Frequently asked questions
When do I plant outdoors in Canada?
Start indoors in April or May, move plants out after the last frost, usually late May to early June depending on region.
What ruins most Canadian outdoor grows?
Autumn, not summer: bud rot from cool wet weather and frost before harvest. Early-finishing genetics solve both.
How much can one outdoor plant yield?
With sun and space, photoperiod plants commonly give 300 to 800 grams. Autoflowers give less per plant but allow two crops a season.
