Green Crack is a potent sativa-dominant strain famous for its energizing effects and hefty yields. A major advantage is its super fast 8-9 week flowering time, though its pungent aroma is strong during this phase.

It's a relatively easy strain to grow, especially with feminized seeds. Indoors it hits a manageable max height around 200cm thanks to some indica genetics. Outdoors in ideal conditions it can tower up to 3.5 meters tall.

This versatile plant thrives indoors, outdoors, and in greenhouses. Yields are enormous at 500-600g/m2 inside and up to 1200g/plant outside. With THC levels of 25%, Green Crack delivers both high quantity and quality.

The speedy flowering and massive yields make Green Crack a coveted strain among growers.

3. Amnesia Haze (60-65 days)

Amnesia Haze is a wildly popular, award-winning sativa cherished for its massive yields, energizing high, and distinct lemon aroma. A major perk is its relatively short 9 week flowering time for a haze.

Yields are insane at up to 650g/m2 indoors and a whopping 800g/plant outdoors. THC hits 20%, earning it a spot among high THC strains. The zesty lemon scent and peppery, citrusy flavor make for an uplifting experience.

Plants grow 80-140cm indoors but can reach 2.5m outside. While its origins are unknown, Amnesia is a cross of Thai, Hawaiian, and Afghani strains. The euphoric, stimulating effects have earned it numerous Cannabis Cups and worldwide fame.

Plants reach 90-130cm indoors and yield a hefty 500-600g/m2. Outdoors they can stretch to 130-180cm tall and produce even bigger at 600-700g per plant.

Despite the sativa genetics, Jack Herer isn't too difficult to tame indoors with some training. It is nutrient hungry though, so feed it well for optimal results. Cold climates may benefit from a greenhouse.

Jack Herer also stays low odor until after harvest, keeping gardens discreet. With its speedy grow time, high yields, and multifaceted effects, it's easy to see why Jack Herer is so widely beloved.

5. Sour Diesel (63-70 days)

Sour Diesel is renowned for its potent, resinous buds and intensely uplifting high. A major advantage is its relatively quick flowering time of just over 10 weeks, allowing growers to harvest wonderful buds soon after planting.

It has excellent yield potential, with outdoor plants producing up to 600g each and indoor yields of 500g/m2. Outdoor growing in the Northern Hemisphere will be ready for harvest in early October.

Plants can grow quite tall, 120-160cm indoors and 160-300cm outside. Despite moderate 20% THC, Sour Diesel can be potent, especially for new users. It has a unique diesel fuel aroma with lemony, earthy flavors.

While the smell is intense at first, it's surprisingly pleasant, citrusy and soft. The fast flowering time and stellar yields make Sour Diesel a coveted strain for growers.

Super Silver Haze is an award-winning legend known for its stellar genetics, high 21% THC, and therapeutic perks. Despite being sativa-dominant, it flowers quickly in just 9-10 weeks.

You can anticipate bountiful yields - up to 600g/m2 indoors and 700g/plant outside. Beginners may find it challenging due to its space requirements. Feminized or autoflowering seeds can simplify things.

Plants reach 120-160cm indoors and 220cm outside with pale green leaves and silvery buds when flowering. It needs ample room to thrive indoors or out but rewards growers with massive yields in both settings.

The uplifting, focused high boosts mood and creativity without causing couch-lock. It has a smooth, lemony aroma and sweet, earthy taste. New users should go slow with Super Silver Haze due to the intense THC levels.

7. Durban Poison (63-72 days)

Durban Poison is a top sativa for new and veteran growers since it thrives anywhere and is easy to cultivate. This resilient strain flourishes in diverse climates and resists fungi.

It flowers fast in 9-10 weeks and delivers generous yields - around 400-450g/m2 indoors and 500-700g per plant outdoors. The moderately potent 15% THC provides an energetic, balanced high perfect for creativity and socializing.

With its complex citrus-pine-spice profile, Durban Poison is an enjoyable, unfussy strain that produces abundant harvests quickly.

8. Maui Waui (63-77 days)

Maui Waui, a Hawaiian Sativa, quickly blooms in 9-11 weeks, perfect for fast harvests in October or April, depending on your hemisphere.

It's an easy-grower, resistant to mold, with generous yields – up to 450g/m² indoors and 900g per plant outdoors. Despite its tall stature (up to 175cm outdoors), methods like SCROG or SOG can keep it manageable.

Great for daytime, Maui Waui hits with a happy, energetic buzz, thanks to its 19% THC level. It's ideal for regular users; newbies should tread lightly. The high starts vibrant and eases into a relaxed state, keeping you uplifted throughout.

Taste-wise, it's a tropical treat, blending fruity, herbal notes with a hint of pineapple and citrus.

9. Super Lemon Haze (65-70 days)

Super Lemon Haze is a popular sativa-dominant hybrid crossing Super Silver Haze and Lemon Skunk. It offers an energizing, euphoric high and delightful lemon scent, but has a longer 10 week flowering time.

With patience, you'll be rewarded with sublime yields. It flourishes indoors or outdoors in warm climates like California. Plants can grow quite tall thanks to the sativa genetics, reaching 1-1.5m indoors and up to 2m outside.

Experienced growers can maximize yields indoors and out using organic soil, hydroponics, ScrOG, and LST techniques. Since these are feminized seeds, plants will be female which prevents pollination and reduced yields.

You can anticipate up to 700g/m2 indoors and 900g/plant outdoors if grown well. While flowering runs longer, Super Lemon Haze is worth the wait for its soaring sativa high and heavy lemon yields.

10. Chocolope (70-75 days)

Chocolope, or Chocolate Haze, is a nearly pure sativa known for its sweet chocolate flavor, resilient growth, and long-lasting mild euphoria. A major benefit is its fast flowering time - just 10 weeks after vegetating.

This quick timeline owes to its Cannalope Haze genetics. Indoors it yields a generous 450-500g/m2 and can produce monster 600-700g/plant yields outdoors.

Plants grow 100-150cm indoors and up to 200cm outside, suitable for both environments. It's a robust, forgiving strain great for beginners. Chocolope is ready for harvest in early October and provides uplifting, creative effects when cared for properly.

The fast flowering, high yields, and soaring sativa high make Chocolope a great pick for new and experienced growers alike.
