Crop King Seeds vs Royal King Seeds USA — Side-by-Side Comparison
Crop King Seeds is a Vancouver-based seed bank that has served US customers via international mail for nearly two decades. The brand is well-known, the catalog is reasonable, and the genetics quality is competitive. The persistent downside for American growers is the simple fact of border crossing: Crop King ships out of Canada, and Canada-to-US international parcels travel through customs, take longer, and occasionally get held or seized. Royal King Seeds USA exists to solve that exact problem — same kind of catalog, sourced and shipped entirely within the United States.
