Big Bang Auto comparisons - Compare with Other Strains
Big Bang Auto is a popular autoflowering cannabis strain that growers often compare with similar varieties based on THC levels, yield potential, flowering time, and overall effects. Use the comparison below to decide whether Big Bang Auto or its photoperiod counterpart is better suited to your growing style and desired experience.
Big Bang Auto vs Big Bang (Greenhouse Seed Co)
When choosing between Big Bang Auto and Big Bang Feminized (photoperiod), it is helpful to understand a few key differences and similarities:
-
Genetics & Growth Type
Big Bang Auto is an autoflowering version, meaning it automatically switches from vegetative growth to flowering without needing a change in the light cycle. Big Bang Feminized is a photoperiod strain, requiring a 12/12 light schedule (12 hours light, 12 hours dark) to trigger flowering. This makes the auto version more beginner-friendly and ideal for growers who want a faster, simpler cycle. -
Flowering Time & Total Cycle
Big Bang Auto generally completes its entire life cycle in about 8–10 weeks from seed to harvest, depending on conditions. In contrast, Big Bang Feminized usually has a flowering time of around 8–9 weeks, but you must also factor in a vegetative phase beforehand. As a result, the feminized photoperiod plant can take slightly longer overall but allows more control over plant size before flowering. -
Yield Potential
Photoperiod strains like Big Bang Feminized typically offer higher yields when grown under optimal conditions, because you can extend the vegetative phase and develop larger plants. Big Bang Auto, while often quicker to finish, may produce moderate to good yields but generally less than the fully matured photoperiod version. Growers who prioritise speed and multiple harvests per season may still prefer the auto. -
THC Levels & Cannabinoid Profile
Both strains are bred by Greenhouse Seed Co and share a similar THC range, often sitting in the medium to high bracket. However, photoperiod varieties like Big Bang Feminized can sometimes express slightly higher cannabinoid and terpene levels due to their longer growth window and greater environmental control. The auto version aims to preserve the same flavour and effect profile in a shorter format. -
Flavour & Aroma
Both Big Bang Auto and Big Bang Feminized usually deliver a sweet, fruity, and slightly earthy aroma, often described as candy-like or floral with a subtle skunky undertone. Any differences in flavour are more likely to come from growing conditions, curing quality, and phenotype variation rather than the auto vs photoperiod nature alone. -
Effects & Usage
The effects of both versions are generally relaxing, calming, and body-focused, often leaning towards a comfortable, soothing experience suitable for evening use. Many users report stress relief and physical relaxation, with a mild to moderate cerebral uplift. Because the genetic base is similar, the overall effect profile tends to be comparable between the auto and photoperiod types. -
Best For
- Big Bang Auto – Best for growers seeking a fast harvest, simpler light schedule, smaller plant size, or discreet indoor/outdoor grows, especially in shorter seasons.
- Big Bang Feminized – Best for growers who want maximum control over plant size and yield, and who are comfortable managing a photoperiod lighting schedule to potentially achieve larger harvests.
