Double Cookies

Double Cookies Feminised Cannabis Seeds by BSF Seeds

Double Cookies is a feminised indica-dominant cannabis strain from BSF Seeds that crosses Do-Si-Dos with an elite Cookies Forum clone — two heavyweight US genetics packed into one seed. With 24–27% THC and a flowering time of just 7–8 weeks, this is a compact, potent cultivar built for growers who value resin quality over sheer volume.

Double Cookies Genetics: Why This Cross Works

BSF Seeds built Double Cookies by pairing a Do-Si-Dos mother with an elite Cookies Forum father — both descendants of the original Girl Scout Cookies lineage. The result is an indica-dominant hybrid that stacks Cookies genetics on top of more Cookies genetics, which is exactly why the name fits. You're not getting a diluted cross here; you're getting a concentrated expression of everything that made the Cookies family famous in the first place.

Do-Si-Dos itself is a cross of Face Off OG and Girl Scout Cookies, so the Cookies influence runs deep on both sides of this family tree. BSF Seeds, a Spanish seed bank known for developing strains based on what they actually want to smoke, selected this particular combination from their Draft Line — their experimental breeding programme where the best phenotypes get promoted to the full catalogue.

The indica dominance shows in the plant's structure: compact, bushy growth with dense bud formation. If you've grown other Cookies-family strains, you'll recognise the tight internodal spacing and the way the calyxes swell during the final weeks of flower.

Growing Double Cookies: Yield, Flowering Time and What to Expect

Double Cookies finishes flowering in 7–8 weeks, which puts it on the faster end for an indica-dominant strain running 24–27% THC. That's a short window for the amount of resin this plant produces.

Let's be straight about the yields: 380–480 g/m² indoors and around 500 g/plant outdoors are not record-breaking numbers. If you're chasing maximum weight per square metre, there are strains that'll give you more. But Double Cookies compensates with bud density and resin coverage that makes trimming a sticky affair. The quality-to-quantity ratio tilts heavily toward quality here — every gram is packed with trichomes.

For indoor growers, the short flowering time means you can fit more cycles into a year. A 7-week phenotype under a 600W HPS or equivalent LED in an 80x80 tent could realistically push three harvests where a 10-week sativa would only manage two. That maths matters if you're working with limited space.

Flavour and Aroma Profile of Double Cookies

The Cookies lineage is famous for a reason, and Double Cookies delivers the full sensory package. Expect sweet, earthy tones as the base — that unmistakable biscuit-dough smell that gave the entire family its name. Underneath, there's a layer of fresh mint that cuts through the sweetness and stops it becoming cloying. The overall impression is somewhere between a bakery and an herb garden.

During the final two weeks of flowering, the terpene production ramps up noticeably. You'll want a carbon filter running by week five at the latest — this isn't a subtle plant once the buds start fattening. The cured flower holds its aroma well; properly jarred, the mint note actually becomes more pronounced after two to three weeks of curing.

If you've smoked the original Girl Scout Cookies or Do-Si-Dos, Double Cookies sits right between the two. It's got more of the minty edge from the Do-Si-Dos side than a straight GSC, but retains that classic cookie sweetness that makes the whole family so moreish.

Double Cookies Effects: 24–27% THC Indica Potency

At 24–27% THC, Double Cookies sits firmly in the high-potency bracket. The effect is deeply relaxing with a happy, contented quality — classic indica territory, but without the immediate couch-lock that some heavier strains deliver. There's an initial wave of mental calm before the physical relaxation settles in across the body.

According to a study on the effects of oral and vaporised cannabis (PubMed ID: 36147331), the diversity of cannabis products and their varying cannabinoid profiles can produce significantly different subjective experiences depending on the method of consumption. With a strain this potent, the delivery method matters. Vaporising at lower temperatures (around 180–190°C) tends to preserve more of the terpene profile, which may contribute to the overall experience through what researchers describe as the entourage effect.

A word of honest caution: 24–27% THC is not a starting point for anyone new to cannabis. According to general dosing guidance, even experienced users typically work with 10–15mg of THC as a standard dose for a notable effect. With flower testing at 27%, a single 0.1g bowl already contains roughly 27mg of THC before accounting for combustion losses. Respect the potency.

How to Grow Double Cookies Seeds

1. Germinate your Double Cookies seeds using the paper towel method or directly in a starter plug. Keep temperatures between 22–26°C and humidity around 70% until taproots emerge — typically within 24–72 hours.
2. Transplant seedlings into their first pot (0.5–1L) once the taproot is 1–2cm long. Use a light, airy growing medium. Double Cookies responds well to both soil and coco coir setups.
3. Maintain 18/6 light during vegetative growth. Given the indica-dominant structure, consider topping once above the fourth node to encourage lateral branching and an even canopy. LST (low-stress training) works well with this strain's naturally bushy shape.
4. Flip to 12/12 light when plants reach roughly half your target final height — Double Cookies will stretch moderately during the first two weeks of flower but won't double in size like a sativa would.
5. During weeks 3–5 of flowering, increase phosphorus and potassium in your feeding schedule. This is when bud sites stack and trichome production begins in earnest.
6. Watch for the mint-and-cookie aroma intensifying around week 5–6. Ensure adequate airflow and carbon filtration from this point.
7. Harvest at 7–8 weeks of flowering when trichomes show mostly milky-white with 10–20% amber under magnification. The indica genetics mean the harvest window is relatively forgiving — a few days either side won't ruin things.
8. Dry in a dark room at 18–20°C and 55–60% humidity for 7–10 days, then cure in sealed glass jars for a minimum of two weeks. The mint terpenes develop noticeably during the cure.

Double Cookies vs Other Cookies Strains

The Cookies family tree is enormous at this point, so here's how Double Cookies stacks up against two other popular options you might be considering.

Double Cookies essentially takes the best of both parents and finishes faster than either. The THC ceiling is higher than a standard GSC cut, and the flowering time is shorter than Do-Si-Dos. The trade-off is yield — you're giving up perhaps 20–50 g/m² compared to a Do-Si-Dos, but the potency and speed make up for it if quality is your priority. We'd pick Double Cookies over a standard GSC for the faster turnaround alone.
