Critical Jack is a feminised seed from Silent Seeds with a sativa-leaning profile, roughly 60 per cent sativa and 40 per cent indica. It is bred from Critical+ and Jack Herer, and the breeder highlights strong vigour, consistent genetics and generous output. Plants grow tall with an open structure that lets light reach the lower growth and keeps air moving through the canopy during flowering. Buds are large, dense and weighty, with a noticeable coating of resin reaching the smallest leaves. The aroma is layered: a Haze-style character with notes of cedar, incense, pine and spice, lifted by a bright citrus edge from its Critical+ parent. The effects are described as energising and long-lasting, feeling more mental than physical, with a light psychedelic lift. The strain has won prizes in several outdoor sativa competitions. Indoor flowering is listed at around sixty days.
