Description from Fast Buds

Origins and Genetics

Crafted from multiple crosses of premium purple strains, this hybrid is renowned for its powerful growth from taproot to harvest. By blending our autoflower genetics with high-yielding, resinous purple strains, we've developed these potent C4 seeds. The male parent was noted for its short flowering time typical of sativas, while the female parent offered an impressive aroma, flavor profile, and high THC content with low CBD.

Taste & Aroma

With a subtle buttery undertone and deep earthy notes, C4 delivers a rich sensory experience.

Experience the High

Upon inhalation, the effects of C4 are immediate and immersive, spreading through the body like water soaking into paper. Within minutes, you'll feel a notable uplift in mood and overall well-being. The high is evenly balanced between the head and body, leaving you with a refreshing aftertaste reminiscent of a cool lemon sorbet on a warm summer day. This strain's effects can last for up to two hours of pure, joyful relaxation.

Medical Benefits

C4 is highly effective for managing headaches, muscle aches, anxiety, and stress, making it an excellent choice for those seeking relief through cannabis.

Growing Characteristics

C4 seeds reach maturity in approximately 8 weeks. During this time, you'll witness the development of its compact flowers, composed of soft green buds and orange pistils. By the second week of flowering, visible buds will begin to form and will double in size each subsequent week. The plant reaches its peak growth during the final two weeks of development, producing a dense central cola that resembles the holy grail of cannabis cultivation.

With a yield of up to 650 g/m² (1.4 pounds per light), this strain is ideal for both novice and experienced growers. C4 is resilient against pests and mold, making it well-suited for indoor, outdoor, and greenhouse environments. It requires minimal maintenance and offers a calming, tranquil experience for growers seeking a low-effort, high-reward plant.
