Jack Herer: This ganja warrior transcended into a perfect strain

He was a legend, a legalize-it warrior, a cannabis campaigner ... Jack Herer was as real as the streets. To commemorate his achievements for the cannabis culture, Greenhouse Seeds concocted the perfect hybrid that would live up to Jack Herer’s legacy. The hybrid was coined as Jack Herer, obviously.

The ancestors of Jack Herer are Haze and Red Skunk. By the way, we mean the ancestors of the strain, not the person, although it would explain a thing or two. Red Skunk derives from the classic Skunk. Haze genetics derive from California, where breeders were mixing the dankest sativa landraces during the 60's to 70's. They collected strains from South America, South India, and Thailand. Their genetics traveled to Amsterdam, straight into Greenhouse Seeds’ hands.

This 60% indica-dominant strain delivers a complex high, including physically stoned sensations, together with cerebral highs. It’s a long-lasting one, so clear your schedule - you’ll be goofing around for quite a while. With its high THC levels, you can expect true potency. If you grow Jack Herer indoors, you’ll receive 800g/m² of buds. Outdoors, where Jack Herer thrives, you’ll receive up to 1200g/plant! It reaches medium heights and enjoys SOG and ScrOG methods.

This plant is an absolute pleasure. Seeing it develop from seedling to a full-grown plant, you’ll become attached to it. Enjoy Jack Herer, and enjoy the delightful highs. The amazing, uplifting nature of Haze shall reveal itself after the first toke. Greenhouse Seeds didn’t mention any awards for this strain, quoting that there are “too numerous to mention”. Ice cold. Jack Here is an absolute classic, renowned by ganja connoisseurs around the world.
