Power Nap feminized (Blue power x white nightmare) crosses Blue Power to White Nightmare: Blue Power - the plant Sin City have leaned on for over a decade against the plant that carried Sin City's name out of Nevada. Neither is a filler parent, which is why this pairing is worth a pack rather than a look. Sin City work from a small stable of proven house parents rather than starting fresh each time, which is why their crosses behave more consistently than the ingredient list alone would suggest.

Feminized, so the whole pack should run female. Growers with a fixed number of sites tend to want this one; breeders generally want the regular.

Order matters in a cross name. In Power Nap feminized (Blue power x white nightmare) the Blue Power side supplied the seed and White Nightmare the pollen, and the reciprocal - the same two plants the other way round - is a separate breeding decision with its own results.

Genetic Lineage

• Mother: Blue Power. The 2010 cross that everything else at Sin City was built on top of. Built from a Power clone crossed to a White Moonshine male in 2010; the Power side is given as Sour Double x Master Kush, and White Moonshine as The White x Blue Moonshine. The mother was bought simply as Power from Progressive Options, a Prop 215 shop in the San Fernando Valley that dealt in elite cuts, and a persistent rumour says it was really the cup-winning Sour Dubb. Nobody has settled that.
• Father: White Nightmare. The strain that first got Sin City noticed outside Las Vegas. Its own cross is Sin City give it as Blue Dream crossed to White Moonshine. The parentage is written two ways. Sin City's own product naming gives Blue Dream x White Moonshine, while several third-party listings give it as The White crossed to Blue Dream. Those are not the same claim - White Moonshine is itself The White x Blue Moonshine, so the second version drops a parent. The breeder's own statement is the one to go on.
• Why these two. They are not variations on the same idea. They pull in different directions, and that spread is what makes a pack worth hunting through rather than just growing.

Flavor and Aroma Profile

• The Aroma. Sweet kush over sour fuel, with a creamy berry note behind it.
• The Taste. Citrus and berry finishing earthy.

The two halves, side by side

• Two frames in one pack. Blue Power is indica-dominant, usually put around eighty twenty. White Nightmare is sativa-leaning, and a heavy resin producer. Decide which suits your room before you flip, because you get both.
• Opposite ends. Blue Power is reported as heavy on the body with the mood lifted rather than flattened; White Nightmare as energetic and cerebral. The cross sits somewhere between and moves plant to plant.

Cultivation and Growth Traits

• Plant Structure. The two parents disagree here, so plan for range. Blue Power is indica-led, in the region of eighty twenty. White Nightmare is narrow-leaf in build, and unusually resinous for it.
• Vegetative Phase and Training. Open the middle out early. Light reaching the lower sites is worth more than any late correction.

Effects and Experience

• The Mind. Growers describe Blue Power as heavy on the body with the mood lifted rather than flattened.
• The Body. White Nightmare is reported as energetic and cerebral, and that is the side supplying the weight here.
