Northern Light Auto vs Northern Light: Which Seeds Are Right for You?
1. Introduction
Northern Light is one of the most recognisable indica names in cannabis, and many growers eventually consider adding a version of it to their garden. On this page, we’re comparing two closely related but quite different options: Northern Light Auto by Royal Queen Seeds and Northern Light feminized by Bulldog Seeds.
Both are indica strains with “good” yield potential, but they differ in seed type, genetics, and THC strength. Understanding these differences is especially important if you are a first-time grower, someone who prioritises high yields, or a buyer looking for strong effects.

3. Northern Light Auto Overview
Northern Light Auto from Royal Queen Seeds is an autoflowering indica based on classic Northern Lights genetics crossed with ruderalis. This combination keeps the indica character while adding the automatic flowering trait, meaning plants transition to flowering on their own regardless of light schedule.
As an auto, Northern Light Auto is typically chosen by growers who want a simpler cultivation experience. You do not need to switch light cycles to trigger flowering, which can make planning and timing more straightforward, especially if you are setting up a small home grow or using a single grow space for the entire cycle.
The breeder describes the yield as “good,” placing it in a productive range for an autoflowering plant. While exact figures are not given, it is positioned as a solid performer rather than a low-yielding compact strain. The THC level is described as “strong,” so users can expect a clearly noticeable potency for an indica variety, while still leaving a little headroom below the “very strong” category of its photoperiod counterpart.
The flavour and aroma profile is listed as confidential, so specific tasting notes are not available. However, given its Northern Lights background, growers typically choose this strain for a classic indica experience combined with the convenience of an auto. Its automatic nature and indica structure often make it attractive to beginners who want to focus on learning the basics of watering, nutrition, and environment without worrying about light schedule manipulation.
4. Northern Light Overview
Northern Light by Bulldog Seeds is a feminized, photoperiod version that blends several well-known lines: Skunk Number One, Northern Lights, and El Niño. This more complex genetic background still results in an indica-type plant but with influences from these additional parent strains.
As a feminized photoperiod seed, this Northern Light requires a change in light cycle (typically from a longer “vegetative” schedule to a 12/12 schedule) to start flowering. The stated flowering time is around 8 weeks. That gives growers a clear idea of the flowering phase length, which can be useful for planning harvests, especially if you already understand light schedules.
Yield is again listed as “good,” suggesting that, when grown in suitable conditions with proper care, this strain can produce a solid harvest. In many gardens, photoperiod indica strains with this kind of background are grown for a balance of manageable plant size and worthwhile yield, and this version fits into that general category.
THC is described as “very strong,” making this option more suitable for users who specifically seek powerful effects and already have some tolerance or experience. If potency is your top priority, this is a key differentiating factor compared with Northern Light Auto. While no detailed flavour or effect notes are provided, the mix of Skunk, Northern Lights, and El Niño genetics suggests that this is designed as a robust, impactful indica-type strain rather than a mild option.
5. Key Differences
General Comparison
At a glance, the main differences between these two seeds are seed type, genetic composition, and THC strength. Northern Light Auto is an autoflowering indica derived from Northern Lights and ruderalis, while Bulldog’s Northern Light is a feminized indica combining Skunk #1, Northern Lights, and El Niño.
The auto version focuses on simplicity and time-based flowering, making it easy to fit into almost any light schedule. The feminized version gives growers more control over plant size and timing by using the traditional photoperiod cycle, which can be an advantage for more experienced cultivators who want to shape their plants through extended veg times and training.
Which Is Better for Beginners?
For a first-time grower, the automatic flowering of Northern Light Auto is a major advantage. You do not need to plan or manage a separate vegetative and flowering light schedule; the plants will move through their life cycle on their own. This reduces one of the biggest early learning hurdles and allows you to focus on environment control and basic plant care.
The feminized Northern Light requires more direct management: you must know when to change the light schedule to trigger flowering and how long to keep plants in the vegetative phase. For beginners who want to deeply learn traditional cannabis cultivation, this can be a positive challenge, but it is less “plug-and-play” than the auto.
So, for an absolute beginner seeking the easiest route, Northern Light Auto is usually the more accessible choice. If you are a novice but already comfortable with the idea of controlling light cycles, Bulldog’s Northern Light can still be a reasonable entry, especially if you prefer the flexibility of a photoperiod plant.
Yield Comparison
Both strains are rated as offering a “good” yield. Since no precise numbers are given, it is more useful to look at how yield relates to plant type and grow style.
- Northern Light Auto: As an autoflower, it tends to prioritise speed and convenience alongside decent productivity. You get a “good” yield in a relatively straightforward grow, with less need to manage plant training and veg duration.
- Northern Light (feminized): Also described as “good” yielding, this strain’s photoperiod nature allows growers to extend the vegetative stage if desired, potentially increasing plant size and overall harvest in suitable conditions.
If you are experienced with training and want to optimise every square metre, the feminized Northern Light may offer more flexibility to push yields by controlling plant size and structure. If you prefer a simpler run with fewer decisions, Northern Light Auto gives you a solid yield without as much planning.
Effects Comparison
Specific effect descriptions are not provided for either strain, but both are indica types, so growers and buyers naturally expect an indica-style experience. The main clear difference in this area is potency:
- Northern Light Auto: Rated as having “strong” THC. This positions it as potent, but not at the very top end of the scale.
- Northern Light (feminized): Marked as “very strong” THC, indicating a more intense effect level.
If you are sensitive to THC or still learning how different strengths affect you, Northern Light Auto may provide a more manageable starting point while still being clearly powerful. If you already know you enjoy high-THC indicas and are specifically shopping for something very strong, Bulldog’s Northern Light is more closely aligned with that goal.
6. Which Should You Choose?
Choosing between these two Northern Light versions comes down to your priorities as a grower and consumer.
- Choose Northern Light Auto if:
- You are a first-time grower and want to avoid managing light schedule changes.
- You prefer a straightforward, time-based grow with fewer variables.
- You want a strong indica but do not necessarily need the maximum possible THC intensity.
- You value a good yield without having to fine-tune plant training and veg length.
- Choose Northern Light (feminized) if:
- You are comfortable managing vegetative and flowering light cycles.
- You want more control over plant size and timing by adjusting veg duration.
- You are specifically looking for very strong THC effects from an indica.
- You are interested in working with a more complex genetic mix that includes Skunk #1 and El Niño.
If you fit into the “beginner looking for easy cultivation” category, Northern Light Auto is likely better aligned with your needs. If you consider yourself a user “looking for strong effects” and you are willing to handle the slightly more involved cultivation process, Bulldog’s Northern Light is the more suitable option.
7. Final Thoughts
Both Northern Light Auto by Royal Queen Seeds and Northern Light feminized by Bulldog Seeds offer a way to experience classic indica genetics with reliable, “good” yield potential. The auto version focuses on ease and simplicity, while the feminized version leans into higher THC strength and grower control.
By weighing how comfortable you are with light schedules, how much potency you want, and how involved you want to be in plant training and timing, you can choose the Northern Light variant that best matches your experience level and goals.
