Do you live in a southern climate? Maybe you reside along the mesmerising southern coast of Spain, or perhaps the quiet Italian countryside. No matter which location, you have the opportunity to grow towering sativa plants that produce huge yields of potent bud.

As most cannabis growers know, sativa strains thrive in warm southern climates that enjoy longer growing seasons. Given their origins in these climates, the increased sunshine, warmer temperatures, and prolonged summer helps them achieve their full potential.

Below, we’ll be discussing the five best sativa cultivars to grow in a southern climate. Although they possess unique traits, they have three things in common: impressive yields, pleasurable effects, and mouth-watering flavors.

1. Amnesia Haze

Amnesia Haze has become the choice Haze variety for the global cannabis community in recent years. This Dutch coffeeshop legend has earned a reputation as world-class stash. A tropical mix of South Asian and Jamaican genes, Amnesia Haze is considered by many to be the ultimate Haze hybrid. Outdoors under strong sunlight, Amnesia Haze can produce up to 24.7 oz. Light, regular doses of fertiliser, large containers, and patience are all that’s required to bring a scale-tipping 22% THC crop to harvest.

All good things come to those who wait. Flowering will likely take 12 weeks, and plants will require some LST and/or pruning to prevent them from exceeding 2m tall. After putting in the effort, though, it only takes a toke of this powerful, uplifting, and citrus-flavored weed to convince you.

2. Shogun

Shogun stands tall and proud in southern gardens. This hardy sativa loves to bask in sunlight, and makes use of every drop she has access to. Shogun claims a prestigious lineage; the progeny of Amnesia Haze and Gorilla Glue 4, she’s loaded with THC and boasts sativa-leaning genetics. Climbing to a maximum height of 74.1 inches outdoors, she’ll develop a wider and more productive canopy when topped during the first few weeks of the vegetative phase. Throw in some LST and/or main-lining, and you’ll secure a dense and even canopy during the flowering stage.

Shogun features a lengthy flowering time of up to 11 weeks. Prepare to harvest 22.9 – 26.5 oz at the end of this period. Her flowers churn out a THC content of 24% and an earthy and citrusy terpene profile. These phytochemicals synergise to produce a stimulating and motivating high that’s perfect for active stoners.

3. Royal Medic

Royal Medic is the perfect strain for warm-climate cultivators seeking high levels of CBD.
The product of crossing parent strains Juanita and Critical, Royal Medic inherited the very best traits from both cultivars. From Juanita, it obtained massive CBD levels. From Critical, it harnessed an exotic terpene profile and a decent serving of THC (10%).

Royal Medic surges to a height of 58.5 inches when grown outdoors in garden beds and containers. It produces dense and trichome-laden colas after a flowering time of 9 weeks, and plants left alone will put out a worthy 16.8 oz. However, a touch of training and a tight nutrient regimen will lead to an output of up to 18.5 oz. The cultivar offers a deeply relaxing and clear-headed high, which is supplemented by enormous levels of CBD. As you take each puff, you’ll also enjoy fruity and earthy flavors running along your tongue.

4. Haze Berry Automatic

Now, don’t get us wrong. Haze Berry Automatic tastes incredible when grown indoors. Throw in some sunlight and companion plants, though, and you’ll harvest one of the most flavorful strains you’ve ever encountered. RQS breeders created this terpene-rich cultivar using parent strains Haze Berry and Blueberry Auto. She emerged from the breeding project as a sativa-dominant specimen with a rapid growing cycle and impressive productivity.

These seeds will explode into fully mature plants 10–11 weeks after germination, reaching a height of 50.7 inches. After that, sharpen your trimming scissors in preparation to harvest 5.3 oz of sticky and aromatic flowers. These buds contain a subtle THC content of 13%, offering an easy-going and enjoyable high. And, speaking of those terpenes we mentioned before, notes of sweet blueberry dominate the mix.

5. Royal Haze Automatic

Royal Haze Automatic stems from the world-famous Haze lineage and features a balanced genetic profile of 50% sativa, 20% indica, and 30% ruderalis. Our master breeders created this specimen by crossing Amnesia Haze, Skunk, and ruderalis. Royal Haze Automatic races from seed to harvest in as little as 10 weeks. She doesn’t require an extended growing season, so southern cultivators could enjoy two harvests thanks to these staggering germination times.

She’ll top out at around 58.5 inches, providing a rewarding yield of 4.6 – 6.3 oz after a brief 5–7-week flowering time. A THC level of 15% and moderate amounts of CBD work together to produce a lucid and lightly stimulating high. Blaze these citrus-scented flowers in the morning to plunge into a state of creativity, light-heartedness, and relaxation.
