Dinafems Critical Jack Automatic Description

Dinafem Critical Jack Automatic Critical Jack Autoflowering by Dinafem seeds. From the union of 2 superb clones that combine the highest production of dry weight in the shortest possible time and strength, plus the endurance and power of one of the best cannabis hybrid of history, born Critical Jack. The combination of this strain with our best autoflowering line, it has led us to create the express version, which in only 70 days from birth completes its life cycle. It is surprising the solid buds covered with large resin (trichomes glandular).

In the final crossing, the force and productivity was increased leading to a solid production.

It reaches up to 2 or 3 feet high under appropriate conditions, with lots of light, warm temperature, and an aired substrate. But it doesn´t grow much if the conditions are not perfect, yet quality is always good.

The quality of the final product is what makes the difference from less enhanced strains. Look forward to hard tight buds, strong odours, completely covered with resin, and intense sweet flavour, with hints of lemon and frankincense.

Buds covered with resin
Sedative effect
Caramel flavour.
CBD: high
Production: 20 gr - 30 gr

It took 82 days from seed to harvest. About 22 days in I started to see hairs and she took 60 days to flower. I grew 1 plant in a 2.5x2.5 foot tent under an HLG 135w LED. Light cycle was 20/4 it’s whole life. I used a fabric pot with 60%coco and 40% perlite. I used high frequency fertigation in a drain to waste system watering about 1L 3x daily of General Hydroponics nutrients. I also used a trellis net (Scrog) After drying and trim I had just over 7oz (200g) of dank flower and about 1oz (30g) of trim that was turned into about 7g of bubble hash. I cured it nice and slow. Very pleased with critical jack auto. Great genetics by Dinafem! this comment

Started one seed in 20l pot outdoor. Main cola was cut off by accident 5th week from seed. Plant responded well and grew strong side branches. Harvested good ounce of dry bud. The effect is very psychodelic and fun :) Tastes like pine and chocolate. Very nice plant. this comment

I grew a 10 inch tall plant that yielded 34 Grams. I used the LST method with heavy fan leaf pruning.

Dinafem recommends 20 hrs of light through the entire grow cycle. That’s what I did.

Plant starts showing pre-flowers around day 29 with harvest coming 71 days after the seedling sprouted.

180 Watts of full spectrum CFL.

80 CFM negative pressure exhaust system.

Scotts Hyponex soil

Probably the best strain I have smoked by now - and I was in Amsterdam too. I never expected this strain to be so strong, therefore I was enormously surprised about the result. It starts off with an enormously strong stoned, leading to a highly psychedelic experience. After one or two hours, the sativa-part kicks in, leading to motivation and even ability to party. If you are not smoking this strain often you end up with a little hangover which is best described as a little fog over your head. Grow was nice, had great results (25-30g per plant outdoors!). this comment
