Banana Cookies

Banana Cookies Cannabis Seeds by Advanced Seeds

Banana Cookies is an indica-dominant feminised cannabis seed from Advanced Seeds that crosses Banana with Girl Scout Cookies to produce resinous, flavour-packed buds reaching up to 25% THC. With yields of up to 600g per plant outdoors and a 9-week flowering period, this strain rewards growers with dense harvests and a terpene profile that blends ripe banana, vanilla, nuts, and a surprising diesel edge.

Why Banana Cookies Seeds Deserve a Spot in Your Grow Room

Finding a strain that ticks every box — flavour, potency, yield, and ease of growing — is harder than it sounds. Plenty of dessert strains taste brilliant but produce wispy buds. Others pack weight but bore your palate. Banana Cookies genuinely does both, and that's down to its parent genetics. Banana brings the sweet, creamy terpene profile; Girl Scout Cookies delivers the resin production and structural density that turns small buds into sticky little rocks.

At 25% THC, the potency is firmly in the upper bracket. The effect leans heavily physical — a slow, soothing wave that starts in the shoulders and works its way down. There's a mood lift in there too, enough to keep the evening enjoyable rather than catatonic. We'd call it a solid after-dinner smoke, the kind you reach for when the day's done and you want to actually feel it leave your body.

The one thing to watch: those 80–100 cm indoor heights assume you flip to 12/12 at a reasonable size. Let Banana Cookies veg for too long under strong lights and she'll stretch more than the spec sheet suggests. If you're working in a shorter tent (120 cm or under), top early and consider a SCROG net to keep the canopy flat. Outdoors, she'll happily push past 2 metres and fill out like a small bush — give her space and she'll use every centimetre of it.

Growing Banana Cookies Seeds: Indoor and Outdoor

Banana Cookies is a vigorous grower that adapts well to both indoor and outdoor environments. Advanced Seeds bred this one for production, and it shows — 500 g/m² indoors and up to 600 g per plant outdoors are realistic numbers when you give the plant what it needs.

1. Germinate your Banana Cookies seeds using the paper towel method or directly in a starter plug. Keep temperatures between 22–26°C and expect taproots within 48–72 hours.
2. Transplant seedlings into their vegetative containers once the first true leaves appear. A light, well-aerated soil or coco-perlite mix works well — Banana Cookies responds to a medium that drains quickly.
3. Vegetate under 18/6 lighting. Indoor plants stay compact at 80–100 cm, so you can afford 4–5 weeks of veg in most setups. Top or FIM once above the 5th node to encourage lateral branching and an even canopy.
4. Flip to 12/12 to trigger flowering. Banana Cookies flowers for approximately 9 weeks. You'll notice dense bud sites forming quickly — support heavier branches with stakes or a trellis net from week 5 onwards.
5. Outdoor growers should plant out after the last frost and expect harvest in the first week of October. In northern European climates, keep an eye on humidity in late September — dense indica buds and autumn rain are not friends. Good airflow around the canopy is critical.
6. Harvest when trichomes shift from clear to milky with a few amber heads. Dry slowly at 18–20°C and 55–60% humidity for 10–14 days, then cure in jars for at least two weeks. The banana and vanilla terpenes really develop during a proper cure — rushing this step costs you half the flavour.

Terpene Profile and Flavour of Banana Cookies

This is where Banana Cookies earns its name. The dominant aromas are ripe banana and sweet vanilla — not artificial or candy-like, but genuinely fruity and creamy, closer to banana bread than banana sweets. Underneath that sweetness sits a nutty, almost biscuity layer from the Girl Scout Cookies side, and then a diesel undertone that cuts through on the exhale. It's an interesting blend: dessert up front, fuel in the back.

If you've grown or smoked strains like Gelato or Wedding Cake, you'll recognise that sweet-meets-fuel character. Banana Cookies leans sweeter than either of those, though. Compared to a pure Banana strain, the GSC genetics add depth and a slightly earthy, doughy complexity that stops the flavour from being one-dimensional. It's the kind of smoke where you actually notice the taste changing as the joint burns down — vanilla-heavy at the start, more diesel towards the roach.

We'd recommend a dry herb vaporiser set around 185–195°C if you really want to taste the terpene layers. Combustion still delivers the flavour, but lower-temperature vaping lets you pick apart the banana from the vanilla from the diesel in a way a lighter can't match.

Banana Cookies vs Other Dessert Strains

Banana Cookies outperforms standard Girl Scout Cookies on yield by a comfortable margin — up to 500 g/m² versus a more typical 300–400 g/m². It also brings a more distinctive terpene profile than either parent strain alone. If you want GSC structure and resin production with a fruitier, sweeter nose, Banana Cookies is the better pick. If you're after a shorter flowering time and don't care as much about flavour complexity, a straight Banana Kush finishes a week earlier.
