There are several cannabis strains out there with the moniker of Ogre. The best known and most sought after is a sativa/Skunk-leaning phenotype of the multiple award-winning indica Sensi Star. While most phenotypes of Sensi Star are fairly compact indica plants, the Ogre is named for its much larger size and huge yields. Giant, frosty colas produce very high levels of THC and a pungent lemon-skunk aroma.
