Auto GDP was developed by crossing the famed Granddaddy Purple indica strain with a fast growing and rugged ruderalis phenotype. This means that all the features you'd expect from GDP are present, with enormous deep purple buds, entrancing body stones and a distinctly sweet and spicy grape flavour along with the quick grow and auto flowering nature of the ruderalis. THC levels are slightly lower on average than that of the original GDP, though still quite high at 19-22%, with CBD levels practically non existent.


True to its Granddaddy Purps heritage, Auto GDP offers an immense indica style stone that will have both your body and mind relaxed in no time. The high is also more manageable than that of the original GDP thanks to its slightly lower average THC levels, making this a fantastic option for those who wish to experience the supreme body soothing highs and boost in spirits while lowering the potential for couch lock.


Auto GDP seeds are a great option for any grower, being especially forgiving for those new to the craft. With a combination of hardy indica and resilient ruderalis genetics, Auto GDP plants will handle a wide range of environmental conditions that other varieties would struggle in. Excellent for those short on space, with heights ranging from 60 to 100cm. Plus with a fast flowering time of 8-10 weeks you wont have to wait long to harvest the stunning purple buds. In addition the auto flowering nature of these plants means they don't require the usual intensive lighting schedules that non auto strains need to begin flowering.

Appearance & Aroma

Standing out against the sparse emerald green leaves, the vivid purple buds of Auto GDP plants are both dense and immense, covered in sugar like trichromes and peppered with bright orange and yellow pistils. As you draw closer the unmistakable smell of grapes and wild berries begins to envelop you, with hits of pepper and pine entering the mix to create an unforgettable aroma.

MSNL Editors Verdict

Offering all the best characteristics of Granddaddy Purps, with a faster auto flowering period and more compact size, Auto GDP is a real breakthrough and easy to recommend for all fans of purps, especially those short on space and time.

Tasting Notes

It just wouldn't be a GDP without the sensational candy like flavour and aroma of sweet grapes and berries and we're happy to report that they are here in abundance. The fruity sweetness that dominates the initial smell and taste on inhaling is joined by pops of spice and mint on the exhale creating a wonderful flavour that lingers on the tongue.
