Strain Description
Big Z takes the sweet, fruit-heavy profile of Zkittlez and enhances its growth potential, resin production, and yield by crossing it with Runtz. This results in dense, trichome-coated buds that explode with tropical candy aromas, boasting deep purple hues, bright green accents, and thick orange pistils.
The effects start with an uplifting, euphoric rush, making it great for mood enhancement and creativity, before transitioning into a smooth, physically relaxing body high that doesn’t induce couchlock. The bold candy and citrus gas flavours ensure an indulgent, ultra-smooth smoke.
This strain is ideal for flavour chasers, extract artists, and anyone looking for a modern, easy-to-grow candy gas cultivar.
