Genetics & Origin of Jack Herer
Green House Seeds describes its Jack Herer as a world-famous, much-awarded strain. The breeder gives the origin as Haze × Red Skunk and the ratio as 60% Indica and 40% Sativa. According to the manufacturer, numerous international Cannabis Cups are to its credit; they are not listed individually. Green House Seeds states the cannabinoid values precisely: 20.94% THC, 0.12% CBD and 0.04% CBN. The plant grows medium-sized and forms stable, branched shoots. The seeds are feminised and photoperiod, so flowering only sets in after the light cycle is switched to 12/12. If you would like to compare lines from other breeders, you will find the Jack Herer by Sensi Seeds in our range; Green House Seeds carries an autoflowering strain of this name with Auto Jack Herer.
Who Is Jack Herer For?
Jack Herer by Green House Seeds combines short flowering with large yields. It suits:
- Indoor growers who work with SoG or SCROG
- Yield-focused growers who want to harvest after 8 weeks of flowering
- Outdoor gardeners who would like to be finished at the end of September
- Fans of classic Haze and Skunk aromas
- Consumers who appreciate a complex, long-lasting high
If you are looking for a mild strain or a purely physically calming profile, this strong hybrid, which is also mentally stimulating, is less of a good choice. You can find more strains with a high THC content under Super High THC Content.
Growing Jack Herer: Indoor & Outdoor
Indoor Growing
Indoors, according to Green House Seeds, Jack Herer flowers for 8 weeks and delivers up to 800 g/m². The plant grows medium-sized and forms stable, branched shoots; because of this structure, the manufacturer recommends it particularly for Sea of Green (SoG) and SCROG. It describes the strain as robust in cultivation and advises good air circulation. With yield figures this high, it is worth supporting heavy shoots with a net in good time and keeping an eye on humidity in the final weeks of flowering. Peak values such as 800 g/m² require strong lighting and optimal conditions. You will find the basics on climate and training in the Growpedia.
Outdoor Growing
Outdoors and in the greenhouse, according to the manufacturer, Jack Herer is ready for harvest at the end of September (northern hemisphere). Green House Seeds states up to 1,200 g per plant. The breeder does not give a plant height in centimetres; it describes the plant as medium-sized. For yields of this order, it needs plenty of root space, full sun and a long vegetative phase. Supports for the side shoots and an airy location help to bring the flowers to ripeness dry. Only grow where it is legal to do so.
Effect, Aroma & Flavour of Jack Herer
Jack Herer has a spicy-sweet scent with Haze and Skunk notes. Green House Seeds describes the flavour as herbal and slightly peppery with a sweet finish – typical Jack Herer. The manufacturer does not give a lab terpene profile. It describes the effect as complex: deeply relaxing physically, mentally stimulating and long-lasting, in other words a combination of Indica and Sativa traits. It speaks of a strong, multi-layered high that can be felt both mentally and physically. As fitting occasions it names everyday life and the evening as well as creative activities. With 20.94% THC, 0.12% CBD and 0.04% CBN, the strain is strong. How intense the effect is depends on dose and individual tolerance.
