Genetics & Origin of Brainkiller Haze
According to Vision Seeds, Brainkiller Haze is an almost pure Haze with 90% Sativa and 10% Indica. The breeder does not reveal exactly which Haze lines were crossed. It describes the strain as pure Sativa power with extreme yield potential and a typical old-school Haze profile. According to the manufacturer, the THC content is about 22% and the CBD content is low. Characteristic features are the tall growth with strong side-shoot development and a very long flowering time of around 14 weeks. The seeds are feminised and photoperiod, so flowering only begins after the light cycle is switched to 12/12. From the same breeder, you will also find Amnesia by Vision Seeds in our shop; another Haze in our range is Super Silver Haze by Green House Seeds.
Who Is Brainkiller Haze For?
Brainkiller Haze demands time, space and know-how; we list it as a strain for experienced growers. It suits:
- Experienced growers who can plan for around 14 weeks of flowering
- Sativa and Haze fans looking for a classic old-school profile
- Indoor growers with a tall room who have the pH value under control
- Outdoor gardeners in southern or Mediterranean climate zones
- Experienced consumers who appreciate a strongly cerebral effect
It is less suitable for beginners and for regions with a short summer, because outdoors harvest is not until November. You can find more potent strains under seeds with high THC content.
Growing Brainkiller Haze: Indoor & Outdoor
Indoor Growing
Indoors, according to Vision Seeds, Brainkiller Haze needs about 14 weeks of flowering – considerably longer than most hybrids. The breeder states 600 g/m² and describes the plants as tall, with strong side-shoot development. It expressly describes growing it as demanding: the strain reacts sensitively to the pH value and requires patience and experience. So check the pH value of the irrigation water and substrate regularly. With tall-growing Sativas it is also advisable to switch to 12/12 early and to guide the shoots horizontally with a net or by tying them down. You will find the basics on pH value and training in the Growpedia.
Outdoor Growing
Outdoors, Brainkiller Haze ripens very late: Vision Seeds names November as the harvest month and therefore recommends the strain more for southern or Mediterranean climate zones. Under ideal conditions, the manufacturer states a very high yield of up to 1,100 g per plant. In cooler regions, a harvest in November is a risk because of cold and wet conditions; a greenhouse can extend the season. Also plan for plenty of space and sturdy supports. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Brainkiller Haze
Vision Seeds describes the scent as classic Haze – spicy, lemony and slightly floral – and the flavour as herbal with light citrus notes. The manufacturer speaks of a typical old-school Haze terpene profile but names neither individual terpenes nor lab values. It portrays the effect as powerful, long-lasting and psychedelic: strongly cerebral, euphoric, creativity-boosting and extremely mood-lifting. In its words, this is not for the faint-hearted or for to-do lists; it recommends the strain to experienced consumers. With around 22% THC and a low CBD content, Brainkiller Haze is very potent. If you have little experience with strong Sativas, you should approach it slowly. How intense the effect is depends on dose and individual tolerance.
