RAINBOWS AT NIGHT (ZKITTLEZ X WHITE NIGHTMARE) fem puts Zkittlez over White Nightmare. One is Grape Ape crossed to Grapefruit, and the modern benchmark for candy terpenes; the other is the sativa half of Sin City's house stock. Two very different plants, and the point of the cross is what sits between them. The known parent is doing real work here - it is what turns an interesting pairing into a line that comes out the same way twice.
These are feminized. Every seed should come up female, so there are no males to find and pull and nothing to lose half a tent to. That is the pack to buy if you want a crop out of it rather than a breeding project.
Zkittlez sits on the seed side here, White Nightmare on the pollen side. If you have seen these two names paired the other way round, that is a different pack and not this one.
Genetic Lineage
- Mother: Zkittlez. Grape Ape crossed to Grapefruit, and the modern benchmark for candy terpenes. It traces back to Grape Ape x Grapefruit.
- Father: White Nightmare. The sativa half of Sin City's house stock. Built from 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.
- What to expect across a pack. Two distinct parents means real variation in frame, finish and nose. Select early and take cuttings off anything you would want again.
Flavor and Aroma Profile
- The Aroma. Sweet tropical fruit - the candy nose the name promises.
- The Taste. Tropical candy and berry.
What each side brings
- What to budget. The documented side, Zkittlez, runs eight to nine weeks indoors, reported elsewhere at nine to ten. Set the room to that and let the plants correct you.
- Two frames in one pack. Zkittlez is compact with tight internodes and thick fan leaves; glassy buds under a wet-looking frost. White Nightmare is sativa-leaning, and a heavy resin producer. Decide which suits your room before you flip, because you get both.
- Opposite ends. Zkittlez is reported as even and settled; indica-leaning; 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. Zkittlez is compact with tight internodes and thick fan leaves; glassy buds under a wet-looking frost. White Nightmare is narrow-leaf in build, and unusually resinous for it.
- Training. Worth the effort early - it is the difference between an even canopy and three colas and a lot of leaf.
- Flowering Time. Zkittlez runs eight to nine weeks indoors, reported elsewhere at nine to ten. Start checking trichomes a week before you expect to be ready.
Effects and Experience
- The Mind. Growers describe Zkittlez as even and settled; indica-leaning.
- The Body. White Nightmare is reported as energetic and cerebral, and that is the side supplying the weight here.
In the pack
7 feminized seeds per pack. Seeds from Sin City Seeds. The house style is a modern flavour plant crossed onto a stable Sin City male, which is why their releases hold together better than most crosses chasing the same trends. Original Sin City Seeds genetics.
