. Grapefruit Romulan, not surprisingly, has a strong aroma and flavor of grapefruit, together with cheese and apples. Its effects are both relaxing and euphoric and it grows like a grapefruit in size. Definitely an excellent strain for true “couch-y” relaxation.This hybrid is a cross of Romulan and Grapefruit. Grapefruit Romulan, not surprisingly, has a strong aroma and flavor of grapefruit, together with cheese and apples. Its effects are both relaxing and euphoric and it grows like a grapefruit in size.
