Grease Monkey Seeds

Genetics & effects

Grease Monkey is a feminised photoperiod cross of Gorilla Glue #4 × Cookies & Cream, with a profile of approximately 70% indica and 30% sativa. Kiwi Seed Bank presents it as an intermediate-level option for growers who can manage vigorous branching, odour and humidity through the later stages of flowering.

Catalogue figures place THC at 15–20% and CBD at 0–0.8%. Individual experiences vary, but some people describe the effect as beginning with a happy or euphoric lift before becoming calming, deeply relaxed and occasionally sleepy. The flavour profile brings together sweet vanilla, earthy depth and pungent diesel. Caryophyllene, limonene and myrcene are the listed dominant terpenes.

Growing in New Zealand

Grease Monkey is suited to hot, dry and temperate conditions. In New Zealand, outdoor planting generally aligns with spring from September to November, once cold nights and frost are less likely. Choose a sunny, sheltered position with free-draining soil and enough room for a plant that may reach up to 200 cm.

This variety benefits from steady airflow and regular canopy checks, especially in humid districts. Its dense flowers can hold moisture, so sensible spacing, selective pruning and shelter from prolonged autumn rain may reduce the risk of mould. Strong aromas can become noticeable during flowering, making site planning important.

Indoor

Indoors, plants may reach up to 160 cm, although training can keep the canopy lower and more even. Low-stress training, topping and a well-supported branch structure can help light reach more flowering sites. Allow space between branches rather than encouraging an overly crowded centre.

• Flowering time: approximately 8–9 weeks
• Indoor height: up to 160 cm
• Indoor yield: up to 400 g/m²
• Difficulty: intermediate

Use effective ventilation and monitor humidity as flowers gain weight. Carbon filtration may also be useful where the strong diesel and earthy aroma needs to be managed.

Outdoor

Outdoors, Grease Monkey can develop into a broad, branching plant with a listed height of up to 200 cm. A warm, sunny position will usually be favourable, while stakes or a support frame can help branches carry heavier flowers. In cooler regions, a sheltered north-facing site may provide a longer window of warmth.

Water at the root zone and avoid leaving foliage wet late in the day. As autumn approaches, inspect dense flower clusters after rain and maintain airflow around the plant. Outdoor yield is listed at up to 500 g per plant, though actual performance depends on season, location and cultivation conditions.

Harvest

For New Zealand outdoor gardens, harvest will generally fall within March to May. Exact timing varies with spring planting date, local climate and seasonal weather. Look for swollen flowers, darkened pistils and the desired trichome appearance rather than relying only on a calendar date.

Indoors, the expected 8–9 week flowering period offers a more predictable guide. The finished flowers are described as dense, resinous and strongly scented, with sweet vanilla notes layered over diesel, earth and a lingering pungent finish.
