Growing your own cannabis can be a rewarding experience, especially when you take the organic route. Organic cannabis is free from synthetic fertilizers and pesticides, making it a cleaner, more natural option. If you’re a Canadian resident with an Access to Cannabis for Medical Purposes Regulations (ACMPR) license, this guide will help you understand how to grow organic cannabis responsibly and legally.

Grow Organic Cannabis

Getting Started: Basic Requirements

ACMPR License

Before you begin, make sure you have a valid ACMPR license from Health Canada, which will outline specific rules around how much cannabis you’re allowed to grow and possess.

Organic Certification (Optional)

If you intend to sell your cannabis or simply want the “organic” label, you may need to obtain an organic certification. This generally involves inspections and adherence to stringent guidelines.

Seeds or Clones

Purchase organic seeds or clones to ensure that your plants are free from synthetic chemicals from the get-go.

Soil Preparation

Organic Soil

Choose an organic soil mix rich in nutrients. Organic soil typically contains compost, worm castings, and other natural materials that nourish your plants.

pH Levels

Maintain a soil pH level between 6.0 and 7.0. Use organic methods to adjust pH, such as lime to raise it or sulphur to lower it.

Feeding Your Plants

Organic Nutrients

Use organic fertilizers like fish emulsion, seaweed extracts, and bat guano. Read labels carefully to ensure that the product is 100% organic.

Compost Tea

Compost tea is an excellent organic supplement. Brew your own by steeping well-rotted compost in water.

Pest Control

Neem Oil

This natural insecticide can help control pests without harming your plants.

Companion Planting

Plants like marigold and lavender naturally repel some common cannabis pests.

Natural Predators

Consider introducing natural predators like ladybugs to control pest populations.


Filtered Water

Chlorinated tap water can harm your organic plants. Use filtered or dechlorinated water for better results.

Drip Systems

Consider a drip system to water your plants. This can help you avoid water waste, a principle in line with organic farming.

Harvesting and Curing


Two weeks before harvesting, flush your plants with clean, filtered water to remove any remaining nutrients.


Cut and trim your plants. Make sure to use clean, sterilized tools.


Cure the buds in glass jars, keeping them in a dark, cool place. Open the jars daily to let the buds breathe and check for mold.

Documentation and Legal Compliance

Keep records of all organic materials and methods used. This is not only good for your own tracking but also crucial for compliance with ACMPR regulations and potential organic certification.

Growing organic cannabis under an ┬ácan be a fulfilling venture. It’s not only better for your health but also for the environment. Remember to always adhere to the guidelines laid out by your ACMPR license and consult professionals for the best results. Happy growing!
