Comparison Table of All 10 Strains

1. Northern Lights – Queen of Indica

Genetics and Origin

Northern Lights ranks among the most famous strains in cannabis history. It originated in the 1980s on the northwestern coast of the USA – likely in Washington state – by crossing Afghan and Thai landrace strains. Neville Schoenmakers brought it to Europe, where Sensi Seeds seed bank further perfected it and made it famous on the international scene.

Northern Lights became the genetic foundation for dozens of legendary hybrids, including Super Silver Haze and Shiva Skunk. Its stability and consistent performance made it the reference strain by which other indica varieties are still measured today.

Key Parameters

• Type: Pure indica (approximately 95 % indica / 5 % sativa)
• THC: 16–21 %
• CBD: < 1 %
• Flowering Time: 45–50 days (7–8 weeks)
• Indoor Height: 100–160 cm
• Outdoor Height: 200–300 cm
• Indoor Yield: 500–550 g/m²
• Outdoor Yield: 575–625 g/plant
• Main Terpenes: Myrcene, pinene, beta-caryophyllene

Effects and Flavor

Northern Lights offers a classic indica experience – deep body relaxation, a wave of euphoria, and gradual sedation leading to peaceful sleep. The flavor profile is earthy and sweet with prominent pine and subtly spiced notes. The aroma is intensely resinous with a sweet undertone.

Growing Tips

Northern Lights is the ideal entry strain for beginning growers. Plants are compact, undemanding of space, and show exceptional resistance to mold, pests, and growing errors – tolerating temporary overfeeding and mild temperature fluctuations without significant impact on yield. Short flowering time and compact habit make it particularly suited for indoor growing. An autoflowering version is also available, completing the entire cycle from seed to harvest in just 9–10 weeks.

2. OG Kush – California Legend

Genetics and Origin

OG Kush is one of the most influential strains of the modern era. It originated in early 1990s California, likely from a cross of Hindu Kush, Lemon Thai, and Chemdawg. The abbreviation "OG" still sparks debate – most commonly explained as either "Ocean Grown" (referring to coastal origins) or "Original Gangster" as a nod to its pioneering strain status.

OG Kush became the parent strain for hundreds of modern hybrids, including Girl Scout Cookies, Headband, and Bubba Kush. Without it, today's cannabis market would look fundamentally different.

Key Parameters

• Type: Indica-dominant hybrid (75 % indica / 25 % sativa)
• THC: 22–26 %
• CBD: < 0.3 %
• Flowering Time: 8–9 weeks
• Indoor Height: 90–130 cm
• Indoor Yield: 400–500 g/m²
• Outdoor Yield: 500–600 g/plant
• Main Terpenes: Myrcene, limonene, beta-caryophyllene

Effects and Flavor

OG Kush offers a strong, balanced effect – combining prominent cerebral euphoria with deep body relaxation. Effects onset quickly and last long. The flavor profile is complex: earthy base complemented by distinct citrus and pine notes with a characteristic diesel undertone. This very combination of flavors and strong effects ranks it among the most iconic strains ever.

Growing Tips

OG Kush requires a stable environment – consistent temperature of 20–26 °C, relative humidity of 40–50 % during flowering, and quality ventilation. Plants produce extremely dense flowers that are prone to botrytis mold without adequate air circulation. Regular defoliation is recommended, along with support for heavily laden branches in late flowering. Growing difficulty is medium – suited for growers with at least one completed grow.

3. Granddaddy Purple (GDP) – Purple Jewel

Genetics and Origin

Granddaddy Purple was created by Ken Estes in 2003 in San Francisco by deliberately crossing Purple Urkle and Big Bud. The goal was to combine the iconic purple coloring and fruity flavor of Purple Urkle with Big Bud's exceptional yields – and the result exceeded expectations. GDP quickly became one of the most sought-after indica strains on the entire West Coast and soon reached the international market.

Key Parameters

• Type: Indica-dominant (70 % indica / 30 % sativa)
• THC: 17–23 %
• CBD: < 0.1 %
• Flowering Time: 8–10 weeks (56–70 days)
• Indoor Height: 100–150 cm
• Indoor Yield: 450–500 g/m²
• Outdoor Yield: 500–600 g/plant
• Main Terpenes: Myrcene, pinene, beta-caryophyllene

Effects and Flavor

GDP combines strong body relaxation with pleasant cerebral euphoria. Effects are deeply sedating – growers describe them as a dreamlike state where thoughts flow freely in a pleasant haze while the body is completely relaxed. The flavor profile is distinctly fruity: dominant notes of grape, berries, and lavender with a subtle sweet undertone.

Growing Tips

GDP is a relatively undemanding strain that responds well to training techniques like LST and SCROG – the low, branching structure increases light exposure and resulting yields. To activate anthocyanins responsible for characteristic purple coloring, ensure nighttime temperatures of 10–15 °C in the final two weeks of flowering. GDP prefers warm and dry climate; dense flowers require regular monitoring for mold.

4. Hindu Kush – Pure Landrace

Genetics and Origin

Hindu Kush is one of the few pure landrace strains that survived into the modern era in relatively unchanged form. It comes directly from the mountainous region on the Pakistan-Afghanistan border, where cannabis has been cultivated for millennia – traditionally especially for hashish production by resin pressing. Hindu Kush genetics form the foundation of the entire "Kush" family of strains and are indispensable for modern breeding.

Key Parameters

• Type: Pure indica (100 %)
• THC: 18–24 %
• CBD: < 0.5 %
• Flowering Time: 7–8 weeks
• Indoor Height: 80–120 cm
• Indoor Yield: 350–400 g/m²
• Outdoor Yield: 400–500 g/plant
• Main Terpenes: Beta-caryophyllene, myrcene, humulene

Effects and Flavor

Hindu Kush offers a pure classic indica experience: deep body relaxation, mental sedation, and pronounced sedative effect. It's among the strains with the most intense "couch lock" effect – better suited for evening use. The flavor profile is earthy, woody, and mildly sweet with prominent sandalwood and anise notes. Resin production is surprisingly high for a landrace strain.

Growing Tips

Hindu Kush is an exceptionally robust strain – millennia of adaptation to harsh mountain environment ensure resistance to cold, drought, temperature fluctuations, and nutrient deficiency. It handles conditions where more sensitive hybrids would lose yield. Compact height of 80–120 cm makes it suitable for small growing spaces and demanding outdoor locations. For beginning growers, it represents a safe and rewarding choice.

5. Blueberry – Fruity Classic

Genetics and Origin

Blueberry was created by legendary breeder DJ Short in the late 1970s through complex crossing of Thai, Afghan, and Mexican landrace strains. It was a deliberate attempt to combine sativa cerebral effects with indica robustness and fruity flavor – with exceptional results. In 2000, Blueberry won first place at the Amsterdam Cannabis Cup in the best indica category, securing its place in cannabis breeding history. Since then, it has become one of the most copied strains worldwide.

Key Parameters

• Type: Indica-dominant (80 % indica / 20 % sativa)
• THC: 17–24 %
• CBD: < 1 %
• Flowering Time: 8–9 weeks
• Indoor Height: 100–150 cm
• Indoor Yield: 400–500 g/m²
• Outdoor Yield: 500–700 g/plant
• Main Terpenes: Myrcene, pinene, beta-caryophyllene, linalool

Effects and Flavor

Blueberry is named after its dominant flavor profile – intense blueberry sweetness complemented by vanilla notes and subtle earthy undertone. Effects begin with pleasant cerebral euphoria that gradually transitions to deep body relaxation. Unlike pure indica strains, Blueberry maintains an uplifted, content mood without heavy sedative effects – a true "happy indica" effect.

Growing Tips

Blueberry requires a somewhat more experienced approach than most indica strains on this list. Plants are sensitive to overfeeding, particularly with nitrogen in early vegetative stage – precise nutrient dosing pays off. To achieve maximum blueberry flavor expression and characteristic purple coloring, follow three rules: allow plants to fully mature and avoid early harvest, reduce nighttime temperatures to 12–15 °C in the final two weeks of flowering, and then perform slow drying with curing for at least 3–4 weeks.

6. Critical Mass – Yield Champion

Genetics and Origin

Critical Mass was created by Mr. Nice Seeds (Shantibaba) by crossing Afghani and Skunk #1. The name is no coincidence – it refers to the strain's tendency to produce massive, heavy flowers so substantial that branches literally break under their weight. This "critical mass" of flowers is both its greatest attraction and main growing challenge.

Key Parameters

• Type: Indica-dominant (80 % indica / 20 % sativa)
• THC: 19–22 %
• CBD: 1–5 % (CBD versions reach 5–8 % CBD)
• Flowering Time: 7–8 weeks
• Indoor Height: 80–140 cm
• Indoor Yield: 500–600 g/m²
• Outdoor Yield: 600–800 g/plant
• Main Terpenes: Myrcene, beta-caryophyllene, limonene

Effects and Flavor

Critical Mass offers pleasant, balanced relaxation – body looseness without excessive sedative effects, complemented by mild cerebral euphoria. The flavor profile is sweet with citrus and subtle earthy notes. Due to natural CBD content, it's one of the few strains on this list offering relevant therapeutic potential without specialized CBD breeding.

Growing Tips

Critical Mass is undemanding to grow but requires one specific intervention: branch support. Without bamboo stakes or SCROG netting, overloaded branches risk breaking at maturity. Dense flower structure also increases botrytis mold risk – key factors are ventilation and humidity under 50 % during flowering. With these precautions, it's one of the highest-yielding and least demanding indica strains on the market.

7. Purple Kush – Purebred Purple Indica

Genetics and Origin

Purple Kush was created in Oakland, California by deliberately crossing Hindu Kush and Purple Afghani. It's one of the few strains with documented 100% indica genetics without any sativa admixture. Purple Kush became the starting material for many modern purple hybrids and remains the reference against which other sedative indica varieties are measured.

Key Parameters

• Type: Pure indica (100 %)
• THC: 17–22 %
• CBD: < 0.5 %
• Flowering Time: 8 weeks
• Indoor Height: 60–100 cm
• Indoor Yield: 400–450 g/m²
• Outdoor Yield: 400–500 g/plant
• Main Terpenes: Myrcene, beta-caryophyllene, pinene

Effects and Flavor

Purple Kush offers intense body relaxation and strong sedative effect with slow onset and extended aftereffect – effects typically last 2–3 hours. It's among the most frequently recommended strains for sleep issues. The flavor profile combines fruity grape and berry tones with earthy and sandalwood undertones.

Growing Tips

Extremely compact habit (60–100 cm indoor) makes Purple Kush ideal for small grow operations, cabinet grows, and micro projects where space is critical. Plants are undemanding and tolerant of less-than-ideal conditions. To activate purple coloring, reduce nighttime temperatures to 10–15 °C in the final two weeks of flowering – the result is visually striking and has no negative impact on yield or potency.

8. Bubba Kush – American Classic

Genetics and Origin

Bubba Kush first appeared in 1996 in Los Angeles when Matt "Bubba" Berger crossed OG Kush with an unknown indica strain, likely Northern Lights. From Los Angeles, Bubba Kush spread throughout California and soon reached the global market as one of the most characteristic American indica strains.

Key Parameters

• Type: Indica-dominant (80 % indica / 20 % sativa)
• THC: 15–22 %
• CBD: < 1 %
• Flowering Time: 8–9 weeks
• Indoor Height: 80–130 cm
• Indoor Yield: 400–500 g/m²
• Outdoor Yield: 500–600 g/plant
• Main Terpenes: Beta-caryophyllene, myrcene, limonene

Effects and Flavor

Bubba Kush excels in strong physical effects – deep muscle relaxation, tension relief, and pleasant drowsiness. Cerebral effects remain mild: calm, content mind without excessive stimulation. The flavor profile is unique and easily memorable – chocolate, coffee, and hash with subtle sweet finish.

Growing Tips

Bubba Kush is medium-difficulty strain. Plants grow relatively slowly but produce extremely dense and resinous flowers. Regular defoliation of lower sections improves air circulation and ensures adequate light penetration. The strain responds best to organic substrates and live microorganism-based nutrition – live soil growing contributes to more pronounced terpene profile in the final product. With hydroponics, pay attention to pH stability, as Bubba Kush is more sensitive to its fluctuations than most indica hybrids.

9. Afghan (Afghani) – Progenitor of Indica

Genetics and Origin

Afghan (also Afghani) is one of the oldest and genetically most significant landrace strains in the world. It originates from mountainous regions of Afghanistan, where cannabis has been cultivated for thousands of years – primarily for traditional hashish production by resin pressing. Afghan genetics are contained in the foundations of countless modern strains, including Northern Lights, Skunk #1, and Blueberry, forming the backbone of all modern indica breeding.

Key Parameters

• Type: Pure indica (100 %)
• THC: 15–20 %
• CBD: < 1 %
• Flowering Time: 7–8 weeks
• Indoor Height: 80–120 cm
• Indoor Yield: 400–500 g/m²
• Outdoor Yield: 500–600 g/plant
• Main Terpenes: Myrcene, pinene, beta-caryophyllene

Effects and Flavor

Afghan offers deep body relaxation, mild euphoria, and gradual drowsiness – the classic indica effect in its purest form. The flavor profile is richly earthy and hashy with sweet spiced tones. Pronounced aroma is characteristically "old-school" – strong, penetrating, and resinous. Afghan is prized among concentrate makers for its extraordinarily high trichome production.

Growing Tips

Afghan ranks among the hardiest and easiest-to-grow strains ever. Millennia of selection in harsh mountain environments ensure robustness against cold, drought, stress, and nutrient deficiency. It's an excellent choice for beginning growers and outdoor cultivation in cooler climates – including Czech conditions. Compact growth and short flowering time make it usable even in smaller indoor spaces.

10. Gorilla Glue #4 (GG4) – Modern Powerhouse

Genetics and Origin

Gorilla Glue #4 – now officially renamed "Original Glue" – was created by chance through crossing Chem's Sister, Sour Dubb, and Chocolate Diesel by breeders Joesy Whales and Lone Watee. From a happy accident came a phenomenon: GG4 won first place at the Los Angeles Cannabis Cup 2014 and soon found its way into the offerings of growers and dispensaries worldwide. The name captures the resin's stickiness – scissors literally stick to your fingers during harvest.

Key Parameters

• Type: Indica-dominant hybrid (60 % indica / 40 % sativa)
• THC: 24–30 %
• CBD: < 0.1 %
• Flowering Time: 8–9 weeks
• Indoor Height: 120–180 cm
• Indoor Yield: 500–600 g/m²
• Outdoor Yield: 600–800 g/plant
• Main Terpenes: Beta-caryophyllene, myrcene, limonene, humulene

Effects and Flavor

GG4 ranks among the most potent strains on the market. Effects onset quickly and strongly – pronounced cerebral euphoria gradually transitions to intense body relaxation with pronounced "couch lock" effect. With THC exceeding 25 %, it's a strain for experienced users; inexperienced consumers may find the intensity uncomfortable. The flavor profile is complex: diesel base complemented by chocolate, coffee, and earthy spice notes.

Growing Tips

GG4 is medium-difficulty and requires a proactive approach in four areas:
- Height: Plants reach up to 180 cm indoors – without training (SCROG, LST, topping) they may outgrow space.
- Stickiness: Extreme resin production complicates trimming and handling – work with scissors cleaned in isopropyl alcohol.
- Flower Density: Compact, heavy colas require humidity under 50 % and powerful ventilation as mold prevention.
- Nutrition: GG4 is a heavy feeder – requires higher nutrient doses, especially phosphorus and potassium during flowering.

Proper care is rewarded with extreme yields of highly resinous material suitable even for concentrate extraction.
