Our take

Triple XL Autoflower brings together Northern Lights #5, Big Bud, and Green Crack crossed with Ruderalis — a lineage built for size and speed. At 20% THC and up to 600 g/m², it delivers balanced hybrid effects with berry, citrus, and earthy notes. Intermediate growers who want a fast-cycling plant with serious yield potential will feel right at home here.

Yields up to 600 g/m² indoors — unusually high output for a short autoflower
Full seed-to-harvest cycle completes in 56–70 days, no light schedule changes needed
Outdoor plants finish by late September to mid-October, ahead of most fall frost windows

Growing notes

Triple XL suits intermediate growers comfortable dialing in nutrients and environment. It stays short, which works well in tents or low-clearance outdoor spots. Indoors, the 56–70 day total cycle means you can run multiple harvests per year. Outdoors, plan for a late-September to mid-October finish. Dense, medium-sized buds reward growers who manage airflow carefully to prevent moisture buildup.
