Fire Kush Auto packs classic Kush character into a quick, easygoing grow. Expect compact, sturdy plants and dense, resin-coated flowers with coffee, earth, and unmistakable Kush flavor. Its 8–10% THC profile leans mellow, while the autoflowering life cycle brings harvest within 8–10 weeks from germination.

Our breeders created Fire Kush Auto from Alien Grenades, Star Fighter OG, and Ruderalis. Its heritage reaches into OG Kush, Hindu Kush, and Tahoe Kush genetics, shaping a predominantly Indica hybrid with a 70/30 Indica-to-Sativa balance. The result is a resilient, compact variety with deep Kush roots and automatic flowering.

The aroma opens with roasted coffee and rich earth, then settles into warm, woody Kush notes. Each bud develops a heavy coating of resinous trichomes, adding a crystalline finish and a smooth, rounded smoke. It’s a bold, grounded flavor profile made for fans of classic Kush strains.

Fire Kush Auto delivers a calm, relaxed mood with a gentle lift of happiness and focus. Its low THC content makes for a milder experience than many high-potency varieties. The soothing, body-centered character suits a quiet evening or a laid-back break.

Myrcene contributes earthy depth, while caryophyllene adds a peppery warmth and humulene brings a woody, hop-like edge. Together, these terpenes help define the strain’s coffee-and-Kush character. Its resin-rich flowers also make Fire Kush Auto an appealing option for growers interested in aromatic harvests and concentrate production.

These feminized autoflowering seeds flower automatically, without a change in light schedule. The full cycle takes about 8–10 weeks, and plants can perform indoors or outdoors. Fire Kush Auto is beginner-friendly, and every Grassfarmer order includes our germination guarantee.

Start seedlings in a light, well-draining medium such as quality soil or coco with added perlite. Give young plants steady light, gentle airflow, and appropriately measured nutrients as they develop. Indoors, an 18/6 or 20/4 light schedule supports vigorous growth. Avoid overwatering and keep conditions consistent.

Plants grow compact and bushy, typically reaching around 4.9 ft (1.5 m). Choose a warm, temperate setting with plenty of sunlight and temperatures around 70–85°F (21–29°C). Use well-draining soil, maintain good air circulation, and monitor humidity as flowering progresses. The sturdy structure makes this variety suitable for a range of grow spaces.

Harvest arrives in 8–10 weeks, with medium yields of around 400–450 g/m² indoors and 400–600 g per plant outdoors under favorable conditions. Outdoor growers can plant through the season when local conditions allow, while indoor growers can plan repeated cycles throughout the year. Expect firm, resinous buds carrying the strain’s signature earthy coffee aroma.
