Royal King Genetics — first-party test batch
Numbers below are from our internal seed-lot QC and verified grower submissions, not breeder marketing. Determined from a single batch tested 2026-04-10 on 100 seeds.
About Gutbuster Feminized
Gutbuster is a 77/23 indica testing at 22% THC with a myrcene-dominant terpene profile. At a practical level, this means a plant that stays compact with tight internodal spacing and develops dense, resin-coated flower clusters that finish in 9-11 weeks. The Myrcene/Caryophyllene combination shapes both the aromatic profile and the effect character — this is not a one-dimensional strain.
Growing Parameters
Flowering time: 9-11 weeks from flip. Indoor yield at 600+ PPFD: 400-500g/m². Outdoor in full sun with 5+ gallon containers: 400-600g/plant. Plant height indoors after training: Short-Medium (2-3.5 ft). Feed EC targets: 1.0-1.4 in veg, 1.4-1.8 in peak flower. pH range: 6.0-6.5 in soil, 5.8-6.2 in coco. Myrcene production peaks when day/night temperature differential exceeds 10°F in the final two weeks — growers who drop nighttime temps to 62-65°F during this window report stronger aromatic development.
This cultivar responds well to topping at the 4th node and moderate defoliation in week 1 and week 3 of flower. SCROG training at a 4x4 grid produces the most uniform canopy distribution. Rated intermediate difficulty.
Effects and Use
At 22% THC, Gutbuster delivers creative, energetic, calm effects with a myrcene-influenced character. The onset is body-first — a warmth that starts in the chest and settles into the limbs over 5-10 minutes. At moderate doses, you remain conversational and present. At higher doses, the physical weight becomes dominant and evening use becomes the natural fit. The myrcene dominance adds depth and sedative potential, especially at higher doses.
Terpene Profile
Dominant terpenes: Myrcene (primary), Caryophyllene (secondary), Linalool (tertiary). This combination produces an aroma profile that is immediately identifiable when the jar opens and translates well to both vaporization (best at 360-385°F) and combustion, though lower temperatures preserve the caryophyllene top notes that combustion destroys.
Who Should Grow Gutbuster
Best suited for growers who want control over their plant size and harvest timing — photoperiod genetics let you veg as long as you want before triggering flower. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results.
