ok so its like that: every strain on that website is called for example KGM ( K Green Malay) or FGS ( F Green Strain) the first letter is for the different farmers and vendors in south east asia and the other letters for the strains. i dont know if they have an english website but if not let google translate it. i would buy KGM, FGS, FRS, QUG, ARBN. with every 100g they send out samples with it and you can test the strain without opening the 100g bag. so i would buy these 5 - each one 100g.
