Jack Herer Sensi Seeds Cup Nr.7 [1994] 1. Platz Cannabis Cup
Sensi Seeds - Jack Herer
This multiple Cannabis Cup Winner is undoubtedly one of the best types of marihuana in the cannabis world today. Named in honor of world famous global hemp activist and author of the most informative book on hemp and cannabis, `The Emperor Wears No Clothes`. Many years of extensive breeding and special selection gave way to this multiple Haze hybrid that will deliver good yields of heavy clustered, medium density buds glistening with juicy, resin coated Haze bracts that have a fresh and peppery, pungent Haze smell mixed with a hint of fruity skunk. Jack Herer has an award-winning flavor of strong peppered Haze spiced with a delicious dash of fruity acridness and the effects have a quick onset with a strong uplifting cerebral high and a giggly edge.
High Times Magazine: The bud was heavy with crystals and resin; the high was immediate and cerebral. An excellent strain.
Flowering: 50-70 days
Height: 150-180 cm
Yield: up to 125 gr
High Times tells about the lineage:
While Sensi say the exact lineage is a closely-guarded secret, it is accepted that Jack Herer is a 3-way hybrid of Skunk #1, Northern Lights #5 and Haze. The precise lineage is probably Haze x [Northern Lights #5 x (Northern Lights #5 x Skunk #1)] which suggests that Sensi began by selecting a male from their NL5 x SK1 seedline (AKA Shiva Skunk) and backcrossing him to the NL5 female cutting. As Sensi purchased Neville's breeding plants, they had both the Haze A and C males, so it is likely that they then chose a female NL5 x (NL5xSK1) plant and pollinated it with one of the Haze males to create Jack Herer., this would make Jack 50% Haze, 37.5% NL5 and 12.5% SK1. This gives Jack Herer a similar composition to Super Silver Haze and Mango Haze which are 50% Haze, 25% NL5 and 25% SK1.
