About Supergirl Feminized

We have run Supergirl 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 26% THC that matches the genetic promise. The 88/12 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 9-11 weeks. Trichome development typically accelerates in weeks 5-6, and the myrcene aroma becomes unmistakable by week 7. Typical indoor yield: 400-500g/m² 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: 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%.

Effects and Use

At 26% THC, Supergirl delivers relaxed, sleepy, 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 360-385°F) and combustion, though lower temperatures preserve the caryophyllene top notes that combustion destroys.

Who Should Grow Supergirl

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.

Lineage Notes

Leafly documents that "Nirvana Seeds created Supergirl by backcrossing the famous Skunk #1 and focusing on the indica characteristics of that strain's genetics," and its genetics diagram lists Skunk #1 as the sole parent. No second parent is documented, as the strain is a female backcross rather than a two-way cross.

Recommended US Climate

Cold-tolerant; performs well in short-season Northern states (ME, VT, MN, WI). Indoor cultivation works anywhere.
