Herbies sells other seed banks' genetics rather than only its own. Their about page puts the catalogue at more than 1500 strains from 99 seed banks, and says they have been doing it for over twenty years. They do not give a founding year, so none is stated here.
They also breed. Herbies Seeds is their own bank, alongside AlphaFem Seeds, EGS and Seedkeepers, so part of the catalogue is their own genetics and the rest is other people's.
The shop indexed here is Herbies USA Express, which they describe as a branch set up for the United States. It ships worldwide all the same: their shipping page names UPS to European countries at 4 to 7 days and the UK at 4 to 8.
