Growing notes

White Widow Auto is well-suited to indoor tents, outdoor gardens, greenhouses, and mixed-light environments. Plants reach 28–43 inches tall — plan vertical space accordingly indoors. The 9-week total cycle makes scheduling straightforward. Yields are solid for an autoflower, especially outdoors where conditions allow the plant to reach its XL potential. A manageable choice for newer growers.
