Pro secrets
The secret to unlocking the full potential of Jack Flash lies in temperature control. To preserve its delicate Pinene terpenes, vaporize at 356°F (180°C) rather than combusting. This triggers the entourage effect, blending its 17% THC with secondary cannabinoids. Because of its clean, uplifting energy, it is the perfect companion for your morning coffee or creative brainstorming sessions. Beginners should start with a single inhalation due to its fast-acting onset, while seasoned users can appreciate its deep, multi-layered terpene depth.
