The Best Weed Strains to Grow in High Heat Climates

Cultivating cannabis in hot climates offers a unique set of opportunities for growers. Although it might initially seem challenging, it is an ideal environment for certain strains to shine.

This list offers 10 of the best heat-resistant strains to grow in this kind of environment; however, there's more to success than picking the right strain. Understanding the climate can also go a long way to a successful harvest.

The two climates notorious for their hot growing seasons are tropical and steppe climates. What sets the two environments apart is their humidity levels.

Tropical climates offer a hotter and more humid growing environment for cannabis, while steppe climates have high temperatures and a dryer environment. This is why this article will be divided into two, one highlighting strains for a hot and dry climate and the other for a hot and humid climate.

High Temperature & Low Humidity:

LSD

For cannabis growers looking to maximize their yield in a hot climate, LSD is a top-tier choice. Its plants crave sunshine and warmth, making them ideal for locations with lots of sun and heat.

As for its yield, LSD can produce 17 to 22 ounces per plant outdoors under ideal conditions.

LSD Feminized Seeds

The LSD marijuana strain delivers a light-minded, heavy-body high. Its smoke will move you to sit yourself down and intensely enjoy the feelings of euphoria that it brings.

However, one point to remember when growing LSD cannabis is the humidity level. While it loves hot weather, this strain doesn't like a humid climate, which makes LSD a great strain to grow in arid conditions, like Steppe climates, but a poor choice for those growing cannabis in the tropics.

For those interested in growing LSD, we offer an Autoflower variant that's much easier to grow without sacrificing yield! Autoflower cannabis strains are ideal, especially if growing indoors or in a greenhouse.

Super Silver Haze

Super Silver Haze is a Sativa-dominant hybrid that blends Skunk #1, Northern Lights, and Haze genetics.

The resulting cultivar features the dense and resinous flowers of its Skunk and Northern Lights parents. For its Haze genetics, you’ll recognize its parent strain's flavor and effects.

Because of its dense and resinous bud structure that can hold moisture, Super Silver Haze is a sativa-hybrid best grown in hot and arid climates. Hot weather prevents excess moisture from seeping into the plants and causing mold growth. But outside of that, this strain is an excellent choice for places with extreme heat.

If you love the citrus flavor and invigorating effects of Super Silver Haze, then you'll also love its offspring, Super Lemon Haze. This sativa-hybrid requires the same growing conditions as Super Silver Haze but rewards you with flowers with a more pronounced citrusy flavor and aroma.

White Widow

When it comes to growing cannabis in places with warmer climates, White Widow is worth considering. Although this strain can be a bit picky about the environment you grow it in, it can thrive under Steppe conditions so long as the temperatures aren't through the roof. For the best results, grow this Indica-dominant strain in outdoor environments with temperatures that don't exceed 85°F.

Although we consider White Widow one of our heat-resistant cannabis strains, What sets it apart (and why it's on this list) is its ability to do the opposite. This indica-hybrid can handle drops in temperature from when the growing season is ending and harvest draws near. This is especially key in Steppe climates, which are notorious for their extreme temperatures.

If you want to grow from White Widow but aren’t sure it can tolerate the intense heat in your environment, give it a shot. Even if you don't have the right climate, don't fret! White Widow is an amazing indoor grow; in fact, this indica-hybrid thrives best indoors or in greenhouses and even comes in an autoflower version!

Do note that Granddaddy Purple plants can reach outdoor heights of 4 to 6 feet and harvest around October. If growing tall cannabis plants isn't a concern, you can expect Granddaddy Purple to produce a considerable yield of 14 to 21 ounces per plant.

If you want to grow Sour Diesel, know that you'll have to work for it, as this sativa hybrid can test a grower's skills. It's considered challenging to grow, requiring significant experience and expertise in areas like pruning and training to achieve a satisfactory yield. The plants also demand careful humidity management and aren't particularly resistant to pests, meaning you'll need a way to protect them from opportunistic insects. However, you won't have to worry about heat stress - it loves a hot, dry climate. Additionally, Sour Diesel requires specific nutrient intakes to ensure a successful yield, making it a strain that truly challenges the grower's prowess. The one saving grace that Sour Diesel has is that you won't have to worry about humidity management as much if you're growing in a place with a Steppe-like climate.

All in all, though, as difficult as it is to grow, Sour Diesel can be quite rewarding. A successful harvest can mean 17 to 21 ounces per plant with flowers that have THC content that range from 19% to 20%. So, if you aren't afraid of a challenge, consider Sour Diesel for your next grow. And if you prefer autoflowers, we have this strain also available in that variant.

Amnesia Haze

Amnesia Haze is a Sativa-dominant hybrid strain with a lineage of South Asian and Jamaican landrace strains, giving it the perfect genetics for thriving in hot and humid climates.

However, growing Amnesia Haze has its challenges. This sativa-hybrid has a longer flowering period, which may force those with a shorter growing season to cultivate this strain in a greenhouse. It's also worth noting that Amnesia Haze is particularly sensitive to environmental factors during flowering, so growing conditions must remain consistent, and you must protect the plants from pests.

Despite these factors, Amnesia Haze, also available in autoflower, is still a cut above the rest because it can tolerate high temperatures and humidity. Where other strains might fail to take off, Amnesia Haze thrives, making it the ideal choice for growing outdoors in hotter climates.

Trainwreck

Trainwreck is the best sativa-dominant strain to grow in regions with high humidity and temperatures. This is because it combines the genetics of Mexican sativa, Thai sativa, and Afghani indica, resulting in a cultivar that carries the three's best traits.

Trainwreck is a sativa-dominant hybrid with effects so potent they hit you like a freight train. This staple from Northern California delivers a piney, spicy aroma mixed with the smell of sweet lemon.

The heat-resistant strain has the shorter flowering period that Mexican sativas are known for and produces a considerable amount of buds that you'd typically see on Thai cannabis. Yet even with its dense buds, Trainwreck has a high resistance against mold and mildew.

The Afghani genetics on Trainwreck introduced more resistance. It also reduced its height, so even though it's a sativa-hybrid, a Trainwreck plant will only grow to about 4 to 7 feet tall outdoors, which isn't much if you consider that you'd be able to rake in 1 to 2 pounds of weed per plant. Weed that connoisseurs will confidently say you'd enjoy, thanks to its euphoria-filled, energetic cerebral buzz. In fact, this invigorating head high made Trainwreck one of the staples in Northern California.
