Granddaddy Purple Seeds: A Cannabis Legend
Granddaddy Purple is an extremely potent strain with vibrant purple hues and a delightful grape taste. Nicknamed GDP, it has a strong reputation for its ability to induce relaxation and euphoria unlike any other.
GDP’s lineage includes Purps and Ghani heritage, which makes this bud a must try for any enthusiast.
Granddaddy Purple is not new to the cannabis scene. This strain came out on top at the prestigious High Times Cannabis Cup in 2015 that was held in San Bernardino California.
Granddaddy Purple boasts a whopping 23% THC content. Its negligible CBD content makes it less suitable for anyone looking for a more balanced high. While beginners may find it overwhelming, experienced users will love the torque in its hits.
This strain is an Indica dominant hybrid that is 70% Indica and 30% Sativa. The hybrid ratio contributes greatly to its calming effects, as it is an excellent choice for unwinding in the evening or for nighttime relaxation. GDP is also a favorite of medical users looking to combat insomnia and stress. The slight sativa has a gentle influence that gives off a euphoric touch without being overly stimulating.

Flavor and Effects of Granddaddy Purple
GDP boosts a delightful flavor and aroma profile. It all starts with its potent terpene profile:
Myrcene contributes mild sweet fruitiness that is often associated with a calming body high.
Beta-Caryophyllene adds a spicy, peppery note and may offer potential therapeutic benefits.
Pinene imparts a piney aroma and enhances alertness and memory.
Granddaddy Purple aroma captivates your senses with an initial blend of sweet and ripe grapey notes. A deeper inhale unleashes earthy undertones to ground the sweetness with an inviting pungent muskiness. The strain saves a magical lavender hint for the last kick adding a delicate floral touch.

Growing For Optimal Growth
Granddaddy Purple offers impressive yields for your grow. Indoor cultivators can achieve up to 18 oz per square meter while outdoor cultivators see up to 20 oz per plant. This generous yield is also complemented by a high bud quality.
GDP is relatively easy to cultivate with our feminized marijuana seeds and is often a favorite among novices and the experienced cultivators. It shows significant resistance to common pest and mold attacks. This robust nature makes it simple to cultivate in various environments.
Here are some key conditions that will help you create an ideal environment for healthy Granddaddy Purple plants.
Germination
Seed germination is pretty straightforward. All you need is to provide moisture by putting your seeds in a damp towel kept in a warm enclosure away from any lighting. The seeds will successfully germinate in about 3 to 10 days resulting in healthy seedlings ready for transplanting.
Lighting
Granddaddy Purple requires consistent high quality lighting for optimal growth. For indoor setups, high intensity discharge (HID) lights or full spectrum LED draw lights are highly recommended. During the vegetative stage, expose your plants to 18 hours of light and 6 hours of darkness before transitioning to 12 hours of light and 12 hours of darkness in the flowering stage.
Temperature
The right temperature is crucial for growing Granddaddy Purple plants as it keeps your plans free from stress and shocks. With slightly cooler nights, daytime temperatures of between 70° F and 80° F (20°C to 27° C ) are recommended during the vegetative stage. During the flowering phase, the temperatures should always remain between 65° F to 75° F (18° C to 24° C) for optimal bud development.
Humidity
Maintain levels of between 40 to 70% during the seedling and vegetative stages to promote vigorous growth. You will then gradually reduce it to around 40-50% to protect the delicate buds from mold and mildew attacks.

Growing Granddaddy Purple Seeds Successfully
It is important to create an ideal environment for Granddaddy Purple to thrive. Here are key aspects to help you optimize the growing setup according to your setup and skill level.
Organic Soil
is the easiest to work with especially if you are new to growing Granddaddy Purple. As a natural and traditional medium, its complex mix of minerals, organic matter and microorganisms promotes good drainage and aeration. It also makes nutrients easily available and is more cost effective.
Coco Coir
is made from coconut husks. It is a sustainable and environmentally friendly option. Coco coir has an impressive drainage and aeration ability that helps alleviate overwatering. One key advantage for a coco coir setup is that it is reusable with proper sterilization after each growth.
Hydroponics
entails growing your Granddaddy Purple plants without using any soil. Instead you will be using nutrient rich solutions that may sometimes need experts to set up. Hydroponics give a more precise control over nutrient delivery and other environmental conditions. The optimized nutrient uptake leads to a more vigorous growth. This growth medium also uses significantly less water than soil based growing mediums.
Nutrients
Nutrients are vital building blocks for your Granddaddy Purple plants health. They directly influence their growth, yield and bud quality. With the right nutrients in each growth stage, your Granddaddy Purple plants develop strong flavorful buds.
Nitrogen-rich fertilizers are the primary driving force behind leafy green growth, as they support chlorophyll production essential for photosynthesis. Nitrogen deficiency leads to stunted growth and pale leaves.
Once the plants transition into flowering, focus shifts from leaf production to bud and flower development. Phosphorus plays a key role as it boosts root development for better nutrient uptake. Potassium on the other hand strengthens the plant structure and contributes to the formation of denser buds.
Pro Grow Tip : Always ensure good airflow to prevent fungus and mold. As well fresh air, results in higher carbon dioxide levels, which in turn boosts plant growth.
History and Lineage
Granddaddy Purple cannabis strain is a creation by Ken Estes. The legendary breeder aimed to combine the best traits of Purps and Ghani heritage. It is said the GDP strain is a three way cross between Mendo Purps, Skunk and Afghanistan. Some cannabis enthusiasts dispute this lineage, replacing it with Purple Urkle and Big Bud genetics. The strain was released in 2003 and has since become widely popular especially in California for its beautiful colors and a sweet grapey flavor with potent relaxation effects.
