What Is THCA Flower?
The Real Thing • Straight From the Plant

THCA is THC in its natural, unheated form. The moment you smoke, vape, or combust it, it converts to active THC — the same experience you expect, fully legal under the Farm Bill. GreenRX™ Sauk City carries exotic and craft THCA flower sourced for real potency, real bag appeal, and real terps. Every batch third-party lab tested.
