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.

Regions including Spain, Portugal, the South of France, and Italy experience warm, sunny, and long growing seasons. Although cannabis plants thrive in these areas, dry climates and high temperatures can inflict stress and impact yields. Fortunately, several cultivars are well-equipped to deal with these conditions. 

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.

1. 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.

2. 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.

3. Sherbet Queen Automatic

Sherbet Queen Automatic loves to bask in the hot summer sun. Considering she receives enough water to keep her roots hydrated, she’ll produce a dense canopy of buds in hot and dry regions. This hardy strain descends from parent strains Pink Panties and Cookies Auto and possesses an indica-dominant genetic profile. She produces thick, tapered flowers housing a THC value of 20%—placing her among the strongest autos available. Enjoy tastes of fruit with every hit.

Grow her outdoors in small containers or transplant her directly into raised beds. She’ll grow to a maximum height of 120cm, but will remain at only 80cm with some LST. Expect an impressive yield of up to 150g/plant after a brief growing cycle of 8–9 weeks.

4. Mimosa Automatic

Mimosa Automatic earned her title thanks to the delicious terpenes embedded in her flowers. Just like her namesake beverage, she's invigorating and really takes the edge off. Her buds display a thick coating of trichomes and gorgeous shades of deep purple and dark green. Exposure to intense sunlight likely increases her taste and potency, as cannabis trichomes ramp up resin production to protect against UV rays. Her THC level of 21% synergises with citrusy terpenes to produce a cerebral and motivating high.

This cultivar does well outdoors, where she peaks at a height of 130cm. Sow companion plants such as basil and dill nearby to help defend against pests. Prepare to harvest 80–130g/plant just 9–10 weeks after germination.

5. Royal Jack Automatic

Royal Jack Automatic is a hardy hybrid blend of the legendary Jack Herer and autoflowering genetics. Optimal environmental conditions, like a sun-drenched southern European summer, can bring out the very best in the Royal Jack Automatic.

After germination these seeds will race to harvest in just 9-10 weeks. This kind of vigorous development makes two well-timed harvests possible. Weather permitting a bountiful harvest is a sure thing in a warm climate. Perfect for a first time discreet balcony/terrace grow.

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.

Further Information

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.

Data relating to the account remains relevant for as long as the consumer is in possession of an account. Therefore, the data remains documented for as long as the account exists.

SECTION 5 – COOKIES

Cookies are small information files that notify your computer of previous interactions with our website. These cookies are stored on your hard drive, not on our website. Essentially, when you use our website, your computer displays its cookies to us, informing our site that you have visited before. This allows our website to function more quickly and remember aspects related to your previous visits (such as your username), making your experience more convenient. At Royal Queen Seeds, we use two types of cookies: functional and analytical.

5.1 Functional Cookies

Functional cookies are used to enhance your online experience. Among other things, these cookies track what is added to your shopping cart. The use of these cookies does not require prior authorization.

5.2 Analytical Cookies

Analytical cookies are used for research and market analysis. The data collected with these analytical cookies is anonymous, making it unusable for third parties. The use of these cookies does not require prior authorization.

SECTION 5 – THIRD-PARTY SERVICES

Third-party services are required to conduct transactions and provide our services. In general, the third-party providers we use will only collect, use and disclose your information to the extent necessary to enable them to perform the services they provide to us.

However, certain third-party service providers, such as payment gateways and other payment transaction processors, have their own privacy policies regarding the information we must provide to them for your transactions.

We encourage you to read the privacy policies of these providers so that you can understand how these providers will handle your personal information.

In particular, certain suppliers may be located or have facilities located in a different jurisdiction than yours or ours. Therefore, if you choose to proceed with a transaction involving the services of a third party, your information may be subject to the laws of the jurisdiction in which that service provider or its facilities are located.

Once you leave our website or are redirected to a third-party website or application, you are no longer governed by this Privacy Policy or the Terms of Service of our website.

Web analytics service (anonymous data)

On this website we have integrated an element of a web analytics service (with anonymisation functionality). Web analytics can be defined as the gathering, processing and analysis of data about the behaviour of visitors to websites. An analytics service collects, among other things, data about which website a person came from (the so-called referrer), which sub-pages they visited or how often and for how long they visited a sub-page. Web analytics is mainly used for website optimisation and for a cost–benefit analysis of internet advertising.

Courier service

To complete deliveries we use a courier service. This courier service carries out the delivery between our company and the consumer's home. To complete these logistics, the company requires access to the consumer's name and address information.

Mailing service

Royal Queen Seeds uses a third-party mail service provider to send its newsletter. This provider has access to limited account information related to opt-in consent (e.g. email address).

Marketing services

Royal Queen Seeds has the support of a company that specialises in marketing and communication activities. Their access to personal information is very limited and mostly anonymous.

Payment services

At Royal Queen Seeds we use external payment services to handle our transactions (e.g. credit card payments).

SECTION 6 – SECURITY

To protect your personal information, we take reasonable precautions and follow industry standard best practices to ensure that it is not inappropriately lost, misused, accessed, disclosed, altered or destroyed.

If you provide us with your credit card information, the information is encrypted using secure socket layer technology (SSL) and stored using AES-256 encryption. Although no method of transmission over the internet or electronic storage is 100% secure, we follow all PCI-DSS requirements and implement additional industry standards that are commonly accepted. Information related to the account is protected with a hashing method. This method transforms the information into a generated hash. As a result, confidential information is protected and invisible, even to us. In addition, our databases are exceptionally protected against unauthorised access. For example, access to the database is only possible and permitted via approved IP addresses (e.g. from Royal Queen Seeds headquarters). Other attempts and addresses are rejected at all times.

Furthermore, data is anonymised as much as possible, so it cannot be directly linked to a specific consumer. With this data, however, we may be able to carry out market research and analysis. In addition, the third parties concerned (e.g. mailing service) are examined prior to our collaboration, comply with the GDPR from the EU and receive a processing agreement. Within Royal Queen Seeds, employees are assigned different access permissions. Specific permission provides access only to information that is strictly required to perform a task. Digital security measures are subject to change and must meet high requirements to ensure the safety of online customers. That is why, at Royal Queen Seeds, we appoint a security officer. Regular verification and improvement of security measures (where necessary) are part of the role.

SECTION 7 – CHANGES TO THIS PRIVACY POLICY

We reserve the right to modify this Privacy Policy at any time, so please check back regularly. Changes and clarifications will be effective immediately upon being published on the Website. If we make substantial changes to this policy, we will notify you here that it has been updated so you will know what information we collect, how we use it and under what circumstances, if any, we use and/or disclose it.

SECTION 8 – YOU HAVE THE RIGHT TO:
