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.

Grow Tips

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
      Strong, easy to grow, almost odorless
    • Disadvantages
      Vegetation could go a little faster
    • General impressions

      Great variety, gonna grow her again! Makes a perfect base for hash. The flowering took 2 months + 3 days in dark and cold.
      Her aroma has strong earthy and minty notes. Goes hard on your throat but will probably be smoother after curing.
      Some say shet makes the skin peel off from your face… Well, it’s true!

      I’m growing this strain in my greenhouse together with cucumbers that look much happier with their neighbor from Herbies! 3 plants, each 90–110cm tall. I fertilize them twice a month and it seems to be enough. They are 72 days old now and the buds start to change color but I’m gonna keep them in there at least till September because the temperatures now get lower and it slows down the flowering. To me, the genetics is not that stable as 2 of them got sick at some point but now everything is fine. During my previous harvest I got around 80–100 grams from each bush. The bonus seeds that I received were Amnesia Lemon, I already got 190g from two bushes, they were 120cm tall each and the buds are pretty damn strong! I will update after harvesting the LSDs.

      Final update for the second grow. Pics from day 42. Got 2 out of 3 going. One green, one purple, one dud (see my previous review). From the two that survived one’s solid and the white pheno is noticeably weaker. Totally different from each other.

      Update day 32. The strain itself is nice. First time I bought just one seed and it was awesome. Because of that I grabbed a 3-pack… and now I get why people complain. Out of three only one turned out really good and that one’s the green pheno. The purple one looked cool but started acting weird around day 18. Twisted leaves, spots that turned into holes, then it dropped its big fans. Meanwhile the other seed in the same pot with the same care was totally fine.
      Finally figured out how to handle them and now they’re doing okay, but since they started preflower on day 16 they just didn’t have time to bulk up. By day 20 they were already covered in pistils. The last seed sprouted but looks..cursed. Leaves twisted, yellow stripes, no center growth at all. Super tiny seed too.
      So yeah.. fast, starts flowering super early, smell’s chill, good buzz. But genetics in the 3-pack were kinda sketchy… clear genetic lottery. Wouldn’t recommend for beginners.
