Fastbuds LSD-25 Auto Feminized Cannabis Seeds
LSD-25 Auto from Fast Buds is an indica-dominant autoflower known for its striking colour and strong potency. The strain was bred from LSD genetics and developed into a stable autoflower line that produces deep purple flowers and dense resin-covered buds. Because of this combination of colour, flavour, and strength, it has become one of the most recognisable strains in the Fast Buds catalogue.
From early growth, LSD-25 Auto develops a compact and sturdy structure. The plant grows with strong branches and short internodes, which helps support thick buds across the canopy. Most plants reach around 70 to 120 cm in height, making them manageable for indoor grow tents while still producing solid yields. Under good conditions, growers can harvest up to 500 g/m² indoors or around 50 to 250 g per plant outdoors.
The full cycle normally finishes in about eight to nine weeks from seed. Because of this relatively quick lifecycle, LSD-25 Auto fits well into fast production cycles. It also performs reliably across different environments, including indoor setups, outdoor gardens, and greenhouse grows.
Colour and Terpenes
As flowering progresses, LSD-25 Auto begins to display its signature colours. The buds often develop deep purple tones that contrast with bright orange pistils and a thick coating of frosty trichomes. This colourful appearance, combined with heavy resin production, gives the finished flowers strong visual appeal.
The terpene profile blends earthy, sweet, and slightly spicy notes. Alongside these deeper flavours, subtle hints of berry and citrus can also appear. Because of this layered profile, the strain offers a richer flavour compared with many standard autoflowers.
The effects tend to start with a gentle mental uplift before settling into a relaxing body sensation. Over time, the experience becomes deeply calming while the mind stays relatively clear. With THC levels reaching around 21%, LSD-25 Auto delivers a strong but balanced effect that suits relaxed evenings or slower moments during the day.
