Cannabis seeds C4 Auto from Fast Buds

C4 Auto — purple dynamite of flavour, colour and yield

C4 Auto is a truly explosive mixture of Purple line genetics mixed with powerful Canadian ruderalis. Multi-stage selection has turned it into a stable, super-yielding polyhybrid that combines a fast life cycle, signature purple colour and sweet berry flavour.

Male genetics have shortened the flowering time, while the feminised line has given the strain a pronounced aroma, rich flavour and decorative appeal.

The result is a strain to be proud of: simple, productive and impressively beautiful.

The buds are dense purple shells covered in resin

C4 Auto's inflorescences are compact, bright and very resinous.

Thick purple petals, sprinkled with sugar crystals, contrast with bright orange pistils, creating a truly ‘explosive’ visual effect. This is a case where the plant is pleasing to the eye even before the first drying.

The effect is a two-hour rush of warmth, euphoria and calm.

C4 Auto works quickly and gently: after just a few minutes, a wave of relaxation washes over the body, moods even out, and a feeling of lightness, well-being and pleasant inner peace emerges.

The strain provides a perfectly balanced effect that simultaneously relieves muscle tension and stimulates mental activity.

The taste is refreshing, lemony and berry-like, reminiscent of cold citrus sorbet on a summer afternoon.

The effect lasts up to 2 hours and is well suited for relieving stress, eliminating migraines, relaxing after work or resting before bed.

Mature plant — a purple giant in 8-9 weeks

C4 Auto goes all the way from seed to harvest in just 8-9 weeks, while remaining a fairly large autoflower:

height up to 100-120 cm,

dense indica structure,

rapid gain in colour and mass.

After the second week of flowering, the plant begins to actively form buds, and each subsequent week you will see the buds fill out, darken, compact and literally fill with resin.

In the final two weeks, C4 reveals itself fully: a powerful central cola, bright purple colouring and a yield potential of up to 650 g/m².

Tips for growers — an easy, undemanding, rewarding strain

C4 Auto is great for beginners and pros alike:

it's resistant to pests and mould;

it grows in any conditions — indoors, outdoors, greenhouse;

it adapts easily to LST and other gentle training methods;

does not require complex fertilisation schemes or super-precise climatic parameters.

All it needs is a little space, moderate care and a stable light cycle.

Aroma — berries, earth and sweet oil

C4 Auto has a rich and dense terpene profile:

earthy and berry base,

oily sweet notes,

soft aftertaste of forest fruits.

There is no sharpness in the aroma — it is warm, sweet, calm and very memorable.
