Question 1

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

Accepted Answer

Autoflower strains take 8-12 weeks total from seed to harvest. Photoperiod strains take 4-8 weeks in vegetative stage plus 8-12 weeks flowering, totaling 12-20+ weeks. Add 2-4 weeks for drying and curing before consumption.

Question 2

What are the stages of cannabis growth?

Accepted Answer

Cannabis grows through 8 main stages: Germination (1 week), Seedling (2 weeks), Vegetative growth (2-8 weeks), Pre-flower/Transition (1 week), Flowering (7-12 weeks), Harvest (1 day), Drying (7-14 days), and Curing (2+ weeks).

Question 3

When should I switch my cannabis plant to flowering?

Accepted Answer

For photoperiod plants, switch to 12/12 light when plants reach 50% of desired final height (they stretch during flower). Most growers veg for 4-8 weeks. Autoflowers switch automatically around weeks 3-4, so no light schedule change is needed.

Question 4

How do I know when my cannabis is ready to harvest?

Accepted Answer

Check trichomes with a magnifier: clear = too early, cloudy white = peak THC, amber = more relaxing/sedative. Also watch for pistils turning orange/brown (70-90% changed). Most strains are ready 8-12 weeks into flowering.

Question 5

What is the difference between autoflower and photoperiod cannabis?

Accepted Answer

Autoflowers flower automatically based on age (3-4 weeks) regardless of light schedule, making them faster (8-12 weeks total) and easier. Photoperiods require a 12/12 light schedule to flower but allow longer veg time for bigger plants and higher yields.
