About LSD Auto

Does LSD finish outdoors in Ireland? It does, planted out at the end of May and cut by early October. The 49/51 balance handles an Irish season without special treatment, which is most of the reason to choose it. Bloom takes 65-70 days seed to harvest, so the harvest date is set by the calendar far more than by your technique.

What should I expect to take off it? 550-650 gr/m2 indoors and 280-350 gr/plant outdoors are the published figures, and both assume a full light or a full season plus a root run to match. A tunnel gets you most of the way to the outdoor number; a windowsill will not. At 23% THC the effort is well spent either way.

Is it a sensible first grow? Yes. It survives the things that go wrong in a first attempt — forgotten waterings, a feed mixed by eye, a shed that is cold by morning — and still produces something worth curing.

Other questions that come up about LSD

Soil or coco? Coco with fertigation at EC 1.4-1.8 through bloom if you are there daily and want speed. Peat-free soil with slow amendments — fish, blood and bone, seaweed meal, rock phosphate — if you are not, and want flavour. Both suit this hybrid; the deciding factor is your week, not the plant.

How does it handle the weather here? Hybrid vigour covers most of what an Irish summer does. Keep the root zone under 28°C and do not transplant into a warm spell.

When does bloom feed start? Within a week of the first pistils. The 49/51 balance shifts demand quickly at the transition — phosphorus and potassium up, nitrogen down. Soil growers top-dress; coco and hydro switch formula immediately.

Tunnel, outdoors or indoors? A tunnel is the best value of the three here. Indoors you own the 65-70 days seed to harvest of bloom completely; outdoors the plant gets light no lamp matches and can reach 280-350 gr/plant, and pays for it in rain. Flowering: 65-70 days seed to harvest. Indoor yield: 550-650 gr/m2. Outdoor yield: 280-350 gr/plant. Plant height: 80-100 cm. Rated beginner difficulty.

Flavour, aroma and effect

LSD arrives in order. The first draw at 23% THC gives citrus with a bitter edge that lifts off the palate. The euphoric, creative, focused, calm character follows in minutes, as head and body together. Thinking stays clear while the muscles let go by degrees, which is what makes the dose, rather than the genetics, the thing that decides the evening. Caryophyllene underneath contributes warmth that keeps it anchored.

Terpene breakdown

Primary: Limonene · Secondary: Caryophyllene · Tertiary: Linalool. The three shift relative to each other across the cure. Straight off the dry the limonene dominates; three or four weeks sealed in glass at 16-18°C and the linalool underneath comes up to meet it. Vaporising between 180°C and 195°C catches the widest span, because heat takes the lighter linalool molecules first.

Who it suits

Who does well with LSD? Back-garden and balcony growers in Dublin, Cork and Galway. Anyone who wants a crop dry and put away before the autumn closes in. Indoor growers short of headroom. The autoflowering genetics run to their own clock, so there is no schedule to manage and no anxiety about light leaks. Rated beginner, which means a first grow with a basic setup and a bit of discipline about feeding will produce something worth having.
