Description
Bred by Royal Queen Seeds from a cross of Tropicanna Cookies and Lemon OG, Watermelon Auto leans indica-dominant with a fruity aroma that carries the sweet, citrus-tinged character of both parents. THC sits in the 16 to 24% range alongside a medium CBD presence of 1 to 5%, delivering a grounded, relaxing effect with enough complexity to hold the attention of experienced consumers and newcomers alike.
As an autoflowering feminised variety, Watermelon Auto moves from seed to harvest in just 8 to 10 weeks, making it one of the more efficient options in the Royal Queen Seeds catalogue. Medium plant height suits it well to tents and confined indoor spaces, where well-managed canopies can return 450 to 600 g/m², a strong result for an auto. Outdoor plants yield modestly at up to 200 g per plant, but that compact footprint and rapid turnaround make multiple runs per season entirely realistic. A straightforward, forgiving grow that rewards a little attention with a lot of fruit.

FAQ
All you need to know
about this product
Watermelon Auto combines the fruity depth of Tropicanna Cookies and Lemon OG in a fast, beginner-friendly package ready for growers who want quality results without the wait.
It's one of the more approachable options in the Royal Queen Seeds range, rated easy difficulty and built with beginners in mind. The autoflowering format means no light schedule management is needed, and the 8 to 10 week seed-to-harvest window keeps the commitment short while still delivering a rewarding result.
Watermelon Auto carries a fruity, sweet aroma with citrus undertones drawn from both Tropicanna Cookies and Lemon OG in its lineage. The flavour profile is clean and approachable, making it a pleasant smoke for those who prefer something bright and fruity over earthy or diesel-forward strains.
Indoor growers can expect up to 450 to 600 grams per square metre under good conditions, which sits firmly in the high-yield category for an autoflower. Individual plants stay at a medium height and produce a modest up to 200 grams per plant, making them well suited to tent grows where canopy management matters.
THC comes in at 16 to 24% alongside a medium CBD content of 1 to 5%, producing a relaxing, potent body effect that leans into its indica-dominant genetics. The combination of cannabinoids gives the high a grounded, settled quality that works well for unwinding without being overwhelmingly one-dimensional.
