Growing cannabis at home in Canada: the basics
Where it's legal, the 4-plant rule, and what a first grow actually involves.
Federally, Canadian adults can grow up to four cannabis plants per residence for personal use. But the rules, and whether you can grow at all, depend on where you live.
First, check your province
- Quebec and Manitoba prohibit home growing: despite the federal allowance.
- Everywhere else permits up to 4 plants per residence (not per person), often with conditions like keeping them out of public view or securely stored.
Always confirm your provincial and municipal rules, and any landlord or strata restrictions, before starting. See our provinces guide.
What a first grow involves
Cannabis is a forgiving plant, but a good grow takes attention:
- Light: strong light is the single biggest factor. Outdoors needs full sun; indoors needs proper grow lights.
- Medium and nutrients: quality soil or a soilless mix, plus appropriate feeding.
- Air and humidity: good airflow prevents mould; stable humidity keeps plants healthy.
- Time: most plants take roughly 3 to 5 months from seed to harvest, then drying and curing after.
Seeds and starting out
Buy seeds or clones from provincially authorized retailers. Start with one or two beginner-friendly plants rather than maxing out at four, you’ll learn far more from a small, well-tended grow.

Frequently asked questions
How many cannabis plants can I grow at home in Canada?
Up to 4 plants per household federally, but Quebec and Manitoba ban home growing entirely, so check your province first.
Is it hard to grow cannabis at home?
A basic grow is manageable for beginners, especially with autoflower seeds. Expect to learn as you go; your first harvest won't be perfect, and that's normal.
How long does it take to grow cannabis?
Roughly 3 to 5 months from seed to dried bud, depending on the strain and setup. Autoflowers finish faster.
Where can I legally buy cannabis seeds?
From provincially authorized retailers, the same place you buy flower.

Legal age, where to buy, and where you can use it all change by province.
