About Hash Plant Auto

Hash Plant carries linalool as its lead note: lavender with sweetness under it, the smell of a garden border in the evening. Myrcene sits beneath it and shows up second, adding weight and body underneath. The plant tests at 16% THC across a 80/20 split, though what decides whether any of this reaches the jar is the cure, not the seed.

Growing it for aroma

Growing Hash Plant for terpene expression and growing it for weight are not the same project, and it is worth deciding which one you are on. The Linalool/Myrcene/Caryophyllene profile does its best work in living soil, where the biology produces compounds a bottle does not contain. Good peat-free compost and worm castings are available in any garden centre here, which makes that approach far less specialist than it sounds.

Stop foliar spraying after the second week of bloom. Anything that lands on a developing trichome is still there at harvest and is tasted rather than seen. In the last three weeks the night temperature decides which terpenes lead: held at 16-18°C the linalool comes forward, while a warmer finish protects the lighter caryophyllene notes.

Then the cure, which is where Irish growers lose most of what they built. A ten to fourteen day hang wants 17°C and something near 58% humidity, and the ambient air here will not supply either for most of the year — a closed room and a small dehumidifier will. Into glass afterwards, burped twice daily for a fortnight. The myrcene layer arrives somewhere in weeks three and four, not before.

Flowering: 50-60 days. Indoor yield: up to 350 g/m2. Outdoor yield: 450 grams. Plant height: 90-120 cm. Medium. Rated easy difficulty.

What Hash Plant is like in practice

The catalogue lists happy, relaxed, sleepy, and that matches what growers here report back. At 16% THC this indica sits where the dose is the whole question. One bowl through a vaporiser at 185°C leaves the head working and the body easy, which is what most people are after on a weeknight. More than that moves it firmly towards sedation. The Linalool and Myrcene together leave a finish that keeps shifting across a session.

Suited to evenings in, recovery after work, and the hour before sleep.

Terpene breakdown

Primary: Linalool · Secondary: Myrcene · Tertiary: Caryophyllene. Temperature decides how much of this profile survives. Low vaporisation at 180-188°C keeps myrcene and caryophyllene audible over the linalool; run it hotter, or burn it, and all three collapse into one note that is pleasant enough and tells you nothing.

Who it suits

Hash Plant suits growers with the fundamentals in place. Understand pH, rough nutrient ratios and a light cycle before committing to it; it asks for competence rather than expertise. Autoflowering genetics remove the light schedule from the equation, which matters in a shed or a spare room where full darkness is not realistic. A bloom of 50-60 days fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
