LSD

LSD is the Barney's Farm cross of Mazar and Skunk #1 released in the early 2000s, named for the strain's psychedelic cerebral lift rather than any genuine ergoline relationship. The strain took third place at the High Times Cannabis Cup in 2008 and second place in the 2009 IC420 Growers Cup, anchoring Barney's hybrid catalogue alongside Pineapple Chunk and Tangerine Dream. Plants stay short, finish in nine weeks, and yield well above the catalogue average, with dense buds carrying a sweet-earth and skunky terpene profile. The high is unusually cerebral for an indica-dominant — most reviewers describe a clear-headed wave that lasts well into the second hour.

Terpene profile

The aromatic compounds below shape how LSD smells, tastes, and ultimately feels in the body.

  • Myrcene

    Sedating, musky, herbal — commonly linked to couch-lock effects.

    dominant
  • Caryophyllene

    Peppery and spicy — the only terpene that binds CB2 receptors, studied for anti-inflammatory action.

    secondary
  • Humulene

    Hoppy and earthy — appetite-suppressing and shared with hops and sage.

    secondary
  • Pinene

    Alert and pine-forward — associated with mental clarity and bronchodilation.

Lineage

LSD traces to Mazar × Skunk #1. The cross sits in the Mazar / Skunk family, which influences both the terpene profile and the flowering structure described above.

Feed schedule for LSD

These EC and NPK targets are starting points calibrated for the strain's Indica lean and easy difficulty rating — not gospel. Drop 15-20% off any EC ceiling on your first run and let the plant tell you where it actually wants to feed.

What to expect through the grow cycle

LSD is documented with a 9-week flower and a compact stretch typical of indica-leaning structure. The visual below maps a documented 13-week cycle built from 4weeks of vegetative growth and the strain's published flowering window.

Published grow reports for LSD concentrate the most observational notes on the late-flower ripening window. This timeline is descriptive — it reflects what reports document, not a how-to. Actual week-to-week behaviour varies with phenotype, light intensity, pot size, and environment.

Phase details
Veg (weeks 1-4)
The documented vegetative period for LSD. Plants establish root structure, leaf canopy, and node count before flower triggering, with a easy difficulty rating shaping how forgiving the early canopy work tends to be.
Stretch (weeks 5-7)
LSD is documented as having moderate stretch. Reports describe the plant roughly doubling in height during this phase as the indica-leaning structure establishes its final flowering frame.
Bud sites (weeks 8-9)
Pre-flowers form at the nodes and calyxes begin to develop. Grow reports for LSDnote this as the window where the canopy's eventual bud distribution becomes visible.
Bud development (weeks 10-11)
Flowers thicken and calyxes fatten through this phase. Documented LSD runs show the bulk of visible flower mass accumulating here, with resin production accelerating toward the end.
Ripening (week 12)
Trichomes transition from clear toward cloudy and amber. Reports for LSD describe the Myrcene-led terpene profile maturing through this window, with aroma sharpening week over week.
Final (week 13)
Calyx swelling is documented as complete and the harvest window opens. Published LSD runs end here, within the 8-9 week flowering range reported by the breeder.

Common questions about LSD

Why is the strain called LSD?

The name refers to the psychedelic-leaning cerebral high — fractal, color-saturated, mildly visual at high doses — rather than any actual relationship to lysergic acid. The name is purely descriptive marketing.

Is LSD beginner-friendly to grow?

Yes. It stays short, resists mold and pests, finishes in nine weeks, and yields heavily. It is one of the easier Cup-winning strains for a first grow.

Strains similar to LSD

These picks lean on the same terpene profile and parent genetics as LSD — shared dominant terps, overlapping lineage, and matching indica/sativa lean. No star ratings or popularity contests, just overlap on the traits that actually drive a similar grow and smoke.
