Australia's Best Autoflowering Seeds to Grow Outdoors - 2023 UPDATE

Australia's Best Autoflowering Seeds to Grow Outdoors - 2023 UPDATE

Australia is an enormous landmass with a number of microclimates from the snowy mountains of Tasmania to the tropical jungle on the north coast. Growers of cannabis and other crops are concentrated mainly on the coast as inland is mainly arid desert.

Australia offers a unique environment to grow autoflowers

Certain areas of the continent, such as Sydney, enjoy a beautiful Mediterranean-style climate all year round, averaging 340 sunny days a year. However, rainfall is scarce, so you'll need to ensure your plants are well-watered.

However, the temperature of these regions is almost perfect for growing cannabis – with average highs of 26℃ and a balmy low of 16℃.

Other areas of Australia, such as Cairns, experience tropical weather with hot and sticky summers and mild, dry winters.

Not only do these locations feature excellent temperatures for optimal cannabis growth – an average high of 31℃ with an average low of 18℃ – they also receive plenty of rainfall.

Why autoflowers are ideal for the Australian climate

Autoflowers, with their short growing season, are ideal for cultivation in Australia as it is easily possible to enjoy multiple harvests each year.

Bountiful sunshine allows autos to flourish and reap rich rewards, so if you are lucky enough to live Down Under, you might as well take advantage of the latest generation of high-quality auto flowers seeds.
