RustyWhyte is one of the most unique varities out there. Community member PastyWhyte had an idea back in March 2014, to combine a leucistic variety and a rusty spore colored variety to hopefully get the desired phenotype of both. They decided to go with AA+ and Columbian Rust, and got to work. Many generations and 4 years down the line, in June 2018, they decided to start releasing the spores to the community! Through hard work and dedication, PastyWhyte was able to obtain the goal they started with, a leucistic cubensis that dropped rust colored spores.
