Growing Cannabis in Victoria

Victoria, a southeastern state in Australia, has a diverse climate ranging from cool and temperate along the coast to alpine in the mountains, making it a unique environment for growing cannabis. Over the years, cannabis cultivation in Victoria has shifted from a clandestine activity to one that is regulated and legal for medicinal use and, to some extent, for personal use. This article provides insights into the legal framework, best practices, and challenges of cultivating cannabis in Victoria.

Legal Framework for Cannabis Cultivation

Medicinal Use

The Victorian government has made significant strides in the legalization of medicinal cannabis. The Access to Medicinal Cannabis Act 2016 was the first legal framework in place which allowed for the cultivation and manufacture of medicinal cannabis in Victoria. Patients with specific conditions, upon the recommendation of a registered healthcare professional, can access medicinal cannabis products.

Personal Use

Recreational cannabis is not legal in Victoria, but there has been a decriminalization approach for small possession amounts. As of the last update in 2021, possessing up to 50 grams of dried cannabis can lead to a warning, and subsequent offenses may result in fines or referrals to drug diversion programs. Cultivation for personal use is limited to two non-hydroponically grown plants per person, with a maximum of four plants per household.

It’s essential to regularly check the state government’s website or consult legal professionals to get up-to-date and accurate information on cannabis laws.

Cultivating Cannabis in Victoria’s Climate

Victoria’s diverse climate affects the growth of cannabis in various ways:

Coastal & Temperate Zones

In regions like Melbourne, cannabis growers can expect a cooler, maritime climate. Outdoor growers usually plant in the early spring and harvest in the late summer or early autumn. Sativa strains, which can handle a more extended flowering period, might be more suited to these zones.

Alpine & Mountainous Zones

These areas can be challenging for outdoor cannabis cultivation due to shorter growing seasons and potential frost. Indica strains or fast-flowering hybrids are preferred. Growers might consider greenhouse cultivation to protect plants from extreme weather conditions.

Indoor vs. Outdoor Cultivation

Indoor Cultivation

  • Controlled Environment: Indoor growers can control temperature, humidity, and light exposure, allowing for potentially higher yields and quality.
  • Multiple Harvests: Unlike outdoor cultivation which is dependent on seasons, indoor cultivation can have multiple cycles in a year.
  • Pest & Disease Control: Indoor setups generally have fewer issues with pests and diseases, but proper ventilation and cleanliness are essential.

Outdoor Cultivation

  • Natural Environment: Plants can benefit from natural sunlight, which might lead to more robust growth and potentially better cannabinoid profiles.
  • Lower Costs: Outdoor growing generally incurs lower costs, especially in terms of lighting and electricity.
  • Bigger Plants: Outdoor cannabis plants can grow significantly larger, leading to higher yields per plant.

Pests, Diseases, and Challenges


Common pests include spider mites, aphids, and caterpillars. Using organic, non-toxic insecticides or introducing natural predators, such as ladybugs, can help manage these pests.


Fungal infections like powdery mildew and bud rot can affect cannabis plants, especially in humid conditions. Proper spacing, good airflow, and preventive organic fungicides can help in disease management.


  • Odor Control: Cannabis plants, especially during flowering, can produce a strong odor which can be a concern for nearby residents.
  • Water Usage: Cannabis plants can use a significant amount of water, so growers need to be conscious of their water usage, especially during drier months.

Community and Education

With the increasing acceptance of cannabis cultivation in Victoria, several communities and organizations provide educational resources, workshops, and forums for aspiring growers. Engaging with local growing communities can offer insights, practical tips, and support for both novice and experienced growers.


Growing cannabis in Victoria, while subject to specific laws and regulations, can be a rewarding endeavor for both medicinal and personal use growers. Understanding the state’s diverse climate, choosing the right strains, and ensuring best practices can lead to a successful harvest. Continuous education and community engagement remain crucial for adapting to changing regulations and improving cultivation techniques.
