Ideal for evening use, meditation, or simply winding down after a long day, C4 provides soothing effects without overwhelming sedation.


Thanks to its stability and selective breeding, C4 stands out as one of the most dependable autoflowering strains in the Fast Buds lineup. It offers consistent performance, excellent resin production, and striking visual appeal, making it a great all-rounder for both connoisseurs and newcomers.


Plant Appearance:

C4 grows as a compact, bushy Indica with multiple bud sites. Each site develops thick, resin-rich flowers that wrap tightly around the nodes and stem, gradually turning deep purple as flowering progresses. The plant maintains good internodal spacing and forms a strong central cola surrounded by chunky side branches. Reaching around 100 cm in height, it’s a hardy and adaptable strain that performs well both indoors and outdoors—even in cooler northern climates.


Grow Tips:

C4 is an easy, forgiving plant—ideal for beginners and professionals alike. It adapts well to light training methods such as LST to maximise yield and light penetration. For a more relaxing Indica-heavy experience, allow the plant to flower slightly longer before harvest. C4 thrives under most conditions, making it a reliable choice for any setup. Its resilience and fast turnaround make it particularly suitable for growers looking for quick, colourful harvests with minimal fuss.


Flavour and Aromas:

C4 offers a complex and smooth flavour profile. Expect a dominant earthy-berry base softened by sweet, buttery undertones that make each puff creamy and pleasant. The smoke is velvety and mild on the throat, leaving a lingering sweetness that perfectly complements its purple appearance. The aroma is fruity yet grounded, with subtle notes of spice and soil that enhance its natural richness.


Effects:

The effects of C4 are balanced and mellow, offering both cerebral stimulation and physical relaxation. Users typically experience an initial light head rush that transitions into a warm, calming body buzz. It’s great for evening relaxation, light meditation, or simply unwinding without heavy sedation. The hybrid nature ensures mental clarity while gently easing tension—ideal for casual users or those looking to decompress after a long day.


Strain Summary:

C4 by Fast Buds is a compact, colourful, and flavour-rich autoflower that embodies balance and quality. With its quick flowering time, forgiving nature, and delightful berry-buttery flavour, it’s a pleasure to grow and consume. The stable purple genetics, reliable yields, and mellow high make C4 a timeless classic in the Fast Buds collection—perfect for growers seeking beauty, taste, and balanced effects in one easy-growing strain.
