Description
Born from the cross of Granddaddy Purple and Big Bud Auto, Royal Queen Seeds has bottled a genuinely compelling lineage into this feminised autoflowering variety. The aroma leans into ripe, sweet fruit with a grounding piney backbone, and the effect carries the relaxing, heavy-handed character that GDP has long been known for among indica lovers.
For cultivation, this is an approachable autoflower that rewards growers at every experience level. Being feminised and autoflowering, it removes the guesswork around light schedules and sex identification, making it well suited to both indoor tents and outdoor grows where simplicity matters. The harvest window of 10 to 12 weeks from seed is compact enough to fit multiple runs into a calendar year indoors. Yields in the range of 450 to 600 grams per square metre place it firmly in high-yield territory, meaning a modest 1.2 by 1.2 metre tent can realistically return a substantial personal supply. If you are looking for a well-bred, productive autoflower with genuine genetic provenance, this one earns its place in the garden.

about this product
Granddaddy Purple Auto delivers legendary indica heritage with fruity, piney depth and generous harvests, ready for beginner growers who want results without the complexity.
Granddaddy Purple Auto is one of the more forgiving varieties you can start with. Being feminised and autoflowering means you won't need to manage light schedules or worry about identifying and removing male plants — the strain does much of the heavy lifting for you. Royal Queen Seeds has designed it specifically with low-maintenance cultivation in mind.
Indoors, you're looking at 450–600 grams per square metre, while outdoor plants can push 450–750 grams each under good conditions. For an autoflower, that sits firmly in the high-yield bracket, which makes the 5-seed pack particularly strong value if you're planning a serious run.
The aroma blends ripe, sweet fruit with a grounding piney note that becomes more pronounced as harvest approaches. The effect leans heavily into GDP's indica roots — expect a relaxing, body-focused high that tends toward the sedating end of the spectrum, making evening sessions the natural fit.
From germination to harvest takes just 10 to 12 weeks, which is quick even by autoflower standards. Plants reach a medium height, so they sit comfortably in most indoor tent setups without requiring aggressive training to keep things under control.
