Blue Nightmare, bred by RNM Flowers, is a resinous, berry-flavored hybrid cross between Blue Dream and Tahoe OG (though there are conflicting reports from California of a Blue Nightmare strain that stems from Blue Dream and Blackberry Haze). As far as the RNM Flowers' offering, Blue Nightmare has trichome-covered buds and possesses the aroma of blueberries typical from the Blue Dream lineage. Blue Nightmare promotes mood elevation and relaxation.
