About Redwood Kush Feminised

Redwood Kush carries caryophyllene as its lead note: peppercorn and warm timber, dry rather than sweet, catching slightly at the back of the throat. Myrcene sits beneath it and shows up second, adding weight and body underneath. The plant tests at 24% THC across a 47/53 split, though what decides whether any of this reaches the jar is the cure, not the seed.

Growing it for aroma

Growing Redwood Kush for terpene expression and growing it for weight are not the same project, and it is worth deciding which one you are on. The Caryophyllene/Myrcene/Humulene 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 caryophyllene comes forward, while a warmer finish protects the lighter humulene 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: 9-10 weeks. Indoor yield: Up to 300g/m². Outdoor yield: Up to 300 gr. Plant height: Short. Rated easy difficulty.

What Redwood Kush is like in practice

The catalogue lists relaxed, happy, euphoric, and that matches what growers here report back. At 24% THC this hybrid sits where the balance is the argument for it. Small doses stay functional, larger ones relax properly, and the 47/53 split means the direction is set by the amount rather than fixed by the plant. The Caryophyllene and Myrcene together leave warmth and spice, drying on the exhale.

Suited to most occasions, with the dose doing the steering.

Terpene breakdown

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

Who it suits

Redwood Kush 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. Photoperiod genetics leave plant size and harvest date under your control — veg longer for a bigger plant, or flip early when the ceiling is low. A bloom of 9-10 weeks fits inside the season here for outdoor growers, with a tunnel making it comfortable rather than tight.
