Throwback Thumper Auto

Throwback Thumper is an F1 feminised automatic from Mephisto Genetics pairing Old School Mango Haze with Sundae Thumper. The breeder lists it as 25% indica / 75% sativa and describes a profile of sweet, creamy, fruity and hazy notes. As with Mephisto’s new‑format Limited Editions, this line was released untested beyond germination and QC checks and sold in 5‑seed packs before being archived. Brand pages link COAs for this SKU, and independent lab summaries report THC around 18% for sampled lots. Growers familiar with Sundae Thumper can expect a similar seed‑to‑harvest window of roughly 75–85 days from sprout. Expect a sativa‑leaning structure and aromas that skew sweet and fruity with a light floral haze character.
