Type and genetics

The feminized marijuana seeds Cobalt Haze of Sensi Seeds are the result of crossing Blueberry, Afghani and Silver Haze. These are pedigree parents whose union has sought to preserve the sativa effect of Silver Haze, as well as add the fruity flavor of Blueberry and the production and large buds of Afghani.


Cobalt Haze grows vigorous and branched with a medium-long internodal distance. It is a variety that, due to its sativa influence, can reach a more than considerable size, especially in outdoor crops.

Therefore, it is important to keep in mind that we are talking about a strain that stretches a lot during the flowering period, especially if it is to be grown indoors, in tents or grow rooms, because if the vegetative period is not well sized, it could give space problems.

Aroma and taste

The aroma and taste of this variety are exquisite and, in this sense, you can notice the great influence of its tasty Blueberry parental, known for its fruity and sweet notes, which are transferred to Cobalt Haze, along with an earthy and incense background. The most trained palates will also be able to detect some slight Skunk-like citrus touches.


The effect at the beginning is powerful, active and mental; then it becomes relaxing and very pleasant. The best of both worlds united in a hybrid that transpires quality on all four sides.

Some users describe the psychoactivity of Cobalt Haze as very pleasant sensations, and consider it an ideal strain to consume at the end of the day, to share a good time with friends, or to use against stress.


Cobalt Haze is a great producer, that's why it is the favorite of those growers who want to ensure an outstanding performance without many complications, as it is an easy to grow variety that with little care offers harvests with large buds full of resin.

The production is high both in indoor and outdoor cultivation, an all-terrain strain that is synonymous with good results.

Flowering in indoor cultivation

It is harvested in approximately 9 weeks, after the pertinent vegetative phase. It is a variety that "stretches" during the flowering period, something to take into account when calculating the space to avoid problems.

Flowering in outdoor crops

It is harvested in mid-October in the Northern Hemisphere and in mid-April in the Southern Hemisphere, a strain with a medium flowering period, which requires an extra wait compared to other faster varieties. However, the enormous quality of its harvests makes it worth the wait.
