#1 Stunna

#1 Stunna from Relentless Genetics is a cultivar that wears its breeding goals on its sleeve: vivid color from the first week of flower, elite terps inherited from the Rozay line, and the structural vigor of In House Genetics' Twisted Velvet. The cross was created by selecting a colorful Rozay male with proper architecture and pollinating Twisted Velvet (Velvet Cookies x Purple Hulk), a mostly-indica frame known for dense trichome coverage and sturdy stems. Now in its third generation (F3), the line has been refined for consistency in color, flavor, and growth habit—though the F1 and F2 still offer interesting pheno-hunting territory for breeders.

Structurally, growers report phenotypic variation ranging from short, compact bushes to taller plants that stretch a bit more during the flip. The breeder describes stretch as "less than double," and the 420 Magazine seed-to-harvest journal from user JayMiami1221 confirms substantial but manageable stretch in early flower—"couldn't tuck them faster than they grew." Tight node spacing during veg is a consistent trait across phenotypes, translating into multiple bud sites per branch. The indica-leaning architecture (minimal internodal spacing, sturdy stems) responds exceptionally well to topping, LST, and SCROG setups. For commercial applications, the natural branching habit and uniform canopy development make this line preferred over Relentless' similar 5*Stunna, which runs shorter with less lateral spread.

Flower time sits comfortably at 56–63 days for most phenotypes. The Twisted Velvet-leaning phenos tend to finish fastest (56–60 days), while straight Rozay expressions push closer to 63–65 days with slightly larger flowers. The breeder states "most plants are done in 8–9 weeks," which grower reports and seed bank data consistently confirm. Neptune Seed Bank lists 60–65 days for the F3 specifically.

On media and nutrients, the documented 420 Magazine grow used Fox Farm Ocean Forest in 6.6-gallon pots with Canna Terra nutrients, Power SI (regular and bloom), fish sh!t, Recharge, Great White mycorrhizae, and Tribus Bloom—all delivered through a Blumat drip system. The grower also incorporated Power SI foliar feeds biweekly and Lost Coast Plant Therapy every three days through week 5 of veg for IPM. This is a strain that performs across media types: coco-perlite blends (70/30) with frequent fertigation, living soil builds, and standard peat-based mixes all appear in grower documentation. The F3 generation shows improved uniformity regardless of chosen medium.

For environment, #1 Stunna performs well both indoors and outdoors, tolerating hot, temperate, and cool climates according to Strainly listings. Indoor growers should target standard VPD ranges and keep humidity below 50% from week 4 of flower onward—though the strain's noted resistance to bud rot and powdery mildew provides a buffer that many cultivars lack. The 420 Magazine grower powered the cycle with an HLG 650R Spec Diablo with UVA supplement, and the results speak to the strain's ability to handle high-intensity LED light. For outdoor cultivators, harvest falls in early to mid-October in the Northern Hemisphere.

Color expression is the crown jewel of this line. Pink, red, and purple phenotypes dominate, with some plants coloring from the very beginning of flower while others transition around week 6. The F3 generation was specifically selected for early-onset coloration—the breeder notes that all mothers and fathers used to create the F3 were "red/pink/purple from the start of flower." Dense buds are generously coated with trichomes, giving a frosty, sugary appearance. Bright orange pistils thread through the calyxes, contrasting against the dark purple and deep green base colors. The calyx-to-leaf ratio is favorable for trimming.

The terpene profile is where Rozay's legacy shines brightest: berry fruit roll-up, red wine, and Flintstone vitamin notes dominate the nose. Neptune Seed Bank adds "sweet cream, tropical funk, gas, and candy diesel" depending on the specific phenotype. The dominant terpenes are Myrcene, Limonene, and Caryophyllene, with some phenos expressing earthy spice or gassy undertones. THC testing ranges from 20–26% across phenotypes.

For pest and disease management, the breeder's built-in resistance to bud rot and powdery mildew is a significant commercial advantage. Testers confirmed bud rot resistance across indoor and outdoor environments. The documented grower used Lost Coast Plant Therapy as preventive IPM through late veg—a sensible protocol given the density of the flowers in late bloom.

No specific wash/hash data has been published for #1 Stunna, but the strain's heavy trichome coverage and "resin performance" branding from Relentless suggest strong potential for solventless extraction. Neptune Seed Bank specifically notes the F3 is "flavorful enough to shine in solventless extraction." The dense, frosty bud structure with high calyx-to-leaf ratio should translate well to ice water hash processing.

For drying and curing, the tight, dense bud structure means standard low-and-slow protocols apply: 60°F, 55–60% RH for 10–14 days hang dry, followed by jar curing. The density of these flowers warrants extra attention to airflow during drying to prevent internal moisture pockets.

The prized #43 phenotype has been singled out by the breeder for future feminized S1 production and crosses, signaling it as the line's most elite expression. #1 Stunna genetics have already been used to create Queen of the South (Trop Cherry x #1 Stunna) and other well-known Relentless cultivars, cementing this strain as a foundational breeding piece in the Relentless catalog.
