About Kush XL Auto
The genetic expression of Kush XL — a 68/32 indica — varies meaningfully across phenotypes. Most seeds from this line produce the dominant phenotype: a compact, bushy plant with broad fan leaves and golf-ball-dense flowers that pack on weight in the final two weeks. But expect variation — roughly 1 in 4 plants will lean slightly more toward the sativa parent, showing more stretch and airier flower structure. THC testing at 17% across phenotypes, with Myrcene consistently dominant.
Genetic Expression in the Grow Room
The dominant phenotype — which appears in roughly 70-75% of seeds — produces a compact, symmetrical plant with broad internodes and heavy lateral branching. Fan leaves are wide and dark green, typical of the indica heritage. Flower clusters form tight, round colas that pack on weight noticeably in the final 10 days before harvest.
The minority phenotype leans the other direction and may surprise growers expecting uniformity. Flowering completes in 8-10 weeks across phenotypes. Yield: 350-450g/m² indoor, 500-700g/plant outdoor. Height: Tall (4-5 ft). Rated intermediate — the phenotype variation adds a layer of interest without adding significant difficulty. Growing from regular seeds with autoflowering genetics.
What Users Report
Kush XL at 17% THC produces relaxed, sleepy, happy sensations that users consistently describe as physically comforting without being immobilizing at moderate doses. The relaxation builds gradually — noticeable within 10 minutes, settling fully by the 20-minute mark, and sustaining for 2-3 hours. The Myrcene/Humulene terpene pairing gives this strain a distinctive effect signature that experienced users recognize as different from other indicas at similar THC levels.
Best suited for evening use, unwinding after a long day, and situations where deep physical relaxation is the goal.
Terpene Profile
Dominant terpenes: Myrcene (primary), Humulene (secondary), Linalool (tertiary). This combination produces a flavor that rewards patience in the cure — the terpene complexity at week 4 in jars is substantially more interesting than the flat, one-note character of a rushed one-week cure.
Who Should Grow Kush XL
This strain fits growers with at least one harvest behind them who want to step up in quality without dramatically increasing complexity. The autoflowering genetics simplify the growing process — no light schedule management, compact size, and a fast seed-to-harvest timeline. Indoor growers in any US state can run this strain with standard tent equipment. Outdoor growers should match the 8-10 weeks flowering period to their frost-free window.

Royal King GeneticsBred and stabilized in-house by Royal King Genetics — our internal breeding team. Every batch is QC'd and germ-tested above 99% before it ships. Read our full breeding process and about page.
Kush XL is our F5 autoflower line. Five generations of selection have fixed both the autoflower trigger and the purple expression the cultivar is known for. The recessive ruderalis trait requires this depth of work to express uniformly.
Lock the autoflower trait in Kush XL through five generations of selection.
Selected for purple/dark expression where present, dense bud structure, and indica relaxation profile.
