Thunder Banana© Autoflower genetics: Thunder Banana x Sour Diesel Auto

Thunder Banana© FeminizedXSour Diesel Autoflower→ Thunder Banana© Autoflower

Thunder Banana© Autoflower, part of the Seedstockers Superior collection, was born from crossing Thunder Banana© Feminized with Sour Diesel Autoflower. She was created to maximise sweet, tropical flavour, potency and yield in an easy-to-grow auto.

From Thunder Banana© Feminized she inherits a very rich lineage: Alaskan Thunder Fuck (aka Matanuska), a hardy, tough genetic from Alaska's Matanuska Valley, and Amherst Banana (Amherst Sour Diesel x Banana OG), which brings a pungent fuel aroma and the best of OG Kush. Sour Diesel Autoflower provides the autoflowering trait and boosts the citrus and diesel notes. Thunder Banana genetics are also behind Thunder Dawg® Regular.

Thunder Banana© Autoflower aroma and flavour: banana, pineapple and tropical sweetness

CandyHerbalBananaPineappleCitrus

FLAVOUR

Rich, exotic and sweet, somewhere between pineapple and banana, it clings to your palate. It's an unusual sweetness, with a herbal backdrop and the depth of OG Kush that comes through Banana OG.

AROMA

Fresh, powerful and enticing, full of sweet tropical fruit. Early in bloom citrus takes the lead, mid-bloom sweet pineapple dominates, and by the end it turns into a cocktail of juicy fruit where banana really strengthens over the last week or two. Sour Diesel adds spicy, fuel-like touches.

Thunder Banana© Autoflower effects and THC

With 20 to 26% THC, Thunder Banana© Autoflower is one of our high THC seeds and a heavy hitter that serious smokers will appreciate. She starts with a floaty, joyful and euphoric cerebral feeling, perfect for a relaxed walk in the park, although perhaps too strong if you need to focus on work afterwards. Little by little that lightness melts into a body effect that relaxes mind and body and is ideal for an afternoon nap. If you want to get the most out of her potency and terpenes, let each plant finish blooming in her own time.

How to grow Thunder Banana© Autoflower seeds indoors and outdoors

Thunder Banana© Autoflower has been selected for her ease of growth. Although she's sativa-dominant, you'll see a slight phenotype spread: some more indica-leaning, with tighter, more compact flowers, and others more sativa-leaning, with slightly less dense buds that still feel firm inside, which stretch a bit more and may need an extra week or two. Plants average around 50 cm by harvest: between weeks 4 and 6 they double or triple in size in a manageable stretch that leaves just enough internodal spacing for the blooms to stack nicely.

For indoor growing, she's a compact, bushy plant that won't take up much vertical space, ideal for multi-level grows. Numerous plants in 5-10 L pots work great. She responds well to topping and LST, although many growers get the best yields from lollipopping: removing most of the lower branches so the plant puts her energy into the main central bloom. Use screens or supports, as her branches may not be strong enough to hold the weight of the buds.

For outdoor growing, she can be sensitive to powdery mildew in damp, cold, late-season climates, so pick the warmest, sunniest and driest three months. In dry, Mediterranean-type climates you can get two or even three successive crops a year. During testing, every plant yielded over 100 g with premium potency, which puts her among our high-yielding strains.

One of her phenotypes, the shorter and bushier one, produces incredible amounts of trichomes, ideal for ice-water extraction with an Ice-O-Lator and generous yields of hash. Her intense terpene profile delivers incredibly flavourful concentrates, whether you use CO2, ethanol, butane or other hydrocarbons.

Is Thunder Banana© Autoflower the right choice for you?

She's for you if...

  • ✅ You want an autoflower with a tropical banana and pineapple flavour.
  • ✅ You have little vertical space and want plants of about 50 cm.
  • ✅ You're after high THC with a joyful effect that ends in relaxation.
  • ✅ You make your own hash or extracts.

She's not for you if...

  • ❌ You grow outdoors in a cold, damp area late in the season.
  • ❌ You need an effect that lets you stay productive at work.
  • ❌ You want a strain that's mild in THC.
  • ❌ You want the fastest possible autoflower.

Convinced? You'll find her alongside the rest of our autoflower cannabis seeds, ready to grow in your tent, on your balcony or in your garden.

I love Banana strains and this one was very pleasant, my friend grew it so I don't know much about the growing but the taste was from another world, not super strong but very chill, I got an baggy of nugs and treat them like gold, sweet staiva, love it!

Thunder Banana Auto

Ran for 90 days under the sun. Dried for 10 days. 40g of keeper, 15g for oil. Excellent daytime medicine of surprisingly dense nuggets, glistening in trichomes. She got a rough start in cool weather which kept her on the smaller side. Will grow this one again!
