3. 2 Fast 2 Vast Auto Overview

2 Fast 2 Vast Auto from Heavyweight Seeds is a feminized autoflowering hybrid. Its genetics combine Fast and Vast Autoflower with Autoflower Northern Lights, so it is built around automatic flowering and hybrid vigour rather than a specific long-photoperiod lineage.

As an autoflowering strain, 2 Fast 2 Vast Auto does not depend on a strict change in light schedule to start blooming. This generally makes planning easier for new growers: once it is established, it will switch from vegetative growth into flowering on its own, following its internal timing instead of waiting for shorter days.

Because detailed yield data is not provided, you should think of this strain more in terms of convenience and speed than chasing a specific grams-per-plant target. Autoflowering hybrids are often chosen by first-time growers who want a straightforward route from seed to harvest without managing complex light schedules or long grow cycles.

The information available does not specify THC content, flavour profile, or detailed effects for 2 Fast 2 Vast Auto. If you want a strain where the cultivation process and timeline are the main priorities, this still makes sense: the focus here is an easy, automatic hybrid from a known breeder rather than a precisely dialled-in potency or aroma profile.

4. Medi Bomb #2 Overview

Medi Bomb #2 is a feminized hybrid from Bomb Seeds. Unlike the autoflowering option above, Medi Bomb #2 is a photoperiod plant, with a flowering time listed at 9–11 weeks. This means it will need the usual change in light cycle to trigger blooming if grown indoors (typically from a longer to a shorter light period).

Bomb Seeds describe Medi Bomb #2 as having a “good” yield, indicating that, under appropriate conditions, it is bred to produce a solid harvest rather than being a minimal or purely boutique-yield variety. While there is no exact figure given, this label suggests it is a viable choice for growers who care about productivity as well as quality.

In terms of potency, Medi Bomb #2 is noted as “strong” THC. This positions it toward the higher end of intensity, so it is better suited to users who already have some experience with more powerful hybrids or who are specifically looking for a pronounced effect. Exact percentages and detailed effect descriptions are not provided, so it is best approached as a robust, impactful strain rather than a mild option.

No official flavour or aroma information is listed in the available data, so when choosing Medi Bomb #2, your decision should be driven primarily by its strong THC, good yield potential, and more traditional photoperiod structure.

5. Key Differences

General Comparison

The main dividing line between these two seeds is how they grow. 2 Fast 2 Vast Auto is an autoflowering hybrid, while Medi Bomb #2 is a photoperiod hybrid with a 9–11 week flowering phase. Both are feminized, so in each case you are buying seeds bred to produce female plants, which removes most of the work of identifying and removing males.

Breeder choice may also influence your decision. Heavyweight Seeds and Bomb Seeds both specialise in high-performance strains, but they emphasise slightly different things: 2 Fast 2 Vast Auto centres on automatic, straightforward hybrid growing; Medi Bomb #2 is aimed at solid yield and strong THC in a more classic photoperiod format.

Which Is Better for Beginners?

From a cultivation standpoint, beginners often find autoflowering hybrids more forgiving because they simplify the lighting side of the grow. On that basis, 2 Fast 2 Vast Auto can be a practical starting point:

• Autoflowering life cycle: You do not need to time a light schedule change to initiate flowering. The plant transitions when it is ready, which reduces one of the main sources of error for new growers.
• Hybrid genetics: The cross of Fast and Vast Autoflower with Autoflower Northern Lights suggests a plant bred for ease and reliability rather than finicky, high-maintenance traits.

Medi Bomb #2, in contrast, expects the grower to manage a 9–11 week flowering period and the usual photoperiod requirements. That is perfectly manageable for a beginner who is ready to learn about light cycles, but it does add a layer of complexity compared to an autoflower. The reward for handling that complexity is a strain flagged for good yield and strong THC.

So if your main priority is an easy introduction to growing with fewer timing decisions, 2 Fast 2 Vast Auto is likely more beginner-friendly. If you are comfortable following a more traditional schedule or you have some guidance, Medi Bomb #2 is still accessible but slightly more involved.

Yield Comparison

Medi Bomb #2 is the only one of the two with a clear yield indication. It is described simply as having a “good” yield. While this is not a precise quantity, it tells you that Bomb Seeds intend it to be productive enough to satisfy growers who want a decent return from each plant.

Yield data for 2 Fast 2 Vast Auto is not provided, so it should not be chosen purely on promised harvest size. Autoflowering strains can perform well, but they are often selected by first-time growers for their faster life cycle and ease of handling rather than record-breaking output.

If your main priority is maximising harvest and you are willing to manage a 9–11 week flowering period, Medi Bomb #2 has the clearer yield signal. If you are looking for a simpler run and are less concerned about squeezing out every last gram, 2 Fast 2 Vast Auto might still suit you despite the lack of specific yield claims.

Effects Comparison

In terms of effects, the only explicit information provided is for Medi Bomb #2, which is associated with “strong” THC. This indicates a potent experience and makes it attractive to users seeking noticeable, intense effects.

For 2 Fast 2 Vast Auto, there are no official notes on THC level or specific effect characteristics in the available data. Without that, it is best to treat it as a balanced hybrid with unknown exact potency rather than assume it is mild or extremely strong.

• Medi Bomb #2: Clear indication of strong THC, better aligned with users who want powerful, impactful effects.
• 2 Fast 2 Vast Auto: Effects and potency not specified; more of an unknown in this area, so it may appeal to growers who prioritise growth traits and flexibility over precise THC targeting.

If you specifically want a strain with clearly labelled strong potency, Medi Bomb #2 is the more transparent option. If you are more focused on the growing process and less on chasing clearly defined strength, 2 Fast 2 Vast Auto remains a viable choice.

6. Which Should You Choose?

The better option depends on which of the following profiles sounds most like you:

• First-time grower wanting simple cultivation
  If you are new to growing and want to avoid managing photoperiod changes, 2 Fast 2 Vast Auto stands out. Its autoflowering nature streamlines the grow, and the hybrid background from Fast and Vast Autoflower and Autoflower Northern Lights is tuned for practicality. You trade predictable yield and potency figures for a more straightforward experience.
• Beginner or intermediate grower prioritising yield and potency
  If you are comfortable following a typical indoor schedule or growing outdoors where seasons manage the light, and your focus is on a productive harvest with substantial strength, Medi Bomb #2 aligns better. The “good” yield and “strong” THC give you clearer expectations about output and intensity.
• User specifically seeking strong effects
  With Medi Bomb #2 explicitly listed as “strong” in THC, it is the logical pick if pronounced potency is central to your decision. 2 Fast 2 Vast Auto does not carry specific THC data in the available information, so it is less predictable from an effects standpoint.
• Grower balancing convenience with unknowns
  If you value the convenience of an automatic hybrid more than having detailed stats on yield and THC, 2 Fast 2 Vast Auto gives you that simplicity, even if it means accepting less precise information about the final product.

7. Final Thoughts

2 Fast 2 Vast Auto and Medi Bomb #2 both offer feminized hybrid genetics from reputable breeders but aim at slightly different grower needs. The autoflowering structure of 2 Fast 2 Vast Auto makes it attractive to beginners or anyone who wants a low-management grow, while Medi Bomb #2 offers a more traditional 9–11 week flowering schedule with an emphasis on good yield and strong THC.

If you want the most straightforward introduction to cultivation, 2 Fast 2 Vast Auto is likely to feel more approachable. If your priority is a photoperiod hybrid with clearly indicated potency and solid productivity, Medi Bomb #2 will be the more focused choice.
