Pepe Silvia R1 by Ethos Genetics

Pepe Silvia R1 is a heavy hitter that loads every branch with buds, from the top cola down. Ethos Genetics crossed Zweet OG #8 with Grandpa’s Cookies #6 to create a vigorous feminized photoperiod with kushy, gassy and citrus terpenes, a very heavy yield rating and TAC of 25-30%.

Medium in height with strong lateral branching and a heavy bract-to-leaf ratio, she produces dense flowers that trim easily. The effect is long-lasting and euphoric, and the 60 to 63 day flowering window keeps her practical for indoor rooms and outdoor gardens alike. For growers chasing weight and quality from Ethos seeds, Pepe Silvia R1 delivers both.

Lineage and Breeding: Zweet OG #8 x Grandpa’s Cookies #6

Zweet OG #8 represents the OG side of the cross, and its influence comes through in the kushy, gassy base of the terpene profile and in the plant’s vigor. The #8 tag marks a specific numbered selection chosen from a larger hunt.

Grandpa’s Cookies #6 brings the Cookies side, adding density, resin and a sweeter, citrus-tinged layer to the flavor. Combined, the two numbered selections produce a hybrid that balances OG power with Cookies structure.

The R1 suffix means Pepe Silvia is the first reversed-female feminized generation. A female was reversed to make pollen and crossed onto another female, so every seed is female. That gives growers a full, consistent canopy with no males to remove.

Aroma, Flavor and Effect

Pepe Silvia R1 hits the nose with classic kush and sharp fuel, brightened by lemon-lime and orange zest. An acrid, chemmy edge lurks underneath, giving the bouquet bite and depth. It is pungent and lingers in the air long after the jar is closed.

The flavor is rich and gassy, with earthy kush on the inhale and a clean citrus note on the exhale. Her resin-heavy flowers keep the flavor strong through a slow dry and cure.

Ethos classifies her as a classic hybrid with long-lasting, euphoric effects. Expect a bright, happy lift that carries on for a good while, settling into a relaxed body feel later in the session. She suits unhurried evenings and social sessions.

Growing Pepe Silvia R1 Indoors and Outdoors

Pepe Silvia R1 grows vigorously to a medium height, with medium to long internodes and strong lateral branching. Topping and LST help her fill a tent with even tops, and a SCROG net makes good use of her branching. Because she stacks flowers along the full length of each branch, a trellis is useful to support the weight.

Flowering takes 60 to 63 days. Yields are rated very heavy, and the dense, high-bract flowers trim quickly. Steady airflow and controlled humidity late in bloom keep the heavy colas clean.

She does well indoors, in greenhouses and outdoors where the season allows a 60-plus day bloom. Ethos rates her for intermediate and experienced growers who can manage her vigor and output.
