Durban Z

Durban Z or Sativa-Dominant Hybrid (~70/30) is a strain that typically contains THC levels between 22% – 28% (Can peak at 30%+ in top-shelf batches) and CBD levels ranging from Minimal (< 1%). Known for its Sweet citrus, tart fruit, and earthy-pine diesel profile, this strain has a growth expectation of being Medium to Tall (Inherits height from Durban Poison) in height, with a nutrient demand that is Moderate; sensitive to Nitrogen burn (go lighter than Indicas).

This Sativa-Dominant Hybrid (~70/30) is of the Genetype: Durban Poison x Z (Zkittlez). The Durban Z strain has 3 phases of the growing cycle.

The first phase is the Seedling Phase. Once you have decided to grow Durban Z in either soil or hydroponiclay, the ph levels need to be monitored. The ph level desired by Sativa-Dominant Hybrid (~70/30) is 6.0 – 6.8 and 5.5 – 6.0 hydroponically. During this infancy stage, Durban Z needs to maintain a target temperature of 70°F – 85°F (21°C – 29°C) for 2 to 3 weeks. Once the seed germinates, it will sprout it's first set of round leaves, or the cotyledons. If you are able to maintain the target humidity of 60% – 70%, the iconic serrated leaves will just begin to show themselves. During this critical Phase 1 of the Sativa-Dominant Hybrid (~70/30) growing cycle the plant is establishing a strong root sytem. Beginners often over water these fragile seedlings. Do not drown your seeds. You seedling Durban Z needs care and gentle light. The recommended light cycle for growing Durban Z is 18/6 or 20/4 for the first cycle, which should last .

The next is the Vegetative Phase. The Durban Z will focus entirely on size and structural integity. The temperature needs also change for phase 2. If a target temperature of 70°F – 80°F (21°C – 27°C) is maintained and a target humidity of 40% – 50% is achieved, the Sativa-Dominant Hybrid (~70/30) will grow stems, branches and plenty of large fan leaves. This Durban Poison x Z (Zkittlez) is trying to build it's own solar panel of leaves to absorb energy. It is critical to maintain a proper light cycle of 12/12 for the entire phase 2 schedule. This consistent energy will help plant grow bigger without producing flowers, focusing it's energy on growing tall and strong. Durban Z is at it's most resilient and may grow quickly. As phase 2 comes to an end, it may be topped or tied down, as it's training suitability is considered High; responds well to LST, Topping, and Scrog to manage height.

The most exciting phase, when growing Durban Poison x Z (Zkittlez) is the Flowering Phase. The plants adulthood lasts . It is at this phase that the light cycle changes for the last time. Durban Z will produce the most flowers when the light cycle is 12/12. Keep the temperature and humity controlled at 65°F – 75°F (18°C – 24°C) and 30% – 40% (To prevent bud rot in dense flowers) so you can really watch this plant strecth and almost double in height. It will want to start producing early into the flowering process.

You will know the Durban Z is ready when the white hairs (pistils) turn amber/brown and the resin glands (trichomes) look milky or cloudy, rather than clear. Cutting the plant down even a week too early can significantly reduce the potency and weight of your harvest. Patience in the flowering phase will provide the best possible outomce of Sativa-Dominant Hybrid (~70/30) with a desired gorwth profile that will be:
Vigorous vertical growth with dense, resinous, "sticky" buds

Growers Notes: Hobby Grower’s Strategy
As a grower, you should keep a close eye on the stretch. Because of its Durban Poison heritage, this plant can easily double or triple in height once you flip to the 12/12 light cycle. If you are growing in a tent, topping the plant early and using a trellis net (SCROG) is essential to keep the canopy even and prevent the buds from touching your lights.

Additionally, while it is a Sativa, the buds are noted for being surprisingly dense. This makes airflow critical in the final 3 weeks of flowering to prevent internal mold (botrytis).
