Original Auto Amnesia Haze vs Amnesia Haze: Which Is Best for You?

1. Introduction

Original Auto Amnesia Haze and Amnesia Haze are closely related sativa strains that appeal to similar types of buyers: people who want very strong effects and solid yields. The main difference is how they’re grown. One is an autoflowering version from FastBuds, the other a classic photoperiod feminized line from Royal Queen Seeds.

If you’re a first-time grower, chasing high yields, or simply deciding which Amnesia-style seed suits your grow space and experience level, comparing these two side by side can make the choice much clearer.

3. Original Auto Amnesia Haze Overview

Original Auto Amnesia Haze by FastBuds is an autoflowering take on the Amnesia Haze line, bred from Amnesia Haze Autoflower genetics. As a sativa-type auto with very strong THC, it aims to deliver the kind of powerful experience associated with Amnesia Haze in a more straightforward, time-efficient grow format.

Being an autoflower means this strain does not rely on a change in light cycle to start flowering. Plants move from seedling to harvest automatically under a consistent light schedule. For growers, that typically translates to:

• No need to manage separate vegetative and flowering light schedules.
• A more compact total grow timeline compared with many photoperiod sativas.
• The option to run multiple successive harvests per season in the same space.

The yield is described as good, which is significant for an auto, especially considering its sativa background. Combined with very strong THC levels, this makes Original Auto Amnesia Haze attractive to growers who want robust potency without committing to long flowering times or complex scheduling.

Because the exact flavour, aroma and nuanced effects are not specified, it’s best to think of this strain as a compact, auto-friendly route into the Amnesia Haze family, prioritising ease of cultivation and potency rather than chasing every last gram.

4. Amnesia Haze Overview

Amnesia Haze from Royal Queen Seeds is a feminized, photoperiod version based on classic Amnesia Haze cannabis seeds. It’s a sativa strain known for very strong THC and a reputation as a powerful, long-flowering variety.

As a feminized photoperiod seed, Amnesia Haze requires a controlled light cycle to transition from vegetative growth to flowering. Indoors, this usually means switching from a longer light period to a shorter one to initiate its flowering phase. The flowering time is stated as around 12 weeks, which is lengthy compared with many other strains and especially compared with autos.

The good yield rating reflects what many growers expect from a long-flowering sativa: a potentially rewarding harvest for those prepared to wait and manage the full cycle carefully. With very strong THC, Amnesia Haze is aimed at users who are comfortable with powerful effects and want the full, classic Haze-style experience from a photoperiod plant.

Specific flavour and effect descriptors are not provided, but given the genetics and breeder positioning, this seed is best viewed as a more traditional Amnesia Haze option for growers willing to invest time and attention in the grow.

5. Key Differences

General Comparison

Although both strains share a sativa profile, good yield potential, and very strong THC, they differ fundamentally in how they are grown:

• Original Auto Amnesia Haze is an autoflower that simplifies scheduling and usually shortens the total time from seed to harvest.
• Amnesia Haze is a feminized photoperiod strain with a stated 12-week flowering time, generally resulting in a longer overall grow but with the structure and control some growers prefer.

This core difference influences almost every practical choice: grow-room planning, energy use, number of harvests per year, and how much day-to-day management is required.

Which Is Better for Beginners?

For someone growing for the first time, the main challenge is usually managing the light cycle, timing, and plant size rather than pushing for maximum yield. In that context:

• Original Auto Amnesia Haze can be more beginner-friendly because it flowers automatically. New growers do not need to worry about when to change the light schedule, and the overall cycle tends to be shorter, reducing the window for mistakes.
• Amnesia Haze demands more planning. A 12-week flowering phase requires patience and consistent conditions. The need to manage the switch to flowering can be an extra step that some first-time growers would rather avoid.

Both strains are listed as very strong in THC, so beginners who are new to consumption, as well as cultivation, should be cautious with either option. From a growing perspective alone, the autoflowering FastBuds version is generally more approachable, while the Royal Queen Seeds feminized version suits those ready to handle a full-length photoperiod grow.

Yield Comparison

Both Original Auto Amnesia Haze and Amnesia Haze are rated as offering good yields. That means yield potential is solid on either side, but the path to achieving it differs:

• Autoflower (Original Auto Amnesia Haze): Good yields are notable because autos typically prioritise speed and simplicity. You’re trading some control over plant size and veg time for a quicker, more predictable cycle. For many growers, especially those with limited time or space, this balance of good yields and convenience is ideal.
• Photoperiod (Amnesia Haze): Good yields across a 12-week flowering phase make sense for a classic sativa. The longer flowering period can allow plants to build more mass, provided you maintain good conditions throughout. For growers who can manage the full timeline, the good yield rating suggests a harvest that rewards the wait.

If you measure yield per year rather than per crop, autoflowers like Original Auto Amnesia Haze may allow multiple runs in the time it takes to complete one long Amnesia Haze cycle, potentially balancing out or even surpassing single-cycle yield advantages of the photoperiod in some setups.

Effects Comparison

Both strains are described simply as having very strong THC and a sativa type, with no detailed effect breakdown. That limits direct, precise comparison, but a few general points can still guide your choice:

• Original Auto Amnesia Haze: Expect a potent sativa-style experience consistent with very strong THC. As an autoflower based on Amnesia Haze genetics, it is likely chosen by users who prioritise intensity and want that in a more accessible grow format.
• Amnesia Haze: Built on classic Amnesia Haze cannabis seeds and also rated very strong in THC, this is aimed at users seeking a powerful, traditional Amnesia Haze experience from a full photoperiod plant.

Because both are in the same potency range, the choice from an effects perspective is less about strength and more about how closely you want to follow the traditional Amnesia Haze growing style versus opting for an autoflowering interpretation.

6. Which Should You Choose?

The better option depends on your priorities: ease of cultivation, time frame, and how involved you want to be in managing the grow.

• Choose Original Auto Amnesia Haze if:
  • You are a first-time grower and want to avoid managing light-cycle changes.
  • You prefer a faster, more straightforward route from seed to harvest.
  • You still want very strong THC and good yields but value simplicity and shorter cycles.
  • You aim to run multiple harvests per year in a compact space.
• Choose Amnesia Haze if:
  • You are comfortable managing a 12-week flowering phase and the associated light schedule.
  • You want a more traditional, photoperiod Amnesia Haze growing experience.
  • You’re prepared to invest time and attention in exchange for good yields from a classic sativa line.
  • You already have some growing experience or are willing to take on a more demanding first project.

For users mainly focused on strong effects, both options deliver very strong THC. In that case, your decision is best made on grow style and time commitment rather than on potency alone.

7. Final Thoughts

Original Auto Amnesia Haze and Amnesia Haze sit on the same genetic family tree but cater to different growers. The FastBuds autoflower version offers a practical, time-efficient way for beginners and busy growers to enjoy a potent sativa harvest with good yields. The Royal Queen Seeds feminized version, on the other hand, appeals to those who want the full-length, classic Amnesia Haze experience and are ready to manage a longer 12-week flowering period.

If simplicity and speed matter most, Original Auto Amnesia Haze is likely the better fit. If you’re aiming for a traditional photoperiod project and don’t mind the wait, Amnesia Haze remains a solid choice in the classic sativa category.
