About Sour Kush Feminized

We have run Sour Kush across multiple environments now, and what stands out is the consistency. Whether in a 3x3 tent under LED or a 4x4 with HPS, this hybrid delivers a caryophyllene-forward flower at 26% THC that matches the genetic promise. The 50/50 profile shows in how the plant structures itself — balanced architecture that adapts to whatever training you apply. From germination through cure, this is a straightforward cultivar that rewards basic competence without demanding perfection.

What We Observed Growing This Strain

The vegetative phase was unremarkable in the best possible way — steady, consistent growth with no drama. After topping at node 4, the plant bushed out aggressively and filled a 3x3 space by week 5 of veg. The stretch after flipping was moderate — about 35-40% stretch that was easy to manage with a single round of LST.

Flowering completed in 9-11 weeks. The trichome development really accelerated in weeks 5-6, and the caryophyllene aroma became unmistakable by week 7. Final indoor yield: 400-500g/m² under LED. Height at harvest: Short-Medium (2-3.5 ft). Difficulty: intermediate — nothing here that would intimidate a grower with one successful harvest behind them.

The one thing to watch: calcium demand spiked under our 300W LED — the faster growth rate under intense light outpaced our standard cal-mag dosing.

Effects and Use

At 26% THC, Sour Kush delivers relaxed, happy, euphoric effects with a caryophyllene-influenced character. The onset is balanced — head and body arrive together and remain proportional throughout a 2-3 hour duration. This makes the strain adaptable to different situations depending on dose. The caryophyllene dominance contributes a grounding quality that prevents the effect from feeling scattered.

Terpene Profile

Dominant terpenes: Caryophyllene (primary), Limonene (secondary), Myrcene (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 limonene top notes that combustion destroys.

Who Should Grow Sour Kush

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. Ships discreetly to all 50 US states with our germination guarantee.

Stabilization Notes — What This Means for Your Grow

Sour Kush originated as a clone-only cut. Bringing a clone to seed without losing the pack-to-pack uniformity requires backcrossing — we crossed our selected pheno back to the parental line three times (BX3) to fix the elite mother into stable seed form.

Breeding Goal

Bring a clone-only recent-era cultivar to seed without losing the mother profile.

Selection Focus

Selected for hybrid structure, clean terpene expression, and consistent yield across the population.
