Black Rainbow© Autoflower – Citrus Eclipse Delight

By Seedstockers
Black Rainbow Autoflower is a striking, fast-finishing auto that blends (Watermelon Zkittlez × Bacio Rainbow) with Apollo Black Cherry Auto lineage, bringing citrusy brightness and dense, frosted buds in a compact, grower-friendly frame. Seedstockers highlights its “super frosty golf-ball colas” and “extremely citrusy aroma,” promising flavorful yields wrapped in high visual appeal. Popular among growers who value both speed and showmanship, Black Rainbow Auto finishes crisply yet projects bold color and terpene intensity. It’s an autoflower that delivers pleasing fruity zest, resin-drenched structure, and modern, cultivar-forward bag appeal—plus reliable performance in a short life cycle.

Cultivation Details

Black Rainbow Autoflower typically completes in around 9–10 weeks from seed, making it an excellent pick for tight schedules and quick rotations. Indoors, an 18/6 light schedule, early light LST to open the canopy, and moderate feed will coax wide, thick colas full of trichomes. The strain stays relatively compact, though moderately thick foliage benefits from some mid-flower defoliation to improve airflow. Outdoors, it handles sunny spots and subtle seasonal swings well, showing vivid bud coloration in slightly cooler bloom temps. Its structure is forgiving and consistent, delivering quality over repeats without excessive inputs—a blend of performance and simplicity that Seedstockers curated for modern cultivators.

Effects

Seedstockers lists this as a high-THC experience in the auto lineup (“high” band), delivering a clear, balanced effect—bright, slightly euphoric, and easygoing in feel. Upon first inhalation, users report a tangy uplift that nurtures mood and focus, gradually settling into gentle physical ease without clouding clarity. It’s approachable for daytime or early evening enjoyment, offering smooth transitions rather than abrupt shifts. Black Rainbow Auto bridges the energetic and the serene, making it a versatile favorite.

Flavor & Aroma

Flavor plays a starring role here. The aroma bursts with sharp citrus—lemon and lime zest—with a thin ribbon of sweet tropical fruit. Seedstockers calls it “extremely citrusy,” and that rings true on sniff. On the inhale, expect bright candy-like citrus that softens into juicy melon and tangy candy on the exhale. A delicate green freshness underpins everything, keeping the profile vibrant rather than syrupy. It’s a clean candy-citrus perfume that dazzles.
