Oldtimer’s Haze


Haze was developed in California in the 1960s and 70s by crossing some of the best tropical sativas which had been imported during that period.

This mythic sativa, which has been the base for the breeding of the best hybrids for the past decades, was close to disappear in the 80s from the breeding scene, due the introduction of the skunk and indica strains.

Oldtimer’s Haze population has been preserved intact until today by Oldtimer, a british breeder, and then reproduced by our breeders using a wide variety of parental plants.

This pure Haze still preserves the genetic diversity that many present Haze lines have already lost, and it is possible to find phenotypes ranging from the mythic and nearly extinct Purple Haze to the most common Green Haze phenotype, and of course intermediate combinations as well.

Oldtimer’s Haze has an incalculable value for every preservationist, collector and breeder that is looking for a pure Haze population that still preserves the quality and original genetic diversity of this mythic sativa hybrid.

Latitude 0 -37
Genetics Stabilized hybrid of different tropical sativas from the 60s and 70s, mainly old Colombian sativas.
Structure Extreme tropical sativa with a very thin pale green leaf. Very thin and flexible stems that withstand the worst downpours and blizzards.
Bouquet Ancient  old school  sativa aroma: mature tropical fruits, spices, incense, wood and black liquor.
High Stimulating, mental effect. High THC/ low CBD ratio that produces an unlimited effect without ceiling. The green phenotypes produce a more sociable and euphoric effect, while the Purple Haze phenos tend to be more introspective.
Terpene profile It mainly contains the following monoterpenes: high amounts of beta mircene (2/3 parts), moderate amounts of trans ocimene and alpha pinene, and variability in the presence of small amounts of beta pinene. Sesquiterpenes: two thirds of beta-caryophyllene and one-third of alpha-humelene in the green phenotype (Green Haze), although the purple phenotype (Purple Haze) shows absence of sesquiterpenes.
Growing Tips For indoor growing, due to its extreme tropical sativa genotype, we mostly recommend her for the extreme sativa lovers, for breeding projects or for seed production. We recommend 11 (light)/13 (darkness) photoperiod for the flowering indoors, in order to boost the flowering, and to avoid reflowerings or excessive stretching in early flowering. Even reduce the photoperiod to 10/14 from the second half of flowering to favor its complete maturation.

Highly recommended for SCROG, horizontal or network growing due to its excellent yield in the lateral branches and its vigorous reaction to pruning.

For outdoor growing, it requires a tropical or subtropical climate in order to reach its full potential. However, it can easily be grown within latitudes of 20 -37 , where we recommend a warm and coastal climate. The use of a greenhouse is very helpful for its correct ripening in non tropical latitudes.

It requires low levels of nutrients, especially of nitrogen. For outdoor growing, it’s best to mix a good base of organic soil, rich in guano and worm casting, and then place the plants in a sunny place and leave them to grow at their own rhythm, almost without using fertilizers or stimulators.

Genetic analyses show that Oldtimer’s Haze has a very rare genotype, of extremely low genetic variability, showing direct kinship mainly with old colombian and panamanian sativas.

Due to its extreme stability, it is a very dominant plant in breeding projects, which shines again with all its vigor and original splendor when it is properly crossed with other strains, producing extraordinary hybrids with the mythical taste and effect that have made this sativa world-famous.

If you want to grow strains with the best traits of our Oldtimer’s Haze parental plants, which maintain their essence of tropical super sativa, but showing much more vigor, yield and potency, then we recommend Haze dominant hybrids, such as Haze x Kali China, Panama Haze or Purple Haze x Malawi.
