I saved the original packaging from the dutch passion seed company. My early growing 1974 was columbian/ mexican bag seed like everyone else. In 1989 a friend had a photocopied seed catalogue from dutch coffee shops and I ordered from that. The original seeds were Amstel gold, early bud and hollands hoop.
Since then, I just try to save the best examples of what I like in potency, structure and aroma. All regular seed. I never knew the names but I know the traits of the different landrace genetics. We are just playing with hybrids of the originals.
I categorize by short/tall, indica traits or sativa, aroma, colour and sticky. As with regular seed, not stabilized, you never know what you get but thats half the fun of growing. I bake my pot in muffins haven't smoked in 30 years so I like different strains so I don't become immune. The batch I am doing is short and sticky
heres a pic from 1975, i am in white tee. Also original packaging from 1989
