If you want a spectacular new hybrid, the recipe for this is straight-forward: Cross two spectacular strains. This is exactly what Dinafem did when they crossed legendary Jack Herer with the equally acclaimed Critical.  Dinafem created a top quality hybrid with Critical Jack that pleases growers and connoisseurs in many ways. Given its top-of-the-line genetics, Critical Jack is very easy to grow and flowers fast while having outstanding robustness and vigour. It won’t grow out of control which makes it a good strain for any growing spaces. As you would expect from a top strain, Critical Jack will grow thick and fat buds that will be oozing with resin at harvest-time. Critical Jack’s flavour is first class as well. She has an intense aroma that reminds of exotic wood, incense and spice which is beautifully accented with refreshing notes of citrus on top. She gives a cerebral, energizing and creative high that is long-lasting. Perfect for creative work, reading or watching a movie together with some friends. Buy Critical Jack Strain

Dinafem, with their classic hybridizing procedure, added Critical+ to Jack Herer to intensify the yields and shorten the flowering time to create this strain.

The late, great Jack Herer (1939-2010) was a marijuana activist, fighting to change cannabis law. “Legalize It” was his motto. The sativa-dominant hybrid Critical Jack, partially named after him, generates as much spirit as he possessed. If you’re into cannabis activism, this is the strain to utilize during activist gatherings. With 60% sativa and 40% indica genetics, it will lift you up while a smooth, relaxing sensation slowly takes over. Buy Critical Jack Strain

In 60 days, your ganja flowers will fully develop and provide you with 625g/m² of buds for indoor settings, while outdoors – brace yourself – you can expect up to 1200g/plant! That is definitely one of the highest-yielding plants that Dinafem has produced, ever.

This strain by Dinafem won the 1st place in the “Outdoor Sativa” category during the UCLA (Unión Cannábica Latinoamericana) cup. Also, Cracker Jack Extractions used Critical Jack during the Hempcon Cup, where they won the 1st prize in the “Best Shatter” category.
