Top 5 Autoflowering Strains For Warm Climates (2020 Update)
Autoflowering cannabis strains are a great way to achieve multiple harvests in warm environments. They are quick, easy to care for, and do not require a change in light cycle. Here are some of our best selections for warmer climates.
Autoflowering cannabis strains are popular amongst home-growers for many reasons; but their main asset is a fast growing cycle. Couple this with a warm climate (if you are fortunate enough to live in one), and you have a plant capable of producing multiple crops over the course of a year.
In this article, we take a look at the top 5 autoflowering strains that will flourish in warm environments. This list covers everything from sky-high sativas to couch-locking indicas and those in between—so you’re sure to find one that suits your needs.
WHITE WIDOW AUTOMATIC
No list would be complete without the inclusion of White Widow, and what better place to start than with it? Revered by many as one of the most famous cannabis strains in the world, White Widow Automatic does a fine job replicating the original strain, but with a much more reasonable growing time of 75–85 days.
This cultivar will thrive under the blazing sun, reaching a discreet height of roughly 50cm on average and producing around 190–240g/plant. The bud is pleasantly pungent—earthy and woody in both aroma and taste.

DIESEL AUTOMATIC
Diesel Automatic is a next generation autoflowering hybrid strain. Selective breeding of NYC Diesel and Lowryder #2 has given rise to the premier auto strain without compromise. Virtually every desirable trait from each parent has been fine-tuned and enhanced in the offspring.
A decade ago nobody would have believed it possible to harvest 100g+ of top-shelf bud per plant from outdoor autoflowering plants under 1m tall. And definitely not in a total growing time of 8 weeks. Diesel Automatic is the autoflowering strain that might finally dispel the myth that autos cannot measure up to photoperiod strains.
Diesel Automatic is in a league of its own. Ultra potent and productive with no obvious weaknesses or downside risk. In a warm climate with minimal fertilisation, this strain will amaze even seasoned cultivators with how fast and frosty the nuggs fill out. For beginners or those with just enough space for one plant this summer make sure it’s Diesel Automatic.

This three-way cross of Lemon Haze, Juanita la Lagrimosa, and ruderalis will produce a generous yield of up to 160g/plant. The bud has a strong, but not overwhelming, citrusy aroma that will entrance you alongside its 11% THC content and high CBD content.

ROYAL CRITICAL AUTOMATIC
An unabashed award-winning strain, Royal Critical Automatic is one of the most popular strains available here at Royal Queen Seeds. While not as potent as the original (containing 14% THC), this strain has been included for its ease and pace of growth.
Standing at around 55–65cm in height, don’t think this plant will come up short in its offerings. Taking just 9 weeks to reach harvest, its yield clocks in at around 165g/plant. Not bad for a plant so small in stature. In warm climates, Royal Critical Automatic will bloom beautiful, chunky buds for you to enjoy, taking on distinct aromas of wood, spice, and sweetness.

SHADE RATHER THAN SHELTER
If you are lucky enough to be growing marijuana outdoors in an idyllic environment with fertile soil, fresh water and long sunny days remember too much sun can be a bad thing.
Should temps rise above 28°C even the most robust autoflowering plants will get burned and have trouble photosynthesising. Invest in shading to protect your plants. Build a simple shade with some shade cloth and keep roots cool with some straw bedding on the top soil.

So, there you have it—those are our top 5 autoflowering strains for warm climates. If, however, this article was not "hot" enough for you (say, because you live in an arid region with seriously high temperatures), you may want to have a look at our blog on growing cannabis in drought conditions.
