Double D Regular Seeds by KC Brains Holland · Danky Doodle Genetics

Double D Regular Seeds by KC Brains Holland, also known as Danky Doodle, are your ticket to cultivating a legendary, high-yielding sativa-dominant hybrid that combines robust genetics with a surprisingly clear-headed, powerful effect.

Ever feel like growing a monster sativa is a gamble? You invest months, only to battle mould, pests, or a plant that stretches out of control, leaving you with a disappointing harvest of airy buds. That frustration is real, and it turns what should be a rewarding hobby into a stressful chore. But what if you could grow a sativa that's not only resistant and manageable but also pumps out colossal, crystal-coated buds? That's the promise of Double D.

Typical Myths About Growing High-Yield Sativas

• Myth: Big yields mean sacrificing potency and flavour. Reality: Double D proves you can have both, with THC levels reaching up to 20% and a complex spicy-sweet profile.
• Myth: Sativa-dominant plants are always finicky and difficult for beginners. Reality: Thanks to its Viking and Big Bud lineage, Double D is notably resistant to diseases and mould, making it more forgiving than many pure sativas.
• Myth: You need a massive outdoor space or a professional indoor setup to get worthwhile results. Reality: While it thrives outdoors, Double D can be managed indoors, reaching a manageable height of around 1.50 m (4.92 ft) and still producing impressive yields.
• Myth: A short flowering time for a sativa means lower quality. Reality: Its 9-12 week flowering period is relatively quick for its genetic profile, allowing you to enjoy its powerful, clear effects without an endless wait.

What Double D Really Does (And What It Doesn't)

Double D is engineered for performance and resilience. It delivers on its promise of giant, dense buds packed with resin, offering a potent cerebral high that is euphoric and uplifting without the heavy sedation or next-day fog. It brings the classic sativa experience—energizing, creative, and social—wrapped in a plant that's tougher than it looks.

However, it won't turn a complete novice into an expert overnight. While it's forgiving, it still benefits from basic care: good light, proper nutrition, and attention during its vigorous growth phase. It also won't stay a tiny, discreet plant; it wants to express its sativa heritage with some vertical stretch, especially when flipped to flower.

Advantages and Benefits When Grown Properly

• Monster Yields: Potential for up to 300 g (10.58 oz) per m² indoors and a staggering 1500 g (3.31 lb) per plant outdoors under optimal conditions.
• Built-in Resilience: Inherited resistance from its Viking parent makes it tough against common moulds and pests, giving you peace of mind.
• Potent, Clear High: Experience a powerful, narcotic effect that locks you to the couch while keeping your mind unusually clear and free of next-day burnout.
• Adaptable Growth: Thrives in soil, coco, or hydroponic setups, indoors or outdoors, giving you flexibility in your grow space.
• Rich Aromatic Profile: Enjoy a complex bouquet of spicy, earthy scents with subtle sweet undertones as the buds mature and resin production peaks.

Tips to Choose Well According to Your Expectations

Double D is a versatile choice, but your goals will determine how you approach it. If you're after maximum yield and have the space, let it run wild outdoors. For indoor growers focused on quality and control, techniques like SCROG (Screen of Green) are highly effective to manage its height and maximize light penetration to those lower bud sites.

• If you expect maximum discretion, top it early and use LST (Low Stress Training) to keep its profile bushy and wide rather than tall.
• If you expect the fastest harvest, provide optimal nutrients from the start and don't stunt its growth with early mistakes; a healthy veg means a faster, more productive flower.
• If you expect the most intense flavours, pay close attention to the drying and curing process after harvest. This is where the complex spicy-sweet notes truly develop.

How to Grow Double D Seeds: A Quick Guide

Quick Overview: Regular, sativa-dominant hybrid from KC Brains Holland. 9-12 week flowering cycle. Ideal for growers with some experience seeking massive yields and robust plants.

Safe Start & Seedling Stage:

• Germinate in a warm (22-25°C), humid environment using the paper towel method.
• Transplant carefully into a light, airy seedling mix once the taproot is 1-2 cm (0.39-0.79 in) long.
• For stronger, stress-resistant roots from day one, consider a root stimulator like ROOTBASTIC ATAMI.

Vegetative Growth:

• Provide 18 hours of light per day. It will show vigorous, tall growth with long internodes.
• Use larger pots (15-20 L / 3.96-5.28 gal) if growing indoors to support its size.
• This stage is perfect for training. Apply LST or prepare for a SCROG to control height and encourage multiple colas.

Flowering & Harvest:

• Switch to a 12/12 light cycle to induce flowering. Expect a significant stretch (pre-flowering).
• Maintain good airflow and lower humidity to 40-50% to protect the dense buds from mould.
• In the final weeks, a bloom booster like Big Bud Advanced Nutrients can help maximize bud density and resin production.
• Harvest when most trichomes are milky with some amber for a balanced effect. Flush with plain water for 7-10 days before cutting.

Frequently Asked Questions

Is Double D suitable for beginner growers?

While not the absolute easiest, its disease resistance and adaptability make it a good choice for growers who have mastered the basics of watering and lighting. Its vigour forgives minor mistakes.

How tall does Double D get indoors?

Indoors, with a standard vegetative period, it typically reaches around 1.50-1.70 m (4.92-5.58 ft). Using training techniques like LST or SCROG can significantly reduce its final height.

What's the main difference between Double D and other KC Brains sativas?

Double D stands out for its specific cross (Viking '90 x Big Bud '93) which gives it a unique combination of sativa effect, indica-like bud structure, and the legendary yield potential of Big Bud.

When is the outdoor harvest time for Double D?

In the Northern Hemisphere, expect harvest around the end of September. It finishes flowering in 9-12 weeks after the natural light cycle triggers it.

Personal Experience of Pevgrow’s CEO (Alan)

I've heard all the myths about high-yield sativas being fussy and prone to mould, so I was genuinely curious about Double D. Let me tell you, this strain laughs in the face of those stereotypes. I've run it both in a tent and on a sunny terrace. Indoors, it does have that classic sativa stretch when you flip to 12/12, so I highly recommend using a SCROG net—it turns that vertical energy into a wide, even canopy of buds. Outdoors, it's an absolute beast; just give it space and good soil, and it rewards you with branches that sag under the weight of the colas.

The high is exactly as described: powerfully euphoric and uplifting, but without the racing anxiety some sativas can bring. It's a fantastic social smoke or for creative projects. The flavour is old-school—spicy, earthy, and complex—which I personally love. It's not the most pungent strain during grow, but a carbon filter is still a wise investment for discretion. For any grower tired of weak yields or finicky plants, Double D is a breath of fresh, potent air.
