Seed sellers in the US can get in a loooot of trouble for sales through the mail (compared to Spain, the Netherlands, Canada and the UK which all have unique laws that make it easier for companies to store and sell cannabis seeds legally). Unfortunately, you rarely see seed companies in the USA that last longer than a few months so it's hard for them to build a reputation - good or bad. That being said, I know at least one or two growers on here have ordered from an American seed bank and got their seeds successfully. Hopefully someone will chime in!
