Seb's take
Citrus, pineapple and tropical fruit on the nose, with a sour, woody undercurrent. Easy to grow and quick to flower, she is strong enough that first-timers should approach as you would a staircase in the dark, and the high runs giggly, sociable and uplifting.
Where it comes from
Female Seeds worked from C99 on both sides, which is to say they stabilised the line rather than crossed it outward, a plant bred to breed true. The result is recommended, in the breeder's telling, to those with a fondness for landrace material, and the tropical, old-fashioned character bears that out. What you gain from the selfing is consistency: less lottery in the packet, more of a known quantity from one seed to the next.
Nose & flavour
A fruit stall of a nose, citrus and pineapple to the fore, tropical sweetness behind, with a sour note keeping it honest and a woody undertone anchoring the lot. Lively and layered rather than one-dimensional, and bright enough to fill a small space as she comes into flower.
The high
Giggly, sociable and uplifting, good company rather than a quiet corner. The breeder notes the THC can run strong, so a first-timer would do well to approach as you would a staircase in the dark. Bright, conversational, and better suited to daylight and company than to a solitary evening.
Growing it
Easy in her care and quick to flower, 56 to 63 days, which the breeder counts among her virtues. Indoors she keeps to 80 to 100cm and returns 500 to 600 g/m²; outdoors she stretches to 150 to 200cm and gives around 400g per plant. THC is listed at 15 to 20 percent. Forgiving of enthusiasm and undemanding of skill, she suits a home grower after a dependable classic without the fuss.
