BUDWEEDSEEDS

Warm regions with long growing seasons and mild autumns offer the conditions these genetics evolved for, allowing plants to reach their full size outdoors. Gardeners in Mediterranean or subtropical climates often buy sativa weed seeds because the late harvest, sometimes stretching into November, poses little risk when frost is rare. In northern latitudes the same strains frequently fail to finish before cold weather arrives. A greenhouse with supplemental heating can extend the window where the outdoor season falls short.
