well you can make almost any Strain Purple, just Put the weed (While Growing) in a colder place for about a half of day, and you well notice some purple. Allot of people well call it Purple Haze, or whatever simply because it has the color of purple in it.

that doesn't mean that it is true. in fact purple Haze was a type of Acid back in the Day, and the name came up when Jimmy wrote about it.
