Grand Daddy Purple (GDP) is one of the most famous and adorable purple strains according to both cannabis consumers and growers. This pure indica hybrid was bred by a California grower Ken Esters who mixed two popular indica strains: Purple Urkle and Big Bud. Thanks to this successful genetic crossing, we can benefit from the GDP's high potency and exquisite properties that feature heavy physical effects and a unique cerebral high.
Growing this strain is a double pleasure, as you can enjoy both its purple beauty and great qualities. Its abundant coloring is full of different shades, from orange to violet to nearly solid purple, which makes the strain extremely eye-catching. The GDP buds have a mild scent of pine, blueberry, and grape when broken, but naturally, they have a slight blossom scent. Depending on the growing conditions, this strain usually contains 19-27% of THC and 0.5-7% of CBD that provide you with muscle relaxation and head euphoria. You can use this strain to deal with pain, anxiety, insomnia, nausea, lack of appetite, and much more.
Grand Daddy Purple is a great choice for growing as it suits both indoor and outdoor cultivation. Thanks to its legendary genetics, the strain is a substantial producer that requires small space and low temperatures. As any indica, this hybrid has short bushy plants densely covered with sweetly scented buds. The flowering period begins in 60 to 70 days, after which you can harvest about 450-600g/m² of yield.
This indica is a great cannabis for cultivation in colder climates, as its signature purple hue appears after the plants are exposed to cold temperatures in the late stage of flowering. The best temperature range for the plants should be around 75-80°F at daytime and 50°F at night.
The best yield is usually harvested from outdoor plants grown under real sunlight from late April through the middle of October. The optimal growing conditions for this indica exist in the areas of Northern California, where the strain was initially bred, and in the high Sierra Nevada between 3,000 and 5,000 feet. Besides, GDP grows well indoors, either in soil, water, or air.
When cultivated indoors, the plants usually grow up to 3 feet; growing outdoors, the plants can reach up to 8 feet in height. Each plant has tight internodes and dark green leaves that later become purple. Large, heavy buds require your additional attention.
The plants are resistant to mold, but they may succumb to powdery mildew or bud mold if the air humidity is above the average level. Make sure your GDP plants have consistent airflow and try not to over-water them. Devote time to removing some fan leaves to allow more light to reach the internal nodes. The best time to water the plants is once in every 4-5 days paying attention to the soil. If the plants are still a little bit damp, it is better to wait till they become thirsty. To avoid other possible risks, plant your cannabis into 100% sterilized organic soil and nourish it only with organic nutrients.
The flowering period comes to its end when the plant’s buds and leaves turn from green to purple. The plants are usually ready for harvesting on week 10-11 when they have dense buds with large THC clusters. Examine the plant’s trichomes under magnification in order to catch the moment of peak harvest. After harvesting, the GDP's buds need to be slow dried and cured to provide the best taste, smoothness, and staying power.
Generally, the Grand Daddy Purple plants are forgiving and easily adaptable to any growing conditions. However, if you follow these tips, you will be definitely rewarded with a high yield of beautiful buds and get a fantastic high!
