C5 Haze is an old selected cutting of Northern Lights #5 x Haze C and is by far the most influential F1 sativa/indica hybrid of the modern era of cannabis breeding. Created in the Netherlands during the late 1980s by the famous breeder Neville Schoenmakers. NL#5HazeC became popular worldwide for its huge yields, very powerful long-lasting effects and high THC content, unheard of at the time, leading this strain to win many of the early cannabis cups.

Developed as a direct cross between the Afghani Northern Lights # 5 and the Haze C male, this vintage C5 cutting includes the indica and sativa parents (respectively) that have had the most impact on strain development in the last 35 years, also forming the main parental line of the best Dutch Haze hybrids of the ‘90s.

ACE Seeds was recently gifted with this original extraordinary old C5 Haze Clone, bred and selected by Neville himself in the late 80’s and was preserved by Yo Sammy who was so kind to share it with them.

C5 Haze x Kali China is the first hybrid offered by ACE Seeds using this glorious classic, maintaining the large sized and well-branched sativa structure, the very high yields and the powerful psychoactivity of the original C5, enriched by our highly worked Kali China, with its complex incense, fruity and hashish terpenes to the most classic Thai citrus and spicy palate of the C5, creating new ranges of terpene profiles, slightly reducing flowering to more moderate ripening times (especially outdoors), and improving the psychoactive quality with a more positive but still very powerful character.

C5 Haze x Kali China differs from HashPlant Haze x Kali China by more frequently producing sweeter, fruitier terpene profiles, and by having a slightly more sativa touch than its stepsister. Both hybrids are of very similar quality, equally vigorous, productive, powerful, resinous and aromatic. And although some phenotypes may need a few more weeks of flowering than usual, the final yields of both varieties are always very high, and can be truly astounding with proper care and ideal conditions.

Due to the extreme heterosis of the original NL/Haze F1 hybrid, this cross with the more stabilised Kali China still produces relatively variable offspring, allowing the grower to find different expressions, making this cross a very interesting and much more exciting option for those growers who are easily bored with a single phenotype and who prefer some variability. The high genetic recombination of this polyhybrid also allows the emergence of new and interesting terpene profiles and effects not previously found in its parents.

During the second half of flowering the floral structures bulk up nicely, forming long and heavy colas with a great flower to leaf ratio, tending to produce small foxtails during the last weeks of flowering, at which time some examples can show the beautiful purple hues inherited from Kali China. The production of this balanced sativa/indica Haze hybrid (but on steroids) is far superior to Oldtimer’s Haze hybrids and other sativa x Kali China hybrids such as Thai Chi.
