Genetics & Origin of Karel's Haze
The Super Sativa Seed Club calls Karel's Haze its new pride – a hybrid for which the in-house Old School Haze (OSH) was crossed with Chem Dog OG Fire. The breeder gives the ratio as 70% Sativa to 30% Indica. According to the manufacturer, the OG side shows in fat, frosty flowers; among the offspring there are fruity as well as gassy phenotypes that are worth searching for. That is exactly what regular seeds are intended for: the seeds grow into male and female plants, so you can select, choose a mother plant or carry on crossing yourself. The strain is photoperiod. The breeder does not state a THC or CBD value. Also regular and from the same breeder is Karel's Herer Haze Regular.
Who Is Karel's Haze For?
Karel's Haze is a Haze hybrid with 8 to 9 weeks of flowering. It suits:
- Selectors looking for fruity or gassy phenotypes
- Hobby breeders who want to carry on working with regular seeds
- Haze fans who do not want to plan for a very long flowering time
- Extract fans who process frosty, resinous flowers
- Consumers who like a smooth smoke with a distinct head effect
It is less suitable for very low rooms and for anyone who wants only female plants without selection. You can find more regular lines under regular seeds.
Growing Karel's Haze: Indoor & Outdoor
Indoor Growing
According to the Super Sativa Seed Club, you can expect ripe flowers after 8 to 9 weeks of flowering. The plants grow medium-sized to tall; the breeder does not state a height in centimetres or a yield in g/m², and speaks of frosty plants that yield well. Its tip: top in the vegetative phase, i.e. remove the shoot tip. That way you avoid plants with only one main shoot and get more branching. With regular seeds, you germinate more seeds than you want to keep and determine the sex in pre-flowering; you remove male plants if pollination is not wanted. You will find the basics on training and determining the sex in the Growpedia.
Outdoor Growing
For open ground, the breeder gives no information of its own: neither a harvest date nor a height or a yield per plant is stated. Expect medium-sized to tall plants, give them sufficient space and choose a sunny spot sheltered from the wind. Topping in the vegetative phase, which the breeder recommends, makes for more heavily branched plants outdoors too. You can find more regular strains for outdoors under regular outdoor seeds. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Karel's Haze
The Super Sativa Seed Club describes the flavour as multi-layered: tropical Sativa lime, plus citrus and a dark, gassy aftertaste. The breeder sums up the scent as gassy, tropical, lemon and pungent; depending on the phenotype, the profile turns out more fruity or more gassy. The breeder speaks of a beautiful terpene profile that lends itself well to extractions; the manufacturer does not give a lab terpene profile. According to the manufacturer, the smoke is very smooth, but after a few puffs a powerful head effect sets in; it describes the effect as creative, giggly and heavily intoxicating. The breeder does not give a THC value, so we do not state a figure. With regular seeds, aroma and strength can vary from plant to plant. How intense the effect is depends on phenotype, dose and personal tolerance.
