3. Big Devil FAST Version Overview

Big Devil FAST Version is a feminized hybrid from Sweet Seeds, developed by crossing Big Devil Auto with a mystery photoperiod strain. This background suggests Sweet Seeds aimed to combine the speedy characteristics of an autoflower with traits from a non-auto partner, while keeping the plant photoperiod-dependent and fast to finish. Although the exact flowering time and yield are not specified, it sits in the “fast version” category, typically chosen by growers who want shorter cycles than standard photoperiods.

As a hybrid with strong THC, Big Devil FAST Version is positioned for users seeking pronounced potency rather than a mild experience. Without specific effect notes, you can expect a generally powerful hybrid impact rather than something ultra-light or purely subtle. The feminized nature of the seeds means you avoid dealing with male plants, which simplifies planning and makes better use of your grow space.

Because the strain’s detailed grow guidance and yield figures are not listed, Big Devil FAST Version may appeal more to growers who are comfortable working with limited upfront data—those who like to experiment and fine-tune their own approach rather than relying on strict guidelines.

4. Candy Kush Fast Version Overview

Candy Kush Fast Version is a feminized hybrid produced by Royal Queen Seeds. It brings together Sweet Special and Royal Kush, combining sweet-leaning genetics with classic Kush influence. This strain has a clearly stated flowering time of around 7 weeks, which is relatively quick for a photoperiod hybrid and a key advantage for growers who want a faster turnover or operate in regions with shorter outdoor seasons.

Candy Kush Fast Version is described as having a “good” yield, providing at least some guidance on productivity compared to strains with no yield information at all. As with Big Devil FAST Version, its THC level is classified as strong, placing it in the higher-potency category suited to users looking for more intense effects.

Because its genetic background and flowering time are clearly defined, Candy Kush Fast Version can be easier to plan around. Growers can schedule their cycles, estimate harvest windows, and match the 7-week flowering period to their available time and environment with more confidence.

5. Key Differences

General Comparison

On the surface, both strains are feminized, fast-finishing hybrids with strong THC, but their differences lie in breeding approach and the level of available information:

Breeder and background: Big Devil FAST Version comes from Sweet Seeds and uses Big Devil Auto crossed with an undisclosed strain. Candy Kush Fast Version comes from Royal Queen Seeds, with clearly stated parents (Sweet Special x Royal Kush).
Transparency: Candy Kush Fast Version has specific details for flowering time and a general yield rating, while Big Devil FAST Version lacks this information in the available data.
Planning your grow: With Candy Kush Fast Version’s 7‑week flowering time, you can plan harvest dates more precisely. Big Devil FAST Version is known as a “fast” option, but without an exact number of weeks listed here, planning involves more estimation.

Which Is Better for Beginners?

For first-time growers, the clarity of available information can be as important as the strain itself.

Candy Kush Fast Version is likely more beginner-friendly from a planning perspective because it provides a clear 7-week flowering time and indicates a good yield. This helps new growers schedule their feeding, flushing, and harvest more confidently.
Big Devil FAST Version may still be accessible to beginners, but the lack of specified flowering time and yield in the provided data means you will rely more on observation and general fast-version guidelines. Growers who are completely new might find this less straightforward.

Both strains are feminized, which is a plus for beginners, as there is no need to identify and remove males. However, if you want more structure and predictability, Candy Kush Fast Version has a slight edge for new growers simply because you have more concrete reference points.

Yield Comparison

Yield is a major deciding factor for many growers, especially those with limited space who want to maximise their harvest from each run.

Candy Kush Fast Version is described as having a “good” yield. While this is not a precise figure, it still signals that the strain is expected to perform at a solid level under typical conditions. For yield-focused growers, having that assurance can be useful when choosing between similar strains.
Big Devil FAST Version does not have yield data listed in the provided information. It may still produce well, but from this data alone, you do not have a benchmark to compare against other varieties. If your main priority is guaranteed productivity and you rely heavily on stated yield guidance, this absence may be a drawback.

If yield is your main concern and you want at least some indication of performance, Candy Kush Fast Version is the safer, more predictable option based on the available information.

Effects Comparison

Both Big Devil FAST Version and Candy Kush Fast Version are hybrids with strong THC, putting them in a similar potency bracket. This makes them appealing to users looking for more intense effects rather than gentle, low-THC experiences.

However, the data provided does not include specific effect profiles (such as whether they lean more towards physical or mental impact, or how long they typically last). Because of that, any detailed comparison of their effects would be speculative and is not supported by the available information.

From what we do know:

Both are hybrid strains with strong THC, so in either case you should be prepared for pronounced effects rather than mild ones.
If you are entirely new to consuming strong strains, it can be sensible to approach either option with care, starting with small amounts and seeing how you respond.

For a user simply looking for “strong effects,” either strain will fit that requirement on paper, as both are categorised as potent hybrids.

6. Which Should You Choose?

Your choice between Big Devil FAST Version and Candy Kush Fast Version should come down to how much structure you want in your grow and which aspects you are prioritising.

Choose Big Devil FAST Version if:
- You are interested in Sweet Seeds’ Big Devil line and want a fast hybrid derived from Big Devil Auto.
- You do not mind working with less detailed data on flowering time and yield, and you are comfortable adjusting as you go.
- You like experimenting with strains where the full genetic picture (including the mystery cross) is not completely revealed but still backed by an established breeder.
Choose Candy Kush Fast Version if:
- You want a clearly defined flowering time of about 7 weeks, making scheduling easier, especially for a first grow.
- You value having at least a general indication of yield (“good”) when planning your run and setting expectations.
- You prefer transparent genetics (Sweet Special x Royal Kush) and want a dependable fast hybrid from Royal Queen Seeds.
- You are a beginner or cautious grower who relies on stated breeder data to guide your decisions.

If you are entirely new to cultivation and unsure where to start, the more detailed information available for Candy Kush Fast Version makes it the more straightforward choice. Growers who already have some experience or are specifically attracted to Sweet Seeds’ catalogue might find Big Devil FAST Version an interesting alternative to explore.

7. Final Thoughts

Both Big Devil FAST Version and Candy Kush Fast Version deliver what many growers look for: feminized, fast-finishing hybrid seeds with strong THC potential. The key difference is not so much in raw power as in how much guidance you get from the outset. Candy Kush Fast Version stands out for beginners and yield-focused growers thanks to its 7-week flowering time and good yield rating, while Big Devil FAST Version appeals to those comfortable with a bit more uncertainty who are drawn to Sweet Seeds’ Big Devil genetics.

By weighing your need for structure, your experience level, and how important clear yield and timing data are to you, you can choose the strain that best fits your grow and your preferences as a consumer.
