LSD-25 Auto by Fast Buds – Fast-Fruiting Indica Hybrid with Purple Buds & 21% THC

LSD-25 Auto by Fast Buds is a rapid-fire indica-dominant hybrid that blasts you into a psychedelic headspace while packing on dense, vividly purple buds in just 9–10 weeks from seed to harvest.

Are you tired of weak, slow-growing autos that barely color up or deliver underwhelming highs?

Many autoflowering strains promise big yields and bold effects but fall flat—leaving you with green, flavorless buds and a buzz that fades fast. You invest time, space, and nutrients only to end up with mediocre results that don’t inspire.

What if your first grow could actually blow your mind—literally?

Imagine harvesting chunky, resin-drenched flowers in under 10 weeks that glow in shades of violet and magenta, smell like a mix of diesel and red wine, and launch you into a creative, euphoric headspace. With LSD-25 Auto, that’s not a dream—it’s standard operating procedure.

Step-by-step growing guide

1. Germinate seeds in a dark, moist environment at 22–25 °C (71–77 °F) for 24–48 hours.
2. Plant directly in final pot (18–27 L) with well-draining soil to avoid transplant stress.
3. Provide 18–20 hours of light daily—no photoperiod switch needed.
4. Use low-stress training (LST) in week 2–3 to increase bud sites and control height.
5. Feed generously but reduce nitrogen during flowering to prevent nutrient burn.
6. Monitor trichomes—harvest when mostly cloudy for maximum THC and cerebral effect.
7. Dry slowly at 18–20 °C (64–68 °F) and 50–60% RH for 7–10 days before curing.

Frequently Asked Questions

Does LSD-25 Auto really turn purple without cold treatment?

Yes. Thanks to its Auto Purple Kush lineage, this strain develops vibrant purple, pink, and magenta hues naturally during flowering—no temperature drops required.

Is this strain suitable for beginner growers?

Absolutely. It’s resilient, forgiving of minor errors, and doesn’t require advanced techniques. Just keep it well-fed and avoid overwatering.

Can I grow LSD-25 Auto outdoors in hot climates?

Yes. It thrives in hot to moderate conditions and handles heat well. Just ensure good airflow to manage humidity and prevent mold.

How does the high compare to other autoflowers?

It’s far more cerebral and psychedelic than most. While many autos are heavy and sleepy, LSD-25 Auto delivers a sativa-driven, mind-expanding buzz with lasting body relaxation.

What’s the best way to maximize yield?

Use LST early, feed frequently with quality nutrients, and grow in a 20–27 L pot under strong lighting (600W+ LED or HPS).

Personal Experience of Pevgrow’s CEO (Alan)

I grew LSD-25 Auto in my 60x60x160 cm tent under a 600W HPS and was blown away by how fast it packed on weight. By week 6, the smell was already gassy and rich—like diesel soaked in red wine. I used LST on two of the three plants, and they responded perfectly, nearly doubling their bud sites. I didn’t top them—autos don’t forgive that—and stuck to a solid feeding schedule with moderate nitrogen in flower. At day 68, trichomes were 70% cloudy, 30% clear, so I harvested for maximum THC punch. After a 10-day dry and 3-week cure, the buds were rock-hard and shimmering with purple. Smoking it felt like stepping into a lucid dream—super clear-headed, creative, and gently euphoric. I’ve tried dozens of autos, but this one stands out. If you want a strain that looks, smells, and hits like a premium photoperiod but grows like an auto? This is it.
