Blue Cheese Auto is one of the most eye-catching autoflowers in the Royal Queen Seeds lineup. She stays small, grows fast, and often finishes with colas that take on a striking purple hue, all while delivering the famous cheesy funk that Blue Cheese fans love.
Royal Queen Seeds created her by combining Blueberry, Cheese, and a ruderalis strain. Blueberry contributes sweetness, Cheese brings its signature character and cheerful effect, and ruderalis supplies the speed and autoflowering trait. Her genetic split is 40% indica, 35% sativa, and 25% ruderalis, with THC levels of up to 16%.
From germination to harvest she needs just 70–80 days (10 to 11.5 weeks). Indoors she reaches 1 to 2 feet (30–60 cm) and yields 11 to 13 oz/m² (310–370 g/m²). Outdoors she grows 2 to 4 feet (60–120 cm) tall and produces 2 to 4 oz/plant (55–115 g/plant).
Flavor and Effects: Cheesy Funk, Clear Head
Blue Cheese Auto’s flavor profile is contrasting yet complementary. Pungent skunk and sharp cheese hit first, right at the moment of inhalation. As the smoke settles, softer notes of fruit, pepper, and earth start to show, rounding things off with a gentle sweetness.
When those flavors fade, a clear-headed, uplifting high takes over. With THC up to 16%, the effect is manageable and functional, making her a solid option for daytime use when you want a lift without losing your focus. It feels like a relaxed lunch break with a cheese plate and good music.
Growing Blue Cheese Auto: Small, Speedy, Productive
Blue Cheese Auto seeds produce robust, vigorous seedlings that grow quickly. Sow each seed directly into a pot of about 3 gallons (11 L) filled with quality soil amended with organic matter and perlite for drainage. No switch to 12/12 is needed; run 18/6 or 20/4 lighting from sprout to harvest to keep her compact and fast.
If stealth is the priority, start low-stress training around the third week to keep her at roughly 16 inches (40 cm) indoors or 2 feet (60 cm) outdoors. Left untrained, she reaches about 28 inches (70 cm) indoors or 3.6 feet (110 cm) outdoors. Plants begin flowering after 3 to 4 weeks of veg. Remove fan leaves that shade developing buds, protect outdoor plants from heavy rain, and flush during the final two weeks. Her short cycle makes multiple harvests per season easy in warm climates.
