3. Big Devil FAST Version Overview

Big Devil FAST Version is a feminized hybrid created by Sweet Seeds by crossing Big Devil Auto with an undisclosed strain. The “FAST Version” label indicates it has been bred to reduce overall flowering time compared with typical photoperiod hybrids, while remaining a feminized, non-auto seed type.

As a hybrid, Big Devil FAST Version can be expected to lean toward a balanced profile between indica and sativa influences. While the exact effects and flavours are not specified in the available data, the strain is described as having strong THC levels. This makes it relevant for users looking for a noticeable, powerful experience rather than something mild.

There is no specific information on flowering duration, yield, or recommended growing style (indoor vs outdoor) in the current data. However, its hybrid nature and fast-line breeding suggest it aims to combine relatively quick finishing times with the versatility typical of many modern hybrids.

For new growers, the main advantages of Big Devil FAST Version are:

Feminized seeds, so you do not need to deal with male plants.
Hybrid type, which many beginners find more forgiving and adaptable to different environments.
Fast-line breeding, reducing the waiting time compared with standard photoperiod strains.

4. Black Muffin F1 Fast Version Overview

Black Muffin F1 Fast Version is another feminized fast strain from Sweet Seeds, but this one is classified as an indica. It is described as an “F1 Fast Version,” indicating breeding aimed at uniformity and quick flowering.

Here, we have more concrete data: Black Muffin F1 Fast Version has a flowering time of about 7 weeks. This clearly positions it as a rapid-finishing option, which can be particularly attractive for growers who want to harvest quickly or fit more cycles into a given time period.

In terms of potency, Black Muffin F1 Fast Version also falls into the strong category, with THC levels noted between 17 and 25 percent. This wide range covers moderate-high up to very high potency, making it suitable for users specifically searching for strong effects, provided they are comfortable with that level of intensity.

Although there is no yield or flavour information provided, its indica classification suggests it is likely aimed at those who appreciate the more grounded side of the cannabis spectrum, as opposed to a more energising, sativa-like profile. However, without explicit effect descriptions, it is safest to say that Black Muffin F1 Fast Version is a potent, fast-flowering indica-type option in the Sweet Seeds catalogue.

Key advantages for growers include:

Feminized seeds, simplifying plant selection.
Very clear flowering time of around 7 weeks.
Strong THC range (17–25%), appealing to users who prioritise potency.

5. Key Differences

General Comparison

The most fundamental difference between these two strains is their type: Big Devil FAST Version is a hybrid, while Black Muffin F1 Fast Version is an indica. For growers and users, this distinction often translates into differences in growth style and overall experience, even when THC levels are similar.

Black Muffin F1 Fast Version has a clearly defined flowering time of 7 weeks. Big Devil FAST Version is also presented as a quick strain, but with no exact flowering time stated. If having a precise schedule matters for your planning, Black Muffin offers more certainty on this point.

On the potency side, both are described as strong. Black Muffin F1 Fast Version goes a step further by specifying a THC range of 17–25%. Big Devil FAST Version is only noted as “strong,” so we can place it in a similar category without a specific percentage.

Which Is Better for Beginners?

For a first-time grower, both strains offer beginner-friendly elements because they are feminized and bred for faster flowering. However, their suitability differs slightly:

Big Devil FAST Version: As a hybrid, it may provide a more all-round growing and consumption experience. Many new growers appreciate hybrids because they are often adaptable and not overly specialised in one direction or the other. If you are unsure whether you prefer indica-leaning or more balanced effects, this hybrid route may feel safer.
Black Muffin F1 Fast Version: Its biggest beginner advantage is the clearly stated 7-week flowering time. That concreteness makes planning easier, especially if you are new to scheduling your grow. However, its strong THC range (up to 25%) may be intense for absolute beginners on the consumption side, so a cautious approach is advisable.

Overall, if your main concern as a beginner is predictable grow timing, Black Muffin F1 Fast Version has the edge. If you want a more generally balanced hybrid experience and are not working on a very tight schedule, Big Devil FAST Version may be more appealing.

Yield Comparison

Neither strain has specific yield figures listed in the available data, so a precise comparison is not possible. Both are presented as fast strains rather than explicitly “high-yield” lines, although fast-flowering varieties often aim to deliver reasonable productivity within a shorter time frame.

With that limitation in mind:

Big Devil FAST Version: Coming from a cross that includes Big Devil Auto, it is likely oriented towards combining speed with decent production, but without explicit numbers we cannot state whether it is higher or lower yielding than average.
Black Muffin F1 Fast Version: As an F1 Fast Version indica, it is designed for rapid flowering and uniformity, which can help consistency across plants. However, again, no yield data is provided, so we cannot firmly rate its output relative to Big Devil.

If yield is your top priority, it may be worth checking more detailed grow reports or breeder information beyond this basic product data for both strains. Based solely on what is available here, neither can be definitively called the higher yielder.

Effects Comparison

Both strains are in the strong THC category, with Black Muffin F1 Fast Version specifically listed at 17–25% THC. Big Devil FAST Version is simply described as strong-THC hybrid. Without detailed effect descriptions (such as whether they lean more relaxing, uplifting, or otherwise), we can only draw cautious distinctions based on their type.

Big Devil FAST Version (Hybrid): Hybrid strains often aim for a balanced experience, combining aspects associated with both sides of the spectrum. For users who want versatile effects suitable for a wider range of situations, a hybrid like Big Devil FAST Version is often attractive, especially when paired with strong THC content.
Black Muffin F1 Fast Version (Indica): Indica strains are usually chosen by people who prefer a more grounded, body-oriented type of experience. Given its strong THC range, Black Muffin F1 Fast Version will likely feel robust, and could be most appealing to those who clearly know they enjoy indica-dominant profiles.

For users specifically seeking strong effects, both options qualify. The deciding factor is whether you favour a more balanced hybrid approach (Big Devil FAST Version) or a firmly indica-type strain (Black Muffin F1 Fast Version).

6. Which Should You Choose?

Your choice between Big Devil FAST Version and Black Muffin F1 Fast Version should come down to your priorities as both a grower and consumer.

Choose Big Devil FAST Version if:
- You want a hybrid with a potentially more balanced overall profile.
- You like the idea of a fast, feminized strain derived from Big Devil Auto genetics.
- You are a beginner who prefers a flexible, all-round option rather than a clearly indica-focused one.
Choose Black Muffin F1 Fast Version if:
- You need a clearly defined, very quick flowering time (around 7 weeks).
- You specifically want an indica-type strain.
- You are looking for strong effects with a clearly stated THC range of 17–25%.
- You appreciate fast, uniform F1-style genetics and care about predictable crop timing.

For a first grow where timing and ease of planning are critical, Black Muffin F1 Fast Version’s 7-week flowering window stands out. For someone still exploring what kind of effects they prefer, the hybrid nature of Big Devil FAST Version offers a more generalist starting point.

7. Final Thoughts

Both Big Devil FAST Version and Black Muffin F1 Fast Version are strong, fast, feminized strains from Sweet Seeds designed to shorten the wait between planting and harvest. Black Muffin F1 Fast Version offers more concrete data, particularly on flowering time and THC percentage, making it appealing to growers and users who value predictability and potent indica effects. Big Devil FAST Version, as a hybrid with fast-line breeding and strong THC, will be more attractive to those seeking a broadly balanced, versatile option.

If you are comparing these strains before purchase, focus on whether you want a defined 7-week indica or a flexible hybrid experience. Align that with how quickly you need to harvest and how strong you want the effects to be, and the right choice between these two fast Sweet Seeds strains will become clear.
