FastBuds: the benchmark of speed and quality in the world of autoflowering plants

FastBuds is not just a seed bank, but a true laboratory of genetic excellence, where ideas turn into stable and powerful cannabis varieties. Founded in 2010, the company has managed to combine American passion for innovation with a European breeding approach, creating a collection of autoflowers that has become a standard for growers around the world.

History and philosophy of FastBuds

The FastBuds journey began with a group of California enthusiasts who moved to Europe to develop and adapt top-tier American genetics to the demands of the international market. Their goal was ambitious — to show that autoflowers can compete with photoperiod strains not only in speed, but also in flavor, aroma, and potency.

Today the company’s headquarters is in Barcelona — one of the centers of European cannabis culture. Here the FastBuds team conducts ongoing research, expands breeding lines, and implements innovations in the field of pheno-hunting. Every new brand release is the result of dozens of tests, selections, and cross-breeding of the best phenotypes.

Working with genetics and an innovative approach

The key feature of FastBuds is a systematic approach to creating premium-class automatic strains. The company does not merely reproduce popular profiles, it carefully adapts American legends like Gorilla Glue, Gelato, or Cookies to a rapid growth cycle. The result is plants that reach maturity in just 9–10 weeks while preserving a rich terpene bouquet, dense buds, and a high THC level.

FastBuds actively invests in its own laboratories, greenhouses, and R&D projects, constantly refreshing the collection and maintaining a consistently high quality standard. Selection of the best genetic lines takes place under controlled conditions, which guarantees predictability and repeatability for every grower.

Reputation and recognition

Over the years, FastBuds has received dozens of awards at international exhibitions and festivals — from Spannabis to the Highlife Cup. But the brand’s main award is growers’ trust: from beginners who value simplicity and stability, to professionals seeking strong effects and signature flavor accents.

FastBuds doesn’t stop: each season the company introduces new strains, experimenting with terpene profiles, visual aesthetics, and plant resilience. Thanks to this, the brand is deservedly considered one of the flagships of modern autoflower breeding.

Seed bank awards

The FastBuds team has accumulated an impressive track record: according to various sources, the brand has won more than 20 international awards and cups in categories such as “Best Seed Bank,” “Best Autoflowering Strain,” “High THC Content,” and others.

In particular, in recent years FastBuds has achieved the following:

• 2025: four titles at the Autoflower World Cup 2025 — including 1st place in “Best Sativa,” 1st place for the highest THC level, 2nd place for “Best New Strain,” as well as the title “Best Autoflower Seed Bank.”
• 2024: victory in the “Sativa Dominant Autoflower” category with the strain Apricot Auto at the same competition.
• 2023: 1st place with the strain Strawberry Gorilla Auto at the American Autoflower Cup (Los Angeles).
• 2022 and earlier: awards for “Best Autoflower Seed Bank,” “Best New Strain,” as well as prizes at regional cups in Chile and other countries.

These achievements reinforce FastBuds’ reputation as one of the leading brands in the autoflower niche: placing among the winners at major international competitions is not just marketing, but evidence of a serious breeding approach and consistent quality.

C4 Auto

The C4 Auto cannabis strain is a striking example of how FastBuds combines proven “classic” genetics with modern auto technologies. This automatic hybrid was created on the basis of such legendary strains as White Widow, Skunk, and Big Bud, with ruderalis added for automatic flowering.

Time from sowing to harvest is about 8–9 weeks. The plant is fairly compact (about 80–120 cm in height) and is suitable both for indoor setups and for open or semi-enclosed environments. It produces many buds with a dense structure and noticeable purple hues on leaves and flowers — an eye-catching “bar of purple dynamite.”

Aroma and flavor: earthy-berry notes with a soft buttery (buttery) undertone; the smoke is smooth and pleasant. Effect: a balance between a sativa lift and indica relaxation — first a slight “heady” stimulation, then gentle body relaxation. For the grower: an excellent choice for beginners (thanks to simple agronomy and automation) and for experienced growers due to visual appeal and stability.

Californian Snow Auto

The Californian Snow Auto marijuana strain is a vivid example of FastBuds’ ability to adapt genetics with a distinctive Californian pedigree to autoflower seeds. The hybrid combines an old “hot” phenotypic line from California with a reliable ruderalis-auto base, resulting in a plant with a sativa-dominant character and automatic flowering.

The time from sowing to harvest is about 9–10 weeks (or ~56–70 days) under standard conditions. Growth is relatively moderate for a sativa: plant height is usually 80–130 cm with proper cultivation, which makes the strain suitable for closed rooms as well as open or greenhouse environments. Yields are impressive: with good lighting and nutrition you can expect 400–550 g/m² indoors and up to 250 g per plant outdoors.

Aroma and flavor are refreshing and fruity: dominated by notes of green apple, lime, and sweet candy, with a slight tang. Effect: distinctly sativa — light euphoria, a boost for creativity or conversation, without excessive heaviness, making it suitable even for daytime use. For the grower: an excellent choice if you are looking for an auto option with a sativa character, good visual appeal (dense, “snowy” buds thickly covered with trichomes), and fairly predictable cultivation.

Note that due to its sativa genetics it may have a stronger tendency toward vertical growth — applying LST or other forms of height control is sensible if space is limited.

Frostbanger Auto

Frostbanger Auto cannabis seeds represent a premium-class auto strain with a distinctly indica-dominant character — about 60% indica and 40% sativa — featuring extreme resin production. From sowing to harvest is about 9 weeks under standard conditions. The plant remains compact — usually 70–120 cm — which makes it suitable for indoor setups or limited spaces.

Yields are solid: indoors up to 450–550 g/m², and outdoors up to 60–200 g per plant. Aroma and flavor: sweet and creamy fruity notes with a light spiciness; thick, velvety smoke. Effect: powerful body relaxation with a gentle mental unwind — an excellent choice for evening rest or relieving tension after a hard day.

For the grower: ideal for those who want maximum resin and dense bud structure but do not want a long cycle or excessive plant size. However, keep in mind: the strain is strongly aromatic — air filtration (carbon filter) or other odor control is essential for indoor cultivation.

Guava Auto

Guava Auto is a balanced hybrid with roughly 50% sativa and 50% indica genetics. The seed-to-harvest cycle is about 8–9 weeks. The plant can reach 70–120 cm in height, making it suitable for both indoor and open or semi-enclosed cultivation.

Yields are impressive: indoors up to 450–550 g/m², and outdoors up to ~60–200 g per plant. Aroma and flavor: sweet tropical guava notes, a fruity bouquet with light creamy and candy accents. Effect: bright mood, uplift, sociability, and gentle body relaxation — an excellent choice for daytime use.

For the grower: simple agronomy (high resistance to mold and pests) and suitable for both beginners and experienced growers, especially for those who want a tasty profile and a quick cycle without quality compromises.

Lemon Cherry Cookies Auto

Lemon Cherry Cookies Auto is a refined automatic hybrid with indica dominance — about 70% indica and 30% sativa — with an impressive genetic pool: created as (Purple Lemonade Auto × Cookies Auto) × Cherry Cola Auto. The sowing-to-harvest time is about 8 weeks (about 56 days). The plant remains relatively compact: indoors its height typically reaches 80–120 cm, which makes it suitable for home growing and small spaces. Yields can be substantial: up to 450–550 g/m² indoors and roughly 60–200 g per plant outdoors under favorable conditions.

Aroma and flavor — sweet cherry notes with a bright lemon accent and distinct “cookie” (cookie) tones: think “cherry jam with a drop of lemon juice,” accompanied by a light tang. Effect: first a lively, slightly sativa-leaning inspiration, then a smooth slide into body relaxation, creating a cozy state without excessive heaviness. Suitable for those who seek a balance of flavor, effect, and visual appeal.

For growers this is an excellent choice if you want an auto strain with a striking appearance (deep purple buds with a thick layer of trichomes) and a strong terpene profile. Light defoliation is recommended along with controlling the final flowering phase by lowering night temperatures to enhance purple hues.

Papaya Cookies Auto

Papaya Cookies Auto is a vivid representative of autoflowering strains, designed for those who want maximum terpene flavor, strong effect, and good yields with relatively simple agronomy. The hybrid has predominantly sativa heritage (about 60% sativa / 40% indica).

The sowing-to-harvest time is about 8–9 weeks under favorable conditions. Growth usually reaches about 70–120 cm (≈ 28–47 inches) indoors, making it suitable for room, greenhouse, or outdoor setups with height control.
Yield: one of the “strong” output options — up to ~450–550 g/m² indoors is stated.

Aroma and flavor: tropical papaya, a sweet fruity layer, and a background “cookie” aftertaste. The strain emphasizes this terpene profile. Effect: moderately stimulating, with a mental uplift and light body relaxation — a combined character: alertness plus comfort, without heaviness.

For the grower this is an excellent choice if you want a visually striking, fast auto form with high resin content — suitable for beginners thanks to resilience and simplicity, and for experienced growers due to flavor and yield potential. If space is limited, plan for vertical control (e.g., LST, SCROG) due to a tendency to stretch.

Pound Cake Auto

Pound Cake Auto is an autoflowering hybrid with sativa dominance (about 60% sativa / 40% indica) and impressive potential for growers aiming at high results. The sowing-to-harvest time is about 10 weeks. Plants can reach roughly 90–150 cm, making the strain suitable for indoor and semi-open/greenhouse conditions.

Yield is quoted at ~400–600 g/m² under good conditions. THC content up to ~28% indicates a powerful effect. Aroma and flavor have a dessert profile — notes of cream, berries, and hazelnut; sweetness with a light fruity-berry accent. Effect: a combination of lively uplift, social mood, and comfortable relaxation — great for interaction and good vibes.

For the grower this is an excellent choice if you want an auto form with a pronounced dessert profile, a decent yield, and a rather sativa character. Note that height can be above average for autos — plan space or control growth (LST, training).

Purple Haze Auto

Purple Haze Auto is an updated automatic version of the cult-classic Haze: a sativa-dominant hybrid adapted for autoflowering and modern growing. Sowing to harvest takes about 8 weeks (≈ 56 days) under optimal conditions. Growth is compact for a sativa auto — about 60–100 cm indoors.

Yield is stated at ~400–550 g/m² indoors, and outdoors up to ~50–150 g per plant. THC content up to ~23% (according to producers) in typical conditions. Aroma and flavor: bright notes of cherry and sour lemon with a light Haze undertone — the classic Haze profile with a new “purple” visual effect. The effect is powerful, stimulating, and creatively uplifting without excessive heaviness — great for a productive day, socializing, or inspiration.

For the grower — an excellent option if you’re looking for a sativa-leaning auto, visually striking (purple hues of the buds with cooler nights), and still fairly predictable in cultivation. If space is limited, it’s advisable to control growth — LST or gentle plant training may help, as even autos can produce dense, heavy colas.

Purple Lemonade Auto

Purple Lemonade Auto is one of the most striking FastBuds strains, created for those who value not only yield and flavor but also visual pleasure. This indica-leaning auto (about 70%) merged Californian lemon genetics with bright purple phenotypes to deliver a unique citrus-dessert profile and rich colors.

Sowing to harvest takes about 9–10 weeks; plants usually reach 80–130 cm, remaining compact and manageable even in limited spaces. Yields are impressive: up to 450–550 g/m² with quality lighting and optimal nutrition. Aroma and flavor present a saturated citrus bouquet dominated by lemon and sweet fruits, with a light tang and tropical freshness. This is one of the brand’s most “dessert-like” autos: sweetness, tartness, and the signature citrus in perfect balance.

The effect is relaxing and positive. Purple Lemonade Auto combines a light lift with pleasant bodily calm, making it an excellent choice for evening relaxation or unhurried socializing, while avoiding heaviness and keeping perception clear.

For the grower the strain is extremely grateful — undemanding in care, stable, and it colors beautifully even without special tricks; slightly lower night temperatures enhance the purple tones. Suitable for both beginners and collectors of rare autos thanks to a blend of beauty, flavor, and yield.

Rhino Ryder Auto

Rhino Ryder Auto is one of FastBuds’ first and most proven autoflowering strains, which has become a benchmark of stability and endurance. It is an indica-leaning hybrid (about 80%) with a light sativa accent, bred from the legendary Medicine Man (aka White Rhino) and FastBuds’ auto lines. The result is a powerful, reliable plant with a pronounced therapeutic effect and resistance to external stresses.

Sowing to harvest is about 9 weeks, making Rhino Ryder one of the fastest auto indicas. Plants usually reach 60–100 cm, forming dense, resinous inflorescences with a classic “indica” structure. Yields range from 350 to 600 g/m² indoors and up to 70–200 g per plant outdoors — a level worthy of longer photoperiod strains.

Aroma and flavor — an earthy-citrus profile with hints of spices and light sweetness. You can catch notes of herbs, lemon peel, and resin — a classic for fans of “therapeutic” autos. Effect — powerful, deep, and long-lasting. Rhino Ryder Auto is known for pronounced physical relaxation and a sense of inner calm. It is ideal for evening use, relieving stress, muscle tension, and sleep problems. THC level is about 20%, with moderate CBD, which enhances the strain’s medicinal potential.

For the grower — an excellent choice for those who value simplicity and reliability. The strain is tolerant of watering mistakes, temperature fluctuations, and nutrient deficiencies, which makes it an ideal starting point for beginners. Experienced growers will appreciate the stability of phenotypes and bud density — it consistently delivers a “heavy” harvest even in limited conditions.

Smoothie Auto

Smoothie Auto is an aromatic hybrid from FastBuds, created especially for lovers of fruity terpene profiles and a soft, harmonious effect. It’s a balanced auto (about 60% indica / 40% sativa), based on the famous Blueberry and Somango lines — a combination that gave it a signature dessert flavor and cultivation resilience.

Sowing to harvest is about 8–9 weeks, with plants reaching 60–120 cm in height and showing an even growth habit without excessive stretching. This auto hybrid is great for small grow boxes, greenhouses, or open ground. Yield is up to 400–550 g/m² with good lighting, and outdoors up to 150 g per plant.

Aroma and flavor — a true fruit smoothie: a mix of tropical mango, sweet blueberry, citrus, and light creamy nuances. The terpene profile is strongly expressed, especially with organic feeding — the smoke is soft, sweet, and refreshing, without irritation. Effect — balanced, relaxing, and positive: first a gentle sativa lift and a wave of good mood, then smooth body relaxation without heaviness. Suitable for evening rest and daytime unwinding — in moderate doses it doesn’t sedate, leaving a feeling of comfort and ease.

For the grower — Smoothie Auto is an ideal option for those who want stable yields without complex tweaks. The strain forgives small mistakes, adapts quickly, responds well to LST, and produces dense, resin-covered buds. It shows especially beautiful purple-pink tones with lower night temperatures, making it not only productive but visually attractive.

Sour Jealousy Auto

Sour Jealousy Auto is an autoflowering version of a powerful sativa-dominant genetics, created for those who value high strength, expressive aroma, and large yields.

Yield is quoted up to 500–600 g/m² indoors and up to ~300 g per plant outdoors. THC up to ~29% makes it one of the most powerful among autos. Aroma and flavor — a pronounced sour profile with lemon and diesel notes, complemented by earthy and floral undertones, plus a light hint of black truffle. Effect is bright, stimulating, and creatively uplifting — ideal for daytime use when you want energy and inspiration.

For the grower — a great choice if you seek a sativa-leaning auto with strong effect and good yields. Keep in mind: due to a tendency to grow tall, it’s best to control vertical space and provide adequate ventilation and odor filtration (the strain is very aromatic). With proper cultivation, it will deliver impressive results.
