Critical Jack is a mostly sativa variety from Silent Seeds and can be cultivated indoors (where the plants will need a flowering time of ±63 days) and outdoors. Silent Seeds' Critical Jack is a THC dominant variety and is/was only available as feminized seeds.

Silent Seeds' Critical Jack Description

This variety was developed using the same clones that created Critical Jack by Dinafem, combining Critical+'s fast and profuse flowering and Jack Herer's vigour and Haze character. It is a plant with explosive results in every sense of the word.

Critical Jack is composed of 60/40 Sativa Indica genetics, with vigorous, homogeneous, versatile and resistant plants. It offers good results in all conditions, also outdoors where it shows good resistance to insects and diseases, withstanding many pests.

Critical Jack, in indoor cannabis cultivation, is ready to harvest in about 60 days of flowering, with a yield of about 625g per m2 under optimal conditions. Outdoors the harvest is ready between late September and early October. It is a very vigorous plant, developing large shrubs outdoors. Silent Seeds advises to limit the vegetative growth period or prune it to control the final size indoors, as it shows a pronounced stretch when it goes into flowering.

Critical Jack by Silent Seeds, big buds with a Haze flavour
Critical Jack's harvest consists of large, fleshy flowers with swollen calyxes covered in a sticky, terpene-rich resin layer. The flavour and aroma is dominated by a Haze character, with woody cedar, pine and incense notes, all accompanied by lemony hints on a slightly sweet and earthy background inherited from the Critical+ line.

Critical Jack produces a Sativa effect, stimulating and euphoric nature that promotes good mood, chatting and creative activity.
