Indica vs sativa vs hybrid
Quick rule of thumb: indica = body relaxation, sativa = head energy, hybrid = both. It's a simplification — modern strains are mostly hybrids, and the effect depends more on the specific terpene profile than the indica/sativa label. But for shopping, the labels still help: if you want couch + sleep, lean indica. If you want focus + uplift, lean sativa. If you want in-between, lean hybrid.
