Critical Jack Autoflowering – A Truly Jacked Strain

Critical Jack Autoflowering attains its name from its parent lineage, Critical Plus 2.0, and Haze 2.0 Auto. This autoflowering, feminized beauty loses none of the astounding flavors and effects of the original. In her short life cycle, she’ll bestow you with resinous, dense and elongated buds that’ll give you a perfectly balanced high. Critical Jack Autoflowering is a strain that’ll grow with vigor, quality, and ease.

Its autoflowering genetics are no detriment to its astounding qualities, and you can expect yields that’ll make any grower proud. Both indoors and outdoors are suitable environments for this jewel. When indoors, Critical Jack Autoflowering requires a plethora of light. Use nothing less than a 600W HPS lamp on a 20/4 light cycle if you want her to show you what she’s really capable of. Make sure at least 30% of your substrate is coco coir since her roots love air. At the end of her life cycle, typically 70-80 days, you can expect an ample yield of up to 100 g/m2 of glistening, delicious buds.

Critical Jack Autoflowering is no stranger to the outdoors but is inclined towards warm climates with lengthy summers. Expect her to reward you with multiple yields of up to 230 g/plant if grown in the right environment. She’ll be ready to endow you with her gift in early April or late October.

  • Nutrient requirement: High.
  • Keep in 10-20 Liter pots.
  • Watering Schedule: Frequent but don’t overwater.

Powerful Flavor on a Balancing Act

Critical Jack Autoflowering doesn’t compromise on quality from its non-auto counterpart. Intense citrus, cedar, and earthy spices will all dance on your palate. A calming euphoria will overtake your body as your mind becomes unclouded. If you want a truly easy to grow strain coupled with astronomical quality, this is the one for you.
