About Fat Purple Auto

Growing Fat Purple in Ireland is a question of rain and wind rather than of heat or latitude. The whole island runs temperate oceanic, so nowhere is meaningfully warmer than anywhere else — what changes as you move west is how many wet days land on the plant while it is in flower. Outdoors that makes bud structure and the 55-65 days of bloom the two things worth reading before anything else, because a dense cola and a wet October are a poor combination. Under a tunnel or under lights the argument disappears: Fat Purple is then judged on its genetics and on nothing else.

Growing it on this island

The pressures here are consistent and they are nearly all about water. Botrytis in dense flower from September onwards is the first, and it is answered with open structure, moving air and a roof — not with anything sprayed on afterwards. Indoors, spider mite and thrips arrive the way they always do, and humidity above 60% in late bloom is what turns a manageable problem into a lost room. Outdoors in a wet spring the slugs do more damage to seedlings than every insect on the plot, and they do it in a single night.

A polytunnel changes the arithmetic on Fat Purple more than any other single purchase. It adds a fortnight at both ends of the season, keeps the rain off the flower during the weeks that matter, and turns a marginal outdoor crop into a reliable one.

What Fat Purple is like in practice

The catalogue lists happy, euphoric, creative, calm, and that matches what growers here report back. At 20% 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. The three shift relative to each other across the cure. Straight off the dry the linalool dominates; three or four weeks sealed in glass at 16-18°C and the caryophyllene underneath comes up to meet it. Vaporising between 180°C and 195°C catches the widest span, because heat takes the lighter caryophyllene molecules first.

Who it suits

Fat Purple 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 55-65 days fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
