i know Muddy (i have been years ahead on other breeders) but i have a lt of auto haze types and crosses all selectted for years for bigger type of auto and like you can see they are bigger (look picture down 100% auto SDH)
now some seedsbanks like stitch wanted smaller types of auto's? so i had also some seeds from Dieselryder X auto SDH i put those up and selected the most smaller types and cross the males back too some smaller auto SDH
and from those seeds i selected smaller till F2 and thats SDH short pheno
