Bubble Kush Auto is the result of an ambitious Royal Queen Seeds project: capturing the character of legendary photoperiod strains in a quick, beginner-friendly autoflower. To do it, the team blended Bubble Gum, OG Kush, and Critical Automatic, then worked through several generations to settle the traits.
Her genetic makeup is 60% indica / 10% sativa / 30% ruderalis. That generous ruderalis share makes her tough, quick, and dependable, while the Kush and Bubble Gum heritage brings the flavor and the classic, mellow stone.
From germination to harvest, Bubble Kush Auto needs only 70–80 days, or about 10 to 11.5 weeks. Like all autos, she flowers on her own without a 12/12 light switch, so you can run 18/6 or 20/4 from start to finish.
Indoors, she tops out at 2 to 3 feet (60–90 cm), which is ideal for small tents and stealthy setups. Outdoors, she reaches 3 to 5 feet (90–150 cm), and her fast cycle makes it easy to plan multiple harvests in one season.
Flavor and Effects: Mellow Kush Comfort
The terpene profile is classic Kush with a twist. Earthy and peppery notes lead the way, backed by bright citrus, a little fruit, and a fresh pine finish. Every draw is full-bodied without being harsh.
At up to 16% THC, Bubble Kush Auto will not launch you into orbit. Instead, the high is steady, grounded, and relaxing. The head stays level, the body settles down, and the mood turns easygoing. Royal Queen Seeds lists the effect as sleepy and stoned, so she suits the evening.
She is a great match for smokers who prefer moderate potency and a comfortable, predictable experience over an intense ride.
Growing Bubble Kush Auto Seeds
Bubble Kush Auto delivers solid results in almost any environment. Indoors, expect 12 to 14 oz/m² (340–400 g/m²) from a tidy canopy. Gentle LST helps spread the branches and can lift yields, and her compact size also suits a sea of green with several small plants per square meter.
Outdoors, each plant can produce 4 to 6 oz (110–170 g) of compact, resinous flowers. She thrives in regions with long, warm summers, where staggered sowings can keep harvests coming from spring through late summer.
Start her in her final container, give her a light, airy medium, and keep the nutrients gentle. She rarely needs more than that to perform.
