3. Old White Widow Overview (z710 Genetics)

Old White Widow from z710 Genetics is a feminized hybrid derived from a cross of White Widow with itself. This reinforces the core White Widow character while allowing the breeder to refine certain traits. Both the genetic background and the strong THC description point towards a potent, classic hybrid experience, which can appeal to users looking for noticeable, robust effects.

In terms of cultivation, Old White Widow has a flowering time of 8–9 weeks. This fits comfortably into a standard indoor cycle and gives outdoor or greenhouse growers a predictable harvest window. Its yield is described as “average,” which suggests a balanced focus: you are not trading everything for maximum production, nor sacrificing quality for minimal return. Instead, it sits in the middle, suitable for growers who value reliability and consistency over pushing for the heaviest possible harvest.

One standout detail is the “delicious and zesty” flavour and aroma profile. While the exact notes are not specified, this indicates a more pronounced and lively taste than a completely neutral or earthy strain. If you pay attention to how a strain smells and tastes when consumed, this can be a deciding factor, especially if you prefer something with a bright, zesty edge.

Because these are feminized seeds, you can expect them to produce female plants, which simplifies cultivation. This is especially helpful for beginners who want to avoid dealing with male plants or accidental pollination. Combined with the moderate flowering time and average yield, Old White Widow works well as a steady, predictable option rather than a high-risk, high-reward choice.

4. White Widow Overview (Bulldog Seeds)

White Widow by Bulldog Seeds is another feminized hybrid, but with clearly stated Brazilian and South Indian origins. This points to a more geographically diverse background than Old White Widow’s White Widow × White Widow cross, which may interest growers who value established, traditional lineages when selecting seeds.

Like Old White Widow, Bulldog’s White Widow finishes flowering in about 8–9 weeks. For scheduling, this means both strains can be run in similar grow room rotations without major changes to your lighting or planning. Where Bulldog’s White Widow begins to stand apart is yield: it is listed as providing a “good” yield. While this is still a general description rather than a precise figure, it hints at a potential advantage in production over the “average” output of Old White Widow.

The THC level is also described as strong, placing this version of White Widow firmly in the potent category. This makes it suitable for users seeking intense effects rather than something gentle or subtle. Although the exact flavour and aroma are not specified, many growers choose Bulldog Seeds strains for their consistency and solid performance, and this White Widow fits that role as a dependable, strong hybrid in the garden.

With feminized seeds and a straightforward flowering window, Bulldog’s White Widow is positioned as an accessible option. The combination of strong THC and good yield makes it appealing for growers who want to maximise both impact and production in a single run.

5. Key Differences

General Comparison

On the surface, Old White Widow and White Widow look very similar: both feminized, both hybrids, and both finishing in 8–9 weeks with strong THC. The main distinctions lie in their genetics, yield expectations, and the flavour information provided.

• Genetics: Old White Widow refines the White Widow line by crossing it back into itself, keeping the lineage very tight. Bulldog’s White Widow instead highlights broader Brazilian and South Indian roots, reflecting a more traditional White Widow background.
• Yield: Old White Widow is described as “average” yield, while Bulldog’s White Widow is rated at a “good” yield, suggesting that growers focused on quantity may lean toward the Bulldog version.
• Flavour/Aroma: Old White Widow is specifically noted as “delicious and zesty,” while Bulldog’s White Widow has no flavour notes listed. If taste and aroma matter to you, Old White Widow offers clearer expectations on that front.

Which Is Better for Beginners?

Both strains are beginner-friendly in several ways: they are feminized, share a manageable 8–9 week flowering period, and come from established breeders. For a first-time grower, the main question becomes: which one makes the learning curve smoother and more rewarding?

• Ease of planning: Either strain will fit easily into a standard indoor schedule, so there is no advantage to one or the other in terms of timing.
• Predictability: Old White Widow’s average yield and self-crossed White Widow genetics may appeal to beginners who want a balanced, steady result without chasing extreme output. It offers a clear profile with a described flavour and strong THC, giving you a good idea of what you are working towards.
• Beginner motivation: Bulldog’s White Widow, with its “good” yield, could be more rewarding for a first grower who wants to see a bit more in the jars at the end of harvest, as long as they are prepared to manage a potentially slightly more productive plant.

In short, both are suitable for beginners, but Old White Widow aligns with growers who prefer a measured, balanced first run, while Bulldog’s White Widow may better suit a novice who is already aiming for a more productive harvest.

Yield Comparison

Yield is one of the clearest differentiators between these two strains based on the available data:

• Old White Widow (z710 Genetics): Rated as “average” yield. This suggests moderate production without special emphasis on heavy cropping. It can suit personal growers who prioritise consistency over volume.
• White Widow (Bulldog Seeds): Listed as having a “good” yield, implying stronger production potential under similar conditions. For growers focused on maximising output per run, this may be the more attractive choice.

Because both strains share the same flowering length, the difference is not about time invested but about how much you are likely to harvest in that 8–9 week window. If your main goal is a heavier harvest from a strong hybrid, Bulldog’s White Widow has the clearer yield advantage based on the data given.

Effects Comparison

Both Old White Widow and Bulldog’s White Widow are described as having strong THC and are hybrid in type. While detailed effect profiles are not provided, a few general points can still guide your decision:

• Potency: Each strain is noted as “strong” in THC, so neither is positioned as mild. Users looking for pronounced effects rather than gentle impact will be well served by either option.
• Balance: As hybrids, both are likely to offer a mix of characteristics rather than being described as purely uplifting or purely heavy. Without specific effect notes, there is no clear advantage for one over the other in terms of the nature of the high; they occupy a similar space on paper.
• Consistency of experience: Old White Widow’s tight White Widow × White Widow cross may appeal if you want to stay as close as possible to a focused White Widow experience. Bulldog’s White Widow, drawing from Brazilian and South Indian origins, represents another take on the same family, with its own breeder-specific interpretation.

For a user specifically chasing strong effects, the main takeaway is that both strains meet that requirement; your choice may instead come down to yield and flavour rather than potency differences.

6. Which Should You Choose?

To decide between Old White Widow and White Widow by Bulldog Seeds, it helps to match each strain to a specific type of grower and consumer.

• Choose Old White Widow if:
  • You want a straightforward hybrid with a clear White Widow × White Widow background.
  • A “delicious and zesty” flavour and aroma is important in your selection.
  • You are comfortable with an average yield in exchange for a balanced, predictable grow.
  • You are a beginner who values simplicity, feminized seeds, and a standard 8–9 week flowering schedule without focusing heavily on maximum output.
• Choose Bulldog’s White Widow if:
  • Your priority is getting a “good” yield within the same 8–9 week timeframe.
  • You are primarily focused on strong THC and production rather than flavour details.
  • You appreciate the Brazilian and South Indian origins associated with a classic White Widow background.
  • You are a yield-focused grower, even as a beginner, and want a strain that is described as more productive.

For a first-time grower who wants a balanced introduction to growing without chasing maximum output, Old White Widow can be a comfortable starting point. For a grower, beginner or otherwise, who wants strong hybrid effects and a bit more emphasis on harvest size, Bulldog’s White Widow may be the more suitable option.

7. Final Thoughts

Old White Widow and Bulldog’s White Widow sit very close to each other in flowering time, THC strength, and general hybrid profile. The main decision points come down to yield and flavour: Old White Widow offers an average-yielding but zesty, clearly characterised White Widow cross, while Bulldog’s White Widow emphasises a good yield from a strong, established hybrid line.

If you are weighing these two strains before buying seeds, consider how much you value flavour details versus harvest volume. Match that to your experience level and growing goals, and either of these feminized White Widow options can be a solid choice for a strong, reliable hybrid run.
