I don't know about outside, but I know from seed some of them are done at eight weeks while others have taken ten from the swith of 12/12. I think they would do well outside as they aren't too dense for mold to be an issure. I am going to run a couple of different cuts of it outside in the Midwest this year to see how she does. Goodluck!does anyone no when this strain would mature in the northeast from experience
