Note on neutrality: in Germany, advertising and any form of sponsorship for cannabis are prohibited (§ 6 KCanG). That is why this page has no buying recommendations, no shop links, no affiliate links and no discount codes. I accept no money and no free products from seed banks or breeders.

What you will find here is factual information: how breeding works, what technical terms on seed packs mean and what to look out for in genetic claims.

Why Honest Breeding Beats Flashy “White-Label” Marketing Packs

I learned the hard way how disappointing stale or unselected “white-label” bulk seeds can be: out of an expensive 10-pack from a major commercial seed bank, 7 seeds failed to germinate at all, 2 died after 2–4 days from depleted seed vigor, and the sole survivor had a completely different structure than advertised (full story here). That is why I Grow Pedia contains zero buy links or advertising – only transparent knowledge on real selection and seed preservation.
