Description

Critical Jack is a feminized photoperiod cannabis strain carefully cultivated by the team at Dinafem Seeds and is one of the most popular strains in the Critical family. If you’re looking for your next powerhouse strain but can’t decide? Look no further because Critical Jack is just right for you.

A Critical + – Jack Herer Hybrid

Growing this strain outdoors is recommended in warmer climates as this strain has a longer flowering period due to her Sativa-dominant genetic lineage. While she has excellent resistance to mould and pests due to her high resin-production, growing in a greenhouse will improve the quality of the harvest. Outdoor crops can be ready to harvest late September/mid-October while indoors this strain blooms in 60 days to yield up to 625 gm2 under a 600 W HPS or LED lighting. Here is some further information to help you make the most of your grow:

  • Medium to tall plant – excellent for both indoor and outdoor growing.
  • Max EC of water – veg: 1.4, flower: 1.8
  • Water pH – 5.8 – 6.0.
  • Best grown in 10 L pots with 70:30 coco coir/perlite mix.
  • Grow room temperature below 26 ˚C to preserve full terpene profile.
  • SCRoG arrangement recommended due to tall branches.

Critical Jack - Perfect for Extracts

This strain has an excellent resin production making this an ideal hash plant – perfect for those looking to make their own cannabis extracts. In fact, this strain won first prize at the 2015 San Bernadino Hempcon Cup in the ‘Best Shatter’ category owing to its irresistible flavour and euphoric, relaxing effect.

      none
    • General impressions

      Great strain with a Sativa effect, I didn’t feel any Indica in it at all. Jack finishes its flowering really soon as well as starts it! on 12/12 schedule it takes only 7-10 days. I used 20l bags with 17l of soil in them, 2 400W HPS. As a result, 700+ grams from 3 plants in several stages of harvesting - the bottoms needed a little longer to finish. Colas are so heavy, after a month of flowering
      they’re gonna need extra support
