1. Where Can I Buy Weed Seeds in Canada?

How to Legally Buy Weed Seeds in Canada: Licensed Retailers

In provinces where you can legally grow cannabis, you can purchase seeds from licensed retailers. These include government websites, dispensaries and seed banks. Seed banks offer the most variety, allowing you to find weed seeds matching your preferences and growing needs.

Dangers of Unlicensed Distributors

Shopping at unlicensed distributors is illegal and can result in poor-quality products. Since they aren’t regulated, there is no way to guarantee the safety of your purchase or the correct/complete strain information.

2. What Weed Seeds Should You Be Buying?

Seed Type

Feminized Seeds: This type is most common for at-home growers as it has been genetically altered to produce only female cannabis plants. Female plants produce buds that can be harvested for consumption, whereas male plants produce pollen.

Regular Seeds: These seeds have not been altered, so it is unknown if they will grow into male or female plants until they begin flowering. 

Autoflower Feminized Seeds: Consider this seed if you are a beginner grower or live in a climate with inconsistent sunlight. They are bred to flower based on age instead of the amount of light/darkness they receive. 

THC vs. CBD

CBD is non-psychoactive and does not produce a high on its own.

THC is psychoactive and does produce a high when consumed.

Strain Considerations

Indica Strains are often more CBD-dominant and are generally associated with a more relaxed full-body effect.

Sativa Strains are often more THC-dominant and are generally associated with a head high that provides a happy and social effect.

Hybrid Strains are typically a balance of THC and CBD and are generally associated with a mix of indica and sativa effects, depending on the ratios.

3. When is the Best Time to Buy Cannabis Seeds in Canada?

When to Start Germinating Your Weed Seed for Outdoor Growing

If you plan to grow your weed plant outside, you will want to aim for early spring (when there is no more frost). This means you should begin germinating the seed about 3-7 days before you want to plant.

Many experienced growers will begin the process a few weeks early and plant the germinated seed in an indoor pot. This allows the plant to develop bigger roots and a thicker stem before moving it outside.

Seed Availability: Don’t Miss Out

If you prefer a popular strain, contact the seed bank or monitor their site for re-stock. Some strains sell out fast, so subscribe for restock updates to avoid missing out.

Look for Promotions and Discounts

Be on the lookout for promotions or bulk purchase discounts from seed banks. Often around holidays or common discount times (like Boxing Day), there will be reduced or promotional pricing.

4. How to Properly Store and Germinate Your Seeds

Safe Storage

Humidity: You want to ensure a low-humidity environment to prevent early/unwanted germination.

Airtight Sealed Container: When possible, keep your weed seeds in their original packaging, which will have an airtight seal. Plastic baggies are a great alternative; just ensure you get all the air out before sealing them.

Cool Temperatures: To avoid significant temperature shifts, always choose a location with a relatively stable temperature. A cupboard works if you plan to germinate your cannabis seeds relatively soon; otherwise, a refrigerator is a good option (ideally, one that is not opened often to avoid temperature changes).

Darkness: Avoid exposing your weed seeds to light; you want to store them in a dark environment or a container.

A reminder to always keep your seeds and other cannabis products safe from pets and children.

Germination Methods

One of the most common forms of germination for weed seeds is the paper towel method. This involves placing the seed between two moist paper towels and storing it in a warm, dark place. You should check on the seeds daily to ensure the paper towels stay moist and look for the emergence of the taproot.

Another popular method is direct-to-soil. In this method, you plant the seed directly into and gently cover it with moist soil (about 1-2 cm deep). Like the paper towel method, you want to ensure the soil stays moist (not wet) and watch for the seedlings to sprout through the soil.

5. Legality and Regulations

Federal vs. Provincial Laws Surrounding Home-Growing Marijuana

The Cannabis Act (2018) made it legal to grow marijuana plants at home for personal consumption. Regulations include a limit of 4 plants per household (not per person), and all seeds must be purchased through a licensed retailer.

Currently, in Manitoba and Quebec, personal growth of Cannabis is still prohibited. However, Manitoba may amend this to allow for legal home cultivation in 2025.

Age Requirements to Purchase Weed Seeds

In provinces where it is legal to buy marijuana seeds and grow cannabis, the legal age is 19+, except in Alberta, which is 18+.

Importing Seeds into Canada

Be cautious when ordering seeds from outside of Canada. The government of Canada has an import process; you may be required to provide supplemental documents, and there is a risk of confiscation.

Landlord and Condo Regulations Surrounding Growing Cannabis

Landlords and Condo Boards may have separate regulations banning individuals from growing cannabis or restricting where it can be grown (e.g., not in shared spaces).

Reminders About Buying Marijuana Seeds in Canada

When purchasing weed seeds in Canada, be sure to review your province’s regulations. Consider your growing timeline, storage/germination requirements, and seed type and strain preference. Always purchase from a licensed distributor to ensure you buy responsibly and legally.
