Granddaddy Purple Auto is a beautiful cannabis strain known for its purple hues. These seeds have a delicious grape taste and aroma, and they give a giggly, euphoric high.
The original Granddaddy Purple (a.k.a. Grand Daddy Purple, Granddaddy Purps, or GDP) cannabis seeds were created by crossing Big Bud x Purple Urkle and come from the California Bay Area.
This beautiful purple-colored plant was initially developed by Ken Estes in 2003 to meet the growing demand for a strain that was effective at relieving pain but also produced an easy-to-grow, high-yielding crop that can withstand cooler temperatures.
Adding potent Ruderalis genes into the mix ensured her compact size and a harvest for which one doesn’t have to wait long. The autoflowering variety of this purple-hued strain arose from crossing those excellent genetics with potent Ruderalis genes.
Granddaddy Purple autoflower possesses all the best features of the legendary Granddaddy Purple strain: her incredible appearance, sky-high THC levels, potent indica effects, and distinctive taste sensations. Now, it's combined with the ease of growing and fast flowering abilities of Ruderalis!
Her generous yields and layers of fruity flavors have made her one of the most popular autoflowering cannabis strains. The combination of hardy indica and resilient ruderalis genetics makes Auto Granddaddy Purple cannabis plants well-suited for a wide range of environmental conditions.
Her relatively short stature and preference for humidity-controlled environments make this Indica perfect for indoor growth. She will also thrive outdoors in mild and cooler climates with low humidity.
For successful growth, the plant prefers a humidity level of around 50%. We advise keeping the grow room well-ventilated.
As the cultivation progresses, you’ll soon notice she’s a true Indica. This is reflected in her internode spacing and broad-leaved fingers, which absorb sunlight efficiently. Her light green buds are dense and compact and display an array of purple hues ranging from the deepest purple to mauve.
The buds are also covered under a thick layer of glistening white trichomes.
Furthermore, this variety is also known for its high resistance to mold. This makes our Auto GDP autoflower seeds the perfect choice for all growers who like to grow high-quality weed without fuss.
Auto Granddaddy Purple is a Ruderalis variety, which means it is not light-dependent. Therefore, it starts to flower automatically once the plant reaches a certain maturity level. All in all, it has an 8—to 9-week flowering cycle before it is ready to harvest.
This short flowering period allows the outdoor grower to realize multiple harvests per outdoor season. Just ensure you complete your last harvest before the first frost sets in.
These autoflowering marijuana seeds grow into a relatively short plant that reaches an average height of 60 to 100 cm indoors and outdoors. This convenient, manageable height suits her perfectly for those with limited space.
Despite the modest height, these compact plants still produce a very decent yield. You can harvest up to 300 grams per m² with indoor growing plants. Outdoors, the average yield will be about 60 to 80 grams per plant.
The numbers above are based on healthy growth under ideal conditions, but advanced growers should be able to achieve similar results. With the prodigious Indica stone, this autoflowering strain lives up to her Granddaddy Purple heritage. She has slightly lower THC levels than her feminized original.
This makes auto GDP seeds also an excellent option for those who want to enjoy the profoundly relaxing effects while reducing the likelihood of the dreaded couch lock.
This strain offers a profoundly soothing effect that calms the nerves and stops racing thoughts. In addition, users report a happy, mild buzz accompanied by subtle waves of euphoria.
The distinct sweet and fruity flavor inherited from her popular parent strains makes for an irresistible smooth taste. The sweet grape aroma, combined with blended berries, tropical spices, and an earthy finish, exactly matches the expectations of this purple weed.
The scent is similar but with earthy pine and tart, slightly sharp notes of citrus.
