yeah i heard that mr nice is the strongest strain of weed so far its also called G-13 i beleive. Aparently it was developed by the goverment? The story I heard goes like this. The U.S. government has operated a research pot farm in the state of Mississipi since the 60's. Over time, the powerful agency's operated by the U.S. government (CIA, FBI, DEA, etc.) bought, and collected cannibis (clones and seeds) from every part of the world. All true breeding varieties (the most prized by breeders). Some one stole a cutting from a 100% indica that is a genetic masterpiece. Circulated underground and now the world.
