Sweet Tooth vs Sweet Tooth Auto: Which Cannabis Seeds Should You Choose?

1. Introduction

Sweet Tooth and Sweet Tooth Auto share a common heritage but are built for slightly different growers and goals. Both offer the familiar Sweet Tooth genetics, but one is a fast-flowering, photoperiod feminized indica from Barneys Farm, while the other is an automatic hybrid from Seedsman that adds Lowryder #2 into the mix.

If you are a first-time grower, chasing strong effects, or comparing options for yield and ease of cultivation, understanding how these two versions differ will help you make a more confident purchase.

3. Sweet Tooth Overview (Barneys Farm)

Sweet Tooth by Barneys Farm is a feminized, indica-dominant strain created from Afghan, Nepali, and Hawaiian genetics. As a photoperiod variety, it relies on changes in light schedule to initiate flowering, which gives growers more control over plant size and veg time before switching to bloom.

One of the clear advantages of Sweet Tooth is its defined flowering window of around 8 weeks. For indoor growers planning their cycles, this relatively short bloom period makes it easier to schedule multiple harvests per year. Outdoors, this quicker finish can be useful in regions with shorter seasons or early autumn weather changes.

The strain is described as having a “good” yield, which positions it as a solid performer rather than a low-output option. While not quantified here, this generally indicates that, under reasonable conditions, Sweet Tooth can produce satisfying results without extreme techniques or highly optimised setups.

THC levels are described as “very strong,” making this version of Sweet Tooth particularly suitable for users seeking pronounced, intense effects. As an indica, many growers and consumers associate this type with more body-oriented experiences, but specific effect descriptions are not provided in the data. If you are looking for a potent strain where strength is a priority, the emphasis on high THC is a key point in Sweet Tooth’s favour.

As a feminized seed line, Sweet Tooth is designed to produce predominantly female plants, which helps reduce the need for sexing and culling males. This is particularly useful for new growers who want to make the most of their grow space without dealing with pollination risks.

4. Sweet Tooth Auto Overview (Seedsman)

Sweet Tooth Auto from Seedsman takes the core Sweet Tooth genetics (Afghani, Nepalese, Hawaiian) and crosses them with Lowryder #2 to create an autoflowering hybrid. The addition of Lowryder #2 is what gives this strain its automatic flowering trait, meaning it will begin to flower based on age rather than changes in light schedule.

As an auto, Sweet Tooth Auto is generally suited to growers who want a more straightforward cycle: plants can usually be grown under a consistent light schedule from seed to harvest. This can simplify the process, especially for beginners who are not yet familiar with managing light cycles for photoperiod strains.

Specific data on flowering time, yield, THC level, and detailed effects are not provided for Sweet Tooth Auto here. However, its hybrid nature and link to the original Sweet Tooth line suggest an aim to balance the core characteristics of Sweet Tooth with the convenience and speed associated with autoflowering genetics.

Because this is an autoflowering seed type, training and high-stress techniques are usually approached more carefully; many growers opt for simple, low-stress methods to avoid slowing the plant’s relatively fixed lifecycle. This can actually be a benefit for new growers who prefer a “less is more” approach to plant training and management.

5. Key Differences

General Comparison

The main structural difference between these two options is seed type and growth pattern. Sweet Tooth from Barneys Farm is a feminized, photoperiod indica, while Sweet Tooth Auto from Seedsman is an autoflowering hybrid with Lowryder #2 in the mix.

• Control vs. simplicity: Sweet Tooth (photoperiod) offers more control over plant size and timing, because you decide when to switch to flowering. Sweet Tooth Auto focuses on simplicity, progressing to bloom automatically without changing the light cycle.
• Genetic profile: Both varieties share Afghan, Nepali (or Nepalese), and Hawaiian lineage, but Sweet Tooth Auto adds Lowryder #2, which typically contributes the auto trait and influences plant structure and lifecycle.
• Type: Sweet Tooth is classified as an indica, whereas Sweet Tooth Auto is a hybrid. This suggests a broader genetic balance in the auto version, although specific effect details are not given.

Which Is Better for Beginners?

For a first-time grower, the best choice depends on what feels more manageable: learning light schedules or adapting to a fixed lifecycle.

• Sweet Tooth (feminized photoperiod) can be beginner-friendly if you are comfortable setting and adjusting light cycles. Its 8-week flowering period and good yield potential make it predictable once you grasp the basics. The feminized nature reduces the chance of unwanted males, which is another plus for novices.
• Sweet Tooth Auto (autoflowering) may appeal more to absolute beginners who want to avoid the complexity of changing lights for flowering. Autoflowers are often chosen by new growers for this reason: you can run the same light schedule from start to finish. On the other hand, you have less flexibility to correct mistakes because autos move through their stages on a fixed timeline.

If you prefer a more forgiving schedule where you can extend the vegetative phase to recover from early errors, Sweet Tooth photoperiod might be more suitable. If you want a “set and run” style grow without worrying about photoperiod changes, Sweet Tooth Auto could be the easier entry point.

Yield Comparison

Sweet Tooth is described as having a “good” yield, giving some indication that, under reasonable conditions, it can deliver satisfying harvests. While exact numbers are not provided, this is a positive signal for growers focused on productivity.

For Sweet Tooth Auto, specific yield data is not available here. Autoflowering strains often prioritise speed and convenience, and yields can vary based on environment, pot size, and grower experience. Without hard figures, it is safest to treat yield expectations as variable and dependent on setup and care.

If yield predictability is important and you value control over plant size and veg time, the photoperiod Sweet Tooth has the advantage of an indicated “good” output and a known 8-week bloom phase. Growers who are comfortable fine-tuning their growing conditions may be able to optimise this further.

Effects Comparison

For Sweet Tooth, the THC level is specified as “very strong,” which clearly identifies it as a strain aimed at users who prioritise intense psychoactive effects. As an indica, many consumers seek it for more grounded, body-focused experiences, although the exact effect profile is not described in the provided information.

Sweet Tooth Auto does not have THC strength or specific effects listed here. As a hybrid with the Sweet Tooth lineage, it’s reasonable to say it is designed to reflect some of the original character while incorporating autoflowering traits, but without precise THC data, it’s best not to assume it will match the “very strong” potency of the Barneys Farm version.

If strong effects are a deciding factor for you, Sweet Tooth with its clearly stated “very strong” THC is the more defined option. If you are open to a potentially more balanced or variable experience and place greater weight on ease of cultivation, Sweet Tooth Auto may still be attractive, even without quantified potency information.

6. Which Should You Choose?

When choosing between Sweet Tooth and Sweet Tooth Auto, consider your priorities in four main areas: grow difficulty, control, yield expectations, and desired strength of effects.

• Choose Sweet Tooth (Barneys Farm) if:
  • You want clearly defined “very strong” THC levels and are seeking powerful effects.
  • You prefer an indica classification and the type of experience commonly associated with it.
  • You value having a known 8-week flowering time to plan your grow cycles.
  • You’re comfortable managing a photoperiod light schedule, or willing to learn.
  • You want a feminized seed line that offers a “good” yield and reduces the need to remove male plants.
• Choose Sweet Tooth Auto (Seedsman) if:
  • You’d like the convenience of an autoflowering hybrid that doesn’t require changing light cycles.
  • You prefer a simpler, more streamlined grow where plants progress on their own schedule.
  • You’re a beginner who finds the idea of light management daunting and would rather focus on basic plant care.
  • You are interested in the Sweet Tooth genetic line but want it in an automatic format thanks to the Lowryder #2 cross.

For a first grow, both can work. If your main aim is maximum perceived strength and more control over plant development, the Barneys Farm Sweet Tooth stands out. If your main aim is simplicity and you’re comfortable with less precise information on yield and potency, Sweet Tooth Auto aligns better with those priorities.

7. Final Thoughts

Sweet Tooth and Sweet Tooth Auto share a recognizable genetic foundation but cater to different types of growers. The photoperiod, feminized Sweet Tooth from Barneys Farm offers “very strong” THC, a defined 8-week flowering time, and good yields for those who can manage light schedules. The Sweet Tooth Auto hybrid from Seedsman trades some of that defined data for the convenience of autoflowering genetics, appealing to growers who value straightforward cultivation.

By weighing your experience level, need for control, interest in strong effects, and expectations of yield, you can decide which version of Sweet Tooth fits your grow and your goals best.
