Royal Queen Seeds – Watermelon Auto Feminized Seeds (Tropical Indica Autoflower) - 3 Seeds

Watermelon Auto is a tropical, dessert-like indica auto that delivers big flavour, relaxing effects, and strong yields in a compact, easy-to-manage plant. Bred from Watermelon x OG Kush Auto, this 75% indica / 20% sativa / 5% ruderalis hybrid is all about juicy terps and a deeply calming high.

 

Designed for flavour lovers, Watermelon Auto is loaded with fruity terpenes driven by limonene, myrcene, and other sweet, earthy compounds. Her resinous buds pump out bold watermelon and mixed tropical fruit notes, rounded with a subtle earthy base. Whether you’re rolling flower or filling a vape, she tastes like a chilled, fruity summer drink.

 

With around 20% THC and medium CBD, the Watermelon Auto strain delivers a comforting, body-heavy indica high that relaxes muscles, unwinds the mind, and helps smooth out stress at the end of the day. The CBD content helps soften any edge from the THC, making the experience soothing rather than overwhelming—ideal for evening sessions, movie nights, or winding down before bed.

 

In the grow room, Watermelon Auto seeds are both discreet and productive. Indoors, plants reach about 3–4 ft and can be left to grow a big central cola or shaped with low-stress training (LST) for a wider, more even canopy. Expect up to 16–19 oz/m² in as little as 8–9 weeks from sprout, with 6–7 weeks of flowering.

 

Outdoors, plants usually reach 3–4 ft and perform well in containers, raised beds, or directly in the ground, finishing around 8–9 weeks after sprouting and producing 2–3 oz per plant in good conditions. Her compact size and fast cycle make her an excellent choice for balconies, patios, small tents, and stealthy garden spots.

 

If you want a fast, tropical-tasting indica auto that hits hard, chills you out, and fits in almost any space, Watermelon Auto is an easy strain to fall in love with.
