RS11, also known as "RS-11" and "Rainbow Sherbert #11," is a hybrid weed strain that Deo Farms made by crossing the OZ Kush project Pink Guava with a Sunset Sherbert. RS-11 was bred by Deo Farms of Oakland, CA, the maker of Zoap. RS-11 was selected by Wizard Trees of LA, along with RS-54. 
In 2023, many cultivators grow RS-11 across the US. RS-11 is a potent hybrid.
