3. 2 Fast 2 Vast Auto Overview

2 Fast 2 Vast Auto is a feminized hybrid from Heavyweight Seeds, built from Fast and Vast autoflower crossed with autoflower Northern Lights. As a fully autoflowering strain, it begins flowering automatically after a short vegetative phase rather than depending on a strict light schedule. This makes it particularly attractive to new growers or those with simple indoor setups.

The Northern Lights autoflower heritage suggests a focus on stability and manageable growth patterns, which is often appreciated by beginners. While exact yield, flavour and effect details are not provided, the hybrid nature and autoflower genetics typically point toward a balanced profile and a relatively compact life cycle compared with many photoperiod strains.

Because 2 Fast 2 Vast Auto is feminized, growers can expect female plants from their seeds, which reduces the need to identify and remove males. Combined with the autoflowering trait, this simplifies cultivation: you can often keep a consistent light schedule from start to finish, and the plant will handle the transition to flowering on its own.

For first‑time growers or anyone who wants an uncomplicated grow without fine‑tuning light cycles, these characteristics make 2 Fast 2 Vast Auto a practical choice, especially where space, time, or experience are limited.

4. Medi Bomb #2 Overview

Medi Bomb #2 is a feminized hybrid from Bomb Seeds, designed with a “good” yield and “strong” THC. While its exact genetic breakdown and flavour profile are not specified, it is clearly positioned as a potent option for users who prioritise strong effects from their harvest.

Unlike an autoflower, Medi Bomb #2 follows a traditional photoperiod pattern, with a flowering time of around 9–11 weeks. This means the grower typically controls when flowering begins by adjusting the light schedule (indoors), or it will start to flower naturally as outdoor daylight hours shorten.

The described “good” yield makes Medi Bomb #2 appealing if you want to balance potency with reasonable productivity. The “strong” THC note indicates that its effects may be intense and best suited to users who are either experienced with cannabis or specifically looking for powerful effects from their buds.

As a feminized hybrid, Medi Bomb #2 also removes the hassle of sorting male plants, but it does require a bit more planning and patience than an autoflower strain. Managing the 9–11 week flowering phase and any vegetative time before that makes this strain better suited to growers who are comfortable with photoperiod timing or are ready to learn.

5. Key Differences

General Comparison

At a high level, the main distinction is how these strains grow and what they offer at harvest:

• 2 Fast 2 Vast Auto is an autoflowering, feminized hybrid with Northern Lights autoflower in its lineage. It emphasises ease of cultivation and a straightforward life cycle over tightly defined flowering times or quantified yields.
• Medi Bomb #2 is a feminized, photoperiod hybrid with a defined 9–11 week flowering window, a “good” yield and “strong” THC, making it more focused on potency and productive harvests.

If you want a hands‑on growing experience and are comfortable controlling the light schedule, Medi Bomb #2 offers more specific data around flowering time, yield, and strength. If you prefer a set‑and‑forget style grow with fewer variables, 2 Fast 2 Vast Auto’s autoflower trait is the key advantage.

Which Is Better for Beginners?

For first‑time growers, ease of cultivation is usually more important than fine‑tuning yield or potency. Here the grow styles differ significantly:

• 2 Fast 2 Vast Auto:
  • Autoflowering, so it does not rely on a specific light cycle to start flowering.
  • Reduces the need to manage separate vegetative and flowering periods.
  • Feminized seeds minimise the risk of unwanted male plants.
• Medi Bomb #2:
  • Photoperiod hybrid, typically requiring a change in light schedule to induce flowering indoors.
  • Longer, defined flowering time (9–11 weeks) that needs planning and patience.
  • Also feminized, but more sensitive to cultivation decisions like when to flip to flower.

For someone completely new to growing, 2 Fast 2 Vast Auto is generally the more beginner‑friendly option because autoflowers reduce complexity around timing and lighting. Medi Bomb #2 can certainly be grown by a motivated beginner, but it rewards growers who are willing to learn photoperiod management and wait out the full flowering period.

Yield Comparison

Only Medi Bomb #2 comes with explicit yield information, described as offering a “good” yield. This tells you that the breeder expects solid production under suitable conditions, pairing well with its strong THC.

For 2 Fast 2 Vast Auto, there is no specific yield figure given. Autoflowering strains in general can be more compact and faster, but yield can vary widely based on environment, grower skill, and phenotype. Without numbers, it’s safer to see 2 Fast 2 Vast Auto as the more convenience‑oriented option rather than a purely yield‑driven choice.

If your main goal is to maximise harvest size and you can handle a longer, more controlled grow, Medi Bomb #2 has the clearer yield promise. If you’re willing to accept less predictable yields in exchange for simplicity and a shorter overall cycle, 2 Fast 2 Vast Auto has the edge.

Effects Comparison

Medi Bomb #2 is explicitly described as having “strong” THC. While the exact percentage is not listed, this indicates the breeder expects potent effects, likely suited to users who want intense experiences or who already have some tolerance.

For 2 Fast 2 Vast Auto, specific effects or THC levels are not provided. Its hybrid status and Northern Lights autoflower background suggest a balanced direction, but without measured data, it’s more accurate to say its effects are not defined in the available information.

This means the choice on effects is straightforward:

• Choose Medi Bomb #2 if you are clearly seeking strong, impactful effects and don’t mind a longer flowering schedule.
• Choose 2 Fast 2 Vast Auto if you prioritise ease of growing over having precisely quantified potency, or if you prefer to discover the effect profile yourself as you go.

6. Which Should You Choose?

Your ideal strain depends on what matters most: simplicity, yield, or strength of effects. Here are some common situations and how each strain fits.

• First‑time grower with basic equipment
  2 Fast 2 Vast Auto is generally the safer choice. The autoflowering trait removes the need to manage lighting schedules, and feminized seeds cut down on surprises. It suits small spaces and growers who want a straightforward start.
• User looking for strong effects
  Medi Bomb #2 stands out because it is clearly described as having “strong” THC. If intensity is a priority and you can invest more time into the grow, this strain aligns better with your goals.
• Beginner looking for easy cultivation but curious about potency
  If ease is your top concern, lean toward 2 Fast 2 Vast Auto. If you’re willing to take on a steeper learning curve for a more defined strong THC outcome, Medi Bomb #2 is the more targeted pick.
• Grower focused on high yield
  Medi Bomb #2 explicitly promises a “good” yield. While not a precise figure, it indicates a focus on decent production. 2 Fast 2 Vast Auto doesn’t include yield data, so if the size of your harvest is critical, Medi Bomb #2 is the more data‑backed option.
• Short, simple grow with fewer variables
  2 Fast 2 Vast Auto, being an autoflower, keeps things compact and less dependent on schedule changes, making it suitable for quick, low‑maintenance runs.

7. Final Thoughts

Both 2 Fast 2 Vast Auto and Medi Bomb #2 are feminized hybrids, but they serve different needs. 2 Fast 2 Vast Auto is the more beginner‑oriented, convenience‑driven option thanks to its autoflowering genetics and straightforward cultivation. Medi Bomb #2, with its 9–11 week flowering time, good yield and strong THC, is better suited to growers willing to manage a full photoperiod cycle in pursuit of potent, productive results.

If you value an easy first grow, choose 2 Fast 2 Vast Auto. If you prioritise a good harvest and strong effects and you’re ready to handle a more involved grow, Medi Bomb #2 is the more focused choice.
