Texas climate: what to plan for

Texas offers one of the longest outdoor seasons in the country, with intense sun and high heat from late spring through fall. That’s ideal for vigorous, sun-loving sativas and hardy hybrids that can drink up the long season and produce big yields.

The catch is the humidity in East and coastal Texas, which raises the risk of bud rot and powdery mildew late in flower. There, favor airy, sativa-leaning structures and read our mold-prevention tips. In arid West Texas, heat and water are the main concerns.

When to plant outdoors in Texas

Most Texas growers plant photoperiod seeds outdoors after the last frost in spring (often March–April), let them veg through the long days, and harvest from late September into October as nights lengthen.

Autoflowers like Blue Dream Auto give more flexibility — start them in spring or summer, and you can often fit more than one cycle, timing harvests around the most humid stretches. See our outdoor growing guide and how to choose an outdoor grow spot.
