I guess my question(s) would be why do it in the first place and why if you do it would you pick that strain?
 
If you are only trying to play Johnny Weedseed and populate the area with plants to grow wild and if you also will be growing yourself for your own consumption and or sales bringing down a lot of attention to your area/County by flooding it with plants will only increase the risk that people in the area will be looked at closely since they would be the ones most likely to do what you are talking about doing so that would put you at an increased risk.
 
If you do decide to do it anyway unless the price has changed for $78.40 (GBP) – ($127.04 USD) you can buy a pack of the original White Widow (Black Widow) and be spreading one of the most famous strains to ever be developed and one that has been used in numerous very successful crosses rather than paying slightly more for an unknown quantity/quality that may or may not be as described.
