Grandaddy Banner Strain Info

You probably wouldn’t guess this strain’s dominant Indica nature by the effects it produces, as they are balanced between the Indica and Sativa sides and thus cater to every taste and preference. The breeders take pride in this strain’s creation – an ultimate crowd-pleaser that offers a potent high, exquisite aroma and taste, ease of cultivation, and hybrid vigor.

Genetics

Cannabis aficionados will most probably divine the family tree of Granddaddy Banner from its name. You got it right: it’s a cross of the legendary classic Grandaddy Purple with one of the bestselling strains of the last decade, Bruce Banner Alpha.

Flowering Time

As a dominant Indica, Grandaddy Banner typically finishes in around 56-63 days of 12/12 – a short enough flowering time to attract gardeners valuing fast turnover above anything else.

Yields

Grandaddy Banner is extremely generous and will reward the diligent, caring, and experienced grower with 600 g/m² (2 oz/ft²) of closely trimmed dried and cured buds. Outdoor yields are equally impressive and can go as high as 500 g (1.1 lb) per plant.

Effects

Your journey to total bliss starts with face-melting euphoria and a soaring flight of imagination, and it ends in physical relaxation so profound that you’ll feel one with the universe and have nothing left to wish for.

Medical Properties

Medical marijuana has proven its many uses, and Grandaddy Banner is the epitome of the healing benefits of this plant. Thanks to its balanced effects on both mental and physical well-being, it can take care of any nervous condition while alleviating inflammation and pain.

THC and CBD Levels

The huge potency of Grandaddy Banner is due to its 27% THC – a level that the best-grown samples often achieve. That’s especially good news for the heaviest of users and long-time medical patients. The latter will also appreciate the presence of CBD, although its content stays within a modest 2%.

Smell and Taste

Grandaddy Banner’s terpene profile is a gourmet’s delight. The sweet scent of vanilla in the cured buds is something you don’t encounter in many strains, while the combined aroma of spice and grapes can be found in just a handful of Purple varieties, all of which hail back to Grandaddy Purple.

Grow Tips

Grandaddy Banner plants reveal their noble pedigree right from the start. They have a towering central stem with short internodes, grow to a height of 150 cm (5 feet), and as the harvest gets closer, display a whole array of pink and purple hues, making them one of the industry’s most beautiful cultivars. The fat, dense, and heavy colas don’t hurt these striking looks, either.

  • The plants are tolerant of stress and suitable for beginners.
  • To prevent mold, regularly remove older fan leaves.
  • Use organic nutrients to do justice to this strain’s aroma and taste.

      The buds of the Fire 🔥🔥🔥 strain are very dense and smell incredibly good, like berries and gasoline. The smoke is clean, the effects are powerful, but get you buzzing. I'll be getting more seeds soon!

      Overall, I was really impressed with Grandaddy Banner! Most of the seeds germinated quickly, but one was a bit of a slouch and took longer to germinate. That's okay, because the end result was definitely worth it. Big, frosty buds with a strong fruity aroma and a devastating high. I also appreciated the excellent customer service when I asked about the slow starter. Thanks everyone!

      I grew two HPS under 600W. Medium stretch in flowering, good response to topping. Big yield. Dense and gassy buds. The smell became very strong in week 7. The effects are strong and long-lasting; not recommended for beginners.

      An ice cream factory! I grew this one under a 300W LED and got tight nugs with deep purple hues and orange hairs. The smell is amazing: sweet diesel, a little funky. I vaped some after a long day and it melted all the stress away. Plus, it's really easy on the lungs. I'll keep this one in my regular collection.

      This strain really delivers. Grown indoors under LEDs, it packed on weight like a beast. Dense, frosty nugs with a sweet, berry, gassy aroma that fills the room. The effects are chef-worthy: powerful, creative, and super relaxing. A great after-work smoke to unwind while keeping your mind clear. Top-notch genetics. I'd definitely smoke it again.

      Yo, this strain is awesome 😤 I grew it without any issues, with thick, frosty, and noisy buds. It gives off a sweet vibe of sweet grape and gasoline. The high hits hard — couch mode activated 💀🔥 Perfect for chilling or a nighttime session. This is definitely a plant to keep.

      The strain is pure 🔥, but to be honest, one seed didn't germinate, but Herbies quickly found me a new seed, stress-free. The plants that did grow became plump, colorful, and fragrant, as if by magic. A smooth smoke, a devastating effect. Worth it!

      I grew Grandaddy Banner as part of my purple power session this winter. This one stood out. From the moment it flowered, its scent was immediately apparent: fruity with deep notes of sour gasoline. By week 6 of flowering, it was like walking into a diesel candy fog. The buds turned a deep lavender hue with a thick crystal glaze. I smoked a sample a little early and still found myself couch-locked. After curing? Wow! Powerful, relaxing, but also mentally invigorating. A great strain to end the day with.

      A dreamy smoke. The buds are so colorful and covered in trichomes that I almost didn't smoke them. The effect is powerful, yet positive. Euphoric, relaxing, and a little airy. I love the blend of fruity and earthy flavors; the hit is super smooth. I recommend this product to anyone looking for flavor and potency.

      Bro. I blinked and the couch ate me. This stuff is like if Granddaddy Purp and Hulk had a baby who majored in psychology and knew exactly how to shut your brain off in the best way possible. I couldn’t move my legs but I didn’t want to anyway. 5 stars and an extra cookie for the terp profile – grapey gas funk explosion 😵‍💫

      Man... this one is a killer 😂 Big nugs, big trichomes, sweet grape smell with hints of diesel. It grew hard the whole way through, no fuss. One joint had me glued to the couch with a smile. If you like big hits, don't sleep on this beast. 🔥

      Grandaddy Banner is a pure wonder! 🌿 The plants grew super vigorous and healthy, with thick, sticky buds glistening with trichomes. The smoke is smooth, with a delicious berry flavor and a hint of sweetness on the finish. The high is perfectly balanced: relaxing and uplifting, ideal for unwinding in the evening without getting stuck on the couch. Without a doubt one of the best strains I've grown this year! I will 100% recommend it.

      Everything went smoothly. Normal conditions and minimal care, aside from watering and moderate fertilization. I pruned the leaves, and the buds began to swell. It's extremely powerful, affecting both body and mind. It produces both euphoria and relaxation. The experience is rich in impressions and sensations for the three hours it lasts. The effect fades slowly, with no hangover sensation, except for an increased appetite.

      This was my first time growing Grandaddy Banner, and I'm impressed. Easy to grow, she held up well to LST and stayed quite compact. Her scent is wild, sweet, and funky all at once. Cured well, she delivers a smooth yet uplifting high. Solid genetics.

      Yep, this strain is awesome. I'm not even kidding. It grows like a pro, smells like a gas station in a candy store. Big, dense buds, sticky as hell. I smoked it with my buddies and they all passed out on my couch—not even angry. 10/10, I'd definitely use it again.

      This one looks like it was concocted in a mad scientist's lab—pure magic. Its scent oscillates between overripe grapes and kerosene, and the combination works beautifully. The euphoria starts in the head, like a creative jolt, then slowly envelops you in a gentle warmth. Grown indoors, it took on magnificent colors at the end of flowering—it looked like it had stepped straight out of a fairy-tale forest. An incredible atmosphere.

      This strain is simply magical! Its taste is reminiscent of sweet berries, mixed with a hint of diesel. Easy to grow, even for a semi-beginner like me. I got incredibly dense buds, and trimming was really fun, as the buds were so sticky and pretty. The effect is incredible, relaxing, and puts a smile on your face.

      Fast flowering, heavy yields and a flawless appearance. This plant was easy to train and responded well to topping. The effect is a perfect mix: a melting body and a cerebral clarity. It's like your brain is floating while your body is wrapped in a warm blanket. Definitely one of my top 3 strains at the moment.

      A really solid strain overall; it smells amazing and hits hard. The only reason I'm giving this 4 stars instead of 5 is that one seed didn't germinate. But I contacted them and Herbies quickly fixed the problem by replacing it. The ones that did sprouted vigorously, with beautiful freshness and intense flavor. No regrets!

      An incredibly cool strain. The idea of ​​combining Bruce and Purple Granddaddy is interesting. Together, they create a simply breathtaking effect. It feels like a roller coaster, with ups and downs like freefall. Despite this, you're glued to the couch, your legs like jelly. I grew it in 15-liter pots, topped and stretched. The light was 600W and the temperature between 23 and 28°C. The freshly dried buds are bitter and fragrant, but after curing, it's a completely different story. Overall, it's enjoyable in every way. I can't wait to try growing the remaining seeds outdoors.

      Grandaddy Banner is a solid strain. The only problem is that flowering took a little longer than expected (about an extra week), but wow, was it worth the wait. Large yields, intense aroma. The smoke is smooth, mellow, and powerful. Perfect for relaxing after a long day.

      Grandaddy Banner by AlphaFem Seeds is an impressive hybrid that showcases excellent breeding work. Seeds germinated quickly and uniformly, and the plants displayed strong, vigorous growth throughout veg. In flower, the aroma turned intensely sweet with berry and earthy undertones. Buds were exceptionally dense, frosted with trichomes, and developed gorgeous purples towards harvest. Smoke is smooth with a fruity inhale and a slightly gassy exhale. Effects are potent: a strong head rush followed by deep relaxation without complete sedation. A fantastic choice for growers looking for bag appeal, potency, and a balanced hybrid experience. Highly recommended!

      I wasn't sure I could handle a 'Banner' strain, but this one was surprisingly easy to grow. No nutrient or light sensitivity issues, and training was easy. Big, dense buds and incredible curb appeal. A great mix of cerebral high and body relaxation. I'll definitely grow this again next season. 👍

      I can recommend it to beginners, as the strain turned out to be really undemanding and not so potent, but the effect is not bad. The risk of overdose is minimal.

It doesn't knock me out, but it calms me down. The strain flowered quickly and produced a bountiful harvest; I'm impressed. It's become a staple in my selection.

      Grandaddy Banner is a work of art. The plant looked stunning during flowering: vibrant colors and a thick layer of crystals. The aroma is rich and complex, reminiscent of grape, diesel, and a hint of earth. The effect is equally complex: a euphoric rush, followed by a soothing body buzz. It's like the best of both parents: the calmness of Grape Ape meets the intensity of Banner. One of the most refined strains I've grown.
