The internet seed trade is split between breeder-owned shops and multi-brand marketplaces. Buying sativa seeds online directly from the breeder guarantees fresh stock and accurate strain information, whereas large marketplaces offer wider selection, frequent promotions, and consolidated shipping for several brands in one parcel. Marketplaces may hold inventory for longer, which can slightly affect viability. Each model suits a different kind of buyer, depending on priorities like price, variety, and freshness.
