3. Sweet Tooth Overview (Barneys Farm)
Barneys Farm’s Sweet Tooth is a feminized, indica-dominant strain created from Afghan, Nepali, and Hawaiian genetics. As a photoperiod plant, it follows a traditional light-cycle schedule: it will stay in the vegetative stage until you switch the lights (indoors) or until natural daylight shortens (outdoors). Once flowering begins, it takes around 8 weeks to finish.
The breeder describes the yield simply as “good,” which suggests Sweet Tooth is designed to produce a solid harvest when grown in suitable conditions and given basic care. For growers focused on getting a reliable amount from each plant rather than experimenting with more finicky genetics, this can be an advantage.
With THC described as “very strong,” Sweet Tooth is aimed at users who want pronounced effects rather than something mild. While specific effects are not listed, its indica classification and Afghan/Nepali background usually point growers toward expecting a more body-oriented, deeply relaxing profile rather than a purely energetic one. This makes it appealing to those who want strong, robust effects at the end of the day.
As a feminized seed line, Sweet Tooth is intended to produce female plants, which simplifies things for new and experienced growers alike by largely removing the need to identify and remove males. However, because it is a standard photoperiod strain, it does require some understanding of light schedules, plant training, and timing to get the most from its good yield and strong potency.
4. Sweet Tooth Auto Overview (Seedsman)
Sweet Tooth Auto from Seedsman is an autoflowering hybrid created by crossing Sweet Tooth with Afghani, Nepalese, Hawaiian, and Lowryder #2. The addition of Lowryder #2 gives it the autoflowering trait, which means it will begin flowering automatically based on age rather than relying on a change in light schedule.
Because it is a hybrid that mixes the original Sweet Tooth line with Lowryder #2, you can expect a more balanced genetic profile compared to the indica nature of the original. The precise effects and THC level are not specified, but the underlying Sweet Tooth, Afghan, Nepalese, and Hawaiian components suggest it is still intended to deliver noticeable, characterful effects rather than something overly subtle.
As an auto, Sweet Tooth Auto is typically aimed at growers who want a more straightforward cultivation process. You do not need to change the light cycle to trigger flowering, which can be especially helpful for first-time growers, small indoor setups, or people who want a quicker seed-to-harvest turnaround without managing multiple lighting stages.
Although no exact flowering time or yield data is given, autoflowering hybrids like this are often chosen for their simplicity rather than chasing maximum potential yield per plant. For many beginners, the trade-off can be worthwhile: fewer cultivation decisions in exchange for a more predictable, beginner-friendly grow.
5. Key Differences
General Comparison
The most fundamental difference lies in seed type and genetics. Sweet Tooth from Barneys Farm is a feminized, indica strain with Afghan, Nepali, and Hawaiian origins. It is a classic photoperiod cultivar with an 8-week flowering window and a “very strong” THC description, backed by a “good” yield.
Sweet Tooth Auto from Seedsman, on the other hand, is an autoflowering hybrid that adds Lowryder #2 to the Sweet Tooth, Afghani, Nepalese, and Hawaiian lineage. This Lowryder #2 influence gives it the ability to flower automatically, making it structurally different to grow even if the flavour and effect family is related to the original Sweet Tooth.
Which Is Better for Beginners?
For someone completely new to growing, Sweet Tooth Auto has some inherent advantages simply because it is an autoflower:
- It does not depend on changing light schedules to begin flowering.
- You can usually keep a consistent light cycle from seed to harvest.
- This reduces the number of cultivation decisions and timing mistakes.
This makes Sweet Tooth Auto potentially more forgiving if you are setting up your first grow, especially indoors or in a small space where managing multiple light cycles is complicated.
However, Sweet Tooth as a feminized photoperiod strain has its own beginner-friendly aspects:
- Feminized seeds help you avoid male plants, simplifying selection.
- An 8-week flowering time is relatively manageable and not excessively long.
- Photoperiod plants give you more control over how long to vegetate, which can be useful if you want to learn plant training and canopy management.
If your main priority is the simplest possible process with minimal technical decisions, Sweet Tooth Auto is likely easier for a first grow. If you are a beginner who wants to learn more traditional growing skills and is comfortable managing a light switch to start flowering, Sweet Tooth can be a better learning tool with more control over plant size and timing.
Yield Comparison
Barneys Farm lists Sweet Tooth’s yield as “good,” which indicates it is bred to provide a respectable harvest under normal conditions. Growers who want a reliable amount from each plant and have the ability to give it at least competent care might prefer this predictable performance.
For Sweet Tooth Auto, no specific yield figure is given. In general, autoflowering hybrids are often chosen for speed and ease rather than strictly for maximum per-plant output. Without exact data, it is safest not to assume Sweet Tooth Auto will outperform Sweet Tooth in terms of sheer yield, especially since Sweet Tooth is explicitly described as giving a good return.
If your priority is extracting as much as possible from each plant and you are comfortable managing a photoperiod cycle, Sweet Tooth has the clearer yield indication. If your focus is more on an uncomplicated grow with acceptable but unspecified production, Sweet Tooth Auto may still be attractive despite the lack of published yield information.
Effects Comparison
Only Sweet Tooth has explicit potency information: THC is described as “very strong.” Combined with its indica classification and Afghan/Nepali base, this points growers toward expecting pronounced, heavy effects rather than a light or subtle experience. This can appeal to users specifically seeking powerful, impactful sessions.
For Sweet Tooth Auto, no THC level or specific effects are stated. Its genetic makeup includes Sweet Tooth, Afghani, Nepalese, Hawaiian, and Lowryder #2, suggesting it aims to preserve much of the original Sweet Tooth character while adding autoflowering traits. However, without clear THC data, it is not possible to directly compare potency.
If strong effects are a high priority and you want the option whose potency is actually documented as “very strong,” Sweet Tooth stands out. If you are open to a hybrid autoflower whose exact strength is unspecified but shares much of the same ancestry, Sweet Tooth Auto may still meet your needs, especially if convenience in growing is more important than chasing maximum potency.
6. Which Should You Choose?
The better choice depends on what you value most: ease of cultivation, yield consistency, or strength of effects.
- Best for complete beginners: If you want a simple, low-maintenance introduction to growing with minimal concern about light schedules, Sweet Tooth Auto is generally more beginner-friendly. The autoflowering trait reduces decision points and makes it easier to succeed on your first attempt.
- Best for learning classic growing skills: If you are a new grower but keen to learn more about controlling plant size, veg time, and flowering triggers, Sweet Tooth is a good entry into standard photoperiod cultivation. You gain more control, at the cost of slightly more complexity.
- Best for growers focused on high or reliable yield: Sweet Tooth is the only one with yield described (“good”), so if your priority is choosing the option with a stated production potential, the feminized Sweet Tooth has the clearer advantage.
- Best for users seeking strong effects: Sweet Tooth is explicitly described as having “very strong” THC, making it the safer pick if you are specifically looking for powerful effects and want this confirmed trait when choosing seeds.
- Best balance of ease and versatility: If you are comfortable trading some yield certainty and clearly stated potency for easier cultivation and automatic flowering, Sweet Tooth Auto offers that balance as a hybrid autoflower.
7. Final Thoughts
Sweet Tooth and Sweet Tooth Auto cater to slightly different growers, even though they share much of the same genetic background. The original Sweet Tooth from Barneys Farm is ideal if you want a photoperiod indica with a “good” yield and confirmed very strong THC, and you are willing to manage light cycles. Sweet Tooth Auto from Seedsman is more suited to those who prioritise simplicity and the convenience of autoflowering genetics, even without specific yield or THC data.
If you are a first-time grower focused on ease, Sweet Tooth Auto is likely the better starting point. If you want strong, clearly documented potency and a solid harvest from a classic indica, Sweet Tooth may be the more satisfying long-term choice.
