big bud from world of seeds, suppose to be mold and disease resistant, ive seen the auto version grown out with good results, did the strawberry blue myself from WOS with good results also so i think their beans are legit.

9 pound hammer, dr. Who, pennywise, and hurkle - tga seeds
Amnesia og, cotton candy cane, somari, dieseltonic, veneno
Anybody heard of red bee seeds? Looks like they have alot of strains resistant to PM... those are just a few i found, many more if u do the research, hope this helps my friend
