MR. Nice Seedbank sells "Black Widow," Shantibaba supposedly was the creator of WW ! He split from some European breeder, and took the genetics to Mr. Nice.  He renamed the strain "Black Widow"! IMO the WW strain has gone the way of a lot of strains that were real good strains back in the 70-80's ! It may still be a good strain, but nothing like the first WW strain !!! I grew Mr. Nice's BW 10 years ago, and I wasn't impressed. It was OK, but it certainly wasn't what the original WW was !!
