About A-10 Auto
We have run A-10 across multiple environments now, and what stands out is the consistency. Whether in a 3x3 tent under LED or a 4x4 with HPS, this indica delivers a myrcene-forward flower at 18-22% THC that matches the genetic promise. The 70/20 profile shows in how the plant structures itself, bushy, compact, eager to fill lateral space. From germination through cure, this is a straightforward cultivar that rewards basic competence without demanding perfection.
What Growers Typically Observe With This Strain
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 minimal, typically a 25-30% height increase.
Flowering completes in 8-10 weeks. Trichome development typically accelerates in weeks 5-6, and the myrcene aroma becomes unmistakable by week 7. Typical indoor yield: 400-500g/mΒ² under LED. Height at harvest: Compact (2-3 ft). Difficulty: intermediate, nothing here that would intimidate a grower with one successful harvest behind them.
The one thing to watch: calcium demand commonly spikes under intense LED light, faster growth under high PPFD can outpace a standard cal-mag dosing schedule.
Effects and Use
At 18-22% THC, A-10 delivers creative, relaxed, happy 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 360-385Β°F) and combustion, though lower temperatures preserve the caryophyllene top notes that combustion destroys.
Who Should Grow A-10
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.

A-10 is our F5 autoflower line. Five generations of selection have fixed both the autoflower trigger and the compact internode spacing the cultivar is known for. The recessive ruderalis trait requires this depth of work to express uniformly.
Lock the autoflower trait in A-10 through five generations of selection.
Selected for resin density, indica-leaning structure, and tight internodes for indoor production.
