Royal Queen Seeds – North Thunderfuck Auto Feminized Seeds (Powerful Hybrid Autoflower) - 3 Seeds
North Thunderfuck Auto takes the legendary Matanuska lineage and compresses it into a fast, hard-hitting autoflower that’s built for modern growers. Bred from North Thunderfuck x Ruderalis, this balanced hybrid (≈45% sativa / 50% indica / 5% ruderalis) delivers big potency, energetic yet relaxing effects, and very respectable yields in a compact, easy-to-manage format.
Despite the playful name, this strain is all business when it comes to effects. With around 21% THC, North Thunderfuck Auto puts most autos on notice. The high is fast-acting and uplifting, giving a sharp mental boost that’s perfect for mornings or daytime sessions when you want something to perk you up and keep you moving. Underneath that cerebral energy sits a smooth physical relaxation, keeping things comfortable without dragging you into full couch-lock.
Flavour-wise, North Thunderfuck Auto leans into a complex, classic profile: bright lime/citrus on top, backed by earthy, skunky, and piney notes. It’s punchy on the nose but smooth on the exhale, making it a solid choice for both flower and vaporiser use.
In the grow room or tent, North Thunderfuck Auto is a strong performer. Indoors, plants typically reach 3–4 ft, and can be kept shorter with low-stress training (LST) if you need extra stealth or vertical control. Expect yields around 18–19 oz/m², with 8–9 weeks of flowering and a full 10–12 week cycle from sprout to harvest.
Outdoors, in long-summer climates, plants usually finish at 4–5 ft and can turn out 3–5 oz per plant when given good sun and nutrition. The autoflowering nature means no light-cycle manipulation—just plant, feed, and let her run.
If you’re looking for a potent, energetic, and flavourful auto that behaves like a true premium hybrid, North Thunderfuck Auto deserves a spot in your next round.
