Description

Ethos Genetics built Sour G R1 on a foundation of Jet Fuel Gelato crossed with a Sour D and Marshmallow OG pairing, a lineage that reads like a blueprint for complexity. The aroma opens with sharp fuel and pine before softening into sweet, floral undertones that linger through the cure. Effects sit firmly in high-THC territory at 16 to 24 percent, producing the kind of cerebral, energizing onset Sour D fans will recognize, rounded out by the creamy depth Gelato genetics tend to contribute.

Sour G R1 is a feminised photoperiod variety, meaning every seed in the pack is a productive flowering plant waiting on your light schedule to trigger the transition. The 9 to 11 week flowering window is worth planning around carefully: dialing in the longer end of that range often rewards growers with fuller terpene development and a more complete maturation of resin. Structure will reflect the hybrid nature of the cross, expect vigorous stretch during the transition to flower, so topping or low-stress training early keeps canopies manageable indoors. For cultivators ready to invest a full season in something genuinely interesting, Sour G R1 is a worthy project.
