when people talk about different strains working for different problems i agree totally 100%. However here in England and im sure its the same in most parts of the world we dont have the luxury of a menu, and a choice of which strain works for what. Unless you grow your own or try over a 100000 different strains your never going to know which suits you. You could be lucky and grow your own and experiment or know a grower to chat with im sure the many growers here will tell you which is good for what but to get that strain you have to grow yourself.
