You ever tried medusa.ca? He has an impressive list of beans.Being in Canada my first go to place is GTA Seeds. Glad they have reopened.
Use True North to...only when they have sales though.
Xotic seeds I have bought there to.
Greenpoint seeds I have got seeds from.
Cannaventure I have got seeds from but rusty from there doesn't replace immature dead seeds so buyer beware on that.
There is a few places in usa that have a good track record with different breeders from usa but I try to always buy in Canada first...mostly because of the money exchange between usa and Canada dollar. So I do miss out on some gems from the usa...but if I want them bad enough I will buy from usa.
