I actually crossed Northern Lights female with Blue Cream male by accident then grew some of the seeds. It turned out to be quite good and very strong full body high. It will couch lock you but its a good feeling and happy. Very creative mood as well.
Two legendary strains, Blue Dream and Northern Lights, joined forces to create Blue Lights (aka Blue Lightning), an indica-dominant hybrid with a sativa/indica ratio of roughly 30:70. There are few public reports on the THC content of this plant, but it's said to create a very powerful body high. The effects are deeply sedating and euphoric, inducing a happy sleepiness coupled with creativity, energy, and mental focus. Blue Light's Blueberry genetics provide a pungent blueberry smell and a sweet berry favor. The buds have a dark green appearance with brown hairs. This strain is an effective choice for patients who want to treat anxiety, low mood, migraine headaches, nausea, physical pain, insomnia, and stress. But don't rely on it as the only form of treatment for conditions that require CBD, including severe epileptic disorders. Dry eyes and dry mouth are the only widely reported adverse effects with Blue Lights, though others may be possible. Bred mostly in Vancouver, British Columbia, this strain doesn't sell very well anywhere in the United States or Canada, on or off legal markets. It's definitely worth sampling for its lazy indica effects, but it isn't widely recommended as medication.
