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.

      Overall, really impressed with the Grandaddy Banner! Most of the seeds germinated quick, but one was a bit stubborn and took longer. Not a big deal though, cause the final result was absolutely worth it. Fat, frosty buds with a punchy fruity aroma and a killer high. Also appreciated the good customer service when I asked about the slow starter. Thanks, guys!

      Grew two under 600w HPS. Medium stretch in flower, responded well to topping. Big yield. Buds dense and gassy. Smells got real loud week 7. Effects are powerful and long-lasting – not for beginners.

      Frost factory!! Grew this one under 300W LED and got tight nugs with deep purples and orange hairs. Smell is amazing — sweet diesel, kinda funky. Vaped some after a long shift and it just melted all the stress away. Also, really smooth on the lungs. Gonna keep this in my regular lineup.

      This strain really delivers. Grew her indoors under LED and she packed on weight like a beast. Dense, frosty nugs with that sweet berry-meets-gas aroma that fills the room. Effects are just chef’s kiss — heavy-hitting, creative, and super chill. Great after-work smoke to unwind but still keep a clear head. Top-tier genetics. Will absolutely run this again.

      The strain is straight 🔥, but I gotta be honest — one seed didn't germ, but Herbies hooked me up with a replacement fast, no stress. The plants that did grow came out chunky, colorful, and SMELLY in the best way. Smooth smoke, killer high. Worth it!

      Grew Grandaddy Banner as part of my “purple power” run this winter. This one stood out from the pack. From the moment it hit flowering, the smell started creeping — fruity with deep sour gas undertones. By week 6 of flower it was like walking into a candy-diesel fog. Buds turned a dark lavender with thick crystal frosting. I smoked a tester a bit early and still got couch-locked. After cure? Just wow. Powerful, relaxing, but mentally uplifting. Great nightcap strain.

      Dreamy smoke. The buds came out so colorful and caked in trichomes that I almost didn't want to grind them. Hits hard, but in a good way. Euphoric, relaxed, and a bit floaty. Love the mix of fruity and earthy flavors — super smooth on the inhale. Would recommend this to anyone chasing 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 😵‍💫

      Bro... this one’s a straight knockout 😂 Big nugs, fat trichomes, smells like sweet grapes with diesel undertones. Grew strong the whole way, no fuss. One joint had me glued to the couch with a smile on my face. If you like heavy hitters, don’t sleep on this beast🔥

      Grandaddy Banner is pure magic! 🌿 The plants grew super strong and healthy, with thick buds that were sticky and glittery with trichomes. The smoke is smooth, with a delicious berry flavor and a bit of sweetness at the end. The high is a perfect balance – relaxing yet uplifting, ideal for chilling in the evening without getting couch-locked. Definitely one of the best strains I’ve grown this year! Will 100% reorder

      Everything went smoothly without issues. Just normal conditions and minimal care, aside from watering and moderate fertilization. I pruned the leaves, and the buds started to swell. It's extremely potent, affecting both body and soul. It simultaneously induces euphoria and relaxation. The experience is rich with impressions and sensations over the three hours it lasts. Wears off gently, without a hangover, except for an increased appetite.

      This was my first time running Grandaddy Banner and I’m impressed. Easy to grow, took well to LST, and stayed pretty compact. The smell is wild — sweet and funky at the same time. Cured up nicely and the high is mellow but uplifting. Solid genetics.

      Yo this strain BANGS. I ain't even joking. Grows like a champ, smells like a gas station inside a candy shop. Big dense colas, sticky as hell. Smoked it with the homies and they all passed out on my couch — not even mad. 10/10, would grow again for sure.

      This one feels like it was cooked up in a mad scientist's lab — pure magic. The smell hit somewhere between overripe grapes and jet fuel, and somehow that combo works. The high starts in the head, like a creative jolt, then slowly wraps you up in this warm, hazy blanket. Grew her indoors and she colored up beautifully in late flower — looked like she came out of a fairytale forest
      Absolute vibe!

      This strain is pure magic! Tastes like sweet berries mixed with a little diesel kick. Easy to grow even for a semi-newbie like me. Got crazy dense nugs, and trimming was actually fun cause of how sticky and pretty the buds were. Smoke hits like a dream, relaxing but keeps you smiling.

      Fast flower, heavy yield, and absolutely gorgeous bag appeal. This girl was easy to train and responded well to topping. The high is a perfect mix — body melt with a clear-headed cerebral buzz. It’s like your brain is floating while your body’s wrapped in a warm blanket. Definitely one of my top 3 strains now.

      Really solid strain overall — smells incredible and hits hard. Only reason I’m giving 4 stars instead of 5 is that one of the seeds didn’t germinate. But I reached out and Herbies sorted it out fast with a replacement. The ones that made it grew strong, frosty, and full of flavor. No regrets here!

      Man, Grandaddy Banner is straight-up gas! Grew her indoors under LEDs and she stacked crazy thick buds with mad purple hues. Smoked a fat joint and got that head high that slowly melts you into the couch. Top-tier chill smoke for real ones!

    • General impressions

      An incredibly cool strain. The idea of combining Bruce and Purple Granddaddy into one is interesting. Together, they create an effect that's simply mind-blowing. It's like being on a rollercoaster, going up and down as if in free fall. But despite that, you're stuck to the couch, with jelly-like legs that won't move. I grew it in 15-liter pots, did topping and stretching.The light was 600W and the temperature was between 23-28°C. Freshly dried buds are bitter and smelly, but after curing, they're a completely different story. Overall, it's pleasant in every aspect. I'm eager to try growing the remaining seed outdoors.

      Grandaddy Banner is a solid strain — only thing is that flowering took a bit longer than I expected (about a week more), but wow, it was worth the wait. Big yields, heavy smell. Smoke is smooth, mellow, and heavy. Ideal for chilling 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!

    • Advantages
      Seeds germinated in 4 days even without pre-soaking. Bushes didn't cause any trouble
    • Disadvantages
      The effect is rather weak, 20% THC max
    • General impressions

      Can recommend it for beginners, since the variety turned out to be really unfussy and not so potent, but still the effect is not bad. The risk of overdose is minimal

      I use cannabis for both chronic pain and anxiety, and Grandaddy Banner hits that sweet spot. Immediate mood lift, followed by a strong but clear body effect. Doesn’t knock me out but keeps me calm
      The strain was quick to flower and gave a heavy yield — very impressed. It’s become a staple in my rotation

      Grandaddy Banner is a work of art. The plant was gorgeous during bloom — vibrant colors and a thick crystal coat. The aroma is rich and complex, like grapes, diesel, and a hint of earth

      The high is equally layered: a euphoric lift, then a peaceful body buzz. It's like the best of both parents - Grape Ape calm meets Banner intensity. One of the most refined strains I’ve grown
