Frequently asked questions

Where do you ship?

We ship to Canada and the United States only. We do not ship internationally.

How does shipping work?

In Canada, standard shipping by Canada Post is $10 (4 to 11 business days, no tracking) and express shipping by courier is $25 (2 to 4 business days, with tracking). In the United States, express shipping is $25 (2 to 3 business days, with tracking). Orders over $200 get free express shipping with tracking, applied automatically at checkout. We ship every day: orders placed before 2:00 p.m. Eastern ship the same day, and later orders ship the next day.

Is shipping discreet?

Yes. Orders arrive in a plain box or envelope with no branding and nothing that identifies the contents. The outside shows only the shipping label with the address you entered and a return address. Inside is a printed copy of your order invoice.

Where can I read the germination guarantee?

Our guarantee covers at least 80% germination for 90 days after purchase, and seeds that do not meet it are replaced. Read the full terms on the shipping and germination guarantees. We do not offer refunds or store credit.

What is the difference between feminized and autoflower seeds?

Feminized seeds are bred to produce female plants and flower when the light cycle changes. Autoflower seeds flower with age no matter the light cycle, so they are usually smaller and faster. Compare them on the feminized and autoflower pages.

Which cannabis seeds suit beginners?

Many beginners start with feminized or autoflower seeds, because they avoid male plants and autoflowers stay compact. Check plant size and flowering time on each product page before you choose.

Which seeds are best for growing outdoors in Canada?

Because the Canadian season is short, look for autoflower and fast version genetics, or browse our September and October harvest collections.

Do I get free seeds with my order?

Yes. Every order includes free seeds, and the bigger your order, the more free seeds you get.

How many seeds are in a pack?

Pack sizes differ by product. The pack size is shown on every product page; many packs hold 5 seeds.

Where do your seeds come from?

We carry seeds from several breeders, and the genetics of each strain belong to the breeder that created it. We also offer our own Quebec line.

How can I order?

Add your seeds to the cart and go to checkout. Choose your shipping, then pay by credit card, e-transfer or Bitcoin. Your order invoice is emailed to you. To cancel or change an order, email info@montrealcannabis-seeds.ca the same day, before it ships.

Is Montreal Cannabis Seeds legit?

Yes. We have been in business for more than 10 years. Every order ships in plain packaging with a printed invoice inside, our germination guarantee is published on the site, and we reply to emails within 24 hours. You can also call us at 514-805-2741, Monday to Friday, 10 a.m. to 6 p.m.

Where can I buy cannabis seeds in Canada?

You can order online from Montreal Cannabis Seeds and have your seeds delivered anywhere in Canada. Choose feminized, autoflower, fast version, CBD, mixed packs or outdoor seeds, then pick Canada Post standard shipping ($10) or courier express ($25). Express shipping is free on orders over $200.

How do I germinate cannabis seeds?

A common method is to place the seed between two damp paper towels in a warm, dark spot, around 22 to 25 °C. Check it every day and keep the towels moist, not soaked. When a small white taproot appears, gently plant the seed in your growing medium, root pointing down. Handle the seed as little as possible.

How long do cannabis seeds take to germinate?

Fresh seeds usually sprout within 1 to 7 days, and some take a little longer. If your seeds do not sprout, our guarantee covers 80% germination for 90 days, and we replace the seeds. Read the shipping and germination guarantees for the details.

How should I store cannabis seeds?

Keep your seeds in a cool, dark and dry place, in a sealed container, away from heat, light and humidity. Stored this way, they stay viable longer. Remember that our germination guarantee lasts 90 days.

Are autoflower seeds always female?

Most autoflower seeds sold today are feminized, which means they are bred to produce female plants. Regular seeds can produce males. Check the product page to see whether a strain is feminized.

How long does it take to grow cannabis from seed to harvest?

It depends on the strain. Autoflowers are the fastest and generally finish in about 8 to 12 weeks from seed. Feminized photoperiod plants take longer, often 4 to 6 months, because they need a growing stage and a change in light to flower. Fast versions fall in between.

Can I grow cannabis seeds outdoors in Quebec, Ontario or British Columbia?

Many strains grow well outdoors in Canada. With a short season, autoflowers and fast versions are a smart choice because they finish before the cold arrives. Plant after the last frost. Browse our outdoor seeds, and check the rules for growing at home where you live.

What payment methods do you accept?

We accept credit card, e-transfer and Bitcoin. Your order invoice is emailed to you after you order.
