How to Grow Northern Lights x Big Bud Auto
Northern Lights x Big Bud Auto is a heavily indica autoflower that joins two legendary producers into one quick, generous plant. It pairs a medium 18–22% THC with a notable 2% CBD, an earthy, piney, spicy-incense flavour and a powerful, deeply relaxing effect, on a compact, high-producing plant that finishes in 8–10 weeks.
Built from Northern Lights crossed with Big Bud and ruderalis, this is a 70% indica, 30% sativa autoflower that keeps the resin and relaxation of its parents while adding autoflowering speed and stability. Both Northern Lights and Big Bud are famous for their output, and this cross carries that productive streak, drawing on the classic skunk roots behind Big Bud.

Climate and Where to Grow It
Northern Lights x Big Bud Auto does best in a dry climate with warm days and low humidity. Its dense, chunky indica buds hold a lot of moisture, so a drier environment and steady airflow are important to keep them healthy right through to harvest.
As an autoflower it does not wait for shortening days to bloom, so you can start it almost any time in the warmer part of the year, and its short cycle lets you fit more than one run into a season. It stays compact at around 1.3 m, yet a single plant can bring in a big 600 g in a good spot, which is impressive for its size.
Indoors, keep daytime temperatures around 68–80°F (20–27°C) and, above all, keep humidity low as the heavy buds fill in. Good airflow through a well-managed canopy protects those dense, resinous flowers from damp.
Autoflower Growing Basics
With any autoflower, the key rule is that you do not switch the light schedule to trigger flowering. Northern Lights x Big Bud Auto begins to flower by itself at around 3 weeks of age, so run a long day of 18–20 hours of light from seedling right through to harvest.
Start the seed directly in its final pot. Autos run on a fixed internal clock and dislike transplanting, and with a short cycle there is little time to recover from a mid-run move. Keep training gentle: the vegetative window is brief, so favour light low-stress training over topping, bending branches to open the canopy rather than cutting into the plant.
Feeding Schedule (EC Guide)
This is a productive, hungry plant for its size, so you can feed it steadily through bloom to support the heavy buds, but still start low and build up as it asks. The EC values below track the short life-cycle stages rather than a separate veg-and-bloom switch.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Early weeks, raise nitrogen gently |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while the heavy buds swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Life Cycle and Harvest
The full life cycle runs about 8–10 weeks from seed to harvest, which is fast and predictable. As an auto you harvest when the plant is ready rather than on a fixed date, so let the trichomes guide you rather than counting from a light change.
Expect vegetative growth in the first weeks, the automatic switch to flower around week 3, and quick, heavy bud stacking through to the finish. The strong indica lean gives it dense, chunky, resinous flowers. Harvest when most trichomes are cloudy with a few amber for the fullest expression, and give the plant a short plain-water flush before cutting.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. A slow, even dry is especially important with buds this dense, so the inside does not stay damp while the outside dries.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure brings the earthy, spicy, incense-like character forward and smooths the smoke, which is exactly what this heavy indica cross deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Northern Lights x Big Bud Auto is a frosty, resinous plant, so the trim is excellent for dry sift, bubble hash or rosin, giving you a bonus run of concentrate from material most growers throw away.
Flavor and Terpenes
Northern Lights x Big Bud Auto has a rich, complex flavour of pine, spice, hashish, incense, musk and earth, a deep, old-school indica profile rather than a fruity or citrus-forward one. It is a resinous, almost savoury aroma with real character.
It carries a deep terpene stack. Six stand out: pinene drives the clean, fresh pine note; caryophyllene adds the peppery, spicy, incense-like warmth; myrcene anchors the earthy, musky, hashy base; humulene brings a woody, earthy depth; farnesene contributes a soft, green woodiness; and terpinolene adds a fresh lift. A touch of linalool rounds it off with a floral note.
Effects and Best Use
With its 70% indica base, Northern Lights x Big Bud Auto is reported as powerful, laid-back and deeply relaxing. It is a heavy-bodied, settling profile best kept for the evening or a quiet day off rather than an active schedule.
The medium 18–22% THC, paired with a notable 2% CBD, gives it a full but approachable strength, so it is potent without being overwhelming. That solid potency, the fast finish, the big yield for such a compact plant and the deep, spicy-earthy flavour make it a genuinely rewarding grow.
Common Problems and Pro Tips
Northern Lights x Big Bud Auto is a tough, forgiving grow, but it is a dense, heavy-yielding indica auto, so support and airflow come first.
- Train gently, not hard: as an autoflower it will not recover from heavy topping, so use low-stress bending while young and start it in its final pot.
- Support the big buds: it inherits Big Bud’s chunky, heavy colas, so the branches carry real weight late in bloom and benefit from staking or tying.
- Watch the humidity: as a 70% indica those dense buds trap moisture and it likes a drier climate, so keep humidity down and run a fan to avoid bud rot.
Expert tip: it throws deep, resinous, hashy buds, so the trim is worth saving for hash. A slow dry and a careful cure bring out its pine, spice, incense and earth character at its best.
Frequently Asked Questions
Is Northern Lights x Big Bud Auto indica or sativa?
It is strongly indica-dominant, at 70% indica and 30% sativa, which gives it a compact structure and a powerful, deeply relaxing effect. That indica build also means dense, chunky buds that trap moisture, so keep humidity down and run a fan through the canopy as the plant fills out.
How long is the life cycle?
About 8 to 10 weeks from seed to harvest. It flowers on age rather than on a light change, so the clock does not stop for mistakes, and it can be run all season. Plan your feed and training around that short, fixed window to get the most from this quick, heavy auto.
Do I need to change the light cycle?
No. Keep it on a long day of 18 to 20 hours of light from seedling to harvest. It starts flowering on its own at around three weeks, so there is no 12/12 flip to time. A steady, generous light schedule gives this heavy-yielding auto the energy to build its big, dense buds.
Is Northern Lights x Big Bud Auto good for beginners?
Yes. It is tough, quick and forgiving, which makes it beginner-friendly. Start it in its final pot to avoid transplant shock, keep humidity low in bloom since it prefers a drier climate, and support the heavy colas. Do that and it mostly looks after itself from seed to harvest.
What does it taste like?
Expect a deep blend of pine, spice, hashish, incense, musk and earth, driven by its pinene, caryophyllene, myrcene and humulene terpenes. It throws resinous, hashy buds, so the trim is worth saving, and a slow cure brings that complex, old-school character through at its best.
How much does it yield?
It is a strong producer for its size: 1.97 oz/ft² (600 g/m²) indoors, and around 21.16 oz (600 g) per plant outdoors in a good season. Strong support for the heavy Big Bud colas and good airflow help the plant finish that yield clean and heavy at harvest.
