About Deadwood Feminised

South Africa is really two growing countries, and Deadwood does not behave the same way in both. North and east of the escarpment the rain arrives in summer, so this 72/28 indica does its flowering while the air is still heavy; in the Western Cape the rain comes in winter, so the same plant ripens through a dry autumn instead. Dense indica flowers at 15% THC are the wrong shape for a wet summer finish. Between Durban and Richards Bay, once humidity sits above 65% for days at a stretch, botrytis reaches the core of a cola before anything shows on the surface — defoliate early, space plants wider than feels necessary, and keep air moving under the canopy. That same density turns into an advantage on the Highveld: above 1 400 m the autumn nights go cold and dry, caryophyllene sharpens as the temperature drops, and a compact frame shrugs off a Free State storm that would flatten something taller.

Setting Up for South African Conditions

Outdoors, the province decides which problem you are actually solving.

KwaZulu-Natal and the subtropical coast. Humidity rather than heat is the limiting factor here. Whitefly and thrips peak from December through February, so introduce predatory mites (Phytoseiulus persimilis) before you see damage rather than after it. Airflow under the lower canopy matters more on this coast than anywhere else in the country.

The Highveld — Gauteng, Free State, North West. Frost closes the window at both ends. That suits a 7-9 weeks bloom, provided you start seeds under cover by early September and bank the vegetative growth before the December solstice. Above 1 400 m the ultraviolet index is high enough to push trichome production, but harden transplants off slowly or they bleach.

Western Cape. Flowering falls in the dry half of the year, which makes this the most forgiving outdoor condition in the country for Deadwood — the mould pressure that shapes every other region never arrives. The south-easter is your problem instead: weeks of sustained summer wind through December and January will tear an unstaked plant apart.

Indoors the location stops mattering and the numbers take over. Through a summer sitting above 30°C ambient, run lights overnight on a 6pm-6am cycle and you sidestep most heat stress without paying for cooling. Hold humidity at 55-65% in veg and 40-50% once flowers set; EC 1.0-1.4 vegetative, 1.6-2.0 at peak bloom; pH between 5.8 and 6.3 depending on medium.

Difficulty: easy. In flower for 7-9 weeks. Stands 130–220 cm. Indoors it returns 175–425 g/m². Outdoors, 450–650 g/plant a plant.

Aroma, Flavour and Effect

The first thing Deadwood does at 15% THC is settle a warm peppery spice at the back of the throat. The creative, focused effects follow within minutes, starting as weight behind the eyes and working down through the shoulders and limbs. Fifteen minutes in there is a physical stillness — not sedation so much as a disinclination to get up. Two to three hours at a moderate dose. Myrcene sits underneath all of it, adding more body, reinforcing the physical side.

The Aromatic Three

Leading with Caryophyllene, then Myrcene, and Bisabolol underneath. This trio turns up repeatedly in cultivars that win things, and it is why a jar of Deadwood tends to get a reaction the first time it is opened after curing. Caryophyllene sets the anchor, myrcene fills the middle, and bisabolol sits in the background doing the work that separates this from every other strain built on the same primary terpene.

Suitability and Recommendations

Who does well with Deadwood? Indoor growers who want the harvest date to be their decision. Outdoor growers who want to choose the moment flowering starts. Anyone with the room and the patience to veg it properly before flipping. It is rated easy, which in practice means a moderate learning curve that rewards attention without needing laboratory conditions. Sent nationwide in plain, unbranded packaging, with sourced grow data on every strain page.
