About Green Poison Auto

Where you grow Green Poison in Britain matters less than when you start it. This is one temperate maritime climate with a real north-south gradient: the south coast opens and closes its season around a fortnight either side of the central belt or upland Wales. Heat is almost never the constraint here. The wet finish is — rain sitting in dense flower through late September and October is what starts botrytis, and it ends more British outdoor crops than every insect on the plot combined. That puts the 8 weeks from germination flowering window and the bud structure ahead of everything else on this page. Under lights none of it applies: daylength, temperature and humidity are yours to set, and Green Poison can be run anywhere in the country on its merits.

The pressures on a British grow are fairly predictable. Damp is the first of them: botrytis in dense flower from September on, answered with open bud structure and moving air rather than with a spray. Indoors it is spider mite and thrips that arrive, and humidity above 60% in late bloom is what turns a contained problem into a lost room. Outdoors in a wet spring the slugs take more seedlings than every insect put together, and they do it overnight.

What Green Poison is actually like

Growers report euphoric, creative as the defining characteristics and our own notes agree. At 15% THC this indica sits where dose control starts to matter. A single bowl through a vaporiser at 185°C gives a manageable physical ease with the head still working, which is what most people want at the end of a day. Push the dose and it moves firmly towards sedation — the reason it tends to become a winter evening cultivar rather than an all-year one. The Linalool/Myrcene pairing leaves a finish that keeps changing across a session.

Best suited to quiet evenings, a film, recovery after exercise, and the hour before sleep.

Terpene breakdown

Primary: Linalool · Secondary: Myrcene · Tertiary: Caryophyllene. This combination turns up often in cultivars that win things, and it is usually the one growers comment on when a jar is opened for the first time after curing. Linalool anchors the aroma, myrcene occupies the middle, and caryophyllene sits behind both — which is the part that separates this strain from others sharing its primary terpene.

Who it suits

Green Poison suits growers with the basics in place. Understand pH, rough nutrient ratios and light cycles before you commit to it; it asks for competence rather than expertise. Autoflowering genetics take the light cycle out of the equation, which suits balcony growers, anyone working around British daylight hours, and anyone who wants the whole thing over quickly. The April to October season accommodates a bloom of 8 weeks from germination comfortably for outdoor growers across the country.

Stabilisation Notes — What This Means for Your Grow

Green Poison is an autoflowering line that has been progressed through five rounds of Royal King Genetics autoflower stabilisation. The autoflower trait is recessive — fixing it takes multi-generation work — and at F5 the auto trigger and finish window are welded across the pack.

Breeding Goal

Reach auto trigger and finish-window uniformity for the Green Poison pack.

Selection Focus

Chosen for resin output, a low-slung stature and a clean indica terpene fingerprint.

Pollen / Mother Source

Royal King Genetics in-house mother stock — pollen taken from a sibling male drawn from the same selected pheno population.
