Arjans Haze vs Arjans Haze #2: Which Feminized Sativa Should You Grow?

1. Introduction

Arjans Haze and Arjans Haze #2 are both well-known sativa-dominant cannabis seeds from Greenhouse Seed Co. If you are choosing between these two feminized strains, you are likely interested in strong, uplifting effects and a classic Haze-style experience. However, there are important differences in genetics, flowering time and overall suitability for beginners that can help you decide which one fits your goals better.

This comparison focuses on practical questions growers actually have: which is more beginner-friendly, how the flowering times compare, what to expect in terms of effects strength, and which might be better if you are chasing higher yields or a specific growing style.

3. Arjans Haze Overview

Arjans Haze is a feminized sativa from Greenhouse Seed Co, created by combining G13 with a classic Haze. This genetic mix places it in the category of powerful, long-flowering sativas that appeal to experienced users and growers looking for intensity rather than speed.

The breeder lists Arjans Haze with an 11-week flowering time. For indoor growers, this means planning for a cycle that runs longer than many indica-leaning hybrids. Outdoor growers in suitable climates will need a season long enough to let the plants fully mature. This extended flowering period is typical of many Haze-based strains and often comes with a more demanding grow, especially for first-timers who are not yet used to managing tall, vigorous sativas.

In terms of potency, Arjans Haze is described as having very strong THC. That makes it a candidate for users seeking a pronounced, intense effect rather than something mild. For growers, this high THC potential is usually one of the main reasons to select Arjans Haze over milder varieties, provided they are comfortable handling a powerful strain.

Because it is feminized, you can expect the seeds to produce female plants, reducing the need to identify and remove males. This is helpful for new growers, but the long flowering window and strong effect profile still make Arjans Haze more suitable for those ready to manage a more demanding sativa.

4. Arjans Haze #2 Overview

Arjans Haze #2 is another feminized sativa from Greenhouse Seed Co, built from Haze and Lao genetics. While it shares the general sativa character with the original Arjans Haze, the genetic base is different, which can translate into variations in structure, flowering behaviour and the type of high or uplift it delivers.

The stated flowering time for Arjans Haze #2 is 10 weeks, which is notably shorter than Arjans Haze. That one-week difference may sound small, but it can be important in practice: harvesting earlier can reduce the total time your grow room is occupied, and outdoor growers in areas with a shorter season may find the slightly quicker finish more manageable.

No specific THC level is given for Arjans Haze #2, so you do not have the same clear “very strong” label that the original Arjans Haze carries. It is still a Haze-based sativa, so it is reasonable to expect an active, uplifting profile, but without explicit potency data, it is best not to assume it will be as intense as Arjans Haze. For some users, that uncertainty can actually be a positive if they prefer not to commit to the highest strength option.

Like Arjans Haze, Arjans Haze #2 comes as feminized seed, simplifying plant selection and allowing you to focus on training, nutrition and environment instead of sexing plants. Combined with the shorter flowering period, this makes it a realistic candidate for growers who want a Haze experience but are cautious about very long flowering times.

5. Key Differences

General Comparison

Both strains are feminized sativas from the same breeder, but they diverge in genetics and cycle length. Arjans Haze pairs G13 with Haze, while Arjans Haze #2 blends Haze with Lao. These different backgrounds can influence plant structure, vigour and how they respond to training, even though both will express sativa traits.

Arjans Haze is positioned more clearly as a “very strong” THC option, while Arjans Haze #2 does not come with a defined THC description. If you want a strain with clearly identified high potency, the original Arjans Haze offers more certainty. If you prefer a Haze without a specified “very strong” THC label, Arjans Haze #2 may feel like a more balanced or less intimidating choice.

Which Is Better for Beginners?

For someone attempting their first grow, there are two main considerations: how long the strain takes to finish and how demanding its sativa traits may be.

• Arjans Haze (11 weeks): The longer flowering period means more time managing tall plants, more exposure to potential issues late in flower, and a longer wait before harvest. Combined with its very strong THC description, this option is typically more suited to growers and users who already know they want a powerful, extended sativa run.
• Arjans Haze #2 (10 weeks): The 10-week flowering time is still not “short,” but it is more forgiving than 11 weeks. Even a single week less can simplify scheduling, reduce the total time you need to maintain ideal conditions, and may feel more manageable for a first-timer.

Neither strain is a classic “fast and easy” beginner indica, but between the two, Arjans Haze #2 is generally the more beginner-appropriate choice due to its shorter flowering window and the absence of an explicit “very strong” THC label. New growers who still want a Haze experience may find Arjans Haze #2 a slightly more accessible starting point.

Yield Comparison

The product data provided does not specify yields for either Arjans Haze or Arjans Haze #2. Without explicit yield figures, it is not possible to say definitively which one produces more per plant or per square metre.

However, a few general points can still guide yield-focused growers:

• Both are sativas, which typically have the potential for good yields when given enough space, light and time, but they may require more training and management than compact indica-dominant strains.
• Arjans Haze’s 11-week flowering time suggests it may stay in bloom longer, which can sometimes correlate with more biomass if the plant is healthy and well-fed throughout the cycle.
• Arjans Haze #2, finishing in around 10 weeks, may allow for slightly faster turnover or better timing in climates where the season is limited.

If your primary concern is absolute yield, you will likely want to look beyond flowering time and consider grow logs, breeder notes or community reports. Based solely on the provided information, neither strain can be clearly called the higher yielder, so your training method, environment and plant health will play a major role in the final result.

Effects Comparison

Specific detailed effects are not listed for either strain, but the available data does give one crucial distinction:

• Arjans Haze: Described as having very strong THC. For users, this indicates an especially potent experience, which may be more intense and long-lasting than moderate-strength varieties. Those already accustomed to strong sativas may seek out this kind of profile.
• Arjans Haze #2: No defined THC description is provided. While it is still a Haze-based sativa and likely uplifting, the absence of a “very strong” THC note suggests it is not specifically highlighted for maximum potency in the same way as Arjans Haze.

For users looking specifically for strong effects, Arjans Haze is the clearer pick based on the available data. Those who prefer a sativa experience without explicitly targeting the highest potency may be more comfortable with Arjans Haze #2.

6. Which Should You Choose?

Your choice between Arjans Haze and Arjans Haze #2 should come down to experience level, desired potency and how much time and effort you are willing to invest in the grow.

• Choose Arjans Haze if:
  • You want a sativa with clearly defined very strong THC.
  • You are comfortable managing an 11-week flowering cycle.
  • You are an experienced user or grower looking for an intense effect and do not mind the longer wait.
• Choose Arjans Haze #2 if:
  • You are a first-time or relatively new grower who still wants a Haze-style sativa.
  • You prefer a slightly shorter flowering time (around 10 weeks).
  • You do not need the maximum advertised potency and are comfortable with a Haze that does not have a specific THC strength label.

For a beginner looking for easier cultivation within the Haze family, Arjans Haze #2 is generally the more practical route. For a user focused on the strongest effects and willing to handle a longer and potentially more demanding cycle, Arjans Haze stands out.

7. Final Thoughts

Both Arjans Haze and Arjans Haze #2 offer a sativa-forward experience from a well-known breeder, but they are not identical options. Arjans Haze leans toward maximum potency and a longer 11-week flowering time, making it more appealing to seasoned growers and users who actively seek strong effects. Arjans Haze #2, with its 10-week flowering period and undefined THC strength, provides a slightly more accessible entry point into Haze cultivation, especially for newer growers or those who prefer a somewhat less imposing profile on paper.

If you prioritise ease of cultivation and a more manageable schedule, Arjans Haze #2 is likely the better fit. If your main goal is a very strong THC sativa and you are prepared for a longer grow, Arjans Haze is the more targeted choice.
