Check this thread for general seedbank reviews.
If you’re in the US, I’d go with James Bean Co. Love them. Crazy fast shipping, good selection from great American breeders, and nice freebies.
This other thread has some OG sponsor links to trusted seed banks, and a couple bucks gets kicked back towards OG upkeep and you’ll be a good person.
You can also check out the Sponsored section to see the offerings from seed banks and members. My Fleur Du Mal babies are happy and healthy, but you’ll have to consult other threads to see how they look when they grow up (hint: awesome).
