The name of Sin City Seeds' indica-dominant hybrid, Happy Nightmare, may be an oxymoron that can leave users scratching their heads in wonder, however, it actually comes directly from the strain's parents - Happy Kush and White Nightmare.

Happy Kush was created by Karma Genetics by crossing Happy Brother and a San Fernando OG Kush back-cross. Sin City crossed that Happy Kush with their White Nightmare, a mix of Blue Dream and White Moonshine. This concoction makes Happy Nightmare about 60 percent indica. Tasting of menthol, berries and Kush the strain provides a creeping high that touches both the body and mind.

With a strong body buzz that can leave users fingers and toes tingling, it should be no surprise that Happy Nightmare can be potent pain medication. Those same effects can also soothe appetite crushing nausea. Its cerebral effects can ease anxiety and provide stress relief. The strain may also help with glaucoma, migraines and arthritis.

Happy Nightmare can be grown outdoor but does better inside as it is not entirely resistant to temperature fluctuations. If trying to grow in an outdoor garden it should be in locations where temperatures do not rise above 90 degrees Fahrenheit or fall below 45 degrees at night. Indoors this strain does best when kept between 66 and 74 degrees. Happy Nightmare plants may need support during the flowering period, which can last between eight and nine weeks.
