LSD-25 Auto Feminized Seeds from Fast Buds produce an indica-dominant autoflower known for deep purple colour, fast growth, and strong potency. Fast Buds bred this strain from Original Skunk and Auto Purple Kush, then refined it into a stable F5 feminized line. As a result, growers get a vigorous plant with a manageable structure and a standout look by harvest. For many growers, LSD-25 Auto Feminized Seeds remain one of the most recognisable purple strains in the Fast Buds range.
From early growth, the plant develops sturdy branching and a solid central frame. Bud sites stack closely along the stems, which helps the flowers build weight without making the plant difficult to handle. Most plants reach around 70 to 120 cm, so they fit comfortably in tents and indoor rooms while still producing generous yields. Fast Buds also positions this strain as easy to grow, which makes it suitable for beginners as well as more experienced growers.
The full cycle usually finishes in around 9 to 10 weeks from seed. Because of this relatively quick turnaround, many growers use it in fast indoor rotations or short outdoor seasons. Under good conditions, Fast Buds lists indoor yields of around 400 to 500 g/m², while outdoor plants can produce around 50 to 250 g per plant.
As flowering moves on, the plant begins to show the dark shades that made it famous. Buds often turn deep purple, and bright orange pistils stand out against the darker tones. At the same time, the flowers develop a thick, even resin layer, which gives them a frosty finish and strong bag appeal. Fast Buds also notes that most plants show purple colour, although some phenotypes may stay greener.
The terpene profile leans bold and grounded rather than sweet and light. Diesel, fuel, and smoked wood sit at the front, while berry, earthy, and woody notes add depth underneath. Because of this, LSD-25 Auto Feminized Seeds suit growers looking for a louder, more old-school aromatic profile. The effect is described by Fast Buds as an intense sativa high or cerebral time-warp, backed by THC above 21%, so the overall experience feels strong, heady, and long lasting.
