Description

Durban Thai x C99 Strain Info

The best of each parent is united in this cross – the electric, uplifting mentality of Durban Thai and the sugary, rapid-finishing character of C99. The outcome is an ecstatic plant that performs well indoors, outside, or in greenhouses, yielding resin-drenched colas and a unique aroma. It's ideal for Sativa fans who want a clean, imaginative high that persists for hours.

Genetics

Durban Thai x C99 combines Durban Thai Highflyer, a tall, spicy African-Asian Sativa, with the short, tropical-inclined Cinderella 99. The aim was to domesticate Durban Thai's stature and lengthy flower time without losing potency, scent, or energetic effect – and the outcome accomplishes this handily.

Flowering Time

This Sativa completes flowering in 63-72 days – a notable improvement on traditional landrace schedules. Outdoors, it’s usually ready by early to mid-October, bringing it within the reach of growers in temperate latitudes.

Yields

Durban Thai x C99 can produce high yields when well cared for. Indoors, you can anticipate around 450-600g/m² (1.5-2oz/ft2), and outdoor plants, if in a prime environment, can yield up to 450-750g (16-26.5oz) per plant.

Effects

The high is clear and strong, starting with an energetic buzz that's great for work, creativity, or social life. At its peak, the high is uplifting and heady without a heavy comedown – perfect for daytime use or extended, active sessions.

THC and CBD Levels

Accurate laboratory testing varies, but THC is generally between 16-24%. CBD content is negligible, so the effect is purely energetic and psychoactive.

Smell and Taste

The terpene profile is complex – anticipate incense and spice over sweet citrus and flowers. Silky smooth on the palate with an earthy note, expect a persistent sweet-spicy finish that lingers long after exhaling.

Grow Tips

Durban Thai x C99 grows strong and robust, adapting to a variety of environments. Its height is reasonable for a Sativa thanks to the C99 influence, but plants still benefit from training.

  • Responds well to topping, LST, and SCROG to control stretch and maximize light penetration.
  • Ensure good airflow in late flower – buds can pack in close.
  • Outdoors, place in a warm, sheltered location for best performance.
  • Manages nutrients easily, although excessive overfeeding at early stages should be avoided.

    • General impressions

      DTxC99 was one of the standout plants of the run and quickly proved itself to be something special. It grew with excellent vigor, maintained perfect health throughout the entire cycle, and handled everything without complaint. Structurally it was easy to work with, making for a very enjoyable plant from start to finish.

      The resin production was exceptional, coating the flowers in a thick layer of trichomes early that only became heavier as harvest approached. The buds finished dense and beautifully formed, with excellent bag appeal.

      What really set this phenotype apart was the terpene profile. It opened with distinctive notes of black licorice and musky incense, backed by orange rind and tropical fruit. It wasn't a generic fruity cultivar. The aroma had real depth and complexity, making it one of the most memorable terpene profiles I've grown.

      Overall, DTxC99 exceeded my expectations in every category. Outstanding plant health, excellent resin production, unique and complex terpenes, and top-quality finished flower make this a cultivar I'd recommend without hesitation. It's a strain that offers something genuinely different from the usual modern dessert profiles and deserves far more attention than it receives.
