Querkle by TGA Subcool Seeds
3 other breeders' versions of Querkle — compare flowering times side by side →
Back when Subcool was running TGA and revolutionizing the medical scene, Querkle was the absolute gold standard for grape terps. Bred around 2006, Subcool took the legendary, painfully slow-growing Purple Urkle and hit it with his insanely vigorous Space Queen male. The goal was simple: keep that iconic Urkle flavor and color but fix the vegetative speed and yield. He nailed it. Querkle became an instant cult classic. Since Subcool passed away in 2020, the original TGA stock is gone, but places like Overgrow are keeping the flame alive with massive preservation runs of F2 and F3 stock just to make sure this legendary line doesn't disappear.
In the garden, Querkle is an absolute dream for indoor growers running a SCROG setup. She stays short, squat, and bushy, usually finishing up in around 8 weeks. You're almost always going to find two distinct expressions in a pack. One is a short, stocky pheno that turns almost black-purple in late flower with ridiculous frost, leaning heavily into the Urkle side. The other stretches a bit more, showing off some of the Space Queen's sativa vigor while still putting on heavy weight. She isn't the heaviest feeder, but give her enough phosphorus in mid-flower and those colas swell up beautifully.
The nose on Querkle is what made her a legend. It's a deep, musty grape and berry aroma—like old wine mixed with fresh soil and a hint of sweet candy. Smoking it is like drinking grape soda that leaves a hashy film on your palate. At 80% indica, the effects do not play around. You get a quick flash of cerebral, creative energy that lasts maybe ten minutes before a heavy, warm blanket of sedation drops on you. It's renowned as medical-grade gear for chronic pain and insomnia. If you're smoking Querkle, you better make sure the fridge is stocked and your couch is comfortable, because you aren't going anywhere for the rest of the night.

Growing Querkle: what to expect
As a hybrid, expect a moderate stretch after the flip (around 100%) — but watch the plant, not the label: phenotypes within Querkle can lean either direction. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
Querkle FAQ
Is Querkle an indica or a sativa?
The breeder doesn't specify — treat it as a hybrid and read the plant.
