Sour Kush Auto

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.

The vegetative phase is unremarkable in the best possible way, steady, consistent growth with no drama in published cultivation reports. After topping at node 4, plants commonly bush out aggressively and fill a 3x3 space by week 5 of veg. The stretch after flipping is moderate, about 35-40% stretch that is easy to manage with a single round of LST.

Flowering completes in 60-70 days. Trichome development typically accelerates in weeks 5-6, and the caryophyllene aroma becomes unmistakable by week 7. Typical indoor yield: up to 450 g/m2 under LED. Height at harvest: Medium. Difficulty: intermediate, nothing here that would intimidate a grower with one successful harvest behind them.

The one thing to watch: the last two weeks before harvest commonly require dehumidifier support to keep RH below 50%, the flower density can trap enough moisture to raise concerns about bud rot in ambient humidity above 55%.

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.

Dominant terpenes: Caryophyllene (primary), Limonene (secondary), Myrcene (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.

Best suited for growers who value speed and simplicity, autoflowering genetics mean no light schedule changes, compact plants, and harvest in 10-12 weeks from seed. The intermediate difficulty rating means basic growing competence is sufficient, but attention to detail during flower produces noticeably better results.
