Outdoor

Outdoor cannabis cultivation refers to plants grown freely in open fields and other plots of land under natural sunlight. Outdoor cannabis gardening provides an environmentally friendly approach to growing that relies on the sun's rays, ambient rainfall, and atmospheric CO2 levels to minimize intervention compared with artificial indoor setups.

In the Northern Hemisphere, seedlings may first be started early indoors during late winter before tender young plants are repotted and transferred outdoors in early spring months after the final frost but before summer solstice. This long outdoor flowering period maximizes light exposure.

Plants flower naturally under summer's long days then transition to the ripening stage in early fall as daylight hours wane. Plants are harvested before the first killing frost or freeze arrives. Greenhouses also allow outdoor-style growing with supplemental lighting and protection from severe weather elements while still utilizing free sunlight.
