Yumboldt brings Emerald Triangle heritage, award-winning history, and deep indica calm to one remarkable seed. Its sturdy growth, resin-heavy flowers, and bright citrus-sweet flavor make this classic a standout for growers seeking an easygoing plant and a soothing evening experience.
Developed in California, Yumboldt earned recognition with a High Times Cannabis Cup win in 2001. Its exact lineage remains a mystery, adding to its old-school appeal. This feminized variety carries a 70% indica, 30% sativa profile and may reflect OG Kush influence.
Crack open a cured bud and meet a lively blend of citrus, ripe fruit, and sweetness over a rich, earthy base. The smoke is smooth and soft, with bright notes balanced by a mellow, grounded finish.
With THC levels of 18% to 20%, Yumboldt delivers a cheerful lift that settles into lasting body relaxation. Expect a calm, contented mood and a soothing, potentially drowsy finish. Many users choose it for unwinding in the evening and for support with sleep, pain, or arthritis.
Myrcene leads the terpene profile with earthy, musky depth. Limonene brings a fresh citrus edge, while caryophyllene adds warm spice and linalool rounds out the aroma with floral softness. This relaxing profile suits quiet nights, restful downtime, and extract-making thanks to the strain’s generous resin production.
These feminized seeds produce female plants, so growers can focus their space and care on flower production. Germination is guaranteed, giving you a confident start. Yumboldt is beginner-friendly and adaptable indoors or outdoors, with a temperate climate and consistent airflow helping it thrive.
Seedlings establish well in quality, well-draining substrate such as coco, peat, or a perlite blend. Feed appropriately as plants move through seedling, vegetative, and flowering stages. Indoors, ScrOG training can help shape an even canopy and improve light access to lower flowers.
Yumboldt grows compact and robust, reaching around 4.92 ft (1.5 m), with a strong main stem and sturdy side branches. Keep temperatures near 70–80°F (21–27°C), manage humidity as flowering progresses, and inspect plants regularly for pests. Outdoors, warm summers, steady sunshine, and well-draining soil encourage healthy development.
After 8–10 weeks of flowering, dense, crystalline buds arrive with a sweet, earthy fragrance. Indoor growers can expect medium yields of about 350–450 g/m² (1.15–1.47 oz/ft²). Outdoor plants can produce around 400–600 g each (14.11–21.16 oz), with harvest typically falling in October.
