Banana Krumble Feminized Cannabis Seeds by Greenhouse Seeds
Banana Krumble is a 70% indica-dominant feminized cannabis seed strain from Greenhouse Seeds that pairs Banana Punch genetics with OG Kush for a deeply relaxing body stone and a flavour profile dripping with overripe banana and cinnamon. With 24–25% THC and a flowering time of just 56–63 days, she's built for growers who want heavy yields and serious resin production without waiting around all season.
Why Banana Krumble Seeds Deserve a Spot in Your Garden
Greenhouse Seeds have been crossing strains since the early days of the Amsterdam coffeeshop scene, and Banana Krumble is one of their more flavour-forward creations. The idea was straightforward: take Banana Punch — already famous for that unmistakable ripe banana nose — and cross her with OG Kush to add backbone, fuel, and a knockout body effect. The result is a strain that smells like a banana bread someone left in the oven five minutes too long, with a fuel kick on the exhale that reminds you there's OG in the mix.
What makes this one stand out from the dozens of banana-themed strains floating around? Resin. Banana Krumble produces an almost absurd amount of trichomes, making her one of the best banana strains for hash and concentrate production. If you run a press or make bubble hash, this plant will keep you busy. The buds come out dense, sticky, and absolutely caked — you'll want to wash your scissors halfway through trimming.
The one honest limitation: she's a hungry plant. Banana Krumble has moderate to high feeding requirements, and if you skimp on nutrients during bloom, you'll see it in the final weight. She's not the most forgiving strain for first-time growers who are still dialling in their feed schedules. If you're newer to growing, something like Greenhouse Seeds' Super Lemon Haze might be a gentler introduction — Banana Krumble rewards growers who already know their way around a pH meter.
Banana Krumble Grow Characteristics and Yield
Banana Krumble grows like a textbook indica during veg — short, bushy, with thick fan leaves that stack up quickly. She stays compact for most of her life, only starting to stretch in late vegetative growth. Final height lands between 170–200cm, so she's manageable in a tent but will fill out horizontally if you let her.

A few practical notes from what we've seen. Those dense, heavy buds can snap branches in late flower — support stakes or a trellis net aren't optional, they're a requirement if you want to make it to harvest without casualties. Plan for branch support from around week 5 of bloom onwards. The plant responds well to all growing methods and substrates, so whether you're in coco, soil, or running hydro, she'll adapt. Just keep the feed consistent and don't let her go hungry during the final push.
Outdoors, she wraps up in late September, which is workable for most of southern and central Europe. In cooler northern climates, you're cutting it close — a wet October could spell trouble for those dense buds. If you're growing outdoors in the UK or northern Netherlands, consider running her in a greenhouse or polytunnel to manage moisture and reduce the risk of bud rot in those tightly packed colas.
Banana Krumble Flavour and Aroma Profile
This is where Banana Krumble really earns her name. Crack open a cured jar and you get hit with an intense wave of overripe banana — not the artificial candy banana you find in some strains, but a deeper, almost fermented sweetness like bananas that have gone properly brown and are ready for the bread tin. Underneath that, there's a warm cinnamon spice note inherited from the Banana Punch side, and then OG Kush steps in with that signature diesel fuel undertone on the back end.
The smoke itself carries all of those notes through. On the inhale, it's sweet banana and baking spice. On the exhale, the OG fuel cuts through and leaves a slightly earthy, gassy finish on the palate. It's a genuinely complex flavour — the kind of smoke you actually want to sit with and pay attention to, rather than something that just tastes vaguely "fruity."
If you're processing the harvest into concentrates, that terpene profile translates beautifully into rosin and bubble hash. The banana and cinnamon notes concentrate and intensify, and you end up with extracts that taste almost dessert-like. We'd say Banana Krumble is one of the best strains in the Greenhouse Seeds catalogue specifically for extraction work.
Banana Krumble Effects: What to Expect
At 24–25% THC and a 70/30 indica-dominant split, Banana Krumble delivers a heavy, full-body stone that sets in quickly — a couple of puffs is typically all it takes. The effect is deeply physical and sedating, the kind that pins you to the sofa and makes even getting up for a glass of water feel like an expedition. This is an evening and nighttime strain through and through.
She's traditionally associated with unwinding after a long day — the sort of smoke you reach for when you want to switch off, put on a film, and let the day dissolve. The mental effect leans dreamy rather than cerebral; don't expect creative sparks or social energy here. This is pure relaxation territory.
One thing to watch: the potency is no joke. If you're used to strains in the 15–18% range, approach Banana Krumble with a bit of respect. The body stone can be overwhelming if you overdo it, and the sedation is strong enough that you won't want to have anything important left on your to-do list.
How to Grow Banana Krumble Seeds
- Germinate your Banana Krumble seeds using the paper towel method or directly in a starter plug. Maintain a temperature of around 22–25°C and keep the medium moist but not waterlogged.
- Transplant seedlings into their final containers once they've developed 2–3 sets of true leaves. Banana Krumble adapts to soil, coco, and hydro setups equally well.
- During vegetative growth, expect a compact, bushy plant with thick indica leaves. Light defoliation of lower growth improves airflow and light penetration to the canopy.
- Begin feeding at moderate levels early in veg and increase to high feeding during the transition to bloom. Banana Krumble is a hungry strain — calcium and magnesium supplementation is worth considering, especially in coco.
- Flip to 12/12 when the plant reaches roughly half your target final height. She'll stretch in late veg and early flower, reaching 170–200cm at maturity.
- Install support stakes or a SCROG net by week 4–5 of flowering. The dense, heavy buds will weigh down branches, and unsupported colas risk snapping.
- Harvest after 56–63 days of flowering (late September outdoors). Look for mostly cloudy trichomes with some amber for the full sedating effect.
- Dry in a dark, well-ventilated space at 18–20°C and 55–60% humidity for 10–14 days, then cure in glass jars for at least 2 weeks to let the banana and cinnamon terpenes fully develop.
Running Banana Krumble in a tent? Pair her with a complete grow kit that includes lighting, ventilation, and a carbon filter — those terpenes get loud in late flower, and your neighbours will know about it without proper filtration. If you're planning to press rosin or run bubble hash from the harvest, grab a set of bubble bags or a pollen press to make the most of her exceptional resin output.
Banana Krumble vs Other Banana Strains
The banana strain market has exploded in recent years, so how does Banana Krumble stack up? Compared to something like Barney's Farm Banana Punch, which leans more towards a balanced hybrid effect, Banana Krumble hits considerably harder on the indica side. The OG Kush parentage gives her a heavier, more sedating stone and adds that fuel complexity to the flavour that pure banana strains often lack.
| Trait | Banana Krumble (Greenhouse Seeds) | Banana Punch (typical) |
|---|---|---|
| Genetics | Banana Punch x OG Kush | Banana OG x Purple Punch |
| THC | 24–25% | 18–22% |
| Dominant Effect | Heavy body stone, sedating | Balanced, relaxing |
| Flavour | Overripe banana, cinnamon, fuel | Sweet banana, berry |
| Flowering Time | 56–63 days | 56–63 days |
| Resin Production | Very high | High |
| Best For | Evening use, extractions | All-day use |
If you want the banana flavour but need something you can smoke earlier in the day without being completely floored, Banana Punch is the lighter option. If you want maximum potency, maximum resin, and a stone that properly knocks you out — Banana Krumble is the one. We'd pick Banana Krumble specifically for extraction projects, where that extra resin production and complex terpene profile really pay off.
Frequently Asked Questions
Is Banana Krumble good for beginners?
She's manageable but not the easiest first grow. The moderate to high feeding requirements mean you need to stay on top of nutrients, and the heavy buds require physical support in late flower. If you've got one or two grows under your belt, you'll be fine. Complete beginners might want to start with a more forgiving strain first.
What is the best use for Banana Krumble buds?
Smoking or vaping in the evening is the obvious choice, but Banana Krumble's very high resin production makes her outstanding for hash and concentrate creation. Bubble hash, dry sift, and rosin all work brilliantly with this strain. The terpene profile concentrates beautifully.
Can I grow Banana Krumble outdoors in cooler climates?
It's possible — she finishes in late September, which is just about workable in northern Europe. The risk is moisture and bud rot in those dense colas if October rains arrive early. A greenhouse or polytunnel significantly reduces that risk. In southern Europe, she'll thrive outdoors without issue.
How much does Banana Krumble stretch during flowering?
She stays compact through most of veg, then stretches in late vegetative growth and early bloom. Final height reaches 170–200cm. Plan your flip accordingly — if you're in a tent with limited headroom, switch to 12/12 when she's around half your maximum available height.
How strong is the smell during growth?
Very strong. The banana and fuel terpenes become increasingly pungent from mid-flower onwards. A carbon filter is not optional if you're growing indoors and want to keep things discreet. Even outdoors, she's noticeable from several metres away during late bloom.
How much can I yield from Banana Krumble?
In good growing conditions with proper feeding, expect up to 500g per plant. Indoor yields depend heavily on light intensity and container size, but she's a generous producer when given what she needs. Skimping on nutrients is the fastest way to leave weight on the table.
Is Banana Krumble suitable for making hash?
Absolutely — it's one of her strongest selling points. The very high resin production and complex terpene profile make Banana Krumble an excellent candidate for bubble hash, dry sift, and rosin pressing. The banana and cinnamon flavours intensify beautifully in concentrate form.
