Best Outdoor Cannabis Strains To Grow In Italy

Want to grow amazing outdoor weed in Italy? Here are the top 10 strains picked by our experts for both Northern and Southern Italian cultivators.

Whether you live in Milan and want to grow cannabis on a balcony or you happen to have a countryside haven in Sicily, we've got 10 amazing weed strains for the outdoor cannabis grower in Italy to consider cropping this season.



Italy is known for having some of the best food and fashion in the world. But besides being a great place to find pizza, Chianti, and Prada, Italy is also one of the best places in Europe for outdoor cannabis cultivation. Perhaps only rivalled by Spain, which has a similar climate, some of the finest weed in Europe is grown in Southern Italy.

But cannabis growers in Northern Italy can also achieve great results, so long as they choose suitable strains and time their harvests right. With the right genetics and some aforethought, you can crop an impressive harvest of frosty bud, well before the real cold sets in.


From the foot of the Alps down to Florence, the climate in Northern Italy is vastly different from the warmer Mediterranean climate down south. Chilly winter temperatures and the threat of spring frost can make outdoor growing seem daunting, but it really doesn’t need to be! Outdoor growers in these locations can outsmart Mother Nature’s tantrums by planting in pots, allowing them to move plants inside should the weather take a temporary turn for the worse.

If you’re north of Florence and don’t want your outdoor weed falling victim to frost, it is best to wait until spring is well underway—around mid-May. If you’re even further up north, you may want to wait until June or even July before bringing out your plants.


Excellent weed growing conditions can be found south of Florence, all the way down the western Mediterranean coast where the climate favours a wide variety of cannabis strains. Southward along the Adriatic coast in the East of the “boot”, the climate is subtropical, still warm and sunny, but humid. In the southernmost parts of the country, like Sicily, the climate is very hot and dry, and growers will need to protect their plants from the intense sun.

If you’re south of Rome, you can start outdoors in spring as early as April. If you’re living on the Adriatic coast, you’ll want to give it a little more time and start your crops at the end of April or in early May.

That being said, you can always start your plants indoors so they can safely move through the seedling stage before being exposed to the elements. The best way to go about this is to use Zamnesia Smart Start and put your seedlings under a CFL bulb or on a sunny windowsill. After a few weeks, when there is no risk of frost, you can set your plants outside.



Northern Italy

If you live in northern urban areas like Turin, Milan, or Trento, there is the possibility for frost in spring and rains in autumn to ruin your hard work. This makes year-round outdoor growing, unfortunately, impossible. However, with fast-flowering strains, you can easily crop high-quality cannabis during the summer growing season, allowing yourself plenty of time before and after seasonal threats. Autoflowers are a particularly good choice as they grow much quicker than photoperiod cannabis. Look for robust strains that are resistant to mould, too.

Southern Italy

Rain and frost won’t be a problem down south, so you have more options when choosing cannabis seeds. You can plant long-flowering sativas that love the sun and may need until late October to finish flowering. Of course, you can still plant autoflowers if that’s your thing. They may not get as large or yield as much as most photoperiod varieties, but due to their fast growth and good outdoor conditions, you can harvest numerous crops per season and per year. That said, make sure the intense southern sun doesn’t become a problem on its own. Protect your plants with sun shading and water them frequently during the hot summer.


We will now take a look at the best cannabis strains to grow outdoors in Italy. Let’s start our list with 5 cultivars best suited for Northern Italy, followed by 5 strains that we recommend for those growing in the South.


We kick off by discussing the best strains for Northern Italy. Let's go!

Follow these tips to achieve optimal results when growing weed outdoors in Italy.

Northern Italy

  • When choosing cannabis seeds, check their estimated outdoor harvest times. Choose strains that will be ready before the bad weather hits in autumn. Consider growing autoflowers as they won’t take as long as photoperiod varieties.
  • Look into cannabis strains resistant to mould and cold temperatures. Indicas are, in general, better suited for colder climates than sativas.
  • Keep an eye on your local weather report so you know ahead of time if a frost or thunderstorm is expected. Growing your outdoor cannabis plants in pots can give you flexibility should you need to shelter them in a hurry.

Southern Italy

  • Cannabis needs plenty of sun, but too much isn’t good either! In Southern Italy, your plants will need shading and frequent watering during high temperatures and intense sun in July and August.

Happy growing!
