AUTOFLOWERING GRANDADDY PURPLE
Price range: $65.00 through $255.00
Grandaddy Purple Autoflowering blends the legendary deep color and grape-like aroma of the classic Grandaddy Purple with the efficiency of automatic flowering genetics. Plants grow stocky and symmetrical, forming broad leaves and compact buds that gradually shift from green to violet and rich purple hues under cool night conditions. The fragrance is distinctively sweet with earthy and berry undertones, making it one of the most ornamental autos available. Its short stature and reliable timing make it ideal for growers seeking decorative, aromatic plants with minimal maintenance.
Seeds germinate within 3–6 days at 72–82 °F (22–28 °C). Plants typically reach 60–90 cm (24–36 in) in height and finish about 9–10 weeks from seed. Use well-drained soil, moderate feeding, and ample light exposure to enhance color and density. Cooler nights toward the end of flowering will deepen pigmentation. Performs consistently in both indoor gardens and temperate outdoor climates where nighttime temperatures allow color to develop fully.
