Dinafems Critical Jack Description

Dinafem Critical Jack Critical has become the most well-known and intensely cultivated variety of cannabis in Spain over the past two years. The cultivating revolution caused by the arrival of Skunk to the US, and later to the Netherlands, finally reached Spain 20 years later, but under another name: Critical. The reason is that the Skunk#|1 genetics are dominant in this strain, which is also composed of an Indica variety of Afghani origin, a highly productive strain developed on the west coast of US, and which received the name of Big Bud. Mr Nice Seed Bank commerced with this hybrid, naming it Critical Mass. We could say that they became the “godfathers” of the most popular genetics in the whole country. Thank you, Shantibaba, Neville and Mr. Nice! You’ve done an incredible job! We owe you a few words of recognition because thanks to your hard work (and that of a few others), we have been able to create a truly popular seed. And now, we are going to try again, this time crossing our Critical+ with the most productive sativa in our catalogue of mother plants – the only one capable of flowering in 70 days, producing up to 21% THC, and yielding a dry weight similar to indica or hybrid varieties.
The results are obviously convincing: 60 days of flowering are enough for a harvest of plants that have a really rapid growth. Their aspect is shabby like the sativa, with ample knots and very large light green leaves that hang limply. An explosion of flowers are produced, totally covered with large crystals of resin, in a much shorter period than one would expect with a sativa. Who do we have to thank? The most established seed bank in the world, Sensi Seeds. Our thanks to you, too, for this marvellous plant which is simply impressive. The crossbreed we have produced with these two elite varieties does not have the effect of a pure sativa, but it does have a fairly strong effect, the effect of the Critical+, fairly well-balanced; the modification increases its psychoactive side. It has an intense fruity flavour, but in some samples this varied to a lemony taste of wood. Very productive, even more than Critical+, an authentic flower producing machine, flowers which are very regular in size and homogenously placed on the branches –an heirloom received from its Critical+ side -. There is a clear increase in strength, in exchange for a few more days till flowering, so what more could we ask for? Well yes, there is something else. A noticeable increase in resistance against damp and fungus. Nevertheless, if the weather is too wet or climate conditions unfavourable, outdoor plants can be harvested at the end of September.
The result is guaranteed to surprise.

High resin content. A slightly above average flavour being my only criticism.

The effect is mind blowing.. creative, thought pravoking and and very possitive. I must for people wanting to perform at there very best. Very sociable. This strain fires up the brain and makes you feel euphoric. Great for a meditation.

Dont pull too early as it can be an over stimulate and create anxiety/racy thoughts.

It may not smell or taste like the Cali strains but its better where it counts, in the head.. utter perfection.

Enjoy

great yield
i found a few distinct genotypes in the 20 seeds i cracked
no mould
fairly dense
the stretchier narrow leaf variety hits harder and is much more uplifting
excellent variety for both yield and quality
recommended

I liked the plants and the super hard bud shape, although the plants stay small after one pruning and don't drop too much. The finished product is actually not my coffee; The smell and taste is too hybrid, too plastique. The high is somehow nervous, racy and not really centered in the body, just putting on a brain lock after a period of smoking and increases sensory for anxiety. The high didn't comfort me at all, i actually stopped smoking this weed -- to get to the point :-)
