Growing Cannabis in Tasmania

Growing Cannabis in Tasmania refers to the cultivation of the Cannabis sativa plant in the island state of Tasmania, Australia. While the global perception of cannabis has evolved over the past decades, with several countries legalizing its use for medicinal and recreational purposes, the cultivation and possession of cannabis remains regulated in many regions, including Tasmania. This article delves into the historical, climatic, legal, and cultivation aspects of cannabis in Tasmania.

Historical Context

The use and cultivation of cannabis in Australia trace back to the 19th century, primarily for industrial hemp purposes. Tasmania, with its temperate maritime climate, became a favourable spot for cultivating the crop. In the latter half of the 20th century, as the global war on drugs intensified, Tasmania followed suit with stringent anti-cannabis laws. However, the turn of the 21st century witnessed a gradual shift towards acknowledging the medical benefits of cannabis, leading to regulatory changes.

Climatic Conditions and Cannabis Cultivation

Tasmania’s cool, maritime climate presents a unique environment for cannabis cultivation. Its geographical location means that the island experiences mild summers and cool winters, which can both benefit and challenge cannabis growers.


  • Long Vegetative Growth: The extended daylight hours during the Tasmanian summer can lead to longer vegetative growth for cannabis plants. This can result in larger plants with the potential for increased yields.
  • Pest Control: Cooler temperatures reduce the prevalence of many pests that plague cannabis crops in warmer regions.


  • Shorter Flowering Windows: Cannabis typically requires shorter daylight hours to enter the flowering phase. The Tasmanian summer can sometimes delay this onset, necessitating growers to either depend on autoflowering strains or manipulate light exposure in controlled environments.
  • Cold Stress: Sudden drops in temperature, especially during spring and autumn, can induce cold stress in cannabis plants. This can stunt growth or, in extreme cases, kill the plant.

Legal Landscape

As of the last update in 2021, the cultivation of cannabis for medicinal purposes is legal in Australia, provided growers possess the necessary licenses and permits. However, recreational cultivation and use remain illegal.

Medicinal Cannabis

Tasmania’s Controlled Access Scheme (CAS) allows patients with specific medical conditions to access medicinal cannabis. Growers wishing to cultivate cannabis for medicinal purposes must adhere to the regulatory framework set by both the Tasmanian government and the Australian government’s Office of Drug Control.

Recreational Cannabis

Cultivation, possession, and use of cannabis for recreational purposes are illegal in Tasmania. However, possession of small amounts is decriminalized, leading to a fine rather than criminal charges. Still, cultivation for personal use can result in significant penalties, including jail time.

Cultivation Techniques

Successful cannabis cultivation in Tasmania often requires techniques that cater to the island’s unique climate.

Indoor Cultivation

Given Tasmania’s unpredictable weather patterns, many growers opt for indoor cultivation. This method allows for greater control over temperature, light exposure, and humidity.

  • Lighting: Growers can use artificial lights to simulate the ideal day-night cycle, promoting vegetative growth or flowering as required.
  • Temperature Control: Indoor cultivation enables growers to maintain a consistent temperature, ensuring optimal growth and yield.

Outdoor Cultivation

While challenging, outdoor cultivation is feasible in Tasmania, especially during the warmer months.

  • Strain Selection: Opting for cold-resistant or early flowering strains can mitigate some of the climatic challenges.
  • Location: Choosing a sunny spot with good soil drainage can make a significant difference in plant health and yield.


Tasmania, with its unique climate, has the potential to be a fruitful region for cannabis cultivation. However, growers must navigate both the climatic challenges and the legal landscape. As perceptions around cannabis continue to evolve and the global industry grows, it remains to be seen how Tasmania will adapt and position itself in the world of cannabis cultivation.
