Triple XL Auto packs heavyweight indica character into a fast, easy-growing autoflower. Expect a lively lift, deep body relaxation, and dense, resin-coated buds in just 8 to 10 weeks from seed. Its compact size and forgiving growth make it a rewarding choice for new and experienced growers alike.

Our breeders crossed Northern Lights #5, Big Bud, and Green Crack to create a vigorous hybrid with impressive yield potential. The result leans 60% indica and 40% sativa, pairing classic relaxing genetics with a brighter, more energetic edge.

Citrus hits first, followed by earthy depth, skunky richness, and a warm spicy finish. Green Crack brings a touch of tropical-mango sweetness, adding a lively twist to the bold, full-bodied profile. Expect hard, frosty buds with plenty of aromatic character.

With THC levels of 15% to 20%, Triple XL Auto delivers an energetic, euphoric mood lift alongside soothing physical relaxation. The effect feels balanced and versatile, offering a cheerful spark for creative hours and a calmer finish as the day winds down.

Myrcene lends earthy, musky depth, while caryophyllene and humulene add peppery spice and woody notes. Terpinolene brightens the profile with citrus and herbal freshness; pinene, linalool, and farnesene round it out. Its abundant resin also makes this cultivar a strong choice for concentrates.

These autoflowering seeds flower according to age, so there is no need to change the light schedule to trigger bloom. Triple XL Auto suits indoor and outdoor gardens and is beginner-friendly. Every Grassfarmer seed comes with our germination guarantee for added confidence from the start.

Give seedlings a quality, well-draining medium with perlite, peat, or coco coir. Keep feeding measured and consistent through each growth stage, and provide strong light from the beginning. An 18/6 or 20/4 indoor light schedule supports vigorous growth and helps this quick-cycle plant make the most of its time.

Plants reach around 3.28 feet, with a sturdy main stem and productive side branches. Choose a sunny outdoor spot or provide strong LED lighting indoors. Keep temperatures warm, provide good airflow, and manage humidity carefully as flowering progresses. Watch for pests and protect the plant’s healthy growth.

Harvest arrives in about 8 to 10 weeks from germination. Indoors, expect high yields of around 800 to 1,000 g/m². Outdoors, plants can produce approximately 80 to 100 g each, with full sunshine supporting their potential. Dense, resinous flowers bring a satisfying finish to the rapid run.
