Green Poison FAST Version Overview

Green Poison FAST Version is a feminized hybrid created by Sweet Seeds by crossing their Green Poison with Green Poison Auto. As a “FAST Version” strain, it is bred to complete its flowering stage more quickly than the original photoperiod line, which is especially appealing to growers who want to shorten their cycle without fully moving to an autoflower.

Because it is a hybrid, Green Poison FAST Version can potentially balance characteristics associated with both indica- and sativa-leaning plants, though the exact effect profile is not specified in the available data. Its genetics, combining the standard Green Poison with an autoflowering counterpart, usually point toward quicker finishing times and a more compact overall schedule, which many growers with limited time or seasonal outdoor windows find useful.

The THC level, flavour, yield and specific cultivation preferences are not listed in the current product details. For this reason, it is best viewed as a flexible, general-purpose fast hybrid from Sweet Seeds rather than a strain chosen for one narrow use. If you are browsing fast-flowering feminized seeds and prefer a hybrid background with known Green Poison lineage, this option may appeal.

Since the seeds are feminized, growers can expect plants that are highly likely to be female, which simplifies planning for beginners and experienced cultivators alike. Even without precise technical figures, Green Poison FAST Version stands out primarily for its established Green Poison heritage and its fast-flowering design.

Black Muffin F1 Fast Version Overview

Black Muffin F1 Fast Version is also a feminized fast strain from Sweet Seeds, but with a different profile. It is classified as an indica, and the product information highlights a strong THC content, in the range of about 17 to 25 percent. This places it clearly in the higher potency category compared with many standard strains.

This F1 Fast Version has a specified flowering time of around 7 weeks, giving growers a clear idea of how quickly it can be ready for harvest once flowering begins. That relatively short indoor flowering period is a key advantage for those who want to fit more runs into a year or who must finish before poor outdoor weather sets in.

The exact genetics behind Black Muffin F1 Fast Version, as well as detailed notes on flavour profile, yield, and grow difficulty, are not provided. However, the indica classification combined with the strong THC range suggests that it is aimed at users who prioritise robust, noticeable effects. For growers, the feminized nature again means fewer concerns about male plants and a more straightforward cultivation plan.

In essence, Black Muffin F1 Fast Version positions itself as a fast, potent indica option from Sweet Seeds, with a clearly defined flowering window and a notably strong THC range for those who care most about intensity.

Key Differences

General Comparison

At a general level, the two strains differ in their type and the clarity of their available data:

Type: Green Poison FAST Version is a hybrid, while Black Muffin F1 Fast Version is an indica. This distinction can influence plant structure and the nature of the effects, though specific effect notes are not listed for either product.
Lineage and positioning: Green Poison FAST Version is clearly tied to the well-known Green Poison line and its autoflower version, making it attractive to those who already appreciate that family. Black Muffin F1 Fast Version is presented more as a distinct F1 Fast indica option with a focus on potency.
Information detail: Black Muffin F1 Fast Version has precise THC information (strong, about 17–25%) and a specific flowering time (around 7 weeks). Green Poison FAST Version is identified as fast, but without exact figures in the available data.

Which Is Better for Beginners?

For a first-time grower, two factors usually matter most: simplicity and predictability. Both strains are feminized, which already makes them more beginner-friendly because you are less likely to deal with unwanted male plants.

Green Poison FAST Version, as a hybrid, may appeal to beginners who want a more general-purpose introduction to growing fast photoperiod seeds, especially if they are familiar with or curious about Green Poison genetics. However, the lack of specific information on flowering duration, yield, and potency means new growers must be comfortable with some uncertainty when planning their grow.

Black Muffin F1 Fast Version may suit beginners who value clear expectations. Knowing that flowering takes about 7 weeks allows more precise scheduling, which is useful if you are coordinating around holidays, outdoor climates, or grow room capacity. The main caution for completely new users is the strong THC level; while that is an advantage for experienced consumers, it may be intense for someone who is also new to consumption.

In summary:

Growing-only beginners who are comfortable adjusting their own consumption might lean toward Black Muffin F1 Fast Version for its predictable 7-week flowering time.
Beginners seeking a familiar hybrid lineage and not focused on exact timing details may prefer Green Poison FAST Version.

Yield Comparison

Neither product listing provides explicit yield figures, so a direct numerical comparison is not possible. What we can say is:

Both are fast versions, which typically aim to balance quicker finishing with reasonable yields, rather than maximising one at the total expense of the other.
Green Poison FAST Version’s hybrid background from Green Poison and its autoflower line may suggest a design that keeps yields competitive while shortening bloom times, but no specific data is provided.
Black Muffin F1 Fast Version’s 7-week flowering schedule indicates a clear focus on speed. Without yield numbers, growers should treat it as a solid, fast indica option rather than choosing it solely for maximum production.

If yield is your top priority, it can be useful to consider how the stated fast flowering fits into your overall annual production: fitting one extra cycle into a year can sometimes compensate for slightly lower per-plant yields, even when figures are not published.

Effects Comparison

Detailed effect descriptions are not listed for either strain in the available data, so it is important not to make assumptions about specific sensations or uses. However, there are still some meaningful distinctions:

Type-based expectations: As an indica, Black Muffin F1 Fast Version is often chosen by people who associate indicas with certain types of experiences. Green Poison FAST Version, being a hybrid, is more of a middle-ground choice for those who do not want to commit firmly to one end of the spectrum.
Potency: Black Muffin F1 Fast Version is specifically noted as having strong THC, approximately 17–25%. This clearly targets users who seek pronounced, intense effects. Green Poison FAST Version does not have THC data listed, so it should not be selected on the assumption of any particular strength.

For users who prioritise strong effects, Black Muffin F1 Fast Version stands out because its potency range is clearly stated, while Green Poison FAST Version is better seen as a versatile hybrid option without a defined THC benchmark.

Which Should You Choose?

Your choice between Green Poison FAST Version and Black Muffin F1 Fast Version should be guided by your main priorities as both a grower and a consumer.

Choose Green Poison FAST Version if:
- You want a fast-flowering hybrid with direct Green Poison lineage.
- You are comfortable working without exact THC or flowering-time figures and value a more flexible hybrid background.
- You like the idea of a strain that combines a classic photoperiod line with an autoflower version to shorten the cycle.
Choose Black Muffin F1 Fast Version if:
- You prioritise strong, clearly specified potency, with THC around 17–25%.
- You want a fast indica with a well-defined flowering period of about 7 weeks.
- You appreciate having concrete timing data to plan your grow, especially if you are limited by season or space.

For a first-time grower who also seeks powerful effects, Black Muffin F1 Fast Version may be the more straightforward choice due to its combination of fast bloom and strong THC information. For someone who wants to experiment with a fast hybrid rooted in a known line, Green Poison FAST Version offers a different kind of appeal.

Final Thoughts

Both Green Poison FAST Version and Black Muffin F1 Fast Version occupy a similar niche as feminized fast strains from Sweet Seeds, but they cater to slightly different needs. The hybrid Green Poison FAST Version focuses on established genetics and flexibility, while Black Muffin F1 Fast Version emphasises a short, defined flowering time and strong THC levels in an indica format.

If your main concern is potency and precise timing, Black Muffin F1 Fast Version is likely the better fit. If you value a hybrid heritage and are drawn to the Green Poison family, Green Poison FAST Version is worth serious consideration. In both cases, you get feminized seeds designed to save time in the flowering room, leaving you to decide which profile best matches your growing style and desired experience.
