This feminised autoflowering hybrid from Fast Buds was refined over many generations from one of the breeder's earliest releases. Its ancestry combines Big Bud, Skunk, White Widow and Ruderalis, producing a compact plant with a sturdy frame that typically reaches 70 to 100 cm. Expect multiple bud sites with dense flowers wrapping around the stems, deep violet leaves and orange pistils. The aroma is earthy with a berry note, and its taste is rounded off by creamy sweetness that keeps the smoke smooth. The high is light at first, then settles into a relaxing body feeling that suits evenings. The plant responds well to low-stress training and is forgiving enough for beginners, while experienced growers will also find it dependable. It suits indoor and outdoor cultivation, including cooler northern regions.
