3. Northern High Lights Overview

Northern High Lights from Advanced Genetics Seeds is a feminized hybrid aimed at growers who want strong THC levels and a straightforward flowering period. Being a feminized photoperiod strain means plants are bred to produce female flowers and will start blooming when they receive a shorter light cycle, either outdoors with the seasons or indoors when you adjust your lights.

The strain’s flowering time is listed at around 7–8 weeks, which is on the quicker side for many hybrid photoperiods. For growers focused on turnaround time, this relatively short bloom period can make planning successive harvests easier. The yield is described as “good”, indicating respectable production without positioning it as an extreme heavy-yielder that demands advanced techniques.

Northern High Lights is noted for a subtle aroma, which is useful if you prefer less presence during the grow or want something easier to manage with basic odour control. While there is no detailed effect description, the THC level is described as strong. Combined with its hybrid nature, you can reasonably expect pronounced effects rather than something very light or gentle. This makes Northern High Lights well-suited to users specifically looking for powerful potency from their harvest.

Overall, Northern High Lights fits growers who want:

• A feminized, non-auto seed they can control with light schedule
• Good yields in a relatively short 7–8 week flowering window
• Strong THC for pronounced effects
• A more discreet, subtle-smelling grow

4. Northern Lights Auto Overview

Northern Lights Auto from G13 Labs is an autoflowering version of the classic line. It’s created by crossing Original Northern Lights with Ruderalis, which introduces the ability to flower automatically without relying on a change in light cycle.

As an auto strain, Northern Lights Auto will move from seedling to flowering on its own, making it particularly appealing to new growers or anyone who doesn’t want to manage complex lighting schedules. You can usually keep autos under the same light cycle from start to finish, which simplifies indoor setups and makes balcony or small-space grows more straightforward.

The strain type is indica, so you can expect it to lean towards the traditional Northern Lights profile, although the exact effects are not specified. The breeder notes a relatively mild aroma, which, like Northern High Lights, makes it a sensible choice if smell control is a consideration in your grow space. Yield is described as “good”, so you can expect decent production for an auto, without explicit claims of very high or very low output.

Key points for Northern Lights Auto:

• Autoflowering seeds derived from Original Northern Lights crossed with Ruderalis
• Indica-leaning profile, though specific effects are not detailed
• Good yield potential for an auto strain
• Relatively mild aroma for more discreet grows
• Simplified lighting requirements, ideal for those seeking ease of cultivation

5. Key Differences

General Comparison

The most fundamental difference between Northern High Lights and Northern Lights Auto is seed type. Northern High Lights is a feminized photoperiod hybrid, while Northern Lights Auto is an autoflowering indica. This impacts how you grow them and the level of control you have over vegetative growth and flowering.

With Northern High Lights, you decide when the plant starts flowering by changing the light cycle (indoors) or relying on natural seasonal changes (outdoors). This can allow for a longer vegetative phase if you want to train plants or aim for slightly larger harvests from each one. The trade-off is that it requires more active management of light and timing.

With Northern Lights Auto, the plant will trigger flowering on its own after a certain age, regardless of light schedule. This removes one layer of complexity for new growers, but it means less flexibility in veg time and plant size.

Which Is Better for Beginners?

For absolute first-time growers, Northern Lights Auto usually offers a more straightforward path. Autos are popular starter strains because they:

• Do not require a change in light cycle to initiate flowering
• Are generally grown under a simple, consistent light schedule
• Allow you to focus on basic watering, feeding, and environment rather than timing

If you want the simplest possible setup with minimal decisions about when to flip to flower, Northern Lights Auto has the edge.

However, Northern High Lights is still quite beginner-friendly. The feminized seeds reduce the need to identify and remove male plants, and the 7–8 week flowering time is relatively short. If you’re comfortable adjusting a timer or relying on the seasons outdoors, and you’d like a bit more control over plant size and training, Northern High Lights can be a good first photoperiod choice.

In short:

• Choose Northern Lights Auto if you want the least technical decision-making and a more “set-and-go” grow.
• Choose Northern High Lights if you don’t mind managing light cycles and want a first experience with a traditional feminized photoperiod hybrid.

Yield Comparison

Both strains are described as offering a “good” yield, so neither is positioned as low-yielding. Specific grams per square metre or per plant are not provided, so it’s more useful to look at context.

Northern High Lights, as a feminized photoperiod hybrid, often allows growers to extend the vegetative phase, use training methods, and potentially push plants a bit larger before flowering. That flexibility can help maximise yield per plant if you’re willing to invest time in training and plant care.

Northern Lights Auto, being an autoflower, has a more fixed lifecycle. Autos typically stay more compact and finish faster overall, but that can mean smaller individual plants compared to fully vegged photoperiods. Within that framework, a “good” yield for an auto is attractive, especially if you value quick, straightforward harvests rather than maximising every gram.

If your main objective is to squeeze as much as possible from each plant and you don’t mind a bit more involvement, Northern High Lights may offer more potential through training and veg-time control. If you prefer to keep things simple and accept what the plant naturally gives on an auto timetable, Northern Lights Auto is better aligned with that goal.

Effects Comparison

Detailed effect descriptions are not provided for either strain, so any comparison has to rely on the limited data available and general expectations.

Northern High Lights is a hybrid with strong THC. That suggests a more intense experience suited to users actively seeking pronounced effects. Being a hybrid, it can reasonably be expected to balance some characteristics that are typically associated with both indica and sativa lines, although the exact profile is not specified.

Northern Lights Auto is classified as an indica derived from Original Northern Lights crossed with Ruderalis. While the specific THC content and effect strength are not listed, indica strains from this family are generally chosen by users who enjoy the classic Northern Lights style. Without hard data, it’s safest to say Northern Lights Auto is likely to provide a more traditionally indica-leaning experience, but its exact intensity is unknown from the provided information.

For a user specifically looking for strong, noticeable effects, the clearer signal comes from Northern High Lights, as it is explicitly described as having strong THC. For someone prioritising the Northern Lights legacy in an easy auto format without a stated potency, Northern Lights Auto still holds appeal, but with less concrete information on strength.

6. Which Should You Choose?

Your choice between Northern High Lights and Northern Lights Auto should be based on how much control you want over the grow, your comfort with lighting schedules, and how strongly you prioritise potency versus simplicity.

• Pick Northern High Lights if:
  • You want a feminized photoperiod hybrid with strong THC.
  • You’re comfortable managing – or willing to learn about – light schedules to trigger flowering.
  • You’d like the option to extend veg time and potentially train plants for better per-plant yield.
  • You appreciate a subtle aroma that’s easier to keep under control.
• Pick Northern Lights Auto if:
  • You’re a first-time grower who wants a simple, autoflowering strain.
  • You prefer to keep one light schedule from seed to harvest, with minimal adjustments.
  • You like indica-leaning plants with a Northern Lights background.
  • You want good yields from a compact, relatively low-odour auto.

For a beginner who feels unsure about managing light cycles, Northern Lights Auto is usually the safer and easier starting point. For a new grower who already understands basic lighting or is willing to learn, and who wants clearly strong THC, Northern High Lights offers a more traditional photoperiod experience.

7. Final Thoughts

Both Northern High Lights and Northern Lights Auto deliver the key qualities that have made the Northern Lights family so popular: manageable plants, good yields, and discreet aroma. The decision mainly comes down to whether you want an autoflowering indica that simplifies the process, or a feminized hybrid with strong THC and more control over growth.

If you prioritise ease of cultivation and a hassle-free first grow, Northern Lights Auto is likely to suit you best. If you aim for stronger effects and are ready to handle a photoperiod schedule, Northern High Lights is a solid alternative. Either way, both strains provide a practical route into growing for beginners and experienced cultivators alike.
