This strain isn't just named after an action hero, it IS an action hero. Intense but not overwhelming, it allowed me to remain focused and productive throughout the ride.
As other reviewers have pointed out, it's worth noting that "Duke Nukem" should not be confused with "Nuken" which is a totally different animal and seems to be in wide circulation over the past year or so.
Before trying this strain, I would have thought that a pure sativa was most often going to make the best "daytime" experience. Now, I've got to say that this hybrid is far better than your average sativa for daytime. Again, there's an intensity about this strain but it comes off more as an energy boost and encouraging creative thinking. Definitely a favourite.
