Lab Theory™ Sour CKS Caviar is 100% single-strain cannabis. Made from organic-certified flower in the Fraser Valley of BC, grown in a mix of living soil and then fresh-frozen within minutes of harvest. Lab Theory™ extracts all the Sour CKS goodness to retain the complex terpenes and cannabinoids of this cultivar. The result is a rich, golden caviar with a sweet and sour aroma.
