Growing Conditions in Iowa
May through September. The state's rich prairie soil is excellent for cannabis but the short season limits outdoor photoperiod grows. With a cold climate and roughly 160 frost-free days, Iowa growers tend to do best with autoflowers, fast-finishing indicas, cold-hardy hybrids. Indoor growing strongly recommended. The rich soil would support excellent outdoor grows, but season length and legal restrictions make indoor the practical choice.
