I had six White Widow that survived my "care" last year. I knew zip about growing -- thats why im here now. I live in nova scotia, set them out mid may and cut them near end of october. I dont know if they survived because they're really tough or it was just plain dumb luck.
A pal grew S Diesel last year and did really well with it , he's an old hand tho so he knows how things should be done.
