Critical Jack is a slightly Sativa-leaning, feminised cannabis strain of award-winning pedigree. Birthed by Dinefem from two all-time greats, Critical + and Jack Herer, she shows off a brilliant mix of three legendary strain heritages: Skunk #1, Haze and Northern Lights. Critical Jack’s world-class reputation is exceeded only by her quality – high-yielding, intensely powerful, superbly flavourful and a sticky trichome goodness worthy of elite extractions. Worthy of finishing at the top of any podium.

1st prize -Outdoor category- at the V Copa Cata Zona Norte (Buenos Aires, Argentina, September 2019)
1st prize in the 'Outdoor Sativa' category at the 2016 UCLA cup (Unión Cannábica Latinoamericana).
1st prize in the "Best Shatter" category of the 2015 San Bernardino Hempcon Cup, USA.

Owing to slight Sativa-dominance, a branchy and open structure allows the perfect amount of light and air through, in order to fully maximise these first-class yields. She can grow to a heighty 3m outdoors.

Critical Jack yields dense, bulky buds that are completely covered in trichomes and she does so in highly rewarding quantities, making her ideal for highly-ambitious or commercial growers.

A richly complex flavour profile that’s both potent and sweet – a woody, spicy, incense, pine and lemon combo.

Expect a powerful, lengthy psychoactive experience that is uplifting and energetic, thanks to the Sativa influence of Jack Herer. This mostly cerebral high is perfect for clear-headed socialising and carrying out daily tasks.

Critical Jack is a real grower’s delight. She’s strong, fast-growing, happy in humidity, and resistant to plagues and moisture-related problems. With that said, she thrives optimally by means of SCROG and SOG indoors, and in warm, sunny, Mediterranean climates or greenhouse conditions outdoors. Due to her large size and potent smell, outdoor greenhouse or guerrilla growing methods are best to avoid unwanted attention.
