What's the easiest cannabis strain to grow for beginners?

Autoflower strains are the easiest choice for first-time growers. They flower automatically regardless of light schedule and finish in 8-10 weeks.

How often should I water cannabis seedlings?

Water seedlings when the top inch of soil feels dry — usually every 2-3 days. Overwatering is the most common beginner mistake.

Do I need special lights to grow cannabis indoors?

Yes. Cannabis needs strong light to produce quality buds. LED grow lights are the most popular choice — they run cool, use less electricity, and last for years.

When is the best time to harvest cannabis?

Harvest timing depends on trichome colour. When most trichomes turn milky white with some amber, it's time.

What's the difference between autoflower and feminized seeds?

Feminized seeds produce female plants but need a 12/12 light schedule to flower. Autoflower seeds flower automatically based on age, finishing faster but usually yielding slightly less.

Can I grow cannabis outdoors in Canada?

Absolutely. Canadian summers provide enough light and warmth for outdoor growing from May to October.
