3. Big Devil #2 Overview

Big Devil #2 is an autoflowering hybrid from Sweet Seeds, bred from an enhanced Large Devil autoflower line. As an auto, it moves through its entire life cycle without needing changes to the light schedule, which can make planning and execution easier for new growers.

The strain is noted for delivering a good yield for an autoflower, which appeals to growers who want respectable harvests without taking on a demanding project. With a strong THC profile and hybrid genetics, Big Devil #2 is aimed at users looking for pronounced, robust effects rather than something mild or subtle.

One of the distinct features is its flavour and aroma: sweet and pungent with a hint of skunk. This combination can be attractive if you appreciate classic skunky notes backed by a sweeter edge. Because it is an autoflower, it will start to flower automatically after a short vegetative period, which reduces the need for technical control over light cycles.

Overall, Big Devil #2 sits in the space between ease of cultivation and solid productivity, making it a practical option for a first grow where you still want a potent end result.

4. Big Devil FAST Version Overview

Big Devil FAST Version is Sweet Seeds’ feminized, fast-flowering take on the Big Devil line. It is created by crossing Big Devil Auto with a secret strain, resulting in a hybrid that keeps the Big Devil character while adapting it to a photoperiod, fast version format.

As a feminized photoperiod strain, it requires a change in light schedule to trigger flowering, unlike its autoflowering counterpart. “FAST” versions are typically designed to finish more quickly than standard photoperiod strains, but specific flowering times and yield data for this particular variety are not provided here.

Big Devil FAST Version also features strong THC, so it is geared towards users who want noticeable, powerful effects. While flavour and aroma details are not listed, its link to Big Devil Auto suggests it is intended for those who already appreciate the Big Devil family profile and want a faster, photoperiod-friendly variant.

This strain may be more attractive to growers who already understand basic light management and want a quicker-turnaround feminized hybrid that still offers robust potency.

5. Key Differences

General Comparison

The main dividing line between these two strains is autoflower vs. fast photoperiod:

• Big Devil #2 is an autoflowering hybrid. It doesn’t rely on a change in light schedule to start flowering, which usually simplifies the process and shortens the overall cycle compared to many traditional photoperiods.
• Big Devil FAST Version is a feminized photoperiod hybrid. It still needs a switch to a flowering light cycle, but as a “fast” version it is bred to finish quicker than typical photoperiod strains related to Big Devil.

If you want a set-and-forget style grow with fewer timing decisions, the auto format of Big Devil #2 is more forgiving. If you prefer control over the vegetative period and are comfortable managing light schedules, the FAST Version gives you that flexibility in a shorter-than-usual photoperiod package.

Which Is Better for Beginners?

From a cultivation perspective, beginners often look for strains that are straightforward to manage and tolerant of small mistakes.

• Big Devil #2 is typically more suitable for first-time growers because its autoflowering nature removes the need to plan the switch from vegetative to flowering light schedules. You can keep a simple light routine, and the plant will take care of the rest.
• Big Devil FAST Version may be better for growers who have at least a basic understanding of indoor growing or light management. While it is shorter in flowering time compared to standard photoperiods, you still need to control when flowering begins, which adds a step for complete beginners.

If this is your very first grow and you want to minimise variables, Big Devil #2 is generally the more beginner-friendly choice. If you’re a newer grower who is already comfortable switching light cycles, the FAST Version can be a next step that offers more control over plant size and timing.

Yield Comparison

In terms of yield, the only defined information is for Big Devil #2, which is described as offering a good yield for an autoflowering strain. This suggests it is designed to balance speed and productivity so you don’t sacrifice too much harvest weight for the convenience of an auto.

For Big Devil FAST Version, specific yield figures or qualitative yield descriptions are not provided. However, some growers choose fast photoperiod versions because they can extend the vegetative period if desired, potentially allowing more time for plants to develop before inducing flowering. That flexibility can be an advantage for yield-focused growers who are comfortable planning their grow in stages, but it is not guaranteed without more concrete data.

If you are a grower focused on high yield and you want more control over plant size before flowering, the FAST Version’s photoperiod nature might appeal, assuming you are prepared to manage the lighting. If you prefer predictability with less fine-tuning, Big Devil #2’s clearly described “good” yield may be more reassuring.

Effects Comparison

Both strains are described simply as having strong THC. No detailed breakdown of the effect profile is given for either, and both are hybrids, which means their effects are likely to sit somewhere between the typical characteristics of indica- and sativa-leaning plants.

• Big Devil #2 is suited to users who want a clearly potent experience and appreciate a sweet, pungent, skunky aroma alongside that strength.
• Big Devil FAST Version is also targeted at users who prioritise strong THC levels, though flavour and nuanced effect descriptions are not provided.

If your main priority is strong effects, both are designed to deliver potency. In the absence of more detailed effect information, your decision may lean more on cultivation style and flavour preferences than on nuanced differences in the high.

6. Which Should You Choose?

How you decide between Big Devil #2 and Big Devil FAST Version depends primarily on your experience level, how hands-on you want to be, and what you prioritise in the grow.

• Choose Big Devil #2 if:
  • You are a first-time grower or beginner who wants a straightforward, low-management grow.
  • You prefer the simplicity of an autoflowering hybrid that doesn’t require light schedule changes.
  • You want a strain with good yield clearly indicated, without needing to fine-tune every stage.
  • A sweet and pungent, skunky aroma is appealing, and you like the idea of a strong, hybrid-style experience.
• Choose Big Devil FAST Version if:
  • You are comfortable managing a photoperiod grow and planning when to switch to flowering.
  • You want a fast-flowering feminized strain rather than an auto, to keep control over how long plants stay in the vegetative stage.
  • You are a grower looking to balance speed and potential yield by adjusting veg time rather than relying solely on an automatic cycle.
  • Strong THC is a must, and you like the idea of a Big Devil line crossed with a secret strain, even without detailed flavour notes.

For many new growers who are comparing strains before purchase, Big Devil #2 tends to be the safer, easier entry point, while Big Devil FAST Version suits those who are ready to take on a bit more control and complexity in exchange for the flexibility of a feminized photoperiod plant.

7. Final Thoughts

Both Big Devil #2 and Big Devil FAST Version are strong-THC hybrids from Sweet Seeds, built for growers who want noticeable effects and relatively efficient cycles. The key distinction is format: autoflower convenience versus fast photoperiod control.

If you value simplicity and a well-defined “good” yield, Big Devil #2 is a solid pick for a first grow. If you prefer to steer the grow more actively, especially in terms of plant size and veg time, and are comfortable with light management, Big Devil FAST Version offers a faster-than-usual photoperiod option within the same Big Devil family.
