Cannabis strain comparison
Northern Lights vs Blue Dream
Indica and sativa are the two traditional cannabis classifications. Indica cultivars (Afghan/Hindu Kush lineage) tend to be shorter, broader-leaved, faster-flowering, and more body-relaxing. Sativa cultivars (equatorial lineage) are taller, narrower-leaved, slower-flowering, and more cerebrally stimulating. In 2026, the indica/sativa binary is increasingly understood as a rough generalization rather than a strict pharmacological divide.
