Growing Cannabis in Kingston
Indoor Growing
Indoor cultivation is popular in Kingston year-round. During Ontario's cold winters, indoor setups keep your garden producing. Many Kingston growers operate grow tents or dedicated rooms in basements, spare bedrooms, or garages.
For indoor growers in Kingston, we recommend compact autoflowering seeds that finish in 8-10 weeks and stay under 100cm tall — perfect for tents and small spaces. Read our grow cannabis at home in Canada and cannabis lighting guide to set up your indoor garden.
Outdoor Growing
Kingston's outdoor growing season runs roughly from May through October (southern), June through September (northern). Southern Ontario growers can transplant outdoors after the Victoria Day long weekend (late May). Choose mold-resistant strains, as August and September humidity can be brutal. For outdoor growing in Kingston, choose strains that are mold-resistant strains that handle Ontario's humidity, plus fast-finishing varieties for the northern regions.
