LSD-25 Auto brings purple drama without the diva behavior. This 65% Indica/35% Sativa autoflower leans dark, gassy, and oddly glamorous, mixing berry sweetness with diesel fumes and smoked wood. At 21% THC, it has enough voltage to bend the room a little – then smooth it all into a relaxed, euphoric glow.

Description

LSD-25 Auto Strain Info

LSD-25 Auto is a feminized autoflowering strain with a 65% Indica/35% Sativa profile, 21% THC, and 1% CBD. It grows with the speed and reliability that make autos so useful, but its personality is anything but basic. Expect a vigorous plant that builds dense, resin-heavy buds, often showing deep purple tones as flowering moves along. The smoke feels relaxing at the core, yet the Sativa edge brings a bright cerebral twist that keeps the experience lifted rather than sleepy. Flavor-wise, it sits in loud-terp territory: berries over diesel, with earthy wood smoke hanging in the background.

Genetics

LSD-25 Auto comes from Original Skunk and Auto Purple Kush from Buddha Seeds, refined into a stable F5 feminized autoflower line. Original Skunk brings intensity, structure, and that old-school aromatic punch, while Auto Purple Kush adds deep coloration and a heavier Indica frame. Together, they create a fast, compact strain with strong resin production, vivid purple expression, and a terpene profile that feels built for fans of gassy cultivars.

Flowering Time

LSD-25 Auto finishes from seed to harvest in 63-70 days, or roughly 9-10 weeks. That quick cycle makes it a strong choice for growers who want fast turnover without sacrificing bag appeal. Stable light, low stress, and consistent feeding will help the plant move through its schedule cleanly, especially if you want those darker purple flowers to show their best side.

Yields

Indoors, LSD-25 Auto can produce around 1.3-1.6oz/ft² (400-500g/m²) under solid lighting and steady environmental control. Outdoors, plants can return about 1.8-8.8oz (50-250g) per plant, depending on climate, container size, and sunlight exposure. For a fast autoflower with such strong visual character, the production is practical, reliable, and nicely matched to its short life cycle.

Effects

The effect opens with an uplifting cerebral push, the kind that makes thoughts feel slightly brighter around the edges. Then the Indica body rolls in, bringing a calm physical ease that settles without flattening the whole evening. It can feel euphoric and time-warped, especially for newer users, so this is not a strain to underestimate just because it finishes quickly.

THC and CBD Levels

With 21% THC and 1% CBD, LSD-25 Auto delivers a strong experience that balances mental lift with body relaxation. The THC gives the high its euphoric punch, while the modest CBD presence may help soften the edges slightly. Beginners can enjoy it, but slow pacing is the smarter move.

Smell and Taste

The aroma is bold from the start: berry sweetness cuts through diesel fumes, while burnt wood adds a darker, smoky finish. Some notes lean toward red wine and fuel, giving the smoke a moody, cellar-door kind of charm. On the exhale, the earthy side comes forward, grounding the sweetness before it gets too candy-like.

Good to Know

LSD-25 Auto grows to about 2.3-3.9ft (70-120cm), with a strong central cola and supportive side branching. Its fast autoflower rhythm makes it beginner-friendly, but the dense buds and resin-heavy finish still reward careful environmental control. Treat it gently, keep the grow room clean, and let the color show up on its own schedule.

  • Use LST early to open the canopy without slowing growth.
  • Avoid heavy training after flowering begins, since autos have limited recovery time.
  • Keep airflow steady around dense purple buds to reduce moisture pressure.
  • Maintain stable temperatures late in the cycle to support darker color expression.
  • Harvest at full maturity for stronger diesel-wood flavor and better resin quality.

    • Advantages
      Every good strain must have its own unique characteristics that demonstrate why it's truly special. In our case, it's all about strength, beauty, and uniqueness...
    • Disadvantages
      Personally, perhaps due to lack of experience or understanding of certain aspects, the yield was low... in terms of buds... it turned out to be a modest little plant...
    • General impressions

      This is actually a pleasant surprise... Very pleasant... I think it's a must-have in any enthusiast's collection... It's very strong. As for the effect, the leaves are good for enthusiasts, but the resinous buds can really knock you out... No regrets, the plant is beautiful, very tasty and fragrant at the same time. Strong - but not too much... But you can never have too much of a good thing, so I recommend it...

    • Advantages
      Really strong but not quite couch-locked
    • Disadvantages
      I haven't noticed anything serious, but a large pan is needed
    • General impressions

      The name doesn't quite fit because I didn't notice anything psychedelic. It's just a good, strong, and fairly mellow smoke.

      9 out of 10. Incredible color, bright purple😍 The buds keep getting brighter, and the leaves are already half burgundy. They are very large and dense, very beautiful and fatty, and there aren't many of them. The effect is more indica

      It's great, but it might not be for everyone, as it really knocks you out.
