Description
C4 Auto Feminised is a balanced indica-sativa hybrid from Fast Buds, bred for growers who want a capable autoflowering cultivar with serious cannabinoid depth. THC runs between 16 and 24%, complemented by a medium CBD content in the 1 to 5% range, a combination that produces an experience with both weight and clarity. The overall character leans toward grounded, relaxing effects with enough sativa presence to keep the mind engaged.
As a feminised autoflowering variety, C4 Auto removes much of the guesswork from the cultivation cycle. There are no males to cull and no light schedule to manage, making it an accessible choice for indoor growers working with tents or limited space, and a reliable performer for outdoor cultivators in temperate or variable climates. The autoflowering genetics keep the plant compact and the timeline efficient from seed to harvest. Fast Buds has a consistent track record with autos, and C4 is a straightforward entry point into their catalogue for growers at any level.

FAQ

about this product
C4 Auto from Fast Buds brings high-THC potency and a broad cannabinoid profile to an easy autoflowering grow, everything you need to start confidently.
It's genuinely one of the more forgiving options on the market, designed with beginner growers in mind. As a feminised autoflowering variety, there are no male plants to identify and remove, and no light schedule to manage — the plant moves through its cycle on its own timeline. That simplicity makes C4 Auto a solid first grow without sacrificing quality.
The cannabinoid profile sits between 16 and 24% THC alongside a meaningful CBD presence of 1 to 5%, which gives the experience both body weight and mental clarity. Effects lean toward relaxing and grounded while retaining enough sativa character to keep the mind engaged rather than fogged. It's a balanced hybrid in the truest sense.
C4 Auto completes its full cycle in 8 to 10 weeks from germination, which is typical for a well-bred Fast Buds autoflower. That relatively short window means you can run multiple harvests in a single season outdoors, or keep an efficient rotation going indoors without long waits.
The flavour profile is earthy and sweet — a grounded, natural combination that's approachable without being plain. The aroma follows the same character, making it pleasant to grow in most environments without being overpowering.
