Growing Characteristics

Flower Time
8–9 weeks
Yield (Indoor)
Heavy; dense uniform golf-ball nugs from top to bottom
Yield (Outdoor)
Heavy; performs well in both environments
Difficulty
Intermediate
Height
Medium-tall (3.5–5 ft) with extensive lateral branching
Environment
72–78°F day, nights dropped 5–10°F for purple expression. RH 35–40% late flower.

Grow Tips: Grows large with lots of branching — SCROG or double-layer trellis ideal as branches snap under dense bud weight by week 7–8. Top at node 4–5 and lollipop bottom third. #1 Stunna parentage provides PM/rot resistance superior to typical Runtz crosses, but extreme bud density still demands late-flower RH below 40%. Feed moderately. Silica strengthens stems for heavy buds. Full fruit/candy explosion emerges only after 3+ weeks of cure. Drop nights to 60–65°F for deep violet expression.

History & Origin

Represents Relentless Genetics' multi-generational breeding mastery. Prime Cuts Nursery pheno-hunted through wide variation to select this cut for exceptional candy flavor, potency, and the commercially significant dense bud structure that breaks the typical small-bud Runtz pattern.
