Look into white label seeds I have done their white skunk and white diesel in the past. I only just found out last year that someone mentioned they were actually a discount seed company affiliated with sensi seeds. I did their gear prolly about three years ago. I believe one in this community said hes running some white skunk and he was really impressed with it. They have white widow regular and feminized fyi. Best of luck with your search.
I grew some green house seeds white widow outdoors. Biggest plant I've ever seen with fluorescent pink hairs all over is from the frost...amazing smoke
The black widow must be superb cause I know the knockoff greenhouse version was a very nice plant imo from exp. tried several type genetics and the widow still is up there at the top section of my suggestions.
