Sun-grown refers to cannabis plants cultivated outdoors under direct natural sunlight. Sun-grown contrasts with greenhouse-grown using light deprivation techniques or indoor grown using artificial lighting. With fewer environmental controls, sun-grown cannabis relies on the sun for energy often resulting in a more eco-friendly, sustainable profile that avoids electricity usage. However, yields tend to be lower per plant and more susceptible to inclement weather, mold, mildew and pests compared to carefully controlled indoor environments. When grown successfully, sun-grown cannabis develops robust expression of terpenes and may potentially offer superior flavor and potency qualities that some connoisseurs value compared to artificial lighting methods. But improperly grown plants can easily develop issues. While debated, full-term sun-grown whole flower maintains a following among outdoor purists when cultivated properly by skilled, attentive growers.
